More and more people are using a PC (conventional or notebook) to view films. The VGA output can be used to provide a matching ‘Ambilight’ effect for this. If you restrict your self to a sin... Read more
This simple circuit can be used to charge batteries from a solar cell array. The circuit consists of an oscillator, a DC-DC step-up or ‘boost’ converter and a regulator that provides regulat... Read more
Here’s a project that could be useful this summer on the beach, to stop anyone touching your things left on your beach towel while you’ve gone swimming; you might equally well use it at the... Read more
You’re doubtless familiar with the little solar-powered automatic lighting units found in DIY stores each year as summer approaches, sold in packs at ridiculously cheap prices. They certainl... Read more
As we all know, LEDs are dimmed by altering the current flowing through them, not the voltage. We achieve this effect in this circuit by using an AVR microcontroller (2313 from Atmel) operat... Read more
Here we couple LED oscillators together to produce some interesting effects for an exclusive optical touch to your robot. As seen in the circuit diagram in Figure 1, instead of using the dis... Read more
