Getting the Nvidia Jetson TX2 working with the Auvidea J130 Carrier Board

Auvidea make some pretty cool carrier boards for the Nvidia Jetson series of computers. The J130 is particularly powerful for machine vision applications due to the 5 USB3 ports available. I recently got my hands on one from mouser in addition to a Nvidia Jetson TX2i module and ran into some issues initially. These included: …

ESPCaptiveImagePortal: A Captive Portal That Displays Images

I hate the internet. I hate it not only because it shows us the decay of society in real-time, but also because I do not really understand it. So I came up with a concept for a gift that attempts to satirise not only the way people use the internet to dish out their unqualified opinion, but also the shallow way in which people deliver that opinion…

ESPFlash: An Arduino Library for Storing Data in the ESP Filesystem

27/12/2022 UPDATE: I have finally managed to fix a few annoying bugs with this library and release a new version. Hopefully it continues to get some use out there! SPIFFS (or SPI Flash File System) is very cool. It is an Open Source Library intended for SPI NOR flash devices on embedded targets. Embedded targets …

ESPStringTemplate: An Arduino Library for Building Web Pages

I recently began a project where I needed to build some dead simple, HTML only static web pages during runtime with the ESP8266 to represent data stored on the filesystem. Depending on the number of files located on the filesystem various buttons, forms, and text needed to be generated. In addition I needed some templating …

Setup Guide for SEGGER J-Link and SystemView with STM32 Nucleo Boards

SEGGER SystemView is a very cool graphical tool for embedded systems that enables the┬ávisualisation of┬árun-time behaviour in an application by the recording on configurable events. These events can be recorded using J-Link, IP, or UART communication. A huge plus for using SystemView is that it is totally free to use, provided that in one event …

A High Speed High Current LED Driver; Refurbishing ACMI’s Zoetrope

One of the more popular exhibits in Screen Worlds at the ACMI is The Zoetrope. Like all exhibits inside of Screen Worlds, the Zoetrope has not aged gracefully due to over 9 years of active service! With the original design utilising xenon based strobe lights, the maintenance cost of this exhibit in man hours and …

The Parametric Digital Transducer Array Loudspeaker

For my capstone project that I completed at RMIT University I conducted a bunch of research into experimental loudspeaker designs such as Digital and Parametric Loudspeaker Arrays. As a result of this project I conceptalised a design for the Parametric Digital Transducer Array Loudspeaker, built a prototype, and validated the design by performing a variety ...

A Magnavox Odyssey Pong Clone Using Arduino

The Australian Centre for the Moving Image, or ACMI as it is more commonly called was home to the permanent exhibition Screen Worlds before it’s recent refurbishment took place. The exhibition was first opened all the way back in 2009, and has a large range of exhibits that showcase different technologies and trends in film, …
