Bike Hack Night VI

Bike Hack Night is a show & tell of bicycle-related apps, data visualizations, and gadgets. We are thrilled to be co-sponsored by REI, which has invited us to the REI Community Space at Wunder Garten as part of the #unitedoutside celebration. And thanks to co-sponsor Mobility Lab for making this event possible. REI will be providing s'mores, and beer will be available for purchase. At this point we are not expecting a food truck on premises, but you are welcome to bring your own food.

Doors open at 6:00. Speakers begin at 6:30. Because we're expecting a large crowd, consider bringing a laptop or tablet to follow along with the presentations. We'll link to them from We have seven presentations:

• Ryan Abrahamsen will show how Terrain360 maps bike trails to panoramic images. 

• Eric Brelsford will show you how to get your city's bike lanes into OpenStreetMap and talk about why you would want to.

• James Graham will present DDOT's new GIS street data, and bicycling Level of Traffic Stress analysis.

• Kate Rabinowitz will dig into Bike to Work Day 2016, By the Numbers.

• Alexandra Ulsh, Nelle Pierson, and Chris Slatt will show how DCFemTech and Code for DC built a map for WABA showing proximity to bike infrastructure.

• Justin Molineaux of Baas Bikes will show how smartphones can create low-cost, data-rich bikeshare systems. 

• Tom Lee will show how he collected bike safety data using ultrasonic sensors, ESP8266 wifi microcontrollers and smartphones. 

Thanks to Wunder Garten and Google for our speaker swag.

    Thank you speakers, Michael, and sponsors for the awesome talks!

    I wanted to post the information about our project that I briefly talked about in the today's event. We have recently launched Project Sidewalk (, a transformative new tool that enables anyone to *remotely* label sidewalk accessibility problems by walking through city streets in Google Street View! Our vision is to fundamentally change the way accessibility information about the built environment is collected and visualized. Imagine, for example, a navigation app that provides accessible routes for wheelchair users.

    Join us and make DC more accessible! If you are seeing this post on your computer, participating is as easy as: (a) visit , (b) click “Participate” and (c) complete a few short missions! So far, 167 users mapped the accessibility of over 297 miles of DC streets--that’s nearly 28% of all streets in the city. With just 15 minutes, you can make a difference!
