Hi, Im just starting a project to turn my monome (monome.org) wireless using a la fonera box. My main problem is powering it all. I really like the look of the lithium stealth backpack but im in the uk and it comes to $80 with shipping! What alternatives are there out there? Am i being unrealistic need to power a matrix of 64 leds and send and recieve serial via the la fonera and aslo find a way to power that. I don''t mind having a sepearte power for the fonera but one solution would be ideal.
EDIT: Just to make myself clear: im using an arduino connected to a button matrix and an led matrix both 8x8. How can i power the arduino via a battery? Thanks a lot, Steve
