Now you can troubleshoot. If there is a short, the light will limit the fault current.


I actually have wanted to make one of those for a while. Maybe this is
the right time. I like the dual outlet idea. That way, I can plug in
different power bulbs depending on the type of device.

Also beware using a scope that the ground in your circuit may be live.


I recently got myself a differential probe.

I would buy or make an isolation transformer as well for your safety.


That is also on my to-do list.

Replace the FET and cap and turn it on with the 60Watt bulb in series.


Transistor and capacitor set are on order.
