Ethan Rose’s PocketC.H.I.P. with a software defined radio attached

This week the community is using C.H.I.P. as the brain of a competitive robot, PocketC.H.I.P. and software defined radio to decode and track airplanes, and 3D printing and old consumer electronics to personalize their PocketC.H.I.P. enclosure.

No matter what you’re doing with C.H.I.P. and PocketC.H.I.P., share it with the community. Snap a photo and share it on Twitter, message us on Facebook, or join the conversation in the forum. No matter how you decide to participate, C.H.I.P. and PocketC.H.I.P. are more fun when you share.

Push Your Way to Victory with SumoC.H.I.P.

Lauri Võsandi and Silver Kuusik built SumoC.H.I.P., a ~$30 sumo robot that uses C.H.I.P. as its brain. They even wrote great instructions so you can build your own! The duo are members of the Robotics Club at the Estonian Information Technology College. Since 2002, the group has been building robots, teaching fellow students, and participating in Robotex, a three day robotics extravaganza with heavy focus on Sumo-style competition.

In Robot-Sumo, two autonomous bots compete in a dark-colored ring with a white perimeter. Each robot-wrestler attempts to push their competition out of the ring for fame and glory.

Towards this goal, SumoC.H.I.P. is equipped with 8 pairs of infrared emitters and receivers that help it to navigate the ring and detect the opposing robot. Using two large wheels attached to servo motors, the SumoC.H.I.P. rests much of its weight on its front blade in order to drive its opponent to the edge of the ring.

Here’s a sampling of a typical SumoC.H.I.P. bout –the robots survey the ring, then suddenly spring into action to push their competition out.

Best of luck to the entire team as they compete in this year’s Robotex competition!


Track Planes with PocketC.H.I.P. & Software Defined Radio

If you’ve ever looked up at a plane over head and wondered its flight plan, then Ethan Rose’s latest project will interest you. Using PocketC.H.I.P. with a software defined radio (SDR), Rose is able to decode airplane transponder data and display the data on PocketC.H.I.P. in real-time.

Planes these days broadcast flight info like altitude, airspeed, destination, using an automatic dependent surveillance-broadcast — ADS-B for short. To access this information, Rose is using the dump1090 application (it’s called that because 1090 is the broadcast frequency for plane transponder data).

Setup and installation of the project are straightforward. Plug the USB-based SDR into PocketC.H.I.P., update and install some required software, and run dump1090. Rose provides full instructions in his post that are clear and easy to follow.

The State of the PocketC.H.I.P. Case Hack

Over the nearly 400 messages in the PocketC.H.I.P. Case Mod, Customization and Decoration thread, Pocketeers have been working to make the keyboard, D-pad, and even entire case fit their own style and comfort requirements.

MidHeavenTech has taken the approach of carefully measuring PocketC.H.I.P. and using software and a 3D printer to realize a new design (above).

Werew takes a different angle, and uses parts from old devices to spruce up the PocketC.H.I.P. keyboard. In the latest mod, Werew pillaged keys from the Motorola Moto F3 and carefully applied them over the PocketC.H.I.P. D-pad. From the looks of it, everything fits quite nicely.

Imagine the color combinations you could make with CCTV_Adult's great idea!

And then there is Twitter user CCTV_Adult who has taken circular rubber bumpers and applied them to each and every key on PocketC.H.I.P.! It’s an ingenious little hack that CCTV_Adult executed perfectly.
