- This is a great beginner’s project from Red Reef Digital for those new to Node-RED. Node-RED is IBM’s browser-based, visual tool – looking just like a flow chart – for IoT programming. It seemed to come out of nowhere a couple of years ago, but it’s very easy to get your head around, and we’ve seen some... 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
- Henry Conklin’s dog, Oliver, is one of those very vocal dogs who likes to try to let you know what he’s thinking. By barking. A lot. Henry says: I decided that his thoughts and comments needed to be shared with the world. Thus the @OliverBarkBark project was born. By connecting a Rasberry Pi, a wifi... Continue reading
- Meet Miguel Wattson (geddit?), the most piscine member of the Raspberry Pi community. Miguel is an electric eel who lives in a tank at the Tennessee Aquarium; and his keepers, with some help from some computer science interns, have decided to use Miguel’s tendency to generate electricity to do some showboating. Electric eels (actually a... Continue reading
- Regular readers will remember that we featured Andy Proctor’s delivery lorry – hacked with a Raspberry Pi to become an Internet of Things delivery Andy lorry – back at the start of December. The BBC found out about him too, and he’s featuring on the front page of their news site today, with a really... Continue reading
- If you’re a keen follower of what we and the teachers we train get up to at Picademy, you might remember this little gem. (Not a lettuce. A video.) That Michael Jackson Tribute Glove (MJTG) was the work of Dan Aldred’s team (that’s Dan taking charge in the above video). When Picademy wrapped up, Dan said... Continue reading
- At Picademy, our awesome free training course for teachers, I run a workshop to introduce teachers to using the camera module with Python, and show them how to wire up a GPIO button they can use to trigger the camera. I always make a point of saying “now you know this, what can you make it... Continue reading
- UK teachers: want two days of free, top-class CPD? Check out Picademy, and send us your applications! What do you get if you cross a PiFace with a rubber dinosaur from Marks and Spencer? Twitter magic, that’s what. Teacher Dan Aldred has come up with a thing of beauty: a hack that makes your desktop... Continue reading
- So you’re at SXSW. And you want an up-to-the-minute cookie. What could be nicer than a customised Oreo, filled, flavoured and printed with the aid of a Raspberry Pi (in such a way that you can watch what’s happening yourself) all depending on what’s trending on Twitter at the moment? Our good friend Matt Richardson... Continue reading
- A guest post today: I’m just off a plane and can barely string a sentence together. Thanks so much to all the progressive maths teachers we met at the Wolfram conference in New York this week; we’re looking forward to finding out what your pupils do with Mathematica from now on! Over to Adam Kemény,... Continue reading
