I've picked up a Mintyboost v3.0 and I'm very interested in adapting it to solar. I noticed you have made a solar powered Mintyboost, but it abandons the AA platform in favor of lithium polymer.
I'm wondering whether/how I could connect a solar panel to charge the AA batteries using some combination of the circuits from the mintyboost and/or the usb/solar/lipoly kits (and/or why you've opted to bypass the AAs for liPoly and whether I should, too)?
Is switching from AA to lipoly a major leap forward in efficiency (even if I used 4 rechargeable AAs in series instead of 2)? ...My main motivation for Mintyboost was the use of rechargeable NiMH AA's - I have lots of them floating around in circulation, and until I decide to trash them all, I'd like to continue to use them due to the convenience of their interchangeability for different uses.
Right now I'm stuck on how to solar-ize my Mintyboost. Any thoughts would be appreciated!
