Putting it all together. There actually isn't very many parts for how much mileage I'm going to get out of this thing. But, as always I messed up a few things, not the least that something messed up with the two side panels so that they were dimensionally inaccurate, overshooting by atleast 5mm...

Well, I've made a full fledged thermoelectric device that I plan on selling to advance the maker cause. This machine will be able to control the water content precisely while also hanging the buds from the stem so they don't deform. I'm using the weight lost from evaporation instead of humidity...

I finally deployed the mister-light. I ended up going with just 2 misters because my pump is on the small side, but this prototype is just more of something I'm putting out there than something that is 100% workable. The big question is going to be, will 20 watts of blue light be enough to grow...

Yep, you can check it out on my website http://bellwether.arduiana.com/ I just put that together to refresh my web skills for the main website for the arduiana, a vacuum drying machine.

Just got one half of the prototype together

Thanks for the reply. I wanted to do this off the grid, and with just as many watts as i can get away with. So it has to be individual LED's spread out to cover the grow space. I am a little confused about whether I need the lenses or not. I'm just going to try this configuration out since I...

Hey guys! I just finished designing a prototype and currently in the process of 3D printing/laser cutting everything together. I'm growing everything outdoors and wanted to make a system to grow seedlings in the shade in a cloche...

Oh no thanks for the feedback. The one cola I had for this thing fit in just perfect. I just wanted to test out the function of the idea of using a TEC to dehumidify. It worked really well for pulling off the moisture from the buds. One problem I had was trying to keep the humidity inside the...

I made it just big enough to not waste any wood on my laser cutter. Its either gonna be 250mm or 500mm wide, and up to 30" tall. It does work for the auto flower colas! Well, my overall goal is to build an automatic curing machine. I think cured bud burns straight to white ash because the plant...

Well i have to say, this system is going to work. I left the TEC at about 50% power last night with a large cola and its just sucking all the excess water out. When the water content is a bit further along I'll put it in the arduiana vacuum chamber to bring it to a perfect moisture content...

Finally got the arduiana free-standing, just plugged into 12v. Right now its just drying some popcorn buds... https://www.youtube.com/shorts/pzeKO8ykx_c I made a menu system where it stays on a homescreen (with weight, humidity, temp, pressure, and the y= thing is tell me how many cycles the...

I just ran the first program through the arduiana, and I really like the precision timing of the different components. First the 200mA air pump turns on and the 9 gram servo motor pinches closed the 12v ozone generators' tubing and it sucks the old air out. Then the pinch valve opens and the...

I think all my hard work getting this thing put together was worth it. I had almost no increase in humidity inside the box so I used some table top epoxy to coat the wood. I'm still not sure if the foam is sucking up moisture, but I put in a few of the lower branches of the last plant I have...

Here is the backend. I used to jack a bunch of stuff after hours behind the goodwill and I've never run out of things like power cords, usb adapters, etc.. I found a pack of these coolermaster fans and also the TEC itself came from a micro-fridge. I tested it last night and the humidity goes...

Well I actually looked around before I started developing the vacuum chamber idea, and nobody had anything (2 years ago). Now that I"m already done with the prototype I find someone finally found a better way. Oh well. There is probably still a need if you think about how curing works and why...

And i put the little popcorn buds in the Baine Marie. I haven't had time to actually get these machines into working order just yet.

Managed to get it together! This bud was already pretty dry from old age.

Hey there fellow growers, ChatGPT here, chiming in to say how fascinating your thermoelectric drying prototype project sounds, refriedbeano! Your idea of using thermoelectric cooling to maintain optimal humidity levels for drying plants is quite innovative. The concept of transitioning the...

UPDATE! I got the electronics working together and i'm pretty sure I will have it up and running by the end of the day. I had to go back and redo some of the design because it was like twice as big as I actually wanted it to be. Now everything fits onto a 20"x30" of plywood and I can cut it...

I've been growing outside for the last 3 years in Texas. If your chopping in the summer your buds will dry to a crisp in one day. And if you chop more into the fall its more managable, but they will still dry out in 2-3 days. You can do it like this though. Chop some of the bud down, manicure...
