YouTube user Phaxmohdem has built a 15 Raspberry Pi 2 (60 core) supercomputer cluster into a portable toolbox. He is using a 300W power supply for it but it only draws about 45W when under full load. He’s done some benchmarks but hasn’t said what he’s using the cluster for (although the comments section has some suggestions. *rolls eyes*) Watch the video above for a little tour or visit the YouTube video page.
Southend Raspberry Jam are holding an event at the Temporary Arts Project on North Road in Southend-on-Sea this coming Monday. The event runs from 1pm-8pm and various sessions are planned including: a beginners session, a Sonic Pi session, an Astro Pi session and a session on micro:bit programming. There is also a training session planned for current and future mentors. You can book tickets on EventBrite via the embedded widget on this page.
Jeff Dahl is an Elementary School teacher in Michigan. His class has been using the Raspberry Pi and their main project has been to build robots. They’ve taken this a bit further and, by customising a GoPiGo kit from Dexter Industries with bits of K’nex, they’ve created two robots capable of facing off against each other in a game of soccer (or football depending on which side of the Atlantic you’re on).

Ben Finio’s wife plants a large vegetable garden every year but eventually grows tired of maintaining it. I can sympathise. A lot. So, Ben decided that he could use a Raspberry Pi to automate the watering process. He has set his sights low and uses the Weather Underground API to determine if it rained the day before. If it didn’t, then garden is watered by his irrigation system. Read the Instructable of how he did it here.
James Poole, who recently gave us a great way to put a Raspberry Pi Zero inside a SNES controller, has branched out into robotics. He’s gone about it the old-fashioned way by using an H-bridge chip to drive two motors attached to a chassis with the Pi onboard. He’s then hooked up a USB webcam to allow him to see where he’s going. He has open-sourced all the code to do it and released it on GitHub. Take a look at his blog for more details on how to install the software and wire up the circuit.
Just a quickie!
