Subject: Re: How not to control ovens - was - The list is huge! Really huge!

Has anyone actually read the recent (January) Elektor article on the
SMD oven? It uses a K-type thermocouple talking to a MAX6675.

The program in the AT8952 calibrates autmagically and then compensates
for over and undershoot. Has an LCD display etc etc etc.

The CPU is available from Elektor ready programmed for about £12. The
code is available for free download from their site.

I'm not in favour of totally slavishly following published designs but
in this case all of the hard work has been done leaving the usual
personal customisation.

Before someone asks, I don't have shares in Elektor and I do think
that lots of their designs are way overcomplex.

Here in Ireland, local supply of components is always a problem but
between Mouser in the US and RS and Maplin locally we can usually get
what we need.

Elephants was deliberate ;-)
