The 5-megapixel visible-light camera board was our first official accessory back in 2013, and it remains one of your favourite add-ons. They’ve found their way into a bunch of fun projects, including telescopes, kites, science lessons and of course the Naturebytes camera trap. It was soon joined by the Pi NoIR infrared-sensitive version, which not... Continue reading
The Scratch programming language, developed at MIT, has become the cornerstone of computing education at the primary level. Running the Scratch environment well was an early goal for Raspberry Pi. Since early 2013 we’ve been working with Tim Rowledge, Smalltalk hacker extraordinaire. Tim has been beavering away, improving the Scratch codebase and porting it to newer... Continue reading
When someone rings my doorbell at home, I walk to the door to find out who’s there. For those of you with larger homes, I know that it can be challenging to get there in time to release the hounds. With you in mind, Kishore Gaddam has put together a tutorial showing how you can... Continue reading
Another update: I managed to miss Baruyr Mirican and Darshan Gopal from the Broadcom test engineering team off the list too. My grade this year is D: must do better. Update: I did a rather poor job of collating the credits list this time. Apologies to Aravind Appajappa, Jeff Baer, Saran Kumar Seethapathi and Noumaan... Continue reading
Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose...

When we announced the Raspberry Pi 2 back in February, we said that we’d continue to support its predecessor, the Raspberry Pi Model B+. Since then, we’ve sold well over a million units of Raspberry Pi 2, but Model B+ has also continued to sell very well, despite also costing $35. A side effect of... Continue reading
People have been emulating classic computers and games consoles on Raspberry Pi since we launched back in 2012. For those of us who bough our first hardware in the 1980s, this is a fun way to take a trip down memory lane, but our relatively modest CPU performance restricted us to third– and fourth-generation platforms. Anything with... Continue reading
Let’s get the good stuff out of the way above the fold. Raspberry Pi 2 is now on sale for $35 (the same price as the existing Model B+), featuring: A 900MHz quad-core ARM Cortex-A7 CPU (~6x performance) 1GB LPDDR2 SDRAM (2x memory) Complete compatibility with Raspberry Pi 1 Because it has an ARMv7 processor,...

Since Broadcom released complete documentation for the VideoCore IV GPU back in February 2014 we’ve seen a number of fun uses of our 24GFLOPs of QPU compute, from Andrew Holme’s FFT library to Pete Warden’s deep learning experiments. It’s not unusual to see a 10x increase in performance over the ARM for algorithms with a... Continue reading
Eben: Here’s a guest post from Tom Sherlock, describing how he’s been able to control a telescope using a Raspberry Pi, Mathematica and the Wolfram Language. As an amateur astronomer, I’m always interested in ways to use Mathematica in my hobby. In earlier blog posts, I’ve written about how Mathematica can be used to process... Continue reading
