New robot kit for the #RaspberryPi

by  •  • 1 Comment

Simon Monk has launched a new robot kit based around the Pi. It includes the following for £55:

  • a robot chassis, including two gearmotors, two wheels and a 6 x AA battery holder.
  • a RaspiRobot Board v2 (RRB2) that plugs onto the Raspberry Pi and controls the motors, as well as providing power to the Raspberry Pi itself. It uses a switch-mode power supply that can provide the Pi with up to 2A of current. Plenty for a WiFi dongle, display and pretty much anything else that you might want to attach to the Raspberry Pi.
  • an HC-SR-04 Ultrasonic rangefinder
  • nuts and bolts to hold everything together

A completely new musical instrument powered by a #RaspberryPi

by  •  • 1 Comment

I’ve just seen this over on the Raspberry Pi Foundation’s blog and I just had to share it with you just in case you’re not following them (which you should!)

David Sharples from the University of Pennsylvania needed a subject for his senior design project on his BSE degree. So, he decided he would build a musical instrument with a Raspberry Pi. The end result is the Joytone – a large pad of joysticks that play different sounds at different pitches. It’s truly an astounding project that is a thing of beauty. Read more on the Foundation’s blog or read the full account of the build over on David’s blog. There’s a video embedded below which gives you a feel for what the instrument can do.

Run a QuakeWorld server on your #RaspberryPi

by  •  • 6 Comments

Sorry everyone. Looks like the downloads have disappeared.

RawShark has been looking at running QuakeWorld on his Pi and has now come up with a way to do it. Here are his instructions (reproduced from his original thread):

1. download nQuakesv (linux server version) from http://nquake.com/

2. Use the script to download and install everything. Answer no to both “QTV” and “QWFWD” – no binaries yet for Pi

3. go to nquakesv / folder and backup mvdsv and ktx/qwprogs.so (rename)

4. download the raspberry pi binaries of these files from here:http://files.quake.ie/linux/quake/mvdsv-ktx-raspberrypi.zip

5. give +x permissions to mvdsv (its called the multiview server and replaces the old qwsv binary)

6. add pak1.pak to /id1 folder if you have that file

7. to start your server, type ./run/port1.sh

Shazaam! The server has started in 28501 port.

If you want to actually PLAY on the Pi, use this pre-compiled client binary:http://files.quake.ie/linux/quake/fte-raspberrypi.zip
