4Borg robot review

4Borg robot review

We’re very excited about this one. For a long time, any other Raspberry Pi robot has seemed to pale in comparison with anything put together by the PiBorg team. It’s never really been a fair comparison, of course; a lot of Pi robots are made for those on a budget, and so focus on making a first foray into robotics inexpensive. Not all the PiBorg robots are kits to begin with, so when the monstrous…

Surfing Random Streams

Surfing Random Streams

Back in part four of the series (The MagPi issue 39), we looked at randomisation while coding some sizzling synth riffs. Since randomisation is an important part of my live-coding DJ sets, we thought it would be useful to cover the fundamentals in detail. So get your lucky hat on; let’s surf some random streams! The full article can be found in Sonic Pi Essentials along with even more Sonic Pi tut…

Balance bot

Balance bot

There’s a reason a lot of robots don’t use two wheels or two legs: very simply, it’s difficult for them to balance. It’s much easier and sturdier to be on three (or more) wheels or four (or more) legs; generally, just having a low centre of gravity is a good thing. For two wheels in particular, you need some way of maintaining balance. Usually, this task is left up to humans; as Kris Temmerman sho…

MeArm robot kit review

MeArm robot kit review

As a kid, it was weird coming to the realisation that the only real robots were robot arms. This was only really for a period in the Nineties, though, and probably not true; from the perspective of a child, however, that was how it seemed. Proper automatons, both expensive bipeds and cheaper wheely-trundly types, are now far more common than they were. The MeArm, then, is a bit of a nice break fro…

Make your own Pi HAT

Make your own Pi HAT

HATs first arrived with the launch of the Raspberry Pi Model B+ in 2014. Since then, there have been some amazing and wonderful HATs, many of which have featured in previous issues of The MagPi: theUnicorn HAT, Piano HAT, Sense HAT, and Explorer HAT. Officially, HAT stands for ‘Hardware Attached on Top,’ although your expert suspects that the acronym came after the name. What else would you call a…

Sniffur – dog tracker

Sniffur – dog tracker

We love animals here at The MagPi, so when we heard about a Raspberry Pi dog-tracker called ‘Sniffur’, we had to learn more. Sniffur uses tracking technology called ‘beacons’; these are relatively new devices being placed in department stores to track the precise location of customers. The full article can be found in The MagPi 42 and was written by Lucy Hattersley Sniffur flips this idea on its h…

LCD Control Case review

LCD Control Case review

We reviewed the SPI-Box from SB Components recently, a custom case for the Raspberry Pi 2 and B+ (although it would probably fit a Pi 3 just fine) that allows for a motion sensor and a Pi Camera Module to poke out of the case. With the bundled software, this means you have a functional and cheap security camera, with plenty of software bells and whistles to make it genuinely useful. Using a simila…

Tweet from Raspberry Pi with Wolfram

Tweet from Raspberry Pi with Wolfram

The Wolfram Language is a powerful knowledge-based language that makes computation accessible to everyone, and is an easy language to dip your toes into as a first-time programmer. To send tweets from Twitter on your Raspberry Pi, all you need is a single function. We’ll be using SendMessage, which is a multipurpose function in the Wolfram Language that gives Raspberry Pi users the ability to seam…

Strato Pi makes Raspberry Pi more professional

Strato Pi makes Raspberry Pi more professional

At the launch event for the Raspberry Pi 3, Eben Upton revealed that there were plenty of industry customers for the Raspberry Pi, making up a significant percentage of those who have contributed to the eight million total of Raspberry Pis sold. Recently, Sfera Labs has launched a new line of Raspberry Pi add-on boards called Strato Pi designed for the professional applications these Pis are being…

Location-tracking mountain model project

Location-tracking mountain model project

An LED lights up on a scale model placed on a kitchen counter in Washington State, USA, to signify that over 9,000 miles away in Tanzania, Kurt Hunter has reached the summit of Mount Kilimanjaro. Climbing Africa’s highest peak had been a long-held ambition for Kurt. “Ever since moving to Seattle 20 years ago, I would look up at Mount Rainier and dream of climbing it,” he tells us. “After getting m…
