Last weekend was the Open Hardware Summit in Philadelphia, and the attendees were nearly entirely people who build Open Source Hardware. The definition of Open Source Hardware has been around for a while, but without a certification process, the Open Hardware movement has lacked the social proof required of such a movement; there is no official process to go through that will certify hardware as open hardware, and there technically isn’t a logo you can slap on a silkscreen layer that says your project is open hardware.
Now, the time has come for an Open Hardware Certification. At OHSummit this weekend, the Open Source Hardware Association (OSHWA) announced the creation of a certification process for Open Source Hardware.

Electronic conference badges have been around for at least a decade now, and they all have the same faults. They’re really only meant to be used for a few days, conference organizers and attendees expect the badge to be cheap, and because of the nature of a conference badge, the code just works, and documentation is sparse. Surely there’s a better way.
Enter the Hackable Electronic Badge. Ever since Parallax started building electronic conference badges for DEF CON, they’ve gotten a lot of requests to build badges for other conventions. Producing tens of thousands of badges makes Parallax the go-to people for your conference badge needs, but the requests for badges are always constrained by schedules that are too short, price expectations that are too low, and volumes that are unknown.
There’s a market out there for electronic conference badges, and this is Parallax’s solution to a recurring problem. They’re building a badge for all conferences, and a platform that can be (relatively) easily modified while still retaining all its core functionality.

[Jeremy Blum] converted his 2013 Open Hardware Summit badge, also known as the BADGEr, into an ePaper weather station. We’ve looked at the 2013 OHS badge in the past, and the included open source RePaper display makes it an interesting platform to hack.
To fetch weather data, the badge is connected to a Raspberry Pi using an FTDI cable. A Python script uses the Python Weather API to poll for weather data. It then sends a series of commands to the BADGEr using pySerial which selects the correct image, and inserts the current weather data. Finally, a cronjob is used to run the script periodically, providing regular weather updates.
If you happen to have one of the badges, [Jeremy] has provided all of the files you’ll need to build your own weather station on Github. Otherwise, you can take a look at the RePaper project and WyoLum’s eReader Arduino Library to build your own ePaper project.
The 2013 Open Hardware Summit took place on September 6th at MIT. There was a wide array of demos and talks covering Open Hardware methodologies and projects. After the break I’ll be covering the demo area of the conference, and sharing some of my favorite demos.
