I had used codex to reverse engineer an electric skateboard to unbrick it. It was a bit more involved because it required soldering wires directly to the UART headers in a very awkward location.

Took about 10 hours and it now works fine. Without codex, this would have taken me significantly more weekends having little experience with skateboard firmware.

This is giving me the confidence to RE my cat feeder. The company (Petlibro) has an outage and now my chilled wet feeder that should be a dumb, offline feeder is basically bricked now.

The device reports fine wifi but the backing services are totally busted.

Why do you have a cat when you can't be bothered to feed it yourself?

		You're making some assumptions. Weird question anyway. Why eat food at all if you can't be bothered to farm it yourself.

I have one of their dry food ones and no longer need it. Sad story, but it happens.

My cat scarfed and barfed periodically, and I always wanted the Petlibro (the simple one) to slow feed by incrementally turning the auger, just to see if it helped. I might dig it out and try my hand at this.
