In the wet, winter days when welding a van just isn’t practical, I’ve been looking at ways to occupy my time.

This is my current hobby.

It’s by no means finished.  It needs an entire recode before I test it on a vehicle.  It runs from a USB supply (from the 12V socket) and you can select the message you want displayed using my custom Android app.

The plan is to have it suction-cupped to the rear window in the van, to provide some sound advice to drivers who should probably overtake me rather than wait behind me!

I’m considering attaching another matrix to the side so I can fit longer messages in (or even just to make the current messages easier to display).

Thoughts?
