About

We want to make an awesome badge.

We have an irc channel at #sha2017-badge on freenode and a mailing list at badge@lists.sha2017.org

Current team members:

  • realitygaps
  • the_JinX
  • Kartoffel
  • puckipedia
  • Underhand
  • Sprite_TM
  • MarkusBec

Our current plans and meeting notes are at https://pad.sha2017.org/p/badge.

We will continue having meetings online on the irc channel once every couple of weeks for the moment.

Badge functions

The idea is that everyone gets a badge that is primarily useful during the event, and also fun and easy to tinker with. The badge will be able to display information like a talk schedule, fahrplan, angel shifts.

In list form:

  • Provide information during the event
  • Talk schedule + fahrplan
  • Angel shift information
  • Information on places (tracks, villages) you're near

Vacancies

  • An embedded hardware programmer to help us implement a LUA/MicroPython interpreter on the ESP32

Hardware

The badge will be a creditcard-ish sized PCB with on it:

  • A 2.9" e-paper display
  • An ESP32 WiFi module
  • At least up/down/left/right/select buttons for input
  • A decent-sized battery to last at least a day
  • Power regulator
  • A USB->TTL chip for programming
  • ('would be nice') Proper badge clip instead of a lanyard
  • ('would be nice') a pager motor for notifications

At the moment we're trying to keep the budget for the badge below €15, which is still quite a lot of money. Sponsoring might help reduce this amount.

Current state

Unfortunately the EPD reset pin is connected to a weird pin on the ESP WROOM 32 breakout IO20 .. good news is that it's probably NC https://github.com/SHA2017-badge/Firmware/blob/master/components/epd/pins.h#L8

Firmware currently displaying images up-side-down

Hardware

SHA Rev0.0.1 Dev

Software

Roadmap

  • Proof of concept by september - e-paper DONE
  • PCB prototype ordered by september - WIP (PCB design finished, waiting for ESP32)
  • (more prototype runs)
  • February 2017: Start mass production (design / parts finalized before this time)
