I tried to post this earlier and never saw it on the list.
I'm kicking around the idea of controlling an ordinary 120 VAC
incandescent light (actually a 150W heater).
I'd like to control the heater based on the temperature of the surface
beneath it. I need to control it to approximately 105 deg F (more or
less; great accuracy is not needed here.)
I've found some basic PIC circuits on the web but I wonder if anyone
here has any suggestions, both for the temp probe and for the heater
control.
As this will most likely be a one-off, an inexpensive commercial
solution would be fine.
(Aside: anyone on the list do small one off jobs?)
