Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

The project we're going to be working on is a simple Morse code flasher, but rather than using a buzzer - which is sure to get on the nerves of anyone in your immediate vicinity - we'll be using an ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance Stage.

Ynformatic has this week published details on how to use your iPhone together with a little Arduino hardware and programming to create some awesome polarised images similar to the one above. The ...
