This project is a miniature Audio CRO. For those not familiar with the abbreviation “CRO,” it means “Cathode Ray Oscilloscope” and this is sometimes shortened to “SCOPE or O-Scope.” A “CRO” is a piece of test equipment with a screen. It produces a visual indication of a waveform, via a probe, when the waveform is connected …
You’ll be the talk of the town when you wear this obnoxious, oversized, completely impractical wristwatch. Display your favourite foul language, song lyrics, prime numbers, etc. Inspired by the Microreader kit, I decided to make a giant watch using similar sixteen segment displays.

In the beginning, I just wanted to play with these cheap TFT screens available on eBay (displaying some pictures & text, nothing more); step by step, I finally designed a PCB and a built a consequent software with many …
Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instruct able is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs. Programming a big DIP (through hole) chip is easy. Pop it into a socketed programmer, burn, and return to the application circuit. …
I’m a fan of LEDs, lots of LEDs. So here’s a slightly less crass way of using LEDs for decorative purposes. While this is by no means a neat and polished solution, and probably not the first of its kind, however the pulse effect is as far as I have seen unique, and exactly what …
My obsession of this year is full-color LED. I have made Aurora 9×18 as a result. As much as I love the scale of Aurora 9×18, I also wanted to have something smaller, perhaps something that can go on a costume. Here’s Aurora mini 18. It has 18 full-color/RGB LEDs on a smallest possible circle. With …
