SHA2017 Conference Badge To Feature ESP32 SoC, e-Paper Display

In most conference, you’ll wear a badge showing your name, job description and company, but with the price of electronics going down, it may be time for a conference badge upgrade. SHA2017 is a non-profit outdoor hacker camp taking place in The Netherlands in 2017 on August 4 – 8, and the organizers are planning to use a special badge comprised of Espressif ESP32 processor, and an e-Paper Display.

Beside your name and company details, the badge could also be used for weather and timetable information. EAGLE files and firmware can be found on Github with more details also available in the Wiki. The price of the badge is still expected to be around 20 Euros, and they are looking for sponsors. If you’d like that badge and attend the conference, you’ll need a 250 Euros ticket for the 5-day event.

Thanks to Zoobab for the tip.

    That doesn’t look like Business card form factor

    Nope, typical example of a good idea but a wrong build. A badge dont need to be a dynamic thing. The good idea is to have reusable badge. Dont need a ESP, a cpu, memory card or anything like that.
    You should pick a blank badge, put it near a RFID antenae or similar to download the image / text, and that’s all ! Everything else rise the cost and increase complexity / bugs.

    You completely missed the point of this badge and the nature of the event. It is an event for hackers. People attending will be writing software for this badge, making hardware modifications/extensions and other stuff. The purpose of this badge is not just to be a simple reusable badge.

    I think they always wanted to make a devkit since it’s a hardware hacker conference.

    @Deets
    They are using GDEH029A1 display. It’s sold for $9.30 @ http://www.buy-lcd.com/index.php?route=product/product&product_id=50472
