2. Using Robot Kits to Explore the Possibilities of Technology and Electronics
October 17, 2012
When you speak to most electronics enthusiasts, their love for their subject is clear. Building electronics projects like robot kits is about more than simply making a model and watching it work. It’s about creation – about exploring the boundaries of what is possible, how it’s possible, and what yo...

3. Stepper-Motor in Modern Hobbyist Projects - Considerations of Size
October 14, 2012
A stepper-motor is often used in projects where robustness is required. The device’s simplicity ensures a good chance of it working even in some pretty hostile arenas – for example where dust or sand is present in quantity, or where there is a risk of water ingress into a project. It’s also relative...

7. The Theory That Makes the Gadgets Work - Electroluminescent Wire Explained
August 14, 2012
Electroluminescent wire works as a coaxial capacitor, flicking an alternating current between the phosphor coated core wire and the thinner wound strand of copper that is coiled around it. Capacitors, which used to be called condensers, are used to create an electrical field in which the circuit’...

8. The Stepper-Motor: What it Is, What it Does and How You Can Use It
August 14, 2012
A stepper-motor is basically a cog set inside a series of electromagnets. The electromagnets are fired one after the other, which makes the cog progress through a series of stages or steps. Each step is commonly used in an electronics project to denote a precise position of either an instrument o...

10. EL Wire Explained - What it Is, What it Does, How You Can Use It in Your Projects
August 14, 2012
EL wire is a very high efficiency source of electroluminescence. It’s basically a wire coated in phosphor with as second, much finer wire wrapped around it – together they form a coaxial capacitor. The efficiency of the circuit means that the wire can be powered for a very long time, at a very lo...
