I've been working on a reflow oven
(and hijacking other people's threads to boot)
so now decided to have my very own bragging thread
started with a 1 kW 9litre toaster oven
4 heating elements; 2 top 2 bottom
I added a K type thermocouple
(actually took a couple of goes as the ifrst one melted!)
I took it apart, cut off the smouldering ends, joined the new ends together
used heat resistant (fibre glass?) insulation this time
disconnected all the oven control gear and wired it via a triac
triac controlled by 'duino of course
software attempts to match the profile for reflow ovens
anyway - time for some pictures
here's the triac driver board
it's inside the oven to keep mains voltage well away from small children and idiots
(er and me
2nd picture shows the much reduced internal wiring
3rd picture shows the first board "wot I made"
it's a micro 'duino
once Nick Gammon helped me with the bootloader - it worked!
4th picture is part of a range of camera kit we're selling
all the SMD parts sorted in < 10 minutes!
