Welcome to Issue 22 of The MagPi magazine. We kick off this month’s issue with an article on solar tracking. Nathan and Nicholas introduce their amazing project, the ‘Reflective Solar Tracker’, a solar cell with the brains of a Raspberry Pi, capable of chasing the sun to improve energy capture by up to 140%! Andy Baker returns following his successful quad-copter series and this time he is featuring his intelligent night light. Andy describes building this project to reassure his son at night and banish those ‘under-bed monsters’. It’s a great mix of both the PiBow case and PiGlow add on-board.
untitledThe aim of this exercise is to show students how to the Raspberry Pi may be used in conjunction with a L293D chip to control the direction of rotation a DC motor, and how the speed of a DC motor may be controlled using Pulse Width Modulation (PWM). The exercise will also demonstrate how a simple human machine interface can be programmed to control the system in various different ways. Learning ObjectivesTime-lapse Photography with the Raspberry Pi CameraA simple time-lapse photography project using the new Raspberry Pi Camera with a Raspberry Pi Model A and a battery pack. I'd long wanted to try my hand at time-lapse photography and for one reason or another had never got round to doing anything about it, but when I was fortunate enough to be given a pre-production Raspberry Pi camera I no longer had any excuse! Configuring Raspbian Since network access was required for software configuration this was carried out using a Raspberry Pi Model B, although a Model A could have been used with a USB network adapter.
Dr. Bunsen / Building A Weather StationSummary This post describes a project I created to solve several problems I had with weather. The project is comprised of weather sensors, monitoring hardware, and a webapp I built. The webapp manages weather data streaming from instrumentation I have setup at my house. These tools allow me to monitor the current weather conditions, visualize salient data, and receive custom alerts when certain anomalies are detected by my sensors. Here is a picture of my weather station serving data to a consumer running in my office:
Raspbian flavor: RaspRazorOkay, this time it works almost perfectly for me. I like the the configuration menu where you can choose to enable SSH, etc. Still two minor issues though: 1. Now every time it boots it gives a warning on mount point '/squashfs' not exist.2.Programming Raspberry PiNearly all of the fuss about the low-cost Raspberry Pi computer's hardware has died down and we finally have some details of its software that is easy enough for the rest of us to follow. So what can you do with it out of the box? Dr Eben Upton, founder of the Raspberry Pi Foundation, has just posted some easy-to-follow details of how to get started programming the Raspberry Pi.Remotely Accessing the Raspberry Pi via SSH – Console ModeRemotely Accessing the Raspberry Pi via SSH – Console Mode This guide will walk you through the steps to logging into your Raspberry Pi's console from another PC or laptop. The method utilises Secure Shell (SSH), a secure network protocol for data communication, which is very useful for remote operation via command-line.
Adapt your Raspberry Pi Camera for close-up useThe Raspberry Pi Camera is a fixed focus module, so that anything from about 0.5m to infinity is acceptably sharp. This has strengths and weaknesses, as with every design decision. The weakness in this case is that if you want to film or photograph anything closer than about 50-75cm it will be out of focus.How to Crowdsource Your Wedding Photos with Instagram A Practical Wedding: Blog Ideas for the Modern Wedding, Plus MarriageIt’s crazy to think how much technology has changed the way we interact with our weddings. I’ve only been married a few short years, but thanks to iPhones and…well, let’s face it, iPhones, the landscape now is completely different than it was then. In some ways this is not so great (ever been to a wedding where the guests spent more time recording the ceremony than experiencing it?) and in other ways, it’s kind of awesome. In the time since we ran our first ever How To DIY Your Wedding Photography post, advancements in technology and user-friendly social media platforms have made wedding photography even more accessible than ever.
