hack-o-mat vending machine

• so like the triac chips we tried, none of them were good enough for the motors in the vending machine.

• MOC3021 would work once and then fail closed, running the motor forever and smoking

• FOD420 did the same thing basically, although one of them worked a few times first

• TLP3023 never worked at all, probably because they're only rated for 100mA and died instantly

• not sure what part to try next
