1. Please take a COVID self-test beforehand. Cases are soaring and we don't want to spoil any holiday plans (including our own). :)
2. If you are bringing a laptop for flashing, try setting up our autoflasher. Cloning & running the image builder takes a long time, but you can definitely try:
- installing the udev rules
- running esptool
- running the included picotool binary github.com/badgeteam/mch2…
3. Collect your USB-A -> USB-C cables, just in case. We should get a fresh shipment in before the weekend, but if that gets delayed we like to have a backup. We'll let you know when they arrive. :)

To summarise past few weeks into a single thread about the MCH2021 badge with everything we have done so far: (a very long thread ;) )
We have already secured sponsorship from three very cool companies, namely @EspressifSystem , @latticesemi and @BoschMEMS . Lets see what they are bringing to the project:
From @EspressifSystem we're receiving the ESP32 Wrover with 8mb RAM and 16mb Flash! Its the latest version of our dear friend the ESP32. We're also getting a SECOND PSRAM chip for the FPGA part of the badge. Espressif, thank you for supporting us!
Picture thread! We had a massive sweatshop yesterday because we messed up the design and had to rework 350 badges for @HotelHacker . A story in a bunch of pictures. All shots by Noor, our newest badge.team member and proud owner of an actual camera!
First step was cutting off 350 x 5 mosfets. Since we reversed the LEDs by accident, sinking to GND wouldn't work. We cut the mosfets, as this was doable without training and a lot faster than using hot air. Some traces were damaged (1% of the boards) but those were fixed easily!
A side project was prepping the battery boxes for next week. The leads were long and sharp, so we trimmed them down. People had to wear eye-protection, these pins were really on the attack! 700x 2 pins were cut. Bandaids for the blisters from the cutting were handed out.
