ESP32-CAM QR Code Scanner
This project combines two separate projects to get a system that acts as a WiFi Access point and web server to display QR codes scanned with an attached camera module.
Hand drawing to laser cutting with Inkscape
A quick overview of the workflow to get a hand-drawn part laser cut using Inkscape.
Creating custom monochrome graphics for micro-controller screens
Arduino code Converting images into byte arrays for mono-colour screens with microcontrollers. Best suited for static splash screens or basic animation on small screen sizes when using the Adafruit_GFX library with Arduino.
E-Bike Lighting system WIP
Work in progress!
This is a long term project of mine for my E-Bike a lighting system with headlight, taillight, indicators, alert system/horn/bell, and a control switch pad.
Solar powered WiFi weather station with Google sheets upload
This project uses spare solar panels and an ESP-01 DHT11 module to gather weather data and upload it to a google spreadsheet.
Brilliant Smart WiFi plug
These smart plugs are a readily available, low-cost, and non-invasive home automation solution. Some models also have power monitoring.

DIY Arduino Robot Arm with Smartphone Control
Hey peeps, Steve here 😀
Here’s a side project I’m working on in the Design FabLab to learn how to use mechanical electronics, Arduino microcontrollers and coding.
A pretty big endeavour for me as I don’t have much background in this stuff but thankfully I’ve found a great tutorial that I will be following along with to start with, then deviating and customising parts and coding later when I fully understand the workings of the default example.
Here’s a link to the website and tutorial – https://howtomechatronics.com/tutorials/arduino/diy-arduino-robot-arm-with-smartphone-control/
Below is a photo of the assembled 3D printed parts with the servo motors installed.
At this point the arm doesn’t do anything and won’t support it’s own weight but I will be working on the electronics soon enough and powering it up!
If you want to see more or get involved, maybe build one too, come and have a chat 🙂
Awesome and handy project links available on the web.
Building a tilt control bluetooth car with processing and arduino
Remote Control Car
This project makes use of an Arduino, a car chassis, a bluetooth module, and an android phone to make a Remote Control Car that is controlled by tilting the phone like a steering wheel. This post is a high level overview of the project and requires a solid understanding of coding.
Router base insert replacement
This part was a replacement and particularly tricky as it had some tight tolerances. It was made with CAD design, Laser cutting and CNC milling.
Engraving onto metals with a CO2 laser
STM32 (“Blue Pill”) Arduino programming
This will show you the way to program an STM32F1xx series microcontroller with the Arduino IDE (integrated development environment).
RFID and Arduino
This is a basic access control project to read and use the unique IDs of RFID cards including the University of Auckland ID cards.
It uses an RFIDRC522 module that can read 13.56MHz cards and the code is based on the RC522 Arduino library found HERE. It can also write data to the sectors of blank types of these cards for offline data storage or counting, but for this project, we will just be reading the ID numbers of the cards.
Interfacing Arduino and sensors with Unity
For this project, we attempted to interface hardware sensors with Unity to manipulate virtual objects and give feedback to hardware.
Goals for this project; To use a sensor to control the camera position in a basic Unity 3D scene, and to turn on and off a LED, based on keyboard inputs.
This is based off a YouTube tutorial by inScope Studios.

Arduino Radar scanner
This uses Arduino and hardware to feed data into Processing for the graphical user interface.
