I love LED chasers. A bunch of LEDs neatly turning on and off on a precise timing – lights running one way, then the other way… It’s relaxing, soothing, and hypnotic. There are so many LED chaser/scanner/sequencer circuits out there, some are made with discreet transistors, some based on logic ICs, and more and more …
Introduction In our final project, we used CMOS camera to identify interval binary 0 and 1 sequence represented by black and white bars. Then, we used WIFI module to transmit the sequence to personal computer and displayed it on a web page. In our projects, we chose OV7670 CMOS camera and ESP8266 WIFI module for …
Introduction The goal of this final project was to create a lidar 3d imaging system while on a limited budget. This is a system which takes many distance readings while pointing at many different angles. These distance readings are then converted into cartesian points and then plotted onto a graph. By plotting thousands of points, …

Since the internet remains quite vulnerable to security breaches, new measures have been taken to ensure that users are able to safely interact and navigate it in no time. Earlier last year, a new security model called the FIDO2 WebAuthn (Web Authentication) that helps to eliminate all forms of password theft and replay attacks was developed by the big …

Some time ago I sourced a number of very cheap SD card sockets from China for a hobby project I was working on. Sadly, when it came to PCB design, I couldn’t find the footprints for this particular socket anywhere – the part being a proprietary invention of the factory rather than a cheap knockoff …

Problem: with my previous work I can take a PCB x-ray at fairly high resolution (see bond wires like above) but the field of view is pretty small. The above x-ray doesn’t even cover an entire PDIP-40. How can I see the entire PCB?Linear stageLinear stages are great for this sort of project. As I’m …
