Quite an interesting little device. Mainly intended for 220V to 240V use.

Truly one of the weirdest designs I've come across. It works, but I'm not sure those little red LEDs are rated for the current that could be going through them.

I've seen these kits on eBay for a while, so it was inevitable that I'd have to try one out.

I got one of these a while ago, but never got round to making a video about it. Then I decided to buy another to see if they had changed much and at the same time Michal from Poland sent one in a package of stuff. So here's a look at the insides and circuitry of three different selfie li...

This is a project that started as a simple rough project for testing the dry photosensitive film used for making your own PCBs. Then it turned into a very neat little project with an equally neat PCB.

It appears that a few people have had issues with the operation of the Hakko style soldering stations, particularly the digital ones. Here's how to apply a fix that should solve a lot of the problems.

I don't mind giving what appears to be a genuinely charitable organisation a bump every so often, so here's a video about a solar light designed for areas of the world with lots of sun, but no electrical network.

A nice laid-back video featuring a set of LED lights from eBay that seem to have been replaced by the common copper-wire type.
I made this video while the lithium jump start pack was getting ready for its moment of fame.

The old time switches are really quite intriguing in their operation.

It's a while since I've bought one of these common little lights. Many of them have a cosmetic solar cell and non rechargeable battery. Is this one going to be real or fake? Place your bets now.

Poundland (A UK dollar store) has been adding a lot of really good LED lighting to their seasonal ranges, and the latest release is the summer lighting. It's very good stuff.
