The TwitALU as a display piece

The TwitALU has gained massive interest from it’s exposure on several technology blogs including the famed Hackaday.com. It has also been well received on it’s outings to the DigiMakers Raspbery Pi boot-camp events at @Bristol.

Members of the Electronic and Electrical Engineering department will be glad to hear that the TwitALU is finally being mounted on a wall in the Merchant Venturer’s Building and will soon be up and running for all to play with :). See if you can work out where it is!
