PiWars – #RaspberryPi robotics competition – Coming in December 2014

by  •  • 3 Comments

At the February Cambridge Raspberry Jam, we announced “PiWars”.

PiWars will be a challenge-based robotics competition for wheeled robots to be held in Cambridge on 6th December.
Categories will include, for instance, a speed challenge, a maze navigation challenge and a line-follower challenge.
More information, including confirmed challenge categories, will be available soon on the CamJam website – http://camjam.me

I’ve started up a thread on the Raspberry Pi Foundation forum for any questions or discussions. If, for instance, you have any ideas about what challenges should be set, that’s the place to post them so that everyone can see.

I hope some of the subscribers to this blog will contribute to the discussion and, if possible, enter the competition! If you don’t fancy using the Forum, feel free to add comments to this blog post!

Overlay text and graphics on a #RaspberryPi PiCam photo and tweet it!

Alex Eames, at RasPi.TV, has been very busy recently posting a series of blog posts about using Tweepy on the Pi to send tweets. He has previously covered tweeting an image from a PiCam and now he’s moved on to overlaying the cam image with text driven from a weather station and some graphical elements. He’s even included the code necessary to do it.

Connecting an Arduino to the #RaspberryPi using I2C

by  •  • 1 Comment

There are several ways to connect an Arduino to a Pi. The simplest way is to just plug it into one of the USB sockets on the Pi. Peter Mount, however, needed to do things differently as he was already using his Model A’s USB port for something else. So, he went with the I2C bus. He’s detailed the process over on his blog, including the code you run on the Arduino and on the Pi.

14-year old student builds a cute portable #RaspberryPi

by  •  • 1 Comment

Jayme Gisbourne, who studies at Stewards Academy in Essex, has created this neat portable Pi set-up and called it the Porta-Pi. The main case is acrylic and he’s used a hack for the lcd screen pioneered by SK Pang. He has written extensive (and I mean extensive) instructions for this post on the Foundation blog. Really great project. I caught a glimpse of it at CamJam and it looks as cute in person as it does on screen!
