My hope is that a diode and capacitors will straiten it out enough for a LM317 to regulate the current reliably.
Yes, that is one reason, another is that I have them, the 3. is more irrational.You prefer AA/AAA alkaline instead of using lithium ion rechargeable batteries, because your host requires them for their size?
I have more or less come to the same conclusion. It just looked so promising.I dont think the joule thief circuit will provide a usable amount of power, and if it does, it will vary greatly with battery condition (internal resistance). Perhaps you could power a 5 mW red from it, but not something that consumes in the order of half watt or more.
