#189852 - PIC12F629 Responding to: ???'s previous message |
Priced at 0.7$ a piece I did interesting project with it yesterday, I converted a 3 phase air conditioning control unit to work for single phase. I removed the opto-couplers and made this chip generate 3 phase signals synchronized to the zero crossing detector of the single phase. then fed these signals to the main controller. It thought that 3 phase is available and customer used it to control a single phase compressor.
It was fun and I earned few bucks. See photo here: https://plus.goog...9187477482 Mahmood |
