Hi I'm Stuart... welcome to my website. I've been an electronics service engineer for most of my life, repairing Television, Audio and Computer equipment for the domestic market. This site was originally started as a place where I logged the various faults I'd found with their symptoms and cures, but as I no longer work in this field, I'm unable to keep the repair pages up to date. I still keep them available though for anyone who is interested

The site is now a place where I post projects and guides, and my wish is that it will steadily grow and get better with time. When I read a web page I like to 'cut to the chase' and not have to wade through loads of text to find what I'm looking for, and I guess others are the same. So the pages here are minimalist in style, but hopefully, still convey lots of information

"I've always liked to build things and a notepad and pencil are always to hand for when an idea strikes. Not everything makes it off the paper, but it's fun to just scribble, create and learn"... More >>>

Please note that a few of my older projects have used components supplied by Maplin who have now unfortunately ceased trading. This shouldn't be a problem though as I've always used readily available parts. My favourite UK electronic component suppliers are:

eBay (of course!)
Switch Electronics (also known as led-essential on eBay)
Spiratronics (also spiratronics on eBay)
