Converting the lightning detector over to RS-485
During the precessing of getting the RS-232 communication working with the lightning detector and my Linux box, I learned the advantages of RS-485. RS-232 sends over its signals as a single ended voltage. RS-485 uses a differential signal. This has … Continue reading

Solution to reboot issue?
Could it be that I found the reason that my lightning detector rebooted on strong sparks? When I ran the project without the programming cable connected I stopped getting resets. Connected it would reboot. Perhaps some kind of ground loop … Continue reading
