Oh dude, don’t get me started on RPI projects! I need to get a new one, myself because I sent the last one out to a friend that really could have used a computer to bring around with him when he needed it so I stuffed it full of pretty much any video game you can think of and sent him out an xbox controller to go with it. Works fucking PERFECT. Those things are swiss army knives. I’ve personally made several projects with the ones I had, first one being an automatic plant watering system - I put some pictures of it in this thread
I think further down I’ve got the guts of a project that I didn’t start yet but have (almost) all the parts for - a homemade dab-rite. I would have made this a lot sooner but I got gifted a legit Dab-Rite shortly after.
But really if you think about it RPIs can be used to replace damn near any piece of expensive growing gear we use. Think about the bigass titan controls full room units that handle fans, AC, co2, etc - the logic to it is very simple and easy to either steal code for or just figure it out yourself (i’m no programmer, myself). Simple checks every XXX seconds to query the sensor. Say you have it set at 1200ppm for your desired co2 setting, sensor gets queried and it’s a simple ‘if X = desired amount shut off/stay off, if X = underneath target amount, turn on/stay on’. At that point though it’s finding the gear robust enough to take that many amps but at this point industrial automation has advanced where there’s ‘pi-like’ boards that are meant for way more beefy things. The one that caught my eye lately is…

Linus Tech Tips on YT I think a year or two ago actually reviewed several raspberry pi style boards that have the full GPIO pin set too and this one seemed to be far and away the most potent in terms of what’s under the hood while still being able to handle the Raspberry Pi operating system without issue.
Fuck now I wanna finish my Dab-Rite project… I still wanna make a temp sensor held by a GI Joe or find an old Toxic Avenger action figure
Fun fact, I actually had one of these as a kid. Toxie fuckin rules.
