The ocular fundus is the interior surface of the eye, and an ophthalmologist can learn a lot about a patient’s health by examining it. However, there’s a problem: an ocular fundus camera can’t capture a useful image unless the eye is brightly lit, but this makes the pupil constrict, obstructing the camera’s view. Ophthalmologists use... Continue reading
Even you live somewhere heavily endowed with bats, you’ve probably never had a good look at one on the wing. Bats fly so fast – in poor lighting conditions – that if you’re lucky you’ll get a glimpse of something flashing by out of the corner of your eye, but usually you won’t even notice they’re there. Enter the... Continue reading
The new 8 megapixel Raspberry Pi camera board has been out for just over a month, and we’ve been seeing some really impressive work being done with it. As many of you know, we also make a version of the camera board with no infrared (IR) filter: the Pi NoIR. Version 2 of the Pi... Continue reading
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
First, in non-beetle-related news, this happened last night: There are two Raspberry Pis in the Cygnus spacecraft, the payload carried by the Atlas V rocket above, which are destined for the International Space Station, where they’ll be used to run kids’ space experiments as part of the Astro Pi project. We’ll have more information for... Continue reading
A few weeks ago Matt Timmons-Brown, The Raspberry Pi Guy, visited Pi Towers to interview Raspberry Pi Trading CEO Eben Upton. Over the course of an hour and a half, Matt drew Eben’s detailed answers on some of the topics that hundreds of you put forward in response to a call for questions. When might... Continue reading
We quite frequently get asked about optimum operating temperatures for the Raspberry Pi – frequently enough that this was a very early addition to our FAQs page back in 2012: The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9512 is specified by the manufacturers being qualified from 0°C...

As I type this, Emma is hugging herself and shouting “LOOK AT THE LOVELY BABY!” We believe that every office environment is enriched by biologists. The little guy/gal in the video above is a Tuatara – and I didn’t have to go to Wikipedia to learn more about them, because Emma is amazingly well-versed in... Continue reading
Edited to add: Naturebytes’ website is now up and running at http://naturebytes.org/. You can sign up to their newsletter for updates. Start-up Naturebytes hopes their 3D printed Raspberry Pi camera trap (a camera triggered by the presence of animals) will be the beginning of a very special community of makers. Supported by the Raspberry Pi... Continue reading
So your new Pi NoIR has plopped through the letterbox, and you’ve unpacked it. There’s a little square of blue gel in there. What’s it for? If you’ve been reading our posts about why we developed an infrared camera board keenly, you’ll have noticed that we mentioned a lot of interest from botanists, who use... Continue reading
