I'm on a roll today with many experiments and two build videos.

Here's the second build video, showing the construction of a supercomputer lamp, using a classic eBay/AliExpress lamp kit with some customisation.

Supercomputer light bulb build - with schematic

This project is definitely only suited to experimenters with suitable mains voltage experience, as it involves high voltages. It's the classic retro spaceship supercomputer effect, but in a convenient light bulb format. Because the flashing LEDs go almost open circuit while unlit, the panel does need one standard LED in each parallel group to clamp the voltage to a safe level for the flashing LED. I used the hard to get 0.5Hz LEDs here, but it will still look good with classic 1Hz ones. Diffused LEDs give the most pleasant appearance. I modified the capacitive dropper drive circuit to run at much lower power to give a more visual effect, since it doesn't need to light a room. You could also use the slow RGB colour changing LEDs, as they seem to work OK in series circuits. The lamp kits are available from AliExpress and sometimes from eBay, either with or without LEDs. They actually work out more expensive than fully built lamps from some sellers. You can get a range of sizes. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators

Dang! That's kind of fun. Thanks Big Clive! What a cool little build and project. I wonder how it looks in a room say from the ceiling or something.
