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 →
Today’s downpour notwithstanding, the UK has just experienced its hottest September day since 1911. Here at Pi Towers, we were acutely aware of this. The office roared with the noise from sixty-odd CPU fans at full tilt. The air conditioning conked out. And things got especially bad when we realised that it was buy-one-get-one-free day at the local … Continue reading →
So there was I, halfway through writing another blog post, when this landed on Twitter. Feast your eyes. It’s a Raspberry Pi robot that plays a pretty mean game of Connect 4. 4 Bot – Raspberry Pi Connect 4 playing robot Written in Python, uses the minimax AI algorithm to calculate moves. Plays a fairly … Continue reading →
Daphne the WonderCat is the feline owner of Kate Bevan, a tech journalist. Daphne is surprisingly active on social media for somebody who doesn’t have opposable thumbs; her Facebook is full of a mixture of (perfectly justified) boasting about her superbosity, and complaints about the inadequacy of her human support team. Bernie Sumption, an acolyte … Continue reading →
Myrijam Stoetzer, 14, and Paul Foltin, 15, are from Duisburg in Germany. They have built a system for controlling a wheelchair using eye movements. A standard webcam with the infrared filter removed tracks eye movements, and the eye is illuminated by (invisible) infrared light from LEDs to allow the system to work in low light … Continue reading →
Helen: Today we’re delighted to have a guest post from 17-year-old student Arne Baeyens, aka Robotanicus, who has form in designing prize-winning robots. His latest, designed for the line-following challenge of a local competition, is rather impressive. Over to Arne… Two months ago, the 24th of May, I participated in the RoboCup Junior competition Flanders, … Continue reading →
We first came across kegerators last year: it never ceases to amaze me how many of you use your Raspberry Pis to both simplify and massively overcomplicate your drinking. The kegerator is not a popular device here in the UK, but, judging by the emails I get from readers, there are enough of the things … Continue reading →
You’ve got a week to build this portrait, whose eyes follow you around the room, for Halloween. Adafruit have produced a tutorial, courtesy of Tony DiCola, which uses OpenCV and openFrameworks with your Raspberry Pi and camera board to create a picture of pullulating panic. It’s haunted hardware of horripilating hideousness. You’ll also find instructions … Continue reading →
I’ve been talking to Pierre Raufast for a little while now about his efforts to get OpenCV ported smoothly to the Raspberry Pi camera board (which is available from the usual suspects: head to the links under “Buy a Pi” at the top right). OpenCV is an open-source library for real-time image processing, and is … Continue reading →
Here’s a somewhat creepy mirror with a disembodied (French) voice, which recognises the person looking into it and responds accordingly. This lovely hack from Pierre Raufast is the sort of OpenCV application that we hope to see much more of when the camera board goes up for sale (and the Pi camera would be a … Continue reading →
