Seven segment LED displays usually come in single color like red, green, blue or yellow. But probably there isn't any RGB displays in a market yet. After this mod situation can change.Markusdecided to fill this gap and made one by himself. All he did is took a an existing 7-segment display and removed single colored LEDs with dremel and replaced them with SMD RGB LEDs.
SMD LEDs already were with magnet wires that made the process easier. Obviously the number of pins tripled so additional socked was needed. He made a simple board with all pins and glued a display to it. Great inspirational work. isn't it?
