An LED Persistance Of Vision Name Badge
I have seen the Defcon badges, and thought they were cool. Why cant my kids have one as well – but specially built for them?
So here you go – A simple badge that uses a PIC 16F88, and a handful of LEDs, and flashes your child’s name in lights when they shake it, or push a button.
I have left space on the PCB that I designed so that it can support an accelerometer. It isn’t in this version because I have to order the parts. This one is created using the bits I had in the garage!

You could download my PCB file, but it probably wont work unless your child is named Sian! Just in case people ask, I have included it as a PDF file.
In Sians case, I created a PCB layout – and made a decorative fill as a background – I think it turned out pretty well!
Here is a photo of Caties board having finished the etching process – I just have to clean the etch resist off the board, and mount the components.
