Christmas Tree LED Display

The motivation behind this project was so that I could give a simple little gift to friends, family and neighbours that was unique (and inexpensive!) This little device measures just 3cm x 3cm x 2cm and is designed to hang on your Christmas tree just like any other ornament. When you switch it on, it…

The Game of Reaction

Reaction is quite a simple little game whereby you have to press a push button as quick as you can when the LED changes from RED to GREEN. The faster your reaction time the lower the number that will be displayed on the seven segment display.   All the credit for this idea came from DJSPANKY one…

The 8×8 Game System

I was selling these as a build it yourself kit but unfortunately I have run out. You can however build your own with all the information contained within this web page. You can download schematics, parts list and there are a number of games to try out also. Original Demo Video: Space Invaders Game: Stacy’s…

The LEDBOY Handheld Game System

This was my second attempt at making simple video games within a 64 pixel display. This time however, I used an RGB LED display rather than just an RG display. The circuit design is quite similar to the old 8×8 Game System, just a little more expanded. I quite enjoy the old retro video games…

ADC using a digital port pin.

The idea for experimenting with Analog to digital conversion came from an old Atari game – Grand Prix. The game was played with an analogue controller where you could twist the controller clockwise or anti-clockwise to guide the car through the race track. The car’s position is relative to where the controller is positioned which…

32×64 Pixel Spinning RGB POV Display

Unfortunately this project did not work out as well as I had planned. I could not get it to do animations. It would happily display one individual frame but when I wanted it to scroll through a number of frames, I ran into all sorts of problems. Having said that, I did come up with…

The Great Race

The great race is a very addictive and easy to build little game. It is made from readily available and inexpensive components and was actually the first game I designed with a microcontroller. The idea of the game is to drive your car (the red dot) to the left and right of screen to avoid…

8×85 Pixel RGB Spinning POV Display

This was my first attempt at an RGB LED POV Display.  POV stands for persistence of vision. This type of project works with our eyes relatively ‘slow’ refresh rate. When we flash some LED’s with certain information and then spin those LED’s, our eyes don’t see the fast flashes, but rather sees a complete picture…

Super Pixel Bros

This game is based on the 1985 Nintendo classic – Super Mario Bros. Super Mario Bros is one of my all time favourite games. I liked it so much in fact that I decided to make my own version, but restricting the graphics to just 64 pixels! I have given it the name ”Super Pixel Bros”…

BJT Biasings for iOS

Please note – I stopped paying my Apple developer subscription and as such, this app is no longer available for download. This is an iOS app that I originally made to help students in my electronics classes to better understand the inner workings of various BJT circuits. I will often ask the students “What will happen…

The PICnDuino

The PICnDuino is an Open Source dual microcontroller development platform built into a tiny direct to USB device. It is compatible with both Arduino and Amicus18 which have an already established fan base giving you instant access to hundreds of tutorials, code examples, project designs and support forums. For the more adventurous users, you can even use…

Microcontroller Oscillator Experiments

Tonight I decided to do a few experiments with an 18F2550 and PLL settings to see exactly what effect it would have on the operation of the microcontroller. More specifically, I just wanted to fix firmly in my head what the data sheet was telling me and also to see how long an instruction took…

Gameboy to VGA Converter (In Progress)

I made mention a few weeks ago in the forum that I was working on some VGA experiments. Well, I decided to see if I could get an old Nintendo Gameboy from 1989 working on a VGA monitor. This page documents my experiments and progress in achieving this goal. As I make more progress, I…
