I bought a dirt cheap toaster oven to convert to a solder reflow station, and I noticed in the teardown that it apparently has a neon power indicator. It goes out instantly when it loses power instead of fading like an incandescent, and it measures open-circuit when off.
I'm not opposed to cutting it out of circuit, but I also thought it might be nice to have a rough indicator of what it's actually doing, if it actually works that way.
Here's the circuit:
- Does it "just work" and produce an incandescent-like end result?
- Can it confuse the triac? (probably not because it's in parallel with the resistive heater and my software is going to hold the opto on anyway)
- Is there something else I ought to know about using neons and triac dimmers together?
