Edited the BitBeacon (light emitter circuit). Created a square wave oscillator which feeds into a square wave to sine wave filter circuit. We amplified the sine wave signal and used that signal to drive an NPN transistor which lights the IR LEDs for the BitBeacon. We also created an additional circuit that lights a red LED with the amplified AC sine wave. This gives us visual feedback on whether or not the circuit is oscillating and not just railing.
