Lets see if YouTube demonetise this one. Previous vape device teardowns have been put on restricted advertising because of their subject material, even though they were technical videos.

These work, but could do with a bit of improvement. They do have scope as a project case for your own design though.

This must be the first time I've seen a 1V microcontroller implemented in this style.
This very common and totally mass produced air freshener (!) unit is a piece of art inside.
I wondered how this linear 36W lamp was achieving such a good power factor (0.95).
It turns out that it's using a driver styled as the front end of a power factor corrected supply that charge...

If you didn't receive a message about them then it's not too late as I will be randomly sending out some more, and probably other PCBs too.
This battery was sent by Kim Sleep a while ago. I should have made this video sooner, because it's actually quite nice inside.
After a human review of my public service video on the UVLEN scam it was decided to make the video unsuited for most advertisers as it fell into the category of:-
Focus on accidents, pranks ...
Since the video is intended as a PSA for an upcoming release of a shady device, I'll be releasing this video early.

There's economy and there's economy. This crappy product took it a bit too far.

This video is basically a warning to people who may get duped by this very suspicious product. Judge for yourself....

I really wasn't expecting this cheap power monitor plug to have quite such a sophisticated energy monitoring chip in it. That one chip has a manual over 100 pages long.
Possibly my worst abuse of 3D printing yet.

I bought this little rechargeable fridge ozone generator with low expectations. It turns out to be sensibly designed and pretty good, although it could use a slight software tweak to double i...

On one hand this seems like a good idea, but on the other hand it might turn the chat into a space rocket.

I'll be joining the guys on the HVAC overtime channel for a live stream tonight (actually 2.05am for me).

This version of the PCB has the option of using through hole resistors (quarter watt) or 1206 surface mount ones. The PCB and LED spacing are the same, so it will fit into a standard 6" by 4"...

This modification is really not recommended. The unit is very sophisticated inside and seems to incorporate voltage regulation for the high voltage circuitry.

I was sceptical about this device because it's not something I had come across before and had very strong similarities to a previous quack water hydrogenator.
For those who like the live streams, this Saturday's stream is ready to go.

Does anyone have a pinout for this module before I take it apart? I've had a quick probe on the three pin connector with a meter, and think I've got the common/negative sussed, but there are ...

There's probably a reason nobody has made an ultraviolet moonflower disco light. But that's not going to stop me giving it a go.
I'll be trying this stream on a different setup to try and resolve the audio issue that only seemed to affect some viewers.

This video was originally going to be a guide to identifying real and fake germicidal lamps, but I chopped the first bit because it was combining a PSA style video with a technical one.
Not the normal type of video for this channel, but I thought I'd record it for variety.
In hindsight I should have considered including both through-hole and surface mount resistor options on the original design.
It's clear that many still prefer through-hole components (and i d...

In hindsight I think I should make a video showing how to make a safe charger for products like this.
