We have three boys so there is lots of Lego in the house and lots of technology. I got fed up of four way extensions trailing everywhere with mismatched USB-mains plugs. So I thought I'd build a dock with a dedicated charger and something like a toast rack to hold all the tablets and phones. I thought I'd prototype it in Lego before committing more resources to it. After a few iterations it worked so well I kept it in Lego. It also means the boys are happy working with it.
Grahamwithimps made it!
