16 Amazing Things You Can Do With a Raspberry PI

The Raspberry Pi is a 35$ nano-computer that can do a lot

1. a print server

Old printers can be refurbished into wireless printers using a Raspeberry PI. This makes it a very cheap solution.

2. a GPS Tracker

Stuart Johnson has created a GPS Tracker, combining a Raspberry PI with a GlobalSat BR-305 GPS Receiver which has a RS232 connection and a program written in Mono C#.

3. a Geiger Counter:

A more advance project incorporates a GPS Tracker and Zigbee wireless less system.

4. Home Robotic:

I've managed to make the Raspberry Pi work as a speech recognition module to control a robotic arm with a USB interface. This is related to my previous video (, and as usual I've posted instructions on how to get it working on my website:

10. reviving a retro computer

retro Back in 1988, I was the happy owner of the faster personal computer at the time : an Acorn Archimedes , running RiscOS. In fact the ARM 11 processor, which is the core of the Raspberry PI has a long history. The Acorn Archimedes was the first computer equiped with a ARM based CPU. The instructions to install this 25 year old mythic Operating system on the RPI can be found here : RISCOC for Raspberry Computer.

I have a stack of old RISC OS machines including an Iyonix. I loved them. Best UI ever and still. But they don't have all the games and hardware of Windows or the internet ability of Linux. So it's been a while since I used one. When I heard a that RISC OS would run on the Pi, I had to try it for myself! Brilliant. Here's me trying it for the second time.

12. a coffe machine

yes ! a coffee machine

13. Build your own 3D printer

Raspberry pi to 3D print with webinterface in node.js

Well wanting to have an autonomous way of printing my 3d objects. Did it with the cheap raspberry pi! This way you can have farms of printers and all control them with some clicks in your browser. I finally had some time to clean it up and post on github here:

14. Weather Station

Connecting 2 temperature sensors, light sensor and a barometric pressure sensor on a Raspberry to build a weather station. on

I've finally got my Weather Station with temp sensors, light sensors and a barometric pressure sensor onto a nice compact board which sits on top of the Raspberry Pi. Video goes with this blog article

Why not use the "Solar Battery Cells" propepsed by cottonpickers to make this weather station autonomous ?

15. a Near Space Craft

16. a HPC Computer

A Southampton university team and a 6 year old Lego specialist has built a HPC computer composed with a cluster of 64 Raspberry PI

Building a High Performance Computer ourself with a aim to inspire the next generation of scientist and engineers.

Supercomputer get built using Raspberry Pi and Lego

Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego. The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O'Brien, Mark Scott and Oz Parchment, along with Professor Cox's son James Cox (aged 6) who provided specialist support on Lego and system testing. Professor Cox comments: "As soon as we were able to source sufficient Raspberry Pi computers we wanted to see if it was possible to link them together into a supercomputer. We installed and built all of the necessary software on the Pi starting from a standard Debian Wheezy system image and we have published a guide so you can build your own supercomputer."
