How to Develop Photonic Products for Fun and Profit

You think those new processors such as the Pentium and Alpha are fast? Ever consider a light-based computer? It may not be long before you SEE one of these.


Shaun Greaney

In the Eye of the Beholder

Displaying Messages with the LightStick II

If you've ever seen multiple images of the current time as you sweep your eye past a digital clock, you've experienced the premise behind the LightStick II. Find out how to display your own ghostly images.

Interrupt-free Design

Over the years, the purpose behind a design decision is often forgotten in a sea of, "But that's the way we've always done it." If you automatically use interrupts in your embedded designs, think again.


Hank Wallace

An Assembly Language Programming Aid

Even though it may seem everyone has switched to high-level languages, experienced programmers know the value of hand-crafted assembly code. Here's one technique that combines the best of both worlds.


Ed Nisley

Firmware Furnace

Hardware for the '386SX Project's Bitmapped LCD Panel
