What considerations to observe ? Need 1 Hz, sharkfin waveform charging/ discharging oscillator.
3.3V supply, around 100mA load solenoid to move a lever...
A 7555 timer could work on low voltage, and has a pin with the proper waveform; perhaps driving a transistor to feed the solenoid.
Anything I should be aware of ? Needs to be highly reliable.
