Rattlesnake Mountain


Marriott Ranch is a 4200 acre cattle ranch near Rattlesnake Mountain, about an hour from Washington, DC. I had the chance to accompany my autistic daughter on a youth trip there during this past week.

About 150 youth spent three days re-living the Mormon handcart trek - no cell phones, no computers, no microwaves or ovens, no flush toilets. I didnt take a camera, so the image above is a shot from the internet showing the views near Hume, Virginia, and looks like the blue skies and green landscapes we saw.

We pulled handcarts along the trails south of Rattlesnake Mountain. One stretch we will all remember was the ascent of Killer Ridge - where the men and boys were pulled away and forbidden to talk with or help the girls. Id heard about the "Womens Pull," but it was another thing entirely to experience it. The way was full of rocks, eroded trail, and tree roots - entirely difficult even had it been flat terrain, much less the steep side of a mountainous ridge. Because the weather was lovely, they had us go all the way to the top of the ridge. It was intense in a good way and possibly the most physically challenging thing I have done short of un-anesthetized childbirth.

As we camped by the river the second night, most were thinking how hard it had been for those early folks who settled the Western United States. I was thinking about how life is now for so many who dont have access to electricity and plumbing, and how life will be in a post-oil era, whenever that might happen. But there was also the wonder of walking within feet of longhorn cattle (without an intervening fence), watching a crane soar through the sky over our camp, seeing the blanket of stars above us as our campfires died out, and washing in the sparkling waters of the Rappahannock River.

Towards the end of the last day, my daughter told me, "Momar, I dont think I want to do this after all." But that was when we were already on the track home, walking towards the cars that would take us back to our electricity-served modern lives. And it was really the only time she complained, beyond the constant refrain of "My feet are starting to get tired, Momar."

One of the girls captured my feelings well when she said "It was a cleansing experience."

Epic solar boat adventurer Watt meter

Not so long ago I bought a watt meter online and it arrived as described.

I love it when that happens.

The best part isnt that it actually works, and works as advertised (which IS nice), but it tells me my Epic Solar Boat Adventure might actually work. 

I have 360w of solar, and it turns out my motor draws about that same amount of juice when running flat out. 

Hopefully that means I can cruise for a few hours a day at speed  4 of 5 on a sunny day, and still end the day with a full battery in case of snake bite, internet use, phone use, wanting to shine floodlights into the eyes of the local wildlife in that way that we humans tend to enjoy... whatever.

In all these years, Ive never really known how much power my trolling motor uses on full power. My multimeter couldnt handle the amperage my motor draws, so I only knew the values for the first 2 of 5 power settings. 

Today is a happy day.

My trip is going ahead.

This stuff is going to work!

Arc Controller Motor Shield More Power!!

The August 21 article "Arduino Motor Shield, Arc-Controller Launched By Arc Robotics" gave me a good reason to do a little research on microcontroller (MCU) motor control and motor shields.
Arc-Controller motor shield

The article covers the Arc-Controller, a new high capacity motor shield that has a Kickstarter campaign in progress, telling us:
"Maker, developers and hobbyists that enjoy building Arduino platform based projects might be interested in a new Arduino Motor Shield called the Arc controller which has been created by Arc Robotics...“There have been a lot of amazing projects come out of the Maker revolution, however, many are limited by the capability of their motor controller. We want to change that. The Arc-Controller is a bridge to bring high Amp motor control to your projects, up to 43 amps with a heat sink. It is capable of variable speed and direction control over a single Stepper Motor or two DC motors, because when do you only need one motor. The Arc-Controller is compatible with about any Arduino, or other micro controller such as Raspberry Pi. It runs an ATMega328, and is user programmable via the Arduino IDE."
The Kickstarter campaign still has 36 days to go, but it has gotten off to a very slow start, with only $927 pledged of the $41,500 funding goal. According to the Arc-Controller Kickstarter page,
"The Arc-Controller built around two H-Bridges. Each one can supply 43 amps of continuous current, with a properly mounted heat shield. The dual H-Bridges run separately, controlling two high-end DC Motors or as one controlling a single stepper motor. Built into the H-Bridges are current and temperature fail-safes.  If they begin to get too hot, or if they exceed the maximum current levels, current limiting will take affect. They will automatically shut down until they cool off, or until conditions are safe to operate. We also have included a reverse polarity protection...There is an integrated circuit on board that gives a current reading from the H-Brides to see how much current each individual motor is using. This gives you the option to write your sketches to react under certain loads, detect shorts and over heating states...We are creating a simple library that can be used to easily send commands to the Arc Controller. These commands can configure the Arc Controller to run a stepper motor, drive two brushed DC motors, and even an integrated an XY thumb stick “Arcade Drive”. The interface library will take input from you and transmit it to any number of connected Arc Controllers...We have had lots of success with tank style robots to the point that we made it run on two wheels until you want it to act like a tank. then it will lay down and drive like a tank. We have many theoretical uses, that we are eager to try such as: home made Segways, drive-by-wire go-karts, RC lawn mowers..."
There are a fair number of existing motor controllers for Arduinos if the Arc-Controller is overkill
for your needs. Here is a sampling of whats available for Arduino:
Adafruit motor shield V2
  1. Adafruit Motor Shield V2 for Arduino -- $19.95 -- "We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements...Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries...Instead of using a latch and the Arduinos PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C...5 address-select pins means up to 32 stackable shields: thats 64 steppers or 128 DC motors!"
  2. Pololu Dual MC33926 Motor Driver Shield for Arduino -- $29.95 -- "This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation."
  3. Ardumoto - Motor Driver Shield -- $24.95 -- "This is a motor shield for Arduino that will
    Ardumotor from SparkFun
    control two DC motors. Based on the L298 H-bridge, the Ardumoto can drive up to 2 amps per channel. The board takes its power from the same Vin line as the Arduino board, includes blue and yellow LEDs to indicate active direction, and all driver lines are diode protected from back EMF
    ."
  4. Monster Moto Shield -- $69.95 -- "This is essentially a ramped up version of our Ardumoto motor driver shield. For this monster shield we’ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We’ve also beefed up the support circuitry so this board is capable of driving a pair of high-current motors!"
  5. EasyDriver Stepper Motor Driver -- $14.95 -- "The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 20V supply to power the motor and can power any voltage of stepper motor."
If you use large motors or lots of motors on your MCU projects and could really use the Arc-Controller, you may want to head over to their Kickstarter page and support their campaign. If you know of other motor shields that do pretty much the same thing, send an email to arcatabob (at) gmail {dott} com and let me know what you use or recommend, and Ill update the post with that info.

Loss of Appetite

UPDATE 8/9/2012
I know it must seem like Im always correcting myself with these updates, but Im documenting the learning experience and attempting to pass on knowledge as I learn it.  Many times it appears that I have understood the problem at the time, but as more information appears this changes on occation.  

A few days ago I found small red worms, and at first thought they were Camallanus, but it turned out to be Midge.  Midge is a great food for fish, and it was only after transferring my fish to the raft so that I could better care for them that I figured that out.   The fish have not shown the excitement they used to show when fed, and I wonder if this is because they were feeding on Midge worms, and have become spoiled.  Simple fish food must seem tasteless to them now, and I suspect this is the reason for their lack of appetite.

ORIGINAL POST:
For about six weeks my fish have not been eating as aggressively as they used to. 
They have been showing signs of breeding, and
I attributed this to the loss of appetite.

But it was about the same time I added Dr Iron iron chelate. 
The iron made the water quite brown, and I also observed some algae on the walls of the tank, and in the water which I attributed to warmer weather. 
So the cloudy water did not concern me, and
my assumption remains that iron chelate is not harmful to the fish, but its definitely not to be dismissed.   
The Iron Chelate level has dropped from 0.5 ppm to 0.1 ppm over the past three weeks.  Today I bumped that up again with 60ml of
Dr Iron .
 
Before the fish began to loose their appetite I began to allow the salt levels to become depleted in an effort to see what affect if any a 0.15% salt level has on plants.
I let the salt level drop to zero over the course of a couple months.   That experiment was trashed when a leak developed in my grow bed, and I had to remove all the media and plants. 
The bacteria took a small hit but I was able to preserve, and restore the bacteria within a few days by using a small wet/dry bio filter.
Two days ago I began to bring the salt levels back up since I have very few plants left in the grow bed to experiment with.  Im now using this system for starting seeds and growing outdoors in my other system.

After bringing the salt up to only 0.9% the water cleared the fish began to eat better.
Ill continue to watch the fish to see if their appetite continues to improve, but since I have several variables going on Im still trying to figure out what it is that caused the loss of appetite.   It might be simply salt levels, but I feel that there is more to it than that.  Maybe there was enough algae in the tank to keep them satisfied. Im also  pretty sure they are also eating their young even though I have tried to provide a safe areas for the fry to escape into.


I added FE2 today, so I should be able to tell if this is the cause or not.  Ill update this post as I learn more.

UPDATE July 22, 2012 
After adding the FE2 on July 16 the water became dark again.   The fish seemed to feed a little less aggressively, but they did not ignore the food like before.  A week later they are eating better.   Dr Iron contains Phosphate 5%:  Potash (K2O) 8%;  Iron (Fe)  8%  so there are other ingredients beyond FE2 and it may be that this may be causing the fish to temporarily eat less.

Miss Utility changes my plans

The reason my fish tank is full of petals...


The weather has been beautiful, and so I decided it was time to start digging the planned 18" hole for my sump.

Turns out there are utility cables buried I want my sump to be. I was able to dig the sump a few inches down without interfering with the utility lines, which should be enough, if not as much as I hoped for.

Since I cant go down deep, Ive decided to ditch the sunken walkway idea and go upward instead.

The fish were in the 100 gallon tank I intend to use as the sump. In order to move the tank, I drained all but 2-3 inches of water out into the 150 gallon tank. In the process I was able to see all the fish. In addition to the minnows, there are still a surprisingly large number of blue gill and redear.

One of the blue gills looks much larger than any of the fish I plopped in the drink on March 18. Ive never seen the blue gill or redear eat food Ive tossed in the tank, so either theyve not needed food, have slurped old food/insects/leaves off the bottom when I wasnt looking, or theyve been snapping up minnows at their leisure.
______________________

Since the permanent structure can only be 52" tall, I plan to make it so the roof can be easily and securely elevated when needed. When I get it done, Ill be posting pictures of the greenhouse with the roof in both the raised and lowered positions.

In the mean time, its just been lovely to be able to be outside in my yard during this time of year - something Ive never before bothered doing in the 14 prior springs Ive spent in this house.

Insomniatic Throw Up

According to my spell check, insomniatic isnt a word. Thats ok...Im sure you can all figure it has something to do with insomnia.

Well thats exactly how I feel right now...wide awake when Id normally be asleep. Its not too late though, but still. There are three major things bothering me right now and they may surprise you.

1) Jobs.
Now this doesnt seem like a surprise to anyone that knows me...likely. Well truth be told. Where I live, I am at the mercy of what mom brings home. However, what she brings home is typically leftovers. Every blue moon, I get fresh food at home. Great...but comes with a catch. Whats that you say? I will be expected to eat whatever for at least two - three days. Another thing my mom bullshits with is dinner. "Oh I ate. Dont know why you didnt," she would say. "You ate at grandmas," Id say back with a glare. "Why didnt you come over?" "Because I had class/you forgot me at home/I didnt know they were having dinner!" Times like these lead to dinner-less nights which often get me into trouble...especially when I sneak in a secret stash of desserts mom has.

So I really want a job so I can eat fresh food at least three times a week. That would be nice.

On top of that, mom runs the power bill and doesnt manage money well in my eyes. Id like to move out. When she decided to splurge on company parties, fixing a car that had "Im NOT WORTH IT" written all over it, my sister that blows money on even dumber things...but doesnt pay the power bill so we have a poorly insulated freezing cold house during a storm....well that was a sure fire way to get me to NOT want to stay.

Im still waiting for that $130 she owes me. $100 of it was stolen.

2) Pets
Call me paranoid but Im having a huge freak out about the death of pets. Three died within two months....not something Im thrilled about. Six rats...I will likely be trying to rehome them if I move out on my own. However there is a high chance that if Im on my own for sure, they will stay. In 2nd place on the worry list is Tux. Since I didnt file taxes or have proof that my mom is a California State worker struggling, I asked my dear friend Ashley to have Tux done and Id pay her for it. This means he will be in her name and I have to have the license transferred over. No big deal...but Id really like to take home "my" cat. And in 1st place is my beloved Spyro who turns 10 March 28th. I have already had a dog die and I felt like he died in a crappy way and wasnt treated to my standards. Id like for Spyro to not go out the same way. Call me shitty but Id rather have him euthanized than to die in his sleep. I just dont do well with dead bodies. However this means Spyro must be in the best of care till his body just cannot function anymore. It wont happen if he continues to live at my grandparents house. As far as the dead body thing...well as much as I love all of my pets, theyre just harder to let go when you have had them for this long.

3) Marriage
Bet you didnt see this one coming. Adam told me he didnt want to get married...ever. Well ok whatever. But I do. I sat back and thought to myself...I wonder why he doesnt want to get married. Is he scared? Then I asked myself why do I want to get married? Am I scared? I cant believe I am going to admit it...but maybe I am scared. The problem isnt Adam...its me. Maybe Im afraid of him leaving or maybe Im just insecure. Whatever it is, I have realized that it is my problem...not his. I admit it. I want to get married because of my personal insecurities. I think it is a big lump that could later affect our relationship. First step, admitting. Next, fixing. Will work on that later.

So now I feel much better with all of this stuff off my head/chest. Still not tired but thats probably because of too much Dr. Pepper. Since you got this far...here is trivia.

In 1972, Dr Pepper sued the Coca-Cola company for trademark infringement based on a soft drink marketed by Coca-Cola called "Peppo." The soft drink was later renamed Mr Pibb.

Nubian goats Ontario Canada ◍ Meet Nabob and Mocha our coffee coloured goats ◍

Pet Nubian goats

Nubian goats

Grass fed goats

Goats in Canada permaculture
This is mocha, hes a wild one. He loves eating/licking things hes not suppose to ( pressure treated wood, chicken coops, clothes on the line ), But he also enjoys the good stuff like watermelon, cantaloupe and oats. His favourite game involves head-butting anyones hand, but of the two, hes the baby of the bunch, always needs a companion and CANT be alone.
Anglo-Nubian Goat
This is Nabob, He is gentler then mocha and he use to be inseparable, but has recently been gaining courage, bravely trotting off around the property. Hes much pickier the Mocha and doesnt like fruit, just his oats, grass and maybe a few trees.

Aquaponics Venturi adjustment

I thought Id make a little adjustment to my venturi as suggested by Mike Creuzer in a comment on this post on my Venturi air thing.

He thought I should have some extra bubbles breaking the surface, and it turns out its a bit of a hot topic in great debate all over the place, but I noticed a very slight oil slick on the surface of the water. I guess lots of things case very slight oil slicks. Eucalyptus leaves for one. Uneaten fish food probably would. I suspect an oil slick - and Im talking an almost invisible one - would have some effect on gaseous exchange between the atmosphere, and my fish tanks water.

I have no idea if thats true, but I figure it couldnt hurt to stir the surface a little.

So I trimmed the pipe carrying water and bubbles down to the bottom by an inch or so and now lots more bubbles exit.










A 1/4 second exposure shows how much extra water movement on the surface is actually going on.










After only a few seconds there was no more sign of the oil slick.

Winner The first 120 things in 20 years competition

So a while ago, I bought a MPPT solar charge controller.

It turns out the nice ebay based company I bought it from was a fraud, and sold me a product that wouldnt work with my solar panel in spite of my having asked them and then double checking. My solar panel had too high a voltage, but the listing said it would be fine.

Anyway...

The result was that I was sent a product that didnt work as advertised.

Eventually ebay made them give me my money back. The company insisted I return their product at my expense.

I posted it to their registered address, but the post office in China said there was nobody by that name at that address.

So China Post returned it to sender.

Me.

All this is old news to anyone who follows this blog, but this is the new bit.

I thought Id give it away because its of no use to me, and might be exactly what someone else wanted. But who to give it to?

I thought Id hold a competition, and give it to the winner, but I cant think of a decent theme.

The current plan for the first ever 120 things in 20 years competition is to run it through the invention engine and see what it thinks.

so... stay tuned I guess. Its late, and Im going to bed.

Tomorrow, the competition begins!

Epic Adventurer Thinking something actually happened

Something actually happened!

I did something.

I secretly fed a duck and a turtle in a park near a hospital (Where there are "please dont feed the wildlife" signs, but I picked at the bark and leaf litter on the ground, and fed other bits of the wildlife to the other wildlife, so I figure...

Wheres the crime?

anyway... they looked hungry and made pleading sounds, so I fed them some other things

but I guess I DID feed them things that (if I could read exoskeleton facial expressions) looked very frightened, and screamed in utter misery the entire time...

But anyway...

after that, and more importantly, I have more stuff in my brain that I did the other day.

and that feels a little odd

Its been a while.

Ive had a tummy ache.

They thought C17H19NO3 might help so gave me lots of it for ages.

Lately it feels like theres been a eighteen month slow leak of stuff from my brain rather than the thing I was going to say but forgot a bit...

So Ive got that going for me.

But today I continued on from the other day, and actually finished some work on my solar boat that may have actually got me a little closer to something.

Which is nice.

It doesnt sound like a lot. To anyone who hasnt tried to make a trailers wiring communicate with a cars wiring it wont sound like a lot, but if you have, and you know either something, or nothing about electronics, youll know that having your brake lights strobe when you turn left is actually a reasonabe outcome. At the very least, the person behind you knows that something is about to happen, and they should probably change lanes and get as far away as they can.

Not such a bad outcome as far as safety is concerned.

But what works even better is a system that uses the correct lights where they are appropriate!

Who knew!

But the best part, is that I wired it up, hot glued it in place, plugged it in...

And it actually worked.


Today at least, physics does my bidding.

Heres the problem!

After experiencing what appeared to be an iron deficiency I began adding MircobeLift Iron Cheate 60ml at a time.   The levels would come up slightly, and then drop out of sight and the plants were not looking any better.  When I began to run out of MicrobeLift I shopped locally and found Dr Iron which boasted 8% iron chelate.   I had my doubts and so I tested the strength of two iron chelate products.  MicrobLift does not specify the percent and I think I know why.  Heres the results and my method of conducting the test.


I started with 0.5 ml
added 200 ml of distilled water
this gives me a dilution of 0.5/(200+1) = 0.00249

then taking my next sample from this dilution, I repeated the procedure resulting in a 0.00000622 dilution.

Assuming the product is 8% FE+ as claimed then two dilutions results in 0.5 parts per million which is mid scale on the FE test.





Here are the results of testing equal amounts of both MicrobeLift and Dr. Iron


This first picture shows the Iron  and the second shows the Chelate Iron



Dr. Iron = 0.25 ppm
MicrobeLift = 0.0 ppm

Dr. Iron => 1.0 ppm
MicrobeLift = 0.0 ppm

I tested a stronger sample of Microbelift and verified a trace amount of Iron Chelate, but Dr. Iron is less expensive for more product and provides a substantially more concentrated dose of iron chelate .  In fact Dr Iron contains over twice as much Iron Chelate as they advertize! But its in the form of EDTA which requires a low pH.

MaxiCrop Seaweed with Iron claims 2% iron chelate and is a favorite among other aquaponic enthusiast, but I did not test that product. 

Here are the real world results.    In the weeks ahead of switching to Dr Iron I had applied 1-1/2 bottles of MicrobeLift with meager results.  Two days after using just a small amount of Dr Iron the plants have begun to show obvious and rapid improvement.

MircobeLift
Dr. Iron  2012-06-23_1731
Dr Iron 2012-06-24_1810
I have continued to add 25ml of Dr Iron to the 1000 gallon system once per day and when I add the iron I pour it directly on the Hydroton as I did with the MicrobeLift.

Update:
Today is Tuesday June 26 2012.
This mornings test showed that the level of chelated iron was nearly the same as yesterday!  The chelated iron may be normalizing after only three days of dosing with Dr Iron as opposed to MicrobeLift.

While the two beds show a significant difference in growth, the raft system has become healthier and is showing a lot of promise.  The foliage has become green and the plants are beginning to grow again.

Dr Iron is a far superior product.  Im guessing MicrobeLift is making an effort to sell something that will not change the color the water in an aquarium.  But I think they should state the percent in order to be more honest about the product.

Dr Iron has caused my water to take on a brown color, but this is a aquaponic system not an aquarium so to really is not important.
The tomatoes have grown up around the basil since my last photo.  The basil on the left is from the raft. 

Look at how much the basil in the gravel has grown!

This is the basil in the raft.  It has regained most of its color and it doing much better since I switched to Dr Iron

The raft is clearly stunted and anemic, but I have hopes of a full recovery
Dr Iron is great, but it may not be available. So Ill address iron products in general.
This is from Green House Grower
There are many chelating molecules available, but only three that are commonly used in horticulture: EDTA, DTPA and EDDHA. These abbreviations refer to the chemical structure of the organic molecule. In general, manganese, zinc and copper chelates are only found in the EDTA form. In comparison, there are three forms of iron chelate, FeEDTA, FeDTPA and FeEDDHA, although the most common form is FeEDTA.
With iron nutrition, the form of iron is very important. The three common chelated forms (iron-EDDHA, DTPA and EDTA) differ in their ability to hold onto the iron (and therefore keep iron soluble and available to plants) as the media pH increases. Between a media pH of 4.0 to 5.5, any form of iron will work (including iron sulfate) at supplying iron to the plant. However, as the media pH increases above 7.0, only the iron from Iron-EDDHA has high solubility. Research has shown that the ranking of iron forms from most effective to least effective at supplying iron at high media pH is Iron-EDDHA > Iron-DTPA > Iron-EDTA > Iron sulfate. If iron is applied in a form that is not soluble because of high media pH, then most of the nutrient will not be available to plants until media pH is lowered.

In general the best products will say EDDHA because they work over the widest range of pH

This article at deseretnews.com may also help while shopping for an iron product
Other less-expensive products are also available. One widely sold product, Ironite, contains iron sulfate.
Holt explained Ironite has a "high sulfur content that helps to temporarily acidify the soil around the plants, so work it in around the plant, and then water it in. It works well on turf and on some plants if the soil pH is not too high."
"Another product we sell is called Dr. Iron," he said "It is 22 percent iron and 55 percent sulfur. It basically takes iron oxide and covers it with molten sulfur. As the sulfur dissolves, it releases the iron."
IronSul Soil Acidifier with Humic Acid is another way to treat chlorosis. It is acidic, so it lowers the pH, making the iron more available. It also has a small amount of zinc to supply that micronutrient.
Foliar sprays to the leaves often produce a quick response, but they are inconsistent and temporary.

CHALLENGES CHALLENGES

Going Beyond....

I was wondering over the last couple of days if any of you may be interested in thinking beyond the envelope, beyond Aquaponics. Not necessarily doing, but just reading, absorbing or challenging your thoughts. So Im going to include anything that might be of interest that I consider a possible offshoot from A/P. If you are interested and wish to delve a bit deeper, please let me know and Ill endeavor to include further information in that area.

One such example is Cloning. The process of taking a section of a plant and making it possible to identically reproduce this plant as many times as you need to. Now to give you a taste or two.

I do hope you realise that as we are in Aquaponics, we are bound to the basics of Hydroponics and we are very fortunate as we have untold experiences from Hp to aid us because what ever problem we may have in relation to plant growth etc. They have probably had the same many times over.

Likewise the fish we keep and grow have all of the problems that any other fish have and at times more so because of the particularly crowded environment we may have them in at various periods of their growth. So both aquaculture and even your local aquarium dealer and be a source of important advice under certain circumstances...

Rant Over, Back to the notes...

....and there will soon be an organic garden and an aquaponic freshwater system for farming tilapia; that is, for raising the fish symbiotically with plants.

It is the mission of Santa Cruz Aquaponics to produce the healthiest, most flavorful and nutritious fresh Tilapia and Watercress available on the Northern California market.

Rene LaMarche of Port Orchard is growing tomatoes and other produce using a technique called aquaponics, which combines aquaculture and hydroponics. (MEEGAN M. REID | KITSAP SUN)

 it seemed a little like they just kept throwing things up, and yet somehow it works.  this one is a triple-decker aquaponics system.  the bottom layer is a tank with 8000 tilapia swimming about.  in order to aerate and filter the water it gets pumped up to the top layer where the tomatoes are growing.

NOW, A Small scale aquaponic system in Barbados
Long before the term "aquaponics" was coined in the 1970s the Aztec Indians raised plants on rafts on the surface of a lake in approximately 1,000 A.D. 
The one that gets biggest the fastest needs put in another tank. Quickly. Atila only has 19 friends left. They are all his friends, because he ate his enemies... 
I hope you all enjoyed that one...Well thats another one done....

From this oinon Ill do some proof reaing,nd tryto edit it so its actually readable.


I bought some baby spinach from my local supermarket today, and thought Id plant it out rather than just eat it.

It looked a little sad so it only cost a few cents.








But There was a decent root mass so I thought it might be viable.











I trimmed all the sick looking leaves and think I now have some baby spinach plants.

Ill post  an update in a few days after cutting off all the leaves that will inevitably die, but I  think the plants will survive.

Mutli Phase Humboldt MCU Garden Project

As yesterdays Humboldt Laser Harp post indicated, the microcontroller (MCU) music group project is well under way. So now Im thinking about how to get the second group project started in the Humboldt Microcontrollers Group, one involving gardening.
MCU and sensors for potted plant

Several people whove been at Humboldt Makers Group meetings or the MCU group meetings have said theyre interested in MCUs and gardening. And it seems like lots of other people in Humboldt County might have an interest in ways to improve gardening. There are lots of organic gardeners in the area, and agriculture has been part of the Humboldt economy for much of the areas history. So Ive decided to outline a multi-phase approach to a collaborative project focused on MCU gardening. And a significant part of this collaborative project will be identifying and reaching out to Humboldt people who are involved in gardening or agriculture and might be interested in sharing their knowledge and / or participating in this project.
MCU and hydroponics

Two long term goals I have for the MCU gardening is to be involved with a successful hydroponics system and a successful aquaponics system. There are lots of websites and projects on the Internet that tell a person how to do hydroponics or aquaponics, but Im an engineer, and I like to understand what Im doing. Plus I dont have a lot of money to spend on these projects. So my preferred approach to MCU gardening is to start out small, and get more complex after I understand the technology and green thumb art involved with each part of the MCU garden project.

Below are proposed MCU garden project phases. If we get the right people involved with the project and if we can secure funding of some type for the project, we can move very quickly through the phases or work on more than one phase at a time. So if you know people whod like to participate in this project or know of money that can be used for purchasing electronic components and supplies for this, please contact me at arcatabob (at) gmail {dott} com. These are the proposed phases for the Humboldt MCU Garden group project:
MCU and aquaponics (from dzbc.org.cn)
  1. Grow one plant indoor in soil.
  2. Grow four to eight plants indoor in soil.
  3. Grow four types of plants outdoor in soil.
  4. Grow one tray of plants indoors in hydroponic system.
  5. Grow three types of plants indoors in hydroponic system.
  6. Grow one type of plant in aquaponics system.
  7. Grow three types of plants in aquaponics system.
Phase 1 of the Humboldt MCU Garden project is simple and low cost and will help us learn the basic principles of MCU gardening. Phases 2 through 7 can easily be redefined as we get more people involved in the project and we learn more about what we dont know about MCU gardening.

The first draft design of the Humboldt MCU Garden project includes:
  1. One type of plant.
    LEDs and lettuce
    1. Lettuce is my first choice, partly because of whats being done with optimized lettuce mcu gardening in Japan and other places (see my blog post "LED Lettuce, The HydroTower And LED Humboldt Hydroponics.") We might be able to find useful data about optimum growing conditions for lettuce (light wavelengths, relative humidity, nutrients, temperature, etc.).
    2. If other people who want to participate in the Humboldt MCU Garden project prefer to grow something other than lettuce and have information about good growing conditions for that plant, Im willing to switch from lettuce.
  2. Growing container.
    1. The type of growing container probably wont be too critical for Phase 1. Mainly something large enough to hold the soil and drainage system that will provide good growing conditions for the plant.
    2. A five gallon plastic bucket is one option, especially if we can find a free one.
    3. We need to figure out where the container with the plant and MCU Garden system will be kept. It seems like Phase 1 should mostly be indoors because that means we dont need to have a rain-proof system. But having a Phase 1 container thats easily movable would be nice so we can roll or carry the container outside on nice days.
  3. Growing condition sensors
    1. Light sensor -- very important so we get good photosynthesis (and good respiration?).
      One type of light sensor (from Adafruit)
    2. Soil moisture sensor -- very important because too dry means dead plant and too wet means dead plant.
    3. Temperature sensor -- important for growth, especially during Humboldt winters. Temperature will be less critical for plants like lettuce, but very critical for plants like tomatoes.
    4. Relative humidity sensor (RH) -- RH wont be critical for lettuce growth in Phase 1, but it will be critical as the projects future phases try to minimize water usage and as we try to grow RH-sensitive plants like redwood trees.
  4. LEDs for indoor gardening
    1. RGB LEDs will let us adjust the light if we want
    2. Red and Blue LEDs appear to be used for optimum lettuce growth.
    3. Research and / or people who know plant growth lighting and LEDs are required.
  5. MCU to gather and record sensor data
    1. Which MCU we use for the Humboldt MCU Garden project depends partly on who wants to be involved with the project.
      1. If we can get a sponsor for the Humboldt MCU Garden project, such as an MCU manufacturer or distributor, Ill use whichever MCU they manufacture or distribute!
      2. If no MCU manufacturer or distributor sponsor can be recruited, the MCU will be determined by whoever takes the lead on programming for the project.
        1. If Ed takes the lead, well probably use a Texas Instruments MCU.
        2. If Josiah takes the lead, or if Im filling that role, it will likely be an Arduino or Arduino-compatible.
        3. If someone other than Josiah, Ed or me volunteers to lead the garden-variety programming for this project, that person can choose the MCU type.
  6. Type of soil
    1. Determining what type of soil to use will require research or a project member who has good experience with growing plants indoors in containers.
    2. The type of soil will likely affect other gardening aspects such as what nutrients we need to add and the soil moisture measurement.
  7. Fertilizer and trace nutrients to add
    1. Fertilizer and trace nutrients is another topic that will require research or a project member experienced in the art.
    2. Might want to evaluate whether pH or some other batch or continuous sensor (pH? nutrient analysis?) should be used to track nutrient levels.
  8. Data gathering and analysis
    1. There are no specific requirements for data gathering and analysis for Phase 1 since its such a simple system. However, part of the purpose of Phase 1 is to learn how to effectively monitor growing conditions, so it makes sense to establish good gardening data practices (GGDP) for those growing conditions and different types of sensors.
    2. As part of my goal to get Humboldt people more involved in the Internet of Things (IoT), it would be good to use services like open data bases and IFTTT (If This Then That).
    3. One gardening data goal is to use that data to automatically track, alarm and interpret the data generated by the sensors. It would be nice to generate online graphs and have alarms sent out by IFTTT when growing conditions reach or approach setpoints where action needs to be taken.
The above outline give you an idea of what I think Phase 1 of the Humboldt MCU Garden group project should look like. Next steps for me to get this project rolling are (1) talk to and try to recruit a couple people whove expressed an interest in MCU gardening, (2) promote the project to other people in the Humboldt Makers and MCU group and try to recruit some of them, (3) develop a one-page MCU project proposal that I can use to pitch to potential sponsors, and (4) continue to do research for Phase 1 topics like sensors, nutrients and soil types.

If you are interested in this project or know someone who might be, please email me at arcatabob (at) gmail {dott} com or come to an MCU group meeting or Humboldt Makers meeting in the near future.

Chitin ☜ the all natural pesticide disease correction in plants ●●●●☺

We have been very interested in chitin as of recently, weve always used worm castings in our grows, even hydroponics,  but never knew of its amazing qualities in bug prevention and disease correction, we just thought it was our special touch, lol, how naive the human brain can be.
But just recently thanks to john from growing your greens.com
( http://www.youtube.com/user/growingyourgreens )
gave a wonderful talk about the benefits of chitin and where you can get it. This got me to researching and found its one of the most abundant sources of natural polymers, has healing benefits, treats disease on trees, and repels insects just to name a few. I found an article online with an extensive list of ideas on how to use it, create it, and where to pick some up. HERE YA GO
http://idigmygarden.com/forums/showthread.php?t=51481

and if your into worm composting this is a great site to help you along with making teas and such.

We were also lucky to have stopped by the local hydroponics expo recently
( homegrown Hydroponics expo)
Not only are we very excited over there snap together piping but, they had a product there that was fertilizer from insects, this seems like a great idea, we will doing a controlled experiment very soon with this product, Will keep ppl updated on the progress and results.
Masked Hunter nymph,

all if a sudden Im seeing bugs Ive never seen in Canada before, 
what in the world is that????? a bug covered in dust? 
YUP!! Meet the masked hunter nymph, for some reason he thought my studio/office was a good place to roam. wish I could have got a better shot for ya but he was a quick little bugger.
