Using the WordPress API to display stats on a 7-segment display with a Raspberry Pi

Richard Saville (Average Man) has been hard at work looking at the WordPress API. He’s managed to find the necessary guides to dig into the API and extract data for his blog. He’s then run this data through his own library for the ZeroSeg add-on board to display page hit stats on the 7-segment displays the add-on board provides. He’s documented the code with extensive examples over on his blog.

Learn to Code with C – new Raspberry Pi / MagPi book out

Learn to Code with C

The MagPi has announced the publication of a new volume in the Essentials series. Called “Learn to Code with C”, the book is written by Foundation developer Simon Long and covers the following topics:

  • Create variables & do arithmetic
  • Control the flow of your C programs
  • For loops and case statements
  • Understand and create functions
  • Work with arrays and strings
  • Interpreting user input
  • and much more

You can download it for free from The MagPi or get it via their apps.

Using Python to estimate your vocabulary – practical programming produces perfect picture

Alex Eames has been rediscovering the joy of practical programming and has come up with a great Python tutorial. The tutorial investigates the level of your vocabulary by importing a list of words and asking you whether you know what that word means. By using some maths, it then works out roughly how many words you actually know. Take a look at how he did it here.

Cheap as chips: the Raspberry Pi Zero in a botched-together games console

Just saw this over at The MagPi, so thought I’d share.

Joe Foulkes wanted to create an as cheap-as-possible gaming console. So, he took an old Samsung Galaxy box, a Pi Zero, some prototyping board and some other components and created BotchBoy. The build cost is about £15/$20 and is easily achievable by most beginner hackers with rudimentary soldering skills. Take a look here or view a video of it in action below.

NEC creates large displays with Raspberry Pi compute module

NEC have just announced that they are to produce large (>=40″) displays with an integrated slot for the Raspberry Pi Compute Module. The big news here is that they are planning to use the as-yet-unreleased-publicly Compute Module 3 (take a look at the image above, click to embiggen – that is a CM3 and it’s clear that although the form-factor remains the same, the design is slightly different from the CM1, pictured below!)

Raspberry Pi Compute Module 1

The news was announced at the Display Trends Forum in Rome on 10th October by Thomas Walter (Section Manager – Strategic Product Marketing) with a link-up to Pi Towers where Eben Upton (CEO, Raspberry Pi Trading) filled in some of the technical details:

During the broadcast, Eben confirmed that NEC has commissioned Premier Farnell to produce a special 16GB flash memory version of the CM3. This suggests an upgrade in flash memory from the default of 4GB, allowing much more space for other software in addition to the default Linux distro, which one assumes will be some variant of Raspbian – this appears to be confirmed by a later announcement on displaydaily.com.

So, what can we glean from this announcement? First of all, and this is a biggy, that Raspberry Pi is seen as a stable enough platform on which to base a major industrial product. NEC is no small-fry company and 40″+ is no small-fry display size. Secondly, that the Compute Module 3 is almost ready to be launched. I wouldn’t be surprised if we hear about the availability of the CM3 within the next couple of weeks. Certainly, it is very unlike Raspberry Pi Trading to reveal the imminent launch of anything, and I wouldn’t expect that to change any time soon, so it must be getting close! Thirdly, that the form-factor of the Compute Module is equally unlikely to change within the foreseeable future – industrial customers are using these modules now and they will want them to be swappable and upgradeable.

This won’t mean anything in particular to most of the Raspberry Pi community at large, of course, but it is reassuring to know that as well as the hobbyists, makers, educators, families and classes using the Pi, there is a healthy backing from industry to bolster the stability of the Cambridge-based company.
