But cost lots more than this project is worth (for me!)

Indeed

For me - bothering with the computer - because I can. Also most capillairy tube
thermostats are utterly rubbish - when I replced the element in this oven I think
I must have damaged the thermostat too as it also stopped working - the replacement
is 15C cooler than the original one. It's also part of my master plan to automate all
my ovens, mixers, etc. building a dough proofer/retarder too... Geek in a bakehouse!

	Ah well in that case have some fun - pick your switching device(s)
and connect as thinly as possible to an output pin(s), also feed
transformed, and heavily clipped (ie. as near to square as possible) mains
into another for an edge triggered interrupt to act as a zero cross
detector. Write some fun sweet software. If you're going to have a computer
you might as well minimise the extra hardware and do as much as possible in
software.

I finally got round to doing a little blog post in this:
