on the back of my mouse it says 5v 100mA.
Does this mean if i want 4leds i need to have them 25mA or less?
also i messed up my mouse and i plan on using an old printer usb. Are all usb's 5v?
Finally there is a cylinder thing attached the the wire of my usb. I have no idea what is is and would like to know if when i cut it i should keep that part or cut below that.
