Sewing my Hondahack components together to make Don't Break My Heart
My hack: a wearable proximity sensor, which allows traffic travelling behind cyclists to see via pulsating red/amber/green pulsating heart if they're travelling to close to the cyclist. I had to hurry to finish the functionality, so it's not so pretty - but I'm going to tidy it up. All told I made it in a evening and an afternoon, so that's not long to design, code and build an electronic wearable!
