empowering creative people

The "Project" is what compels makers to learn, design and create! We're all about electronics projects here at Core Electronics and have made it as easy as possible for other makers to share their projects with us and the broader community. Every project listed here was built by our community of electronics enthusiasts and include desk gadgets, practical solutions for around the home, or widgets built for no other reason than "just because” (often the most fun kind of project!)

Share your project today and get rewarded with a minimum $50 store credit. Yep, you read right!

FYI, the projects module is brand new, even more reason to get involved and share your project as we'd love to see a wall of great builds below!

  • I bought a Pi zero w from Core Electronics for a friend, also bought the official case too but thought I'd fit the Pi into something he can show off! I used an old hand held game case I had laying around, I had to remove the original circuit board and plan where to place the Pi board.

  • This is an awesome project that takes about 6 hours to complete. Hours upon hours of endless fun thereafter! Ideally, some prior soldering experience is advantageous but if you take your time and practice before you start it's beginner friendly! The battery will give just over 3 hours on a single charge and can be recharged via the handy micro USB port. System updates, ROM transfers etc all possible with the Pi Zero W' built in

  • Now that we have decked out our Lulzbot Taz 6 3D Printer with a really nice looking acrylic enclosure, I'm just about ready to turn on some serious 3D printing work. But before I dive into that endless pool of fun, it's a good time to take 5 minutes and set up our Taz 6 and it's OctoPrint Server with a bed-mounted camera and light system. That way I can monitor my prints from the other side of the warehouse using OctoPrint, and m

  • 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

  • For $50 and some dedication a retro gaming console can be yours and with HDMI you can play it with any modern TV or monitor. Instead of using bulky and space taking cartridges and discs it's all on the console. For this build, we're going to use Retropie, an awesome software package that handles all your emulation needs with inbuilt Bluetooth and wireless needs. Any Pi can run RetroPie, but I recommend using the Raspberry Pi Ze

  • 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

  • Who says you can't have it all? Good looks and a great sound! My name is 'Holman" and I'm a Bluetooth speaker in the form of mans best friend - a dog of course! Why is my name Holman? Well, that's the name of the manufacturer of the PVC pipe I used and the name grew on me as I completed the project! Whilst this might look like a complex project if you have access to the metric PVC pipe and a 3D printer I'm actually quite easy t

  • 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

  • YAM (or YetAnotherMonitor) I keep more than 20 enclosures of Australian native lizards and turtles and I want to make sure they are all in an appropriate environment. To that end, I built a microcontroller-based system to monitor the temperature and water flow rates for each tank, showing me up to date information and time trends from the convenience of my phone, tablet or PC.

  • I made a Raspberry Pi camera that captures GIF files and optionally tweets them over WiFi! It's built around a Raspberry Pi Zero W and a Pi Camera module. The camera connects to a pre-programmed WiFi network to tweet the gifs, but you can also retrieve them from a shared folder if you have another computer on that network. Take your snaps outside with diffuse light for best results. Here's me mucking around in our ca

  • We've built a mass SD card writer using a Raspberry Pi 3 Model B, some USB hubs and SD card readers. This beast has enough ports to write 49 SD cards at once! At Core Electronics, sometimes logistics hang-ups mean that suppliers cannot meet our demand for pre-flashed SD cards. During these periods we have to pick up the slack by manually imaging blank SD cards we source ourselves. Of course, this is a super-tedious process, and

  • This project is about how to build an 8 bit computer on breadboards, from 7400 series basic TTL. I am currently in the process of building mine, and will give an overview of what's involved. It is a great project that can teach you a lot about how a computer works at a basic level, and it allows for adaptations and expansion to your own interest. The computer will be able to perform basic programs such as computing the Fibonacci

  • I recently picked up a used BMW E46 and noticed the door panel trims were all hanging on by some duct tape. When I went to inspect, I noticed that all the clips had been broken and replaced with silicone rubber to try and hold it to the door. With some CAD and 3d Printing, I set out to replace them all and restore my door panels to their former glory.

  • I used to sleep in a caravan on my grandparent's property and as amenities were inside the house I had to go in and out of it quite regularly. I got sick of fumbling around with keys to go in and out of my caravan, so this project uses an Arduino Micro, 3x4 keypad, LCD and an electric door strike to unlock the caravan door.

  • We've got a whole bunch of Raspberry Pi 3 Cases here at Core Electronics. From the Official Enclosure that's perfect for most uses, right through to the gilded PiBow Coupe from Pimoroni. All of the cases we see have one or two impressive features, but our problem was that none of them ticked all the boxes when it came to a case. We've set out to create our own case, using our Raspberry Pi Expert - Sam as the tester. We are going

  • In preparation for some Maker Faire's we were heading to last year, I wanted to combine the awesomeness of the Makey Makey platform, with the fun that is RetroPie. For those who don't know the Makey Makey, it's a fantastic platform that allows you to connect the pin of an Atmega32u4 microcontroller up to the world around you. Fruit, vegetables, people, graphite, play dough, anything as long as it's somewhat conductive. It then ou

  • Wands are cool, right? That's what Trinity, Adele, and April were thinking of our recent littleBits Workshop, down at the Core Electronics Knowledge Factory. Their inspiration for this project came straight from the films, in particular, the magic wands that Harry and co use throughout the Saga. They went a bit above a typical wand though, using a pressure sensor alongside a fan, buzzer, and bar graph to make their wand light up

  • A couple of years ago, I found a modern jukebox (with iPod connectivity, AM/FM radio, CD player and LEDs) dumped in my street. The body was in decent condition but all of the electronics were ruined apart from the LEDs. I decided to take it and replace all of the electronics with my own and add a few cool features. One of the parts of the larger project was to make an FM radio with an LCD and pushbuttons to control the frequency

  • Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h

  • We wanted to make a interactive display of the fun that can be had with DIY projects to take to Sydney Mini Maker Faire. We decided to do so by utilising the TinkerKit Braccio from Arduino.org, alongside some 3D Printing ingenuity, for an engaging display for all ages. Enter the Hipster Coaster in all its glory. All the parts were printed seperately on our family of Lulzbot 3D Printers, later stuck together using a mi

  • The driver behind this project is to allow the remote control of some of the equipment in my shed. I have a CNC router/laser cutter that uses my compressor and dust extractor whilst it is running, and well whats the point in having a computer comtrolled machine if you have to hang around and turn the other auxiliary bits on and off?!? There are a million ways to skin a cat, and the same is true about this project. However after

  • This project began as an experiment when I inexplicably decided to learn how an optical rotary encoder worked (FYI, 2-bit gray code). It transformed into a learning experience around USB - specifically the HID protocol. Ultimately I ended up with a simple gadget that now sits on my desk and allows me to control the PC volume. A salvaged optical encoder was used to detect rotation along with a reclaimed head drum of a VCR which wa

  • These days we can do just about anything on our phone, we can control so many aspects of our lives using the technology in our pocket, but the most mundane aspects of our lives; opening the garage door, blindly reaching for the light switch in the dark, opening the front door when we get home, still relies on manual interaction. So I created the Particle IoT House, which contains servo motors to open and close the front and gara

  • I’ve had a Current Cost Power Monitor for a number of years which worked well until we put solar on the roof. The Current Cost can’t determine which direction the power is flowing and so power generation and consumption are added together on the Current Cost display rendering it unusable. The solution I came up with is actually two projects that communicate via RF. Arduino Yun connects to the Current Cost via the
