welcome

We’re hoping that by the time this issue reaches you, the winter weather will finally be a thing of the past and warmer climes will be well underway. If that’s not the case, though, we have the perfect project to complete indoors and out of the wind and rain. It’s the first installment of a two-part series which shows you how to build a self-contained arcade machine out of old bits of kit, a spare Xbox pad and a Pi Zero! You’ll need to come back next month to discover how to load it with your favourite retro games. Other highlights this month include a handy way to power up your Pi by adding a battery pack and a way to print wirelessly to any printer on your network. Get inspired Discover the…

xbox zero arcade pt 1

The Raspberry Pi Zero is tiny, ridiculously tiny. It’s also small enough to be hidden in a variety of household objects in order to enhance their capabilities. Whatever you can find to fit it in, you can turn into some kind of smart machine. Take old game controllers. If you’re anything like us you’ve probably got a couple of boxes full of old computer equipment you just can’t bear to throw away – an Atari Jaguar that hasn’t been touched since the 90s, a Sega Dreamcast which you’re sure you’ll plug in again one day, an old Xbox that lies languishing since you picked up something bigger and better. Turns out it actually was useful to keep them around – it’s time to bring these old systems back to life. We’re going…

picture perfect pi

From alarm-clocks and to-do lists to calendar notifications and email reminders, do you sometimes get the feeling that you’re a slave to the machines? Peter Buczkowski has just taken the slavery to the next level. His Prosthetic Photographer ‘looks’ through a digital camera for interesting scenes and when it finds one, it jolts you with an electric shock, forcing your index finger to involuntarily trigger the camera’s shutter and snap the image. Ouch… lovely. What was the original inspiration behind the Prosthetic Photographer project? Prosthetic Photographer is part of my Master’s thesis in digital media. The topic I chose is ‘Experiments on human-computer interaction through electrical body part stimulation’. I discovered TENS units (transcutaneous electrical nerve stimulation) that people usually use for pain relief. One can also use them to stimulate specific nerves…

print wirelessly with your pi

Wireless printing has made it possible to print to devices stored in cupboards, sheds and remote rooms. You don’t have to own a shiny new printer for this to work; old printers without native wireless support don’t have to end up in the bin, thanks to the Raspberry Pi. The setup is simple. With your Pi set up with a wireless USB dongle, you connect your printer to a spare USB port on the computer. With Samba and CUPS (Common Unix Printing System) installed on the Raspberry Pi, all that is left to do is connect to the wireless printer from your desktop computer, install the appropriate driver and start printing. CUPS gives the Raspberry Pi a browser-based admin screen that can be viewed from any device on your network, enabling complete…

add a battery pack to your raspberry pi

Your Raspberry Pi’s mobility is usually restricted by the length of the power lead. Rather than limiting it to your desk or living room, however, you can use it for mobile projects as diverse as launching it into near-Earth orbit or monitoring and automating your garden. Of course, to do this you will need batteries, but adding battery power to your Raspberry Pi is simpler than you might have imagined. All that is required are six rechargeable AA batteries (or single-charge alkaline), a battery box with space for the batteries and a UBEC. The latter is a Universal Battery Elimination Circuit, a voltage regulator that will regulate the power supply and prevent damage to the Raspberry Pi, and can be bought for under £10. 01 Make your order If you’re buying your components…

control your pi with pylci

pyLCI is a simple hardware interface you can use on your Pi to control and configure it without the usual requirement of having a HDMI monitor, Ethernet connection or a connecting a USB-UART dongle. Mainly, it enables you quickly configure the most important settings, such as connecting the Pi to a wired or wireless network and getting its IP address. This makes your Pi accessible – whether you are in the comfort of your home, somewhere outdoors, or maybe even working with your Pi on a long bus ride! All you need is a simple shield with a character display (16x2, for instance) and some buttons; there are many suitable shields which you can get, some of them as cheap as £5. pyLCI stands for ‘Python-based Linux Control Interface’ and it’s a…
