When my compressor starts and I'm working in my garage it make me jump out of my skin every time. I need something to warn me of its imminent start.
So could someone out there give me some clues as to how I might do the following:
Build something which beeps for 3 seconds before switching on a 1500W compressor motor. It is to be activated by the pressure stat on the unit closing and of course must turn off the motor when it opens. So, to summarise events:
- Stat. closes
- Beeper sounds 3 sec.
- Beeper stops. 240v supplied to pump
No heart attack
- Stat. opens when at pressure
- Pump disconnected
I am quite competent and could translate a circuit into a working unit without problems but I wouldn't know where to start designing it.
Many thanks.
Keith
