Total teardown of a flexible LED filament lamp.
Added 2017-04-05 16:08:29 +0000 UTCThis was a very destructive video that took a surprisingly long time to make. I had a thoroughly enjoyable time reverse engineering this lamps relatively simple driver with an odd twist that is probably intended to make it dimmer-compatible by providing a continuous low current load for the whole mains cycle. The LED filament construction is also completely new with the ability to accommodate series/parallel arrays of chips. That means it's actually viable to make a 12V version of this lamp. At the moment the first ones only seem to be available for 220v to 240v use.

Have you thought about a wrist strap for connecting to earth on the quick test? Could be invigorating.
2017-04-06 03:50:41 +0000 UTCI picked one up surplus from a lab supply company in Florida. It seemed to have never been used, as it had no cord and the colors are UK. I only got it because I saw Clive's - I don't think they are common in the US - but it's been terrific. My favorite use so far was to temporarily use my circuits while wiring up my remodeled family room.

2017-04-05 20:26:28 +0000 UTCI picked up one of the QuickTest boxes with US colors. I put it on the bench, unsure of when I'd actually need it. Turned out to be about two hours later when I wanted to do a quick hook-up of a laser power supply.
