Cooling Coaster: The 12V Test!
Aug. 3rd, 2023 04:46 amSo, I've been stressing over nothing, it seems. I'd been under the impression that I'd need to build a whole control circuit, with multiple switches (power, heating/cooling, and intensity), on a circuit board, putting a PC power supply on my desk, it turns out none of that is necessary for testing purposes!
This realization has led to me dropping a PC power supply on my chair, plugging a PC power supply adapter board into it, unplugging the Peltier device from the original control board, and somehow connecting it to the adapter board.
And it worked just fine!
I don't know if it got colder, but it definitely got cold faster! A very worthwhile effort!
Unfortunately, I didn't realize that the PC power supply had a fan in it, nor that it would be loud enough to be distracting.
Fortunately, I now know that I don't need a huge array of controls (after all, I only use it to cool drinks, not warm them. Nor do I need to change the voltage the Peltier device runs at), as well as knowing that I can use almost any 12V supply for this project. Time to look at my other options!
