And then, one of our neighbors bought a new garage door fob, flipped the DIP switches into the right configuration, and couldn’t figure out why it wouldn’t open the garage door. Knock knock knock. It was the garage door opener that triggered me to think about how normal people would handle any of these situations. Normal people don’t have a soldering setup just sitting around ready to get hot 24/7, or a scope to diagnose a garage door RF transmitter at the drop of a hat. How do the normal people survive?
