4" Seven Segment LED Display

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!
