Machine learning, combustion engines and real-time control

What you’re about to watch in the video below is a magnificently physical example of machine learning. Adam Vaughan is controlling an engine with an adaptive Extreme Learning Machine algorithm on his Pi, which predicts homogeneous charge compression ignition (HCCI – if you’re  a petrolhead, you won’t have to look that up on Wikipedia like I did...

Cabe’s home arcade

I’ve got one of those rubbish Dance Dance Revolution mats at home for my PlayStation. You may have one yourself – they’re prone to skating all over the floor, wrinkling up at just the wrong moment and generally mucking your game up. And occasionally causing horrible injuries. Of course, with a little elbow grease and... Continue reading

Piano stairs

At a Princeton hackathon a while back, Bonnie Eisenman did something rather wonderful to a flight of stairs using a Raspberry Pi, some lights, an Arduino and a handful of photoresistors. Bonnie, I can’t believe you only won second prize. This is amazing. A while later, Bonnie made build instructions and code available on Instructables – and since... Continue reading

Royal Institution Christmas Lecture 1 – video!

As you’ll know if you’re a regular reader, we sponsored the Royal Institution’s 2014 Christmas Lectures. They have just made the video of the first of the Lectures – the one with all the Raspberry Pis in it – available to watch online, wherever you are in the world. It’s really worth your while – the...

Das Wordclock

We loved this project from Bernd Krolla – it’s beautiful, it’s useful, it taught him some stuff he didn’t know already – and it’s way, way cheaper than buying something like this ready-made in a store would be. This is not the first Wordclock we’ve seen, but it’s by far the most elegant, and it’s beautifully... Continue reading

Adafruit capacitive Christmas shenanigans

I got up late today; it’s Boxing day. And there in my inbox was a festive message from our friends in New York, PT and LadyAda, who found themselves at a loose end in the Adafruit factory on Christmas Day and took some video of a beta test they did for a new Raspberry Pi HAT... Continue reading

Royal Institution Christmas Lectures: sneak peek

As you’ll know if you’ve been reading recently, you’ll know we’re sponsoring this year’s Royal Institution Christmas Lectures. The lectures are broadcast this year on BBC4 at 8pm on December 29, 30 and 31 – and we’ve got a sneak peek for you today. First up, here’s a Tetris clone, being played on the side...

Naughty or Nice

I had the opportunity to play with this machine a few months ago, when Brian Corteil, a Cambridge maker-extraordinaire, brought it to a Raspberry Jam. It’s a piece of genius: the Naughty or Nice machine removes the guesswork from Santa’s assessment of the year’s behaviour, and applies the scientific method to the problem. A palm rested on...

Penguin Lifelines

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...

Christmas light sequencer

Over at Instructables, Osprey22 (what’s your real name, 22? Let us know and I’ll add it to this post) is driving audio and eight strands of lights (plus a jolly twinkly star) from the same Raspberry Pi, so the two can be sequenced using some custom Python he’s written. Play to the end for a bit... Continue reading
