When you've run out of parts to build one?   :P



What is the point you are trying to make here?

Sorry, I know an LED works with a Joule Thief because it lights on and off so many times per second it looks on - so it can be used there, But is there a type of device that wouldn't work if powered by an oscillating current?

There are plenty of devices that would not work if powered by a JT circuit.  But, there are so many types of JT circuits too, different freqs., different duty cycles, etc.

I am not sure what you are getting at here?  I mean, you can not run your computer on a JT, coffeemaker, TV, Heat pump, 3D printer, or any device designed to operate on a fixed 60 Hz input, if you are talking AC devices.  For DC, since the JT is simply upping the voltage and switching on/off at a certain duty cycle, just about anything that has to have a fixed dc voltage input and a constant current to operate would not work with a JT circuit.

Just my opinion,
