Electronic LED Badges? We don't sell them here at Alond

But we did find a place that does;

https://www.tindie.com/browse/electronic-badges/

There are simple badges you can solder yourself, some very well styled badges, simple led back-lit conference badges, a "super" badge that you can fully program and has a camera and an OLED display.

Others are available that allow you to program them musically, and my favourite;
K.I.T.T. Knight Rider Blinky LED Badge
