Hello, I'm considering squatting in a empty building that I found. The building is huge at least 1/2 acre big, but the downside is its on a college campus (even though its a fairly remote part) and the grass looks like it was periodically cut. I was able to explore only a small portion of the building, but I didn't even have to force an entrance since there was an opening toward the back part of it. I haven't tested whether or not electricity works, but I was able to find a circuit breaker inside and I'm thinking that if theres no wifi nearby I'd have to generate my own internet via WiFi server that uses a cell phone card, but converts that to WiFi. Another downside is its difficult to park nearby because oncampus police would see my car in trespassing territory. Should I go through with this or am I better off living in my car. I can post pictures

Okay, /diy/ (No clue what you guys call yourselves)
I'm trying to design a simple circuit that will supply power to a small heating element and then stop supplying said power. It's not my first foray into making a circuit, but it's the most complicated one I've ever tried to make. I have several requirements:
>Must be compact
>Must pair to a smartphone
>Must be in a constant state of readiness
>Low power consumption
>Low (~$40) cost
I figured a simple Bluetooth circuit could act like a switch and relay (could it?), and that would solve most of my problems. I'd also like to run it off of a hearing aide battery. Preliminary research says all this should work.
I'm asking how you guys would approach this problem, if anyone has any tips for working with Bluetooth, and looking for critiques on my idea.
/k/ommando mostly here. I'll dump some stuff to keep this bumped.

I came up with this idea yesterday, for a room air filter attached to a peltier junction to produce both clean air, and a source of drinking water (1-3 gallons/week, tops). Larger atmospheric water generators use much the same principles in their function.
I'm considering drawing up more viable plans and building this in the near future, but I thought I'd see what people thought of the idea. Waste of time? Pointlessly inefficient? I'm not sure, myself. I don't know a lot about the efficiency of peltier junctions, but I don't think the temperature differential required to produce a dripping of water would be all that much. I would assume that the efficiency drops the greater the differential across the junction.
I'm just not a fan of countertop distillers, and I like to use deionized water for my iced tea.
