ATARI PUNK CONSOLE

556 timer

additonal 555 timer clock with pulse fade function controlling the CV of the APC

if you want to add the pulse fade LED timer to it, you'll need another 555 circuit like below. 

Just take the output pin 3 from the 555 and attach it to the CV pin 11 on the 556

These two circuits MUST BE on the same battery and same ground line. 

Slow it down more? PLEASE CHANGE THE 220uf capacitor to two 470 caps in series, this will make the pulse A LOT slower!!
