Using an ESP-32 board with an embedded E‑Paper display, I created a gadget that shows status information from my web server. E‑Paper, also known as E‑Ink, only needs power when being updated, and uses no power between updates. This means that the gadget can be powered for weeks from a rechargeable battery. The purpose of … Read More
Using my DJI Spark drone and taking around 40 photographs using its built-in camera, I was able to make a 3D reconstruction of where I live: Above House Model Simplified by jonny5alive on Sketchfab Direct link if you are unable to view it on this page.
Manual Traffic Surveys Many people in the UK may be familiar with seeing groups of people, or sometimes a parked vechicle, clearly displaying a sign saying ‘Traffic Survey.’ These people are employed to keep a tally of the number of vehicles using a road, and the types of vehicles. This information is important for planning … Read More
My Sony smartphone has an unusual TRRRS (Tip-Ring-Ring-Ring-Seal) connector, allowing it to use very reasonably priced noise cancelling headphones (Sony MDR-NC31EM) that have an extra microphone in each earphone. I found that the Sony app Sound Recorder allows selecting recording directly from these two microphones, and are great for binaural recording, and I gave it a … Read More
“A prototype 3D-printed robotic hand that can be made faster and more cheaply than current alternatives is this year’s UK winner of the James Dyson Award.” (BBC News link) This is a fantastic idea, which has so much value to people without limbs. Bionic prosthetics can cost up to £100,000, and £30,000 for a single hand. The 3D-printed … Read More
This project entitled “Large-Scale, Real-Time, Visual-Inertial Localization” is interesting, using Google’s experimental ‘Tango’ hardware to improve real-time tracking of location and position. The hardware is a tablet computer with a motion tracking camera, a 4 megapixel 2µp pixel camera, integrated depth sensing and a high-performance processor. This equipment aids in tasks like scanning rooms. A … Read More
Interesting work by a team led by Nottingham Trent University on making a mobile scanner that can detect early signs of potholes. It uses conventional cameras, 3D scanners and computer vision to detect ‘ravelling’. Moving this around at traffic speed mounted to a vehicle, and combining it with GPS and a suitable logging system, it … Read More
