Hi, Im still having problems with this one. I connected the circuit back up to have another go at fixing it but the PIC doesnt seem to work properly at all now. When the 555 isnt connected the chip will turn on and flash some LEDs (to show its alive) then after a few seconds it resets itself. With the 555 connected it does the same thing but flickers slightly during the flash pattern.
I connected my picoscope up to see whats happening. Ive uploaded a screenshot of it. This is with the audio circuit (with the big capacitor) disconnected and with the 555 connected. This is the most variation the circuit could possibly see but it doesnt look like its enough to cause any problems
