When you ask a Hackaday crowd to design a business card, you should expect to be surprised by what you get. But still, we were surprised by the breadth of entries! Our judges wracked their brains to pick their top ten, and then we compared notes, and three projects rose to the top, but honestly the top ten could have all won. It was a tight field. But only three of the entries get to take home the $150 DigiKey gift certificates, so without further ado…
Blinkencard – Pocket Altair 8800
[ajlitt] built a full retrocomputer, and a slick looking one to boot, in the size of a business card. Of course, you could run an Altair 8800 emulator on your cell phone, but without the entry buttons and real-live blinkenlights, it just wouldn’t be the same. What our judges loved most about this build was the use of an FPGA and and ESP32, for IO and storage, the reverse-mounted front PCB that doubles as a faceplate, and of course the nice 3DP bezel that hides the bodge wires from view.
BetaBoard – Tiny Particle Physics Lab
So you might have thought someone would put a retrocomputer on a business card, but a working radiation detector was not on our radar. [Tim – DJ8TK]’s entry makes use of not one, but six BPW34 PIN photodiodes, which have the benefit of being well studied in the hacker radiation detection sce ..
