A look at recent events and member projects
While not exactly a tradition, we have these combination bbq / clean-up / build events at least a couple times a year. For example, last fall one of the center tables in the main room of the space was built, and last spring several members built the built-in wall-side table that is also in the main room.
A few of the other many accomplishments included: Brandon tackled the floors in the metal shop and beyond, Jay transferred items cluttering up common areas to the member and other storage shelves, Nick got the mask glowing again, and Liz guided several additions to our bios webpage.
Remember to stay tuned to our Meetup page to keep posted on future events!
An introduction to the arduino, the development software, and interfacing with basic hardware. The class will be broken up into two days, split one week apart. The first session will be an introduction to the arduino, and coding, and simple examples
The second session will be a deeper dive into the world of arduino using examples
No experience with arduino is necessary.

Member Stephen Chavez has been making waves again — following his presentation with an SSD member at Defcon 24, he travelled to China and won an award at the GeekPwn 2016 hacking contest. And now, just after his graduation from Metro State University in Denver, he has been featured on Denver’s 9News.
Stephen and friends have been hacking his electric wheelchair with the goal to make it semi-autonomous. Unable to talk, he uses a computer keyboard to communicate; a task that cannot be done while controlling the chair’s joystick. As a result, he cannot “talk” and “walk” at the same time. With a semi-autonomous chair, he can set it to follow a friend or drive on a path while avoiding obstacles — freeing his hands to type and communicate.
Stephen’s wheel chair is a product of PGDT. The chair utilizes a proprietary protocol that runs over the same CAN interface found in all late model cars and trucks. PGDT calls the protocol R-net. R-net is deployed on the wheelchair to allow the various devices and interfaces on the vehicle to communicate with each other. There are no public documents about the R-net protocol. Stephen worked with a team of hackers to reverse-engineer this protocol and take control of the wheelchair’s internal network. “We’ve learned that power wheelchair hacking is also closely related to car hacking”
