To answer Fredrik's comment about the zero ohm link, here's a look inside one.
It's made like a traditional resistor that would use two end caps on a carbon coated cylinder, but instead uses a solid copper cylinder.

This video also uncovered an unexpected Samsung glitch. All phones stop and restart recording after about 30 minutes at 1080P due to file size requirements. In this instance the Samsung also decided to refocus to a random position without warning when it restarted.

Thus is a neat lamp. Not just in its appearance, but also the circuitry.
I'm not sure if it's available in a 120V version. Theoretically they could use the same high voltage filament (265V) with a voltage multiplier to drive it from 120V. Or they could just use a different version of the filament...

I'm not sure I've actually ever seen one of these in use, but thought I'd get some for us to take a look at.
It's quite a clever design in the way it's been implemented with some existing parts.
2019-10-17 03:52:27 +0000 UTC View PostI'll soon be doing a build of the Department of Villainy PCB and since it will probably be a full build I was wondering if you guys had any questions you wanted to ask. You can ask questions about anything at all, and I'll try and answer as many as possible in amongst the normal build commentary.

This video was a full version that was thwarted by a glitch on the Samsung S6 I was testing to see if I might choose a more recent model to record with. Something went wrong resulting in a pause in the recording turning into a static frame with audio, followed by the rest of the video after the audio had finished.
Poundland (Dealz on the Isle of Man) has these interesting units for £5 at the moment. If you slip a suitable Amazon Echo device into them they allow it to be used as a portable device with power coming from a 10,000mAh rechargeable cell.
