I'm looking to build my own instavap for beekeeping mainly to save some money and because I enjoy DIY projects. The challenge I'm facing is finding a PID controller that operates on 12/24V DC since I want to use my 20V tool batteries for power. I've noticed some controllers advertise needing a 12/24V DC input but then claim to output 110/220V, which confuses me. Does the output voltage actually matter in this case? Am I misunderstanding how these controllers work?

You might want to consider if you actually need a PID controller or if a simpler thermostat would suffice for your project. After doing some research, there are thermal switches that could cut off at specific temperatures, which might work better for what you're trying to achieve without the complexity.
Yeah, a simple thermal switch could prevent overheating pretty well, though it may lack some of the precision you get with a PID. Weighing the pros and cons is definitely key!
It sounds like you're on the right track. PID controllers powered by 12/24V DC typically use that voltage just to run the unit itself. They send a low-voltage signal (like 3-32V DC) to a solid state relay (SSR), which then switches the high voltage needed for your heating element. So just ensure your PID can run on 12/24V and your SSR is rated properly for what you're planning to heat up.
And if you're feeling adventurous, there are also analog PID controllers that can drive heaters directly, which might simplify things if you want to design your own automated system.
Exactly! I noticed a lot of sellers use vague specifications, making it hard to figure out the exact functionality. Just keep an eye on the details, and you should be good.
That’s an interesting point! I guess if I can avoid overheating the oxalic acid while still ensuring effective vaporization, a simpler solution could be the way to go.
