Thanks for the pictures! Any reason why there are three different colours? I assume the functionality is the same.
Grand plans? I await with great anticipation!
If they run fine off a single 3.7V, that's great news! But I would love to have a lightsaber which can go long intervals before needing to charge. How long would you expect a single battery to last? Most likely I could be using the sabre for practice for a period of up to 2 hours. I'm happy to try cramming more cells in the chassis if it means longer runtime.
I did not mention mini-USB at all. As far as I know, mini-USB is a dead interface type. Having looked further into what 'breakout' means, USB-C is not feasible (seems to have upwards of 10 'pins') and I will probably use a breakout board for a micro-USB connector.
