Reprap Heated Bed Testing

 This is the heated printbed from Iain's reprap being tested after he'd replaced the nichrome wire based heater with some chunky high powered resistors:

Once all soldered together and attached to the build platform with metalised epoxy, we fired it up and checked it out with a thermal imaging camera graciously loaned by my work:

Interestingly, the parts where there isn't any Kapton tape show up as much cooler - not because they are any cooler but because the bare metal is reflecting an IR image of the cold window. Anyway, the heater seems to work pretty well as Iain's reprap is churning out all sorts of interesting stuff.
