- kragen 3y agotrue, but it's challenging to get a boost converter, even a very simple one like a joule thief, into the space of this earring; i think it's too small for a millihenry. using a larger number of smaller batteries might be a better option
- crote 3y agoTrue, but that's still going to consume more energy - not to mention the boost circuit probably taking up more space than the additional battery.
- dekhn 3y agoIt looks like you can get reasonable SMD boost chips and pack them and their entire support infra in <10mm https://hhtronik.com/product/uboost/ https://hhtronik.com/product/uboost/ which is about the same as two batteries as used in this project.
