(I have first year industrial electrician schooling) What i need is hard to explain but basically I have a xylphone type instrument and i want an LED to stay on for 2 seconds or so when a key is rung. i want an LED for each individual key. having a corded hammer (the thing you hit the keys with) is definiatly an option to carry voltage or whatever, and i need all this in as small as a space as possible. is this possible to be done easily and cheaply or even at all? please help.
