Digirule 2 & 2A

I have been fascinated with systems like the Altair 8800 for some time now and decided to up-the-anti with my second iteration of the Digirule by making a programmable binary computer built into a PCB ruler. The Digirule 2 and 2A are identical with respect to their hardware however the Digirule 2A comes pre-programmed with…

The Electronics Lab

The Electronics Lab is both a fun way to get started with building and programming electronics circuits and also to use a prototyping platform for your own creations. A series of instructional video’s will be provided to step you through various projects and circuits that are designed to make learning fun: many of the projects…

Electronics Fundamentals

This is a series of around 30 video tutorials that I have put together to help those just starting out with electronics. Most video’s have a multiple choice quiz so you can test your knowledge before progressing to the next video. There are around ten more quizes still to be uploaded and they will all…

You can purchase Retroball from my Tindie store: Unfortunately I have sold out of Retroball units – however you can still build your own since all of my projects are open source. Check out the download link at the bottom of this page for all the details you need to build your very own retroball!…

Electronics Course Notes

I wanted to build a nice easy to read, fun to explore electronics course. So I started making one – the only problem was that I didn’t really think about just how much time it would take me to make. As such I spent multiple months coming up with nearly 200 pages of content, but…

The Action Packed Adventure

While this post is not about any electronic project that I have made, it is nonetheless interesting (well, I think so anyway). The background story is that we are selling our house to move into a different house which needs some renovations done to it before we move in. We are trying to do all the renovations…

Brads Electronics Shop

I decided to open up my own little online electronics hobby store – Brads Electronics Shop (can you see how I came up with that name?) At the moment it is intended for those in Australia It’s now open to all those worldwide! to get all sorts of electronics components, tools, modules, wires etc… At a low price….

Another RetroBall!

I made a previous post of how some people have made their own RetroBall unit: https://www.bradsprojects.com/a-couple-more-retroballs/ Well it’s great to see that people are still making their own version and the latest addition has been made by forum user Ulf Maier. He has kindly provided some photo’s of his build which happens to be a super…

PCB Christmas Trees!

Forum user bitfogav has made a well themed project in the form of circuit board Christmas trees. Each tree contains 16 LED’s, driven by a couple of 74595 (serial in – parallel out) shift registers. An Arduino or practically any microcontroller can then be used to send in a bunch of 1’s and 0’s to…

The DigiRule

Digirules are available again from my Tindie store: Here’s a youtube video of the improved version: And now back to the original post… This project is completely open source. You can download all files including PCB layout, source code and BOM in the link at the bottom of this page. UPDATE: 30 December 2015 –…

StickyBUG – Make Your Own Arduino Shield

David John Barker (The guy behind my favourite programming IDE Swordfish Basic) has started up a Kickstarter campaign today where you can pledge for some StickyBUG’s! But what are StickyBUGs? Good question, but first some background information. Arduino is a great versatile electronics / programming platform that allows you to plug in various shields for…

Super Pixel Bros on the Intellivision

I am a big fan of the old Nintendo Entertainment System video game console. And perhaps one of my favourite games on that system is Super Mario Bros. (image reference: http://images.eurogamer.net/2013/usgamer/NGL1—Super-Mario-Bros.png) So a few years ago I decided to make my own version of this Nintendo classic but restrict it to just 64 pixels on an…

Tiny Screen: A color display the size of your thumb!

Tiny Screen is a small OLED display with a resolution of 96 x 64 pixels and a colour depth of 16bits which gives you 65,536 different colours. The display measures just 0.96″ diagonally which I guess makes sense as to why they call it tiny! The tiny screen is made by the same people that…
