I don't have a Teensy yet, but am investigating the feasibility of building a battery powered display using OctoWs2811 and up to 10m of 5v ws2811 ribbon. This combo looks like it has awesome potential, especially once I found out there are FFT routines in the core of teensy!
I already have a load of 18650 LiOn batteries I'd like to use, which are 3.7-4.2V. Does anyone know if it's possible to power the ws2811 ribbon with 3.7v direct from the batteries? It will obviously not be as bright, but I wonder if it would work at all?
Failing that, I guess I would need to wire two batteries in series to get ~8V, and use something like this - http://www.ebay.co.uk/itm/Turnigy-D...sGames_RadioControlled_JN&hash=item35cc96f49f , or this - http://www.pololu.com/catalog/product/2111 - but it would be easier and more efficient to not require the regulator.
thanks, mark
