I have some pen hosts lying around that I'm itching to put together, but as I'm pouring through my diodes, I'm realizing they're all around 6V minimum forward voltage. The hosts I have can tolerate 2xAAA, so as far as I know I'm limited to ~3V.
Have any of you run into similar issues? The best idea I've come up with from here is just trying to find diodes I like that happen to want 3V, though I don't know of any places that make it easy to sort products as such.
Otherwise I'm looking at using some specific boost converters I imagine. I'm having trouble finding decent ones that are about the width of a AAA so that it'll fit in the host.
Any input?
