I was asked to help make a badge for next year's DEFCON in Las Vegas. The group is focused on biohacking, but we are not the folks making the Biohacking Village's badge.

We spent a lot of time trying to design a badge that would look appealing but add a function the users might enjoy after the con was over. We decided on a heart rate monitor. I picked a popular sensor with plenty of support and libraries so we would not over-extend ourselves. The MAX30105 board from Sparkfun had an illustrated guide, and there was a module on Amazon with fast shipping.

For a processor, I selected an ESP-WROOM-32 since I wanted to learn more about them, and I had a demo board in my stock.

Enough background
The first step in the badge-making process would be to make a prototype with functional hardware, in any form. In this case, all the necessary pins for a Hornbill demo had headers installed. A MAX30105 module was also outfitted with header pins, and the two were connected on a solderless breadboard. This will be the minimum hardware for making a pulse sensor.

No program could be sent to the controller due to driver issues. The next step will have to be getting the module to communicate and accept programming.
