Raspberry Pi used as a Rubik’s Cube solving machine

by  •  • 0 Comments

Francesco Georg has used a Raspberry Pi, a Camera Module, LEGO bricks, some EV3 motors and a BrickPi add-on board to create this Rubik’s Cube solving robot. He figured out how to use a two-phase algorithm developed by Herbert Kociemba via a Python library he found on GitHub (Open Source FTW). You can chat to him on the original Reddit thread and view a video of it in action above.

Raspberry Pi goes to Scout camp

by  •  • 0 Comments

I’ve just been reading about Ben Nuttall’s adventures at Wintercamp, a Scouts activity camp run at Gilwell Park in Chingford, UK. He was there, along with a set of Pi-Top Ceeds, to run activities described as “a gentle introduction to creative tech and experimenting with sensors”. You can read more about his time at the camp here.

Inspired by Ben’s field trip, I’m thinking about getting involved with future scouting activities as part of my role as a Pi-Top Champion.

Reading sensors remotely using an ESP8266 board and a Raspberry Pi

by  •  • 0 Comments

Alex Eames took a (cheap as chips) Wemos D1 mini (which has an onboard ESP8266 wifi chip), connected it up to an analog temperature sensor and then flashed a script to the board that would send the sensor readings to a Raspberry Pi. The Raspberry Pi runs a PHP server and a script that accepts the data and displays it to your web browser, logging it out to a CSV file at the same time. He’s written the whole thing up as a tutorial with all the code and you can take a look at it here.
