Does anybody where i can fin an already made led ring like this:http://farm3.static.flickr.com/2071/2659703029_df25a369e7.jpg?v=0
another solution is to design the ring in eagle .brd and using 3mm led, but i am very lazy 
Julien,
This is a custom design and i use SMT leds for this. The Eagle PCB is 90% done. I had to stop working on it because of my healt issues last summer. I going to resume my activities this month.
