BTW, about weller irons..
I got an EC2001 soldering iron without the base. I had one of that in
the past and it has a transformer, a circuit board and a (E X P E N S I V E)
exar IC that controls the temperature. Of course, I can do better and use
pwm, a mosfet and a microcontroller to drive this iron, but I know nothing
about the thermistor temperature curve. Maybe someone can help? If I could
at least know the resistance of the thermistor at 100, 200 and 300 degrees,
I'd be more than happy :) And create a new open source project :)

Sorry for psoting this publically, but a private reply
to Rob got a
bounce 'due to unacceptable content'. OK, I probalby wouldn't talk about
soldering iron bits in polite compnay, but I cna think of many worse
words to use :-)

Hello
Tony,
If you recall I got a Weller TCP probably just like yours. I have a
couple
of PT-AA8 tips, but they seem a bit too big for working with some of
the
boards I need to work with.
What tips would you recommend for working with the H7140 PSU (and the
RD53
motor control board)?
Well I use a PT-AA8 for just about everything. There is a finer one
(PT-O8???) which I use for some SMD work (but a lot of that gets done
with the PT-AA8 actually).
Certainly it should be OK for the PSU and RD53 boards.
