I made a RGB LEDS as simhub software with low cost taking advantage of a 3 1/4 "drive cover.
I'll use it in my 2dof simulator I'm making.
2 RGB Leds card
50cm microphone wire
Old computer plate of 3 1/2" drive
Using the front cover of a 3 1/2" drive from an old enclosure:
Two RGB LEDS cards will be installed behind the cover:
Using a crepe tape we mark the points where the holes will be made:
Finish using a sandpaper and a small drill to make sure the two plates fit snugly:
Ready now the finish:
So easy and very, very low cost!
