Thanks to Aaroncake’s electronic circuits, we bring you the mighty strobe light.

Aaron, who works as a computer technician, has an extensive collection of gadgets on his site, ranging from the small and inexpensive such as the LED chaser, to the slightly more advanced and intricate, such as the computerised home.

For those musically inclined design engineers, we present the keyboard hooked up to a tesla coil.

If there’s one thing we hate more than track work on the Victoria line, it’s not being able to hear the damn phone when it’s ringing.

That's why he created a 40-LED night light to make sure he could see and be seen on his bike. Bill set up a 555 timer IC to generate a continuous on/off timing cycle to alternatively flash two groups of 20 LEDs. His night light operates on four AA batteries, which will keep the road ahead nice and bright, even on the darkest and chilliest of British nights. You can even extend battery life with a second circuit Bill put together that uses a short duty cycle to flash a single set of 30 LEDs.

Here’s a great little circuit that will ensure that electronics engineers the world over will have one of the coolest apartments on the block.

From Alan Parekh’s tome of knowledge, comes the stair lighting kit.

And now for a way to bring some friendly Poltergeist activity to your very own home.

Driving with high-beam headlights will ensure your visibility in the coming winter months, but they’ll blind any driver who’s coming from the other direction.

Any owner of a model train will tell you that the toy’s head lights are, at best, inconsistent and, at worst, terribly ineffective.

Why is that you always test 48 bulbs before you find the bad one in a 50-light string?
