Instrutables user Scavix has put together this great step by step guide on building a networked, HD surveillance camera using the Pi and associated components.
- Network access to live video
- Storage & upload of recorded video
- Motion detection & alerting
- Night vision (with the IR camera & lights)
- All weather housing
The housing is up to you but the rest is standard Pi components and the Raspian operating system.
A new post over on the official Raspberry Pi blog features a new Linux magazine called Linux Voice. This mag has a couple of subtle differences to make it a bit more FOSS friendly.
Firstly, 50% of the profits will be invested back into the OSS community. The recipients will be chosen by the readers so it’s all kept fair.
Secondly, nine months after release, each issue and all content will be released under the Creative Commons Attribution ShareAlike Licence (CC BY-SA)
You can find out more (and grab a subscription) on their IndiGogo page but we agree with the Rasp Pi guys that this is a fantastic alternative to traditional publishing models.
Or you can wait 9 months and we’ll re post each issue as soon as the open licence kicks in!
Geeky-Gadgets.com have a feature (and video) on building an old school arcade cabinet powered by the Pi. The project looks brilliant and you can be part of it by helping fund their Kickstarter campaign!
Dave is using the finished device as a flight readiness indicator but the post is a great read even if that’s not your thing as he covers a couple of useful techniques for working with non (out of the box) pi friendly hardware.
The Raspberry Pi Foundation and Wolfram research have teamed up to bring Mathematica to the Pi.
What is Mathematica? Well according to the official Matematica site:
Almost any workflow involves computing results, and that’s what Mathematica does—from building a hedge-fund trading website or publishing interactive engineering textbooks, to developing embedded image-recognition algorithms or teaching calculus.
Mathematica is renowned as the world’s ultimate application for computations. But it’s much more—it’s the only development platform fully integrating computation into complete workflows, moving you seamlessly from initial ideas all the way to deployed individual or enterprise solutions.
All future downloads of Raspian will include the software be default but you can get it now but running the following in an LXTerminal Window:
sudo apt-get update && sudo apt-get install wolfram-engine
It’s a pretty hefty download (some 600mb) so make sure you have enough space on your SD card and a bit of time for the packages to come down.

A bit more techy but the Pi makes a great, low power VPN server (or client).
Cyberpunk has a simple step by step to configure OpenVPN server on your Raspberry Pi running Raspian. It’s not for newbies as you’ll spend a lot of time in the terminal but it’s a great guide to setting up something that can be pretty complex if you start from first principles.
The Raspberry Pi has a pretty good range of different operating systems and disk images that can be downloaded turning your Pi into a media center, a Scratch development machine and much more.
But downloading and installing these images can be tricky. How To Geek has a great post covering a project called NOOBS which aims to make it dead simple to install one of the major OS. If you’re confused by all the advanced tutorials to get started then check this out!
Another day another cool Pi related project on Kickstarter.
This time it’s Kano – a build your own computer kit that features a Pi, a great keyboard with a built in track pad, a speaker and much more:
1 – Kano Books, illustrated and intuitive
2 – Kano OS and Levels on 8GB SD card
3 – DIY Speaker
4 – Raspberry Pi Model B
5 – Kano Keyboard Combo
6 – Custom case
7 – Card mods and stencils
8 – Stickers!
9 – Cables: HDMI*, Mini-USB
10 – Smart power plug (all region pins available)
11 – WiFi powerup
Prices start at around $100 but this kit includes pretty much everything you’d need to get up an running with your Pi so is worth a look!
