  • Once you go down the retro gaming rabbit hole, that's it, you're not getting out without putting together your own gaming console. It all began with my hacked PSP, which I was running emulators on. Then I wanted to run them on my big screen. Unfortunately I have the first gen PSP that was sold in Australia, which means no chance of AV out. Then I discovered the Raspberry Pi 3B+, and everything went onto the big screen in a giffy.

  • I read somewhere about UNIX Epoch time and thought wouldn't it be neat to have a clock that showed time in this format? This project developed from that idea. I had a unused GPS module with serial output so I thought it would also be cool to use that for syncing the time and thus avoiding setting the clock manually. The final clock has the following features and characteristics: 16 digit 7-segment LED display Date/Time display

  • I was down at a local game shop recently and noticed their range of chess boards and decided to try my hand at a simple little project. I'm a big fan of Doctor Who, Chess and 3D Printing. So I decided to combine them all together into a fun project. Essentially, I set out to make a chess set based on Doctor Who using a 3D Printer, Laser cutter and admittedly a little DIY. I enlisted the help of Stephen from Core Electronics (see

  • Welcome to my project on how to make a very stylish lamp out of a potentially un-stylish material - concrete! To be honest, style (or rather beauty) is in the eye of the beholder and so I'll leave it up to you to decide if it fits in your surroundings or not. What do you think? All the necessary steps are here but if you don't like reading the just sit back, relax and watch the video instead. When I said to people at work that I

  • I used an Arduino and a US-100 ultrasonic sensor to make an extremely low-cost tide gauge. This project measures the tide by sensing the distance to water using a US-100 ultrasonic sensor. The device has a 3D printed base and uses a peanut butter jar to create a waterproof housing. The 3D printed base fits atop a PVC tube which acts as a stilling well to dampen wave effects. Timestamped data is logged to a mi

  • Our local council picks up recycling bins one week and green waste the following week. Sometimes people forget which bins go out each week and perhaps they mistakenly put the wrong bins out. Not that that has ever happened to me of course! I decided to put together a simple circuit and write a Python script for my Raspberry Pi to remind me whether it is recycling week or green waste week. A few LEDs, a resistor, a switch and a s

  • Hi all. Thought I'd share with you my modded Spirit Halloween proton pack. It's about 80% scale, which is plenty big enough for my 7-year-old son, and still looks decently sized on adults. As soon as I learned of this pack, 5-year-old me just had to get one. And I had just gotten my Arduino beginners kit a week earlier. I knew what had to be done :)

  • This project started life as an alarm clock for my son made to look like the time circuit from the Back to the Future movies. The display can show the time in various formats, including the one from the movies of course. It's configurable via the buttons on top of the enclosure but also via a web page served by the Raspberry Pi Zero inside. In one of the display modes it will show the local weather (from my Arduino-powered weathe

  • Imagine getting home from work, its winter, its cold. You have a shower to warm up and half way through your shower...... your water stops. You wrap a towel around yourself, remove the shampoo from your eyes and go out into the cold to swap the tanks as the water tank you were using had run dry. This was a common occurrence in my house......... but not anymore. Now I can keep visually see the level of water in my water tanks on m

  • I really love the reliability of my Fuji wireless mono laser printer. Best printer I've ever owned. However, it was released without Google Cloud Print. This required constant driver installation on new devices and the inconvenience of not being able to print documents until I am home. I had quite a few solutions in mind such as moving it near the router that could act as a print server. Too much effort ;) This is where the Rasp

  • The idea for this project came when a friend of mine flew over from Western Australia to visit, and during his stopover in Adelaide, he did what any adult would do; visit the airport novelty store and buy some random stuff. It was pretty much all junk, except for this big green dome button which played a different, comic voice saying ‘YES’ every time you pressed it. Simple, but, it entertained us on the drive from Syd

  • So, my wife wanted to have some small plants in the house. I didn’t, so we compromised, and got some plants. The only thing is that neither of us remembers to water them, so I wanted to build a sensor array to monitor the moisture content of the soil, and notify us when they needed watering. We’ve got 3 plants, all fairly close to each other, and I wanted to create an IoT project so that it could send an email notifi

  • UV is important to reptiles (and people) in processing vitamin D3 which is needed to absorb calcium. Without it reptiles often suffer from Metabolic Bone Disease (MBD) which leads to weak bones and can be fatal. Thankfully, pet shops have the answer, UV producing globes which can stave off the dreaded MBD. These are in the form of T8 florescent tubes or compact florescent globes and go for $50+ each. And, yeah, they need to be re

  • As part of a larger home automation project, I wanted the ability to control some mains power outlets remotely. To achieve this, I interfaced the transmitter from an inexpensive 433MHz mains remote control kit with a raspberry pi zero w (via a pair of 4066 chips). I then wrote a programme in C to which the desired channel is passed along with either an "on" or "off" command. I can now run a script from my smartphone which connect
