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.
