Joule Thief. I know how they work, but is a joule thief self-regulating and self-limiting? Is a varying input (DC) okay?
Joule Thieves. I know how they work (my one works fine) , but is a joule thief self-regulating and self-limiting?
Could I hook it up to a 12V source?
Is a varying input voltage okay? -- Will the voltage/current across my white LED (should be 2.6VDC absolute max) be too high or surge?
I would like to know if it would be suitable to use on my motorcycle to drive an additional LED or two for a headlight supplement. The voltage varies between 11.5VDC and 18.2VDC.
I have a basic handmade circuit, with a hand-wound toroid and a generic transistor, usually running from a stable 1.1 to 1.6VDC, I have tried it with a 9V cell and it seems to work alright, but I want to be sure before modifying it/or my motorbike.
Any help much appreciated! 8-)
