ISS tracker with a Raspberry Pi and Unicorn HAT

by  •  • 1 Comment

Carl Monk’s really done a great job on this.

Here’s an ISS tracker using a Raspberry Pi and the 8×8 Neopixel matrix of a Unicorn HAT. The Pi reads in the current co-ordinates and then plots the position on the Unicorn which has a paper overlay of a map of the Earth. It uses a different colour when it’s on the ‘non-visible’ side of the Earth. Carl has open-sourced all the code and the paper overlay and has posted it to his blog with an explanation of the project. Read about it here. You can see a short video of it working below:

Duelling pianos with Raspberry Pi play Street Fighter

by  •  • 0 Comments

This is an absolutely incredible project that mixes art and technology. Absolutely astonishing – read on!

To celebrate the re-opening of the Maison de la Radio, France’s principal and historical radio building situated in the heart of Paris, a team developed a system, called Pianette, whereby two upright pianos could be used to play a game of Street Fighter! They used a combination of piezo pressure sensors and analog-to-digital converters to supply Raspberry Pis with a musical control signal which was then converted into movement inside the game. The build, which was restricted to 41 days (!) because of the re-opening date, was on an epic scale and much of the time the team only had one attempt to get it right. You can see a video of a battle below and read more about the build on their blog. All of their code, and the design files for the various boards they created, are available here.

Q&A with Raspberry Pi’s Upton and Hollingworth

QA

 Matt Timmons-Brown (The Raspberry Pi Guy) visited Pi Towers this week and interviewed Eben Upton and Gordon Hollingworth. He had previously reached out to the community to get a pool of questions, which was a great move on his part, and these prove to be probing and the answers informative, with a lot of technical detail thrown in. If you want to hear direct from the horse’s mouth about things like the 2A+, the Compute Module 2, AstroPi and the roadmap for the software stack, have a look below. Make sure your speakers are turned up a fair way – Eben in particular is quite softly spoken and it sounds like the interview was conducted during lunchtime of Picademy! 🙂
