@Alex Camilo , @AVR , @Jimmie Rodgers , @Andrew Sowa and I are all at Artisan's  Asylum tonight and the badge firmware is coming together quite nicely!

Thanks so much to Artisan's Asylum for giving us space to bring this badge project to completion!

Tomorrow night (Wednesday):

Pre Open Hardware Summit meetup and Fellowship fundraiser https://www.eventbrite.com/e/pre-open-hardware-summit-meetup-and-fellowship-fundraiser-tickets-50343178803

Thursday:

Open Hardware Summit!

http://2018.oshwa.org

The official firmware will be MicroPython-based.  However, I wanted to document an Arduino sketch and libraries that can be with the e-paper display on the bage.

The GitHub repo is here:

https://github.com/oshwabadge2018/arduino-epaper-demo

Instructions:

• Install the latest Arduino IDE and add the ESP32 board options to the Board Manager:
  • https://dl.espressif.com/dl/package_esp32_index.json
• Make sure the board is set to "ESP32 dev module"
• Make sure the serial port is the serial adapter.
• Wire up GND, RX, TX to the FTDI.
• Connect the IO0 pin to GND.
• Insert Batteries
• The module should power up and go into programming mode (IO0 low on powerup or reset)
• Click program in the Arduino IDE.
• The board should program.
• Un-ground IO0 and remove and reinsert the batteries.
• If this does not work then swap RX and TX and repeat the process

Methods to connect the wires:

• remove battery back to expose the bottom of J1 header and solder a 6 pin header on J1
• solder wires to J1 on the front the badge (and leave battery pack in place)
• use a 6 pin pogo pin adapter. I used an AVR ISP pogo pin adapter and connected to an 3.3V FTDI cable from Adafruit

All 300 badges assembled by Screaming Circuits have arrived!

Thanks to Duane Benson and the rest of the team at Screaming Circuits for all the support on this project.

Thanks to @Zapp @Hyr0n and the ANDnXOR badge team for the suggestion of custom printed dye sublimation from CustomLanyards4All.  We selected the doubled ended lanyard with plastic j-hook upgrade to avoid the metal hook from shorting out any connections:

We ordered quantity 330 lanyards to have some extra in case of any issues.  The planned number of badges is 300.

The shipment just arrived today!

The boards are currently being assembled by Screaming Circuits thanks to a generous offer from Duane Benson.

Here is what the final PCB looks like (rev 4):

OSH Park shared project for the Rev 3 by @Alex Camilo :

We expect this to be the final revision.  

Timeline:

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.

Rev 2 photos:

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! :)

Open Hardware Summit 2018 badge has now officially been certified as open source hardware by the Open Source Hardware Association. 

UID is: US000133

Also, @Alex Camilo created a this GitHub repo to act as the OHS18 Badge Documentation website: Page 

https://github.com/oshwabadge2018/oshwabadge2018.github.io

quick update for those that have not been following along with this project's chatroom.

@Alex Camilo has been doing FANTASTIC leading the design of the OHS18 badge!

Here is video of prototype designed by @Alex Camilo  : https://www.youtube.com/watch?v=GLpCBzm6ff0

Photo of Rev 2 prototype:

And here is render of preview of our Rev 3 prototype:

I got this suggestion from AND!XOR for custom lanyards:

https://www.customlanyards4all.com

They recommended doing 

"DYE SUBLIMATION LANYARD"

https://www.customlanyards4all.com/dye-sublimation-lanyards/dye-sublimation-full-color-detail

Any thoughts about width?

I think I'd like either 1" or 3/4".

Thanks,

Drew
