OSH Park is producing electronic conference badges for the 2018 Open Hardware Summit. The hardware has been designed Alex Camilo, based on concepts from the ESP trINKet by Mike Rankin. The badge features an ESP32 microcontroller and a 2.13″ E-Paper display.
OSH Park shared project for the Rev 3 by Alex Camilo :
We expect this to be the final revision.
It is ordered on Super Swift today and should be validated next weekend. This will allow us to order the full quantity PCB panels in August 13th. Assembly is estimated to be 10 business days from the day when all components and PCBs are received.

And for those interested, here is a link to a gallery:
Terminal output on Rev 2 prototypes:
The Rev 2 prototypes have NodeMCU boards soldered on to the back to serve as a USB to serial adapter.
One of the Rev 2 prototype boards that Alex sent me has the default e-paper demo:
The other has MicroPython installed! 🙂
Resources for the 2018 Open Hardware Summit badge:
Probably inspired by the successful Bootlin campaign for open source Allwinner VPU drivers, two days ago Maciei Suminski and Tomasz Wlostowski made Youtube video where they apeal for fund rising 30 000 CHF for the development of KiCAD v6! Everyone can show their support for the most successful open source PCB design tool at: https://givetokicad.web.cern.ch

KiCad presentation by Andrew Sowa at Teardown 2018:
While most PCBs can be simple rectangles, sometimes the design requires more complex geometry. EDA tools don’t always make this simple, so we will go over a few KiCad tips to make it easier. In this talk you will learn how to import unique board shapes from Fusion 360, create arbitrary fill zones using images, and embed high-frequency RF filters. We will use multiple software packages to enhance KiCad’s performance beyond its obvious use.
An Intro to KiCad – Part 6: Place Parts and Define Outline:
In Part 6 of the Digi-Key Introduction to KiCad series Shawn walks us through the board layout stage with pcbnew. Shawn will show us how to import a net list, arrange components, draw a board outline, and make trace connections.
