Create a simple electronic timer
Budget: $30 – $250 USD
This must be pure hardware and not software like rbpi,
Must be very small and cheap.
I need to connect a wire to ground for 3 seconds every 24 hours,
Accuracy is not very important, can be between 23 and 25 hours if needed.
Seems like this can be done by a 555 IC but this would need a large capacitor, I need something which is even more simple and preferable smaller.
