BADGEr, which you can see in the photo below, is based around a 2.7" RePaper display made by Pervasive Displays (one of E-ink's manufacturer partners). It runs on a minimally capable CPU, is powered by a button cell battery, has 5 programmable buttons, and a microSD card for storage.
The Repaper display has a resolution of 264x176 pixels. It's the largest of the 3 E-ink screen sizes that Pervasive Display makes for the DIY market and it is supported by open source software.
The BADGEr was developed by WyoLum in partnership with Seeed Studio and Repaper. According to Wyolum, the controller chips and circuit design in the BADGEr are "Arduino compatible", meaning that if you get your hands on a BADGEr you can use Arduino software tools to program it.
But at this point there is little chance that will happen. It's not available commercially (and there are currently no plans to put it on the market) so if you want one you will need to attend Open Hardware Summit 2013. And you will have to register early; only 500 BADGErs were produced.
Here's a video showing one of the prototypes in action:
I doubt I will be able to make it to Boston in the first week of September, and that's a shame. I've been wanting a conference badge like this ever since I was in Vancouver for SID Display Week 2013. I was inspired by the DIY kits (based on E-ink screens) on display in the E-ink booth and wanted to craft a custom conference badge.
And then they added more features.
This conference badge came across my desk today because of a new feature which was just added. WyoLum has created a reading app which runs on the badge.
Assuming anyone wants to read on a credit card sized screen, it's now possible.
The app, which I'm pretty sure is technically an image viewer and not a reading app, displays page images that have been formatted to fit the 2.7" screen. Wyolum also posted a copy of Crime and Punishment which had already been converted to run on the BADGEr.
It's difficult to convey just how much I want to buy a BADGEr, but right now I am seriously considering paying $90 to register for the conference - just to get the badge.
Yes, I am that crazy, but can you imagine how much fun it would be to use this at other tech conferences? It would be the ultimate one-upmanship.
