The hackable electronic conference badges are more and more being adapted in technical conferences and especially those for hackers and makers. These badges can be reprogrammed easily and could be used later as a development board.
It’s not the first time to hear about a hackable badge; for example, Parallax has an open source one with lots of features like: exchanging contact information over infrared, accelerometer, A/V jack and more. The badge can be programmed via USB using Propeller’s Spin (Propeller Tool or Propeller IDE) or C (Simple IDE) languages.
New designs for badges show up from time to time. The team behind SHA2017 (a non profit outdoor Hacker camp taking place in The Netherlands in 2017 on August 4th to 8th) had developed their own badge.
The new badge’s features:
- E-ink9″ display.
- Espressif ESP32 Wroom WiFi Module.
- MPR121 Touch Sensor and GPIO expander.
- TP4056 battery charger.
- SD Card.
- USB-UART bridge (converter).
- ×6 RGB LEDs.
The team’s goal behind SHA2017 consists of two parts: “augment the event”, like reading the lecture subtitles live around your neck; and ”be a development platform” where you can find all the needed parts to write your own application using MicroPython.
