Raspberry Pi Roundup - a Pi-controller telescope, a concussion sensor and a Hyperpixel radio


Gary Preston has developed the Astro Cat which:

is an auto GPIO configuring add-on board for the Raspberry PI 3 which provides additional hardware interfaces to communicate with and control a Meade Autostar, Moonlite focuser and temperature sensors.

Or, to the layman, it helps you to control your telescope and monitor the environment around it. He’s documented the process he took to develop the add-on board and open-sourced everything so, if you’d like to, you can reproduce his work. Follow his guide here.

Most interesting to me is that he’s documented the process for disabling the Pi’s Bluetooth functionality to re-activate UART on the default pins. You can find out how to do that on this part of his blog guide.


A Boston high school senior has helped to develop a system to monitor the risk of concussion in contact sports. Tiana Rossi, working alongside employees of Envision, used a Raspberry Pi and an accelerometer/gyroscope sensor to monitor the amount of force encountered by players which are then relayed back to the coaching staff to determine the risk of concussion. Read more about this project here.

Hyperpixel Radio

Giles Booth likes to make radios out of tech. This time, he’s taken a Pimoroni Hyperpixel and a Pi and installed on the SD card MPC and MPD which allows him to play streams or MP3 files. He’s then programmed the Pi using Python and the Tkinter library and made a touch-interface GUI to allow the user to select stations. Read how he did it here.
