welcome

Between doing all the coding and hacking the hardware, working on a Raspberry Pi project can sometimes leave you feeling overwhelmed. Well, this month’s main feature is here to offer a helping hand – in the form of a robotic arm. Read on to find out how to build and program this gadget, which can pick up and move items up to 100g in weight. If you’re still in need of extra assistance, this month we’ll also show you to how to use your microcomputer to find your missing phone and program a calendar to keep track of all of your family member’s birthdays. Our experts also solve many of your project problems in our Talking Pi section. If you have a similar Pi query, don’t forget you can always reach…

control a robot arm

This tutorial combines the Maplin Robotic Arm and Pimoroni’s Skywriter HAT so you can take control of the robot with just the touch of your fingertips. The arm can move through three points of articulation and ends in a clamp to give you maximum flexibility with movement. The arm also moves through 120 degrees in the wrist, 300 degrees at the elbow, 180 degrees at the base in the vertical and 270 degrees in the horizontal. It is easy to assemble and is a great beginners’ robot. In this tutorial you will first install the Python modules to enable your Raspberry Pi to interact with the USB port, and then learn how to use Python code to send commands to and receive them from the arm. Next we’ll write a…

raspberry pi air drum kit

Where did the original idea for the drum kit stem from? What’s always interesting to me is where we find our sources of inspiration. These can be a person, a book, a tweet, a website – anything at all. A lot of my project ideas start when I find something at the local car boot sale. This time what I found was an Air Play ‘Air Drum’ – being offered for the grand sum of £1! How could I possibly refuse? So I took it home and had a quick play and to be honest, while the concept is great, the actual functionality was a bit limited, the sound quality was rubbish and it was also a bit suspect as to what sound played with what movements. How was the build process? Did…

use your raspberry pi to find and track your phone

The Raspberry Pi model 3 saw the introduction of embedded Wi-Fi and Bluetooth capabilities. This now makes it even easier to interact with Bluetooth-enabled devices such as mobile phones, tablets and speakers. The Python programming language supports a range of libraries that enable you to interact, monitor and control various elements of a Bluetooth device. This tutorial combines the Pi’s Bluetooth hardware with Python code to create three simple but useful programs. First, build a short program to search for Bluetooth-enabled devices and return the 12-part address of each device. Once you have obtained the addresses, you can then scan and find Bluetooth services that are available on that particular device. Finally, use the Bluetooth address and some conditions to check which devices are present in a building and in…

hack a toy with the raspberry pi: part two

In part one of this tutorial (see RasPi issue 34) you created four hacks that were originally used to augment a £3 R2D2 sweet dispenser making it light up, vibrate, play music and stream a live web feed to a mobile device. You may have been working on your own features to use and customise your toy. Part two of this tutorial begins by showing two different ways to set up and use a button to trigger your hacks. One method is to add and code your own button, the second method is to utilise the toy’s own built-in button. The next part walks you through how to wire up, code and test each of the individual features before combining them into a single program which will bring your toy…

take night shots with the noir camera

Want to get more out of your Raspberry Pi’s photographic abilities? You might have already connected a webcam or the official camera module, but found that certain activities – particularly shooting in low light – have been unsuccessful. The solution is a new camera module, the Raspberry Pi NoIR Camera Board, which has no infrared filter. This makes the camera ideal for taking infrared photographs or photographing objects in low light (you still won’t be able to take photos in the dark without a light source). Capable of delivering 5MP still images, or recording video at 1080p and 30fps, the NoIR camera is easy to install - but for the best results, use with a case and portable power supply. 01 Check your contents When you receive the Raspberry Pi NoIR Camera…
