The twin challenges of the pandemic and now the semiconductor shortage have been particularly hard on the designers of event badges, as events have been cancelled and uncertain supply issues render their task impossible. When an event goes virtual, how do you even start to produce a badge for it? Make the badge and rely on enough stalwarts buying one? Or maybe produce a badge that’s a fancy take on a prototyping board?
For Hackaday Remoticon 2021, [Thomas Flummer] has produced a novel take on the second option by distributing a badge as a set of KiCAD files that can either be ordered from a PCB fab as a prototyping board or used as the canvas for a PCB to use whatever components are to hand. To demonstrate this, he’s produced an example badge that’s a MicroMod carrier.
So if you’d like to chase the full Remoticon experience with a badge there should still be enough time to order a set of boards, but to design your own electronics you’ll need to get a move on. What you might build upon it is up to you, but if you have an ESP32 module lying around you might wish to consider cloning the SHA2017 badge or its successors with the badge.team platform.
