I am looking for something very closed to this project. The device would be elapsed time counter for the oil burner. On/off signal is available from the oil burner (230V on/off. Accumulated time elapsed on display and also reported to the serial port of PC. Reset button is a must. Meanwhile the computer is off, the unit is working and collecting the time data.
This would give an idea just how long the burner has been on and therefor how much oil has been burned.
I do not mind to help on design of the printed circuit board. |Delete 'P-' before: '' but after: '
