I'm aware I've been making too many videos on this subject recently, but this one had to be made due to the tackiness of the lamp and it's astonishing 50V LEDs.

I've been playing with the thumbnail text. The novelty will probably soon wear off.
One day I'll just make a single video about dielectric barrier discharge ozone generation, and that way I can link to it from videos like this.
At the moment I repeat a lot of the same informatio...

It's a shame they have designed the unit to fit into the sm...

It does actually have circuitry besides the potentiometer.

By popular request, a self powering switch that generates the power to send an RF code to a receiver when toggled.
This was REALLY interesting.

I was expecting this to be more complicated than it was. But it does still contain some interesting electronics with fairly good design.

Those of you who watch the weekend live streams will have seen the prototypes of these lamp covers. They are designed to fit in place of the original globes on cheap LED lamps to turn them into large illuminated crystals.
Having already reverse engineered the four-wire version of this, I thought it would be fun to look at the simpler two wire version.
I love the visual effect of the tubes in these, but the...

It's a while since I've been in London, but last time I was there this little lotus light caught my interest. Mainly because I was in the Chinatown section of London, and it seemed appropriate.

And now for something completely non electronic.
Simple, but also quite complex. And apparently causing issues with a tendency not to seal fully and waste water.

Finally caught up with sleep, and decided to make another custom lamp.
I think I may have been a bit under the weather last week. It's always hard to tell when you live on your own, until afterwards when you feel better and realise something was wrong.
I was struggling to stay awake when I made this video due to a few restless nights leading to sleep deprivation. Does it show in the video?
Should I at least re-record the second pa...
