I thought this was going to be fake
This unusually cheap kinetic powered remote switch has the absolute simplest power generator in it yet.

2021-04-05 01:28:36 +0000 UTC View PostSorry. It's another dooby themed video
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.
Unusual sauna sterilisation device
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 w...

The software in the little microcontroller is what makes this unit really special. But the electronic design is good too.

By popular request, a self powering switch that generates the power to send an RF code to a receiver when toggled.
2021-03-23 18:07:49 +0000 UTC View PostHotel key-card power switch
I was expecting this to be more complicated than it was. But it does still contain some interesting electronics with fairly good design.
Fixing the supercomputer
Not sure if this is a good video or not, but it's swapping the LEDs that had failed for red ones to show the status of crappy Chinese LEDs.
The triple script crystal lamp project
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 in...

Having already reverse engineered the four-wire version of this, I thought it would be fun to look at the simpler two wire version.
