I am looking at perhaps selling these at some point, but still have a bit of work to do in regards to enclosures, as it'll probably need something custom.
I have custom designed the PCB to fit nicely atop a 400mAh single cell LiPo. It runs an ATTiny85 (which I'm just now finding is going to be pushing it flash memory wise, but should be doable) with a V-USB based bootloader, a LiPo charger IC, and a boost converter. It's controlled entirely from a single pushbutton, and so far has 4 user define colour modes, adjustable brightness, and 3 fixed animated patterns.
Currently testing the battery lifetime, and so far I'm up to 45 minutes with the battery voltage at 4.04V, running a rainbow scroll effect at a fairly high brightness on 9 LED's. It's a pretty fun project of 3D modelling, PCB design and programming, and looks pretty awesome in the dark





Really quite difficult to get a clear picture of, though. Either overexposed or underexposed



Just something to look at
