PiKon and other Pi projects from Sheffield University

Sheffield has been a maker city for many years – the thriving steel industry dates back to the 14th century. Today it has the likes of Pimoroni, who recently moved in to a huge new factory, making cases, HATs, media centres and more. The good ship Pimoroni The University of Sheffield has been undertaking a number of Raspberry Pi projects in the last couple of years. The computer science department has a research group called Sheffield Pi-Tronics led by Hamish Cunningham. One project of note is their new Pi-powered telescope – PiKon. Not to be confused with PyCon… The £100 3D printed Pi-powered telescope The University has released incredible images of the moon taken with the Raspberry Pi’s camera module connected to a 3D printed telescope which costs just £100 to make from readily available parts. The moon Moon, the The Pikon astro-cam is a collaborative project by the Department of Physics at the University of Sheffield and Mark Wrigley of Alternative Photonics, a small company based in north Sheffield. The project was set up to deliver a working telescope for the Festival of the Mind event. They have a working model and they’re aiming to make all the 3D printing resources and instructions available soon. They’re also looking for help producing a simple interface to make it more accessible to all: So far, we have a working telescope which is operated by entering command lines into the Raspberry Pi. We are looking for enthusiasts and educators to help us take things further. We want to encourage people to create, innovate, educate and share their efforts on an open source basis. pikonic.com How it works (from pikonic.com): The PiKon Telescope is based on the Newtonian Reflecting Telescope. This design uses a concave mirror (objective) to form an image which is examined using an eyepiece. The mirror is mounted in a tube and a 45 degree mirror is placed in the optical path to allow the image to be viewed from the side of the tube. The PiKon Telescope is based on a very similar design, but the image formed by the Objective is focused onto the photo sensor of a Raspberry Pi Camera. The camera sensor is exposed by simply removing (unscrewing) the lens on the Pi Camera. Because of the small size of the Raspberry Pi Camera board, it is possible to mount the assembly in the optical path. The amount of light lost by doing this is similar to the losses caused by mounting the 45 degree mirror in a conventional Newtonian design. Former physicist and member of the Institute of Physics, Mark Wrigley, said: We've called this project Disruptive Technology Astronomy because we hope it will be a game changer, just like all Disruptive Technologies. We hope that one day this will be seen on a par with the famous Dobsonian ‘pavement’ telescopes, which allowed hobbyists to see into the night skies for the first time. This is all about democratising technology, making it cheap and readily available to the general public. And the PiKon is just the start. It is our aim to not only use the public's feedback and participation to improve it, but also to launch new products which will be of value to people. Also this week the group launched Pi Bank – a set of 20 kits containing Pi rigs that are available for short-term loan. This means local schools and other groups can make use of the kits for projects without having to invest in the technology themselves, with all the essentials, plenty of extra bits to play with – and experts on hand to help out.

If you’re interested in the history of Sheffield there’s a great documentary you should watch called The Full Monty.
