This is just a short extra video where I reverse engineered an LED lamp with a new style of current regulator chip.
Thanks to Ron in the Netherlands for taking and sending the picture. 2021-05-10 01:16:49 +0000 UTC View Post

Some may think this is a thinly disguised ioniser build.
But it's a little history lesson too. Alexander Chizhevsky was building ionisers before I was even born.

A neat little LED ornament with non standard LED neon strip.

Slight sleep deprivation at the moment if I sound a bit tired in the video.

I clearly have no scruples.
But to be fair - distilling Jagermeister did yield interesting results.

I wanted to see how they had constructed the AC LED filaments in the small festoon lights.
The LED array is quite unusual.

You see that little resistor in the video thumbnail? That's the bit that seems to fail on these unusual little lamps.
The lamps are commonly used on strings of festoon cable, and it...

The single most frustrating thing about this teardown is that I hovered over the two screws through the LED panel before deciding to leave them in place. It turned out that the heatsink plate would have come out easily if I had removed them.

The pleated filter is roughly eq...

Not as sophisticated as it sounds, but still provides a nice warm wash of light on a wall.
Quite hackable if you want something different.

The Blackview phone has a very sensitive Sony camera chip that can see faint corona discharge.
This is a module out of a Sharp Plasmacluster unit which applies a positive and negative voltage to needles in front of metal rings of the opposite polarity. It's interesting to see that the po...
This makes a change from the small 12V batteries. The range was also good and the standby current unmeasurable at less than a microamp.
But opening this switch to change the battery...

The idea for this video happened during a recent live stream, so since it involved whisky, I thought I'd get the Disney hat on and spoof my brother Ralfy's whisky channel.

This turned out a lot more complex than I was expecting. It isn't just operating as a simple timer, but more as a time accumulator which also responds to the defrost termination thermostat.
