Description
Jam Electronic Timer (JET): Compact Edition
A version of the P8 Jam Timer (JETT) designed to have all electronics (except a single horn speaker) contained in the main enclosure.
Hardware has been simplified somewhat, but still uses the same Arduino firmware as its predecessor. The audio amplifier in the original has been replaced by a TDA3116D breakout board with minor modifications:
- Remove and short C9
- Remove and short C10
- Connect Left Input to GND (performed on the PCB)
- Replace R2 with 75K
- Replace R3 with 47K
- Remove R1
