After needing a new scoreboard for their local softball team, Instructables user "boscopsoultrane" decided to make an electronic version at a much lower cost than those produced commercially. To create digits that can be viewed from a distance, an interesting approach has been used - the recreation of seven-segment numeric displays with LED strips used for each segment. Doing so gives a bright result, that easily lends itself to Arduino control via some MOSFETs. Furthermore the scoreboard can be controlled with an infra-red remote control - again, easily done with Arduino.
This is a great project that can be adapted to almost any sport or display requirement, and is fully documented so you can follow along and make your own. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
