Belgian maker Frederick Vandenbosch wanted a wearable to take to this year’s Raspberry Pi Big Birthday Weekend (Pi Party). So, he put together a Raspberry Pi Zero, a Pi Supply PaPiRus e-paper HAT, a Pimoroni Zero LiPo and a 3D-printed back plate and created a lanyard-hung badge. The badge shows his personal details, his logo and also photographs of various projects so he could press a button and then talk about the project being shown. He’s written the whole thing up on the Element 14 website, so head over there to take a look.
