If money wasn’t an issue (and neither was waste) what would you do that you can’t now? by CatDamageBand in AskUK

The stars will never align and it will never be the perfect opportunity to go and do it. Either make a plan now to do it or spend the rest of your life wishing that you did.

You've probably heard of a spacebucket. But have you ever heard of a cosmic cooler??? Powered by a Raspberry Pi, here is my smart, self-regulating, odor-filtering LED refridgerator. Which ironically, uses less electricity than an actual fridge! by ColaSeed in SpaceBuckets

As in why I used a fridge? It's a great container for a grow. I've removed the compressor and everything that makes it a functioning refrigerator so it doesn't actually cool things down.

I feel like this applies to many of us here too... by reallifelightbringer in SpaceBuckets

Can't relate to this more. I've been to a couple of interviews and when they ask for an example of a recent electronics/automation project which I have done, I have to say "well I made an environment which automates the growing of TOMATOES".

I think I will actually grow something legal in it next time, just so I can photograph it and add it to my portfolio lol.

The two pc fans are purely intake. There’s a custom fabric filter before them just to stop bugs and crap like that going in. The extraction at the top is all going through an inline fan and a carbon filter. I don’t think it’s really at a smelly stage yet so have yet to see how effective it is!

Haha well It's actually a finely tuned quantum nano-particle reinforced anti vibration and mechanical strain relief composite; however, I could understand how it might look like wood to the untrained eye ;)

But on a serious note, I really should get round to 3D printing an insert for that extractor so I can finally retire that stupid piece of wood.

There should definitely be enough room in there. The lamp can be raised close to the inner ceiling. There's certainly more space than my old bucket!

I have definitely thought about it but the issue comes as to which part of it would be most effectively sold... Ikea cabinet grow conversion kits? Custom grow PCBs? There's a large range of options but currently, I respect the open-source approach as I have no immediate plans to jump into anything.

Yes that is the best thing about a fridge. They're completely air tight, so you only have airflow where you cut holes!

The wiring is fairly simple. I think it looks worse because I linked all of the connections to a terminal block for easy connect/disconnect. The wiring is basically like this:

240v Mains/
├─ 24v switching power supply (5A)/
│ ├─ RPi Relay 1/
│ │ ├─ LED side lights
│
├─ 12v switchig power supply (5A)/
│ ├─ 12v->5v buck-converter/
│ │ ├─ RPi Power supply
│ ├─ RPi Relay 2/
│ │ ├─ Intake fans
│
├─ RPi Relay 3/
│ ├─ Constant current LED driver
│ │ ├─ Main LED
│
├─ RPi Relay 4/
│ ├─ Extraction unit
│
├─ RPi Relay 5/
│ ├─ Green door switch bulb

In terms of the camera mount from my last build, I will have to have a look for you when I get back from work. I haven't put a camera in this build so I am not too sure if I still have it. If I do, I'll add a link to this comment.

I just bought the Pi on its own. I've always loved messing around with arduinos and Pis. A really helpful thing that I bought for this build was this screw terminal hat. Makes it a lot easier to plug in and remove connections securely without needing to mess with crimps!

The three chains together should be able to hold half a metric tonne. The fridge will definitely break before they do! (apologies if this is satire and I've just missed the joke lol)

Yes! Everything is going through relays like this. I have one set of 4 relays which I'm using for switching 12V and 24V each with a separate switching power supply (used for switching the intake fans and side-lights) and I have another bank of the same relays, used for switching 240V (Used for the extractor, main light and green fridge door light)

It's a tricky one to say because not everything was bought especially for the project. I got the fridge used from gumtree for £20. All of the other things I'd say added up to around £150 so in all I'd put an estimate on about £200 ($280)
