4" Seven Segment LED Display
Description
This Is A Large 4" Diagonal To Diagonal 7 Segment Display. It Uses 20 5Mm Led'S And The Colours Are Completely Your Choice. In My Version, I Built It With 20 Bi-Coloured (Red And Green) Led'S Which Had A Diffused Lens. This Is Great To Use On Walls And Makes An Awesome Clock, Temperature Monitor Or Maybe Use It To Display The Number Of Unread Emails In Your Inbox!
