I've been thinking about ways to get signals into and out of a computer without too much fuss. My soldering skills are average, but when it comes to complicated projects I prefer to buy them pre-made. Trying to locate parts to make some of the interfaces found on the internet is next to impossible living in the UK on a tight budget.

I have launched this site with some of my own projects in various states of completion.
If you have a project or idea that you would like added then make a suggestion.
