Enhancing a Magnifying Headband with Auto Sensing Light -- Episode 585

Do you often use a illuminated magnification headband? Do you get annoyed that you need to turn it off and on when looking away from your work? This project contains 2 solutions, a basic tilt sensor option that can be added in minutes, and a more complex distance detecting circuit which will change the illumination depending on how far away the object you are looking at is.

Thanks, it hard to find the culprit further than "something under the epoxy blob", by bypassing the switch circuit which has the auto power off and other stuff hidden under expoxy, the problem is resolved…

So this is wired after the headset on/off switch? How about wiring it before the headset on/off switch and just add a new switch.

Yes, that seems to fix the issue. I was hoping to keep the original switch, but changing it definitely helps, probably because it then bypasses the circuit under the epoxy blob. Downsides to this is there is no auto power off, although I guess I could add it again.
