Ok. So! Back to hardware / electronics projects!! Yay!
This is a preview for an upcoming post. I am currently working on upgrading my Hacked Breadman Breadmachine TR444 Incubator from a previous project. I’m adding some RGBW neopixel LEDS from Adafruit for light. It will have a button to change lighting sequences from White to red/blue to purple, to blue, to black. All the colors one would need to 1. see into the machine. 2. Color LEDs to grow seedlings for gardening. 3. blue which may come in handy for bacteria cultures? IDK. maybe not. But whatever. I currently have the arduino code for the light sequence working.
I will also be adding a fan for circulation. I 3D printed the fan holder. I may or may not have a button to control the fan. I will have a big red button to start the incubator cycle (37 Degrees C for bacteria / fungal petri dishes). And i am considering another button for a programmed Dry Heat Sterilization routine. As mentioned before, according to Wikipedia:
The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour.
I also think i will be integrating my Chronodot real-time clock for use with this dry heat sterilization routine and possibly some other incubating cycle as well. Cool! Fun stuff! Lets get working!!
p.s. post in the comments if these are the kind of projects you’d like to see more of of! 🙂
So despite the blog and my internet presence being quite mute as of late i actually have been up to quite a lot. My homemade Lulzbot Mini 3d Printer this summer was a success, amd i have constantly been improving it. At some point i will take some photos of it’s final progress. A few of my pea breeding crosses from last year were successful, including one i’m excited to grow again which is a cross of the Purple Passion dark purple seeded pea (which is a small genetically weak pea variety) with another stronger pea variety. That should produce something really cool in the coming years. And this fall and next spring i’m experimenting with school by going through a Precision Machinist course and am learning how to use milling machines, lathes, and CNC equipment to produce Aerospace quality components. Not sure if that’s something i want to do long term, but they are skills i’m interested in and can use throughout my life. So that’s new.
Anyway though, as a throwback or a revisit to my post in 2010 titled “Do Plants Really Need Sunlight?“, which has actually been one of the most visited posts on my blog over the years, i finally got around to building a few of those coils that sounded so interesting.
So the basic premise or idea behind using a coil of wire with electricity is that it produces a small amount of electricity or a magnetic current through the air. This is the same idea Nicola Tesla was after all those years ago when his imagination was captured with the idea that everything could have wireless electricity. And in many cases his dream has come true with an ever increasing amount of technology these days using induction to wirelessly power or heat things. The basic premise of applying this technology to plants comes from an articlei read once that talked about how researchers were able to measure a small direct current from trees in a forest by placing nails in them. They then had ideas about placing nails in many trees and hooking them up together to power small electronics like a battery or cell phone charger, or a smoke alarm. Basically all plants (and maybe all living things) produce a bioelectric field of energy. If one can tap this field to harvest electricity, then why cant we tap into it and feed these plants with extra electricity to help them grow.
One question i asked in my old blog post was if plants even need sunlight at all as long as they are getting some form of energy to grow. I still haven’t done an experiment to test that idea, but it’s still an interesting question. Because it makes me wonder if there are ways plants could be grown in complete darkness.
Regardless, this summer i finally built a prototype plant coil. I built it rather late in the season, so i really wasn’t able to give it a good test. My original plan was to plant 3 or 4 genetically identical tomato plants near each other in the relatively same soil with at least one plant being the control. I was then going to observe over the course of the summer f the tomato plants within the coils had larger and better growth than the control. That was plan anyway, i just didn’t quite get to it.
You can see here we were trying to use a volt meter and another coil to see if we could detect that our coils were working. We weren’t having much success with the meter in the beginning and i don’t remember if we did later after increasing the power supply a bit. But in theory you should be able to measure with a second coil.
I placed it on three smallest tomato plant clusters in the very late planted tomato patch. Interestingly enough, the three plants it happens to be on might be the only three blue tomato genetic varieties that survived my haphazard tomato disasters this year. Since placing the coils on these plants i have noticed an improvement in them and they have since catched up to the growth of the other tomato plants in that spot. Although at the same time i did also make a furrow and started watering them more. But even so i’d be willing to go out on a limb and say that the coils did help them go from “runt” status to catching up to the others. I may yet get a few tomatoes from the larger two before winter hits. Thanks to Gilbert for providing the motivation to actually build this project. And a thanks to the Homegrown Goodness plant breeding forum where i get so many of my adventurous gardening and plant breeding ideas. You guy’s are the best and a continual inspiration to me.

So, while my experimentation was a bit haphazard this year i think i still did ok. It was a fun project that went from an interesting patent to a cool project idea in my head and at the back of my mind, to a fully functional project / prototype. Plus i think these coils look cool. haha.
But it makes me wonder what other cool patents are out there that i can exploit, reverse engineer and build to experiment with. One of my next projects i think will go the opposite route and will be heavily steeped in Open Source as i think i will try and build a “Food Computer“. Basically it’s a small climate controlled aeroponic grow box. It should allow me to continue my plant breeding efforts even in the winter which is really what i want. Plus it will allow me to learn more about this “urban gardeng”, “vertical gardening”, and “aeroponic” stuff. I can’t wait to get back to pea, bean, and tomato breeding even though the summer and fall are waning fast. I think i’m going to repurpose my 2ft x 2ft t-slot frame that i was intending to turn into a large 3D printer and/or CNC mill. But it’s still going to be a long time before i finish that project, so i figured hey why not actually use it for something useful in the meantime! So.. that’t the plan.. 😀
I finally leaned how to buy a domain name, and figured out how to use Ubuntu to host a website. It’s really interesting. On the one hand, starting my own website isn’t as hard as i thought it would be and is quite liberating, and on the other there are so many technical things associated with it that it’s actually harder than i thought it would be. So technical in fact that it approaches the very upper limit of my computer skills.
The Domain i bought is BioLumo.com for those who are interested enough to check it out. Be aware that my HTML skills are rather crude, and at the moment i’m hosting it myself, so it could very well go down at any moment. The name was chosen to attempt to be understandable by both English Speakers and Esperanto Speakers. Bio Luminescence in English, and Bio Illumination in Esperanto.
Anyway, so what does it actually take to create a website? Well, first you have to get over the idea that if you think of a website name that nobody else has ever thought of, that in theory it should be free. Strangely enough you MUST purchase a domain name from a Domain name registrar. The one i chose after reading several reviews was name.com. They have decent prices and good reviews. So yeah, you buy a domain name and pay a yearly subscription fee, or you can pay for more years in advance.
2. You need someone to host your website. I eventually don’t want to go to all the hassle of hosting my own website in the future, so i will probably pay someone else to host it. I’m thinking people who are computer geeks and open source fans. Yeah, Laughing Squid looks like a great place to host. They also seem to have awesome price rates on their cloud servers (Amazon EC2?).
This time i set up an old Ubuntu Computer to serve as my webserver. It took a bit of work. Not too much, but a little bit. I had to install Apache and FTP. I had to configure a few other things as well. The hardest part was trying to set up the permissions on the /var/www folder, because otherwise my server locks everyone out from accessing my website files.
Anyway, yeah. This is the first time i have ever had my own website. Hope i can figure out some cool stuff to put on it.
Mi estas elprovas nova retejo. Mi estas gastiganta ĝin min sur malnova Ubuntu Linukso maŝino. La Domajno mi aĉetita estas BioLumo.com por tiuj, kiuj interesi sufiĉa rigardas ĝin. Esti konscias, ke mia HTML kapabloj estas iom kruda. La nomo estis elektita provi esti komprenebla per ambaŭ Angla parolantoj kaj Esperanto parolantoj.
