Make your own sous-vide cooker with the #RaspberryPi and the Wolfram language

by  •  • 1 Comment

The Foundation have just had a guest blog post put up from Allison Taylor of Wolfram Research. In the post, she describes Diego Zviovich’s work to create a DIY sous-vide cooker with a Pi, an MCP3008 analog-to-digital converter and a couple of thermocouples. The whole system is controlled by the Pi running the Wolfram Mathematica programming language. Well worth a read if you want to explore the functionality of Mathematica. You can also do this sort of thing in Python, I hasten to add! Read the Foundation’s blog post here.

Here’s Diego himself giving a demo of the circuit and programming:

Cambridge Junction, along with Cambridge University Faculty of Education and The Raspberry Pi Foundation have been given £124,633 by the Digital R&D Fund for the Arts. The money will go towards developing Sonic Pi, which seeks to teach programming using sound and music, and using it in both formal and informal teaching. More information is available from the Cambridge News website.

Morse code translator with the #RaspberryPi

I haven’t got much detail on this project, but thought I’d share it anyway.

13-year old Kyle Seaman has used a Raspberry Pi to take keyboard input and translate what he types into morse code. The morse code is then tapped out on an old-fashioned telegraph key (shown in the foreground of the picture above).

Fantastic to see what a youngster can do with the Pi and a worthy project to try and replicate.

Review of the #RaspberryPi Wolfson audio card

by  •  • 1 Comment

Linux User and Developer magazine has posted it’s 4/5 review for the Wolfson Audio card. The card allows high quality input and output of audio through the GPIO pins and uses the P5 header of rev 2 Pis. It appears to be a good bit of kit but the software lets it down and is still very young. Read the review here. You can buy one of these cards from various suppliers including The Pi Hut for around £30.
