Ambient explore and hack of a recent eBay charger

This looks very similar to a charger I looked at 5 years ago, but the circuitry is better.

It would make an excellent cell holding case for a custom charge system.  In this instance I ju...

Neat little Sansi PIR light

Having been impressed by the Sansi ceramic core LED lamps, I thought I'd take a look at one of their other products.

It seems to be quite well designed too, with a logical layout, and some ne...

TikTok grade IKEA charger video

And for the youngsters - here's the sub 1 minute version that still manages to cram in most of the important bits.

Making shorts that contain useful technical data is extremely difficult. &nb...

IKEA charger - the shorter 2 minute version.

Because the main video went into so much depth on this complex charger, I decided to make a much shorter (2:20) version for those in a hurry.

It covers the main points, but doesn't go into to...

Excellent new IKEA USB charger

Thanks to John for sending me some of these units.  I expected them to be well built and they lived up to my expectations and then exceeded them with some really novel extra features.

Inside the Guinness clip-on nitrosurger

A device that uses ultrasonic energy to cause cavitation of the nitrogen in Guinness in a controlled manner as you pour it from a can.

The Volkslicht "people's light"

An interesting light that was sent for our exploration by Kai Steffen.

It's a bluetooth controlled light that was supposed to be the new standard for lighting in Germany, but didn't quite cat...

Chunky high power keychain light

I'll make a guess that this is a clone of another product, but there are so many copies of specific styles that it's hard to work out which came first.

It's rechargeable by USB C and has a 50...

Very crap UV floodlight

I'm sure I've made a video about the white version of one of these lights, but a quick search didn't find it.   I wasn't even going to make a video about this one, since it was going to b...

Intriguing solar light with interesting chip

I think this is the first time I've come across this particular chip (YX8183).

It is designed for solar lights that use a lithium cell, either standard or LiFePO4, and has built in LED curren...

Slightly shonky voltage probe

I promise, this is the last vehicular themed video for a while.

It's a low voltage probe with built in digital voltage meter, that could be used for many applications and not just automotive....

As promised in the live stream...

Here's the video about the mechanics version of a logic probe.

It can indicate polarity of 12V circuits, and forcibly change their state with internal short circuit protection and warning. 2023-03-23 23:41:05 +0000 UTC View Post

The first section of this video is identical, but there are two new sections with more detail including the use of an oscilloscope to confirm that the unit is indeed switching voltages.

Another carbonation experiment

Having already done some fuel injection experiments, I decided to do a carbon dioxide one too.

I'll let you judge the results yourself, but suffice to say that I've already consumed several g...

Fuel injector test unit with weird circuitry

I'm not sure if there are multiple variants of this unit or if it's just another stolen design with legacy circuitry and software.

The software is terrible.  Really basic, and the only w...

Inside an NVR (No Volt Relay)

This is a very common component found on industrial equipment.

As well as acting as an on/off switch, it has the extra safety feature of latching magnetically, so that in the event of power f...

Intriguing USB powered UVC "steriliser"

This is one of many products that popped up during the pandemic to cash in on the craze for sterilising groceries and other things.

Flux residue and fairground games

I filmed this while travelling (and quiet tired) so it will sound and look different.

The video looks at some PCBs from almost thirty years ago to see if the flux residue left on the PCB had ...
