Hello,
After building the sequencer, everytime I plug in a power supply, they work for a minute or so, and then the voltage goes down to .001 volts, and I have to order another one online. What could cause this?
I'm on 3rd powersupply. They keep dying, and heating up.

Sounds like a short on the 5V rail. Measure resistance between pin 3 and 2 of the 7805
