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 →
The Raspberry Pi often makes the world a better place. This time, it’s helping to test 3D-printed stents using a smart stent-testing robot. Stents are small tubes used to prop open a patient’s airway. They keep people alive, so it’s incredibly important they don’t fail. In fact, the FDA (Food and Drug Administration) requires testing of each design by … Continue reading →
Parking can be a challenge in big cities like San Francisco. Spots are scarce, regulations are confusing, and the cost is often too darn high. At the TechCrunch Disrupt hackathon recently, John Naulty reached for a Raspberry Pi to help solve some of his parking problems. John explained that the parking spots near his home … Continue reading →
Working here at Pi Towers, I’m always a little frustrated by not being able to share the huge number of commercial businesses’ embedded projects that use Raspberry Pis. (About a third of the Pis we sell go to businesses.) We don’t get to feature many of them on the blog; many organisations don’t want their work replicated by … Continue reading →
Becky Stern suffers from that same condition that many of us apartment dwellers are affected by: a curiosity about who is making noise outside the door. Living within a large New York City apartment, Becky wanted to be able to see out of her peep hole without having to leave her desk. After all, the constant comings … 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 →
Bees are important. I find myself saying this a lot and, slowly but surely, the media seems to be coming to this realisation too. The plight of the bee is finally being brought to our attention with increasing urgency. In the UK, bee colonies are suffering mass losses. Due to the use of bee-killing fertilisers and pesticides … Continue reading →
Over in a land of palm trees and breezy sunsets, Adafruit’s Noe Ruiz has been making things. (My Noe story: I waltzed up to him in the Adafruit factory once, grabbed his hand, pumped his arm up and down and said: “SO good to see you again. How’s your brother?” He looked deeply confused. Turns out we’d never … Continue reading →
So, England, nominally the home of football, is out of the European Cup, having lost to Iceland. Iceland is a country with a population of 330,000 hardy Vikings, whose national sport is handball. England’s population is over 53 million. And we invented soccer. Iceland’s only football pitch is under snow for much of the year, and … 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 →
