I have a friend that wants to hook my drum set's double-bass pedal so that everytime I press it down, it'll light up these kind of LEDs around the 22" diameter bass drum head. Each pedal would be hooked up to approximately half the circumfrence worth of LEDs. His friends in EE suggested that 8 AA batteries for each pedal would be enough, but 16 AAs seems to be a lot. I play drums and kick the pedals at a very fast rate, and we would like to know if plugging them into an outlet (using a 12 VDC power supply) would be safe, given the speed/frequency that the LEDs will be turning on/off. Would it be a fire hazard?
I apologize in advanced if any terminology is off. I myself know little-to-nothing about electrical engineering. (Also feel free to re-tag/re-subject this question - I wasn't sure what to put).
