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.
Indesign Helpful Hints
Here are some useful hints we have used with our own projects:
Overview of 3D printing processes
A collection of 3D printing process explanation videos
Hand drawing to laser cutting with Inkscape
A quick overview of the workflow to get a hand-drawn part laser cut using Inkscape.
Spatial computing lab – Conference use
In the 2020 Christmas break, the design lab was set up into its film studio configuration to help the universities events team to host the APRU Sustainable Cities and Landscapes Conference online.
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.
Illustrator scripts
A repo for custom Illustrator scripts
Electric tooth brush holder
This project was to create a nice way of holding toothbrush heads for my electric toothbrush.
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.

Electronics Basics
This brief tutorial gives some tips for working with electronic circuits and covers some common issues beginners can have.
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.
Creating professional pinout diagrams
This is a great tutorial from Adafruit showing how to create professional pinout/wiring diagrams with free vector software Inkscape. It could also be transferred over to Illustrator.
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.

ESP32 Links
Awesome and handy project links available on the web.
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.
Handy Arduino boards & libraries

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.
Complex 3D objects to 2D profiles
After a lot of researching here is a free way to create a 2D cut profile from a 3d surface.

Interfacing Arduino and sensors with Unity
Overview
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.
Files used are available at the end of this post.
Arduino Radar scanner
This uses Arduino and hardware to feed data into Processing for the graphical user interface.
