I made this a long time ago now. It all came about because LED’s are so popular and so cheap in Taiwan I just thought I would make something with them. As you can see it is very small, I used matchsticks for the base and a lovely japanese style for the cube. I wanted a switch so I just soldered everything onto some stripboard. It looks beautiful at night with a lovely warm glow.
