Current Project
At the moment, I’m devoting all of my time to building, testing and documenting a home-made LiDAR scanner for my college project.
Project Progress Feed
Progress will be slow, painful and most likely wrong. The feed below documents some of my trials and tribulations.
Casting Lead Using a Lost-PLA Process
Do you ever wish your 3D prints had x22 times more mass? Has the lack of toxicity in your 3D prints been a source of …
Testing Video Transmission with Various nRF24L01 modules
As eluded in the resource page about sending video wirelessly via a pair of nRF24L01 transceivers, I wanted to do some range & speed tests …
Using an OLED I2C Display with 433MHz RF Modules
While working with the 433MHz RF transmitter/receiver pair, I found an issue when trying to integrate a SH1106 OLED display module into the system. This …
Reva G-Wiz: A New Project
I've always wanted to build my own car: the idea of driving something unique as well as having total control of the specification appeals to …
ESP32CAM – Digital Panning using a Joystick and ST7789 Display.
As with most ideas, this one came at the inconvenient time of 11:13pm – so I sent a Whatsapp message to myself to remind me …
An Exercise in Futility: Edge detection on a ST7920 128×64 LCD display
Ever since doing the successful real-time edge detection experiment using the GC9A01 display, I couldn't help but wonder what it would be like on the …
Real Time Edge Detection using ESP32-CAM
This project builds on the experience gained during the previous motion tracking ESP32-CAM project, and is simply just a proof-of-concept to see if the ESP32 …
ESP32-CAM Realtime Motion Tracking: First Tests
After finding myself with a little extra time over the festive period, I decided to go back over the ESP32-CAM homebrew computer vision project after …
Comparing the Garmin LiDAR-Lite V3HP with the Benewake TF-Luna LiDAR sensor.
I've previously tested beam divergence of the Benewake TF-Luna as part of the VL6180X distance sensor write-up, which also includes results from the Sharp IR …
Testing the PWM and Braking functions of the DRV8871 driver and 775 DC motor with an AS5600 sensor.
Curiosity is a strong driving force; especially, when there is a note on the datasheet regarding braking and PWM control. You can see the note …
Exporting Greyscale Image Data from an ESP32-CAM to Excel via Serial, while Displaying on a GC9A01 TFT Screen.
This is a post about how to export image data from an ESP32-CAM via serial, and how to them import it in to Microsoft Excel
Running Camera & Display on Core 0 of the ESP32-CAM
This uses the same setup as the original experiment which achieved 32FPS by splitting the duty across the two CPU cores. However, as this only …
PCB Manufacture with LASER diode
Currently, all of the electronics in my projects are made using copper strip board (vero board). This is great for through-hole components, and larger SMD …
Rendering 3D Graphics Using an Arduino Nano.
This started as the result of misreading the title of a Reddit post by u/Trotztd and lead to rendering 3D graphics on an Arduino. The …
Using SMD Resistors on Vero/Strip Board
When prototyping, my preferred protoboard is Verobaord/Stripboard as it has handy 2mm wide copper busses set at a 2.54mm (0.1inch) pitch. As a result, there …
Printing TPU Filament with a Stock* Ender 3 & Bowden Tube
Sometimes the best way to learn a new thing is to use it in a new project. This little project was a short and successful …
More Microwave Madness
Work begets work. For example; if you send an email, you'll likely get a reply which needs actioning. Or, if you finish your work early …
New Addition: Photon Mono SE
After much deliberating, I've taken the plunge and invested in an SLA resin printer. Sourced a second-hand Anycubic Photon Mono SE printer, complete with the …
Three More Side Quests
Instead of concentrating on the proper projects, I've devoted my time to literature, recycling and wood working as detailed below. Taking procrastination to a new …
Side Quest: 2 Player Space Shooter Game
Apparently I get distracted easily. This was another project that reached 85% and then sat idle for several months. Here is a write up documenting …
