Using a plug-in night light, a double-gang electrical box, a cover plate
with switch cutout on one side and a two hole receptable opening on the
other side, and a household light dimmer switch with push on/off, I
built a controller for my soldering iron for use when working on my 88
GL (vanagon content -[;<)> ! and other projects.

With the iron plugged into one part of the receptacle and the night
light plugged into the other, turning the dimmer switch varies the
voltage, adjusting the temperature of the iron. The light dims or
brightens accordingly.

Problem: There is no way to get a precise temperature setting, because
at best, with only light dimming to indicate hotness, it's a bit of a
guess.

Question: Does anyone have a suggestion as to some type of counter that
can be installed/used instead of a light?

Any input would be appreciated.
