A non-bike related fettle here...
While cooking dinner t'other day, the oven element started making all kinds of interesting BZZZEEEEERT-y noises, combined with flashing lights and cessation of heat output.
I had to finish the roasties off in a frying pan...
Anyhoo, got the offending element out.

Here's a close-up of the busted bit.

The resistance wire inside failed and then arced for a bit. That's what blew the hole in the side, letting the smoke out. Electronics and electrics all work on smoke, and when there's a hole, the magic smoke escapes and they stop working (may not actually be true).
Just need to wait for a replacement element now...
