Paul Brown has blogged about some code publicly released by another Paul Brown. The code, when installed, will allow you to play the game of Snake on a Unicorn HAT using the arrow keys for control. You can view the code here.
Capacitive touch HAT for the Raspberry Pi
Adafruit have just made available to buy a new HAT add-on board. It has pads for up to 12 touch devices (you can use fruit!) and plugs nicely into the GPIO, just as any HAT should. You can read more and order one here. If you’re in the UK, you’re best off contacting Makersify and they’ll import one for you.
Raspberry Pi aeroponics system
Instructables user darkstar1 has documented his project which uses a fogger/mister machine and a PowerSwitch Tail II to create a Pi-controlled aeroponics system to grow plants from cuttings. You can read how he did it here.
Home arcade experience with the Raspberry Pi
Cabe Atwell wanted an authentic arcade experience at home. So, he built a replica of the Street Fighter 2 control console and a metal dance mat and has now hooked up a Raspberry Pi using emulation software. The console and the dance mat are hooked up to the GPIO and he’s finally got the home gaming environment he always wanted. Many years in the making, you can read more on the Raspberry Pi Foundation blog and also at Element 14. You can see it in action below:
Replicate multiple SD cards at once with dcfldd
This is a handy, albeit brief, tutorial and explanation from Richard Hayler in which he uses the enhanced Linux dd utility dcfldd to write an SD card image to multiple SD cards at once. Read how to do it here. Very handy for those of us who face the prospect of upgrading loads of SD card images for Raspberry Jams!
Use a Raspberry Pi and a cheap dongle to track aeroplanes
London-based Sopwith has taken a DVB-T dongle, plugged it into his Raspberry Pi and used software packages and scripts he has written himself to create an aeroplane tracker that plots onto a map. Read how to do it by viewing this PDF or read an introduction to the project on his blog. It’s a great tutorial and, as he says, it’s a great way to get your kids learning with the Pi.
