Looking at my steampunk keyboard, it looked quite plain to me. So I decided to add a keyboard illumination. (For further information look for "keyboard LED"
on this site)
Some brainstorming over a glass of $5 wine (can something good come from that???) and I had an idea how to accomplish this.
As you can see, I attached an arm to the connecting pipe which contains 2 bright LED's (13.000 mcd) hooked up to the 5V supply of the key board. (LED calculator)
In hindsight I would attach a street 45 degree fitting directly to the T (it would fold nicer)
