Update ()
It's been a little while since the last update but I've been quietly working on things behind the scenes. I've been working on a data logger using environmental sensors, an ESP32 and a SD card. This hardware and software for which has been developed. I then came to writing the accompanying article and was quickly reminded that my self built.....
It's been a long haul but getting there. An update ()
The story...As a lot of you may know I've been inactive for a while and then back in around early February the website went dark too. These two events were totally un-related but it must have seemed like I'd abandoned everything. I hadn't but with just being a one man show and having a job and real life I was.....
Quickie: Working with IR (Infra Red) Temperature Sensors - easier than you think! ()
IR sensors for temperature detection are extremely easy to set up and use with our microcontrollers, only 4 wires needed and two of them of for power! If you're a video kind of person then here's the accompanying video, otherwise read on below for more textual instructions!

BASICS: Finger Print Sensor on Arduino - with Lego safe! ()
Video is below, click to view... In this episode I look at a particular type of fingerprint sensor, the JM-101. It goes through how to store fingerprints on the device, how to clear them and how to check for a stored print. Spoiler alert: I'm not too happy with this particular sensor, with that said here are some affiliate.....

Using multiple ili9341 screens with tft_espi library ()
Ever wanted to run more than one screen independently? Are you using the excellent tft_espi library? Well this guide will walk you through the small bit of work you need to do to achieve this, in particular with an ESP32 but the principles can be applied to any MCU of your choice. Now, disclaimer. This library was not conceived to.....
I2S Audio Library (I2SAudio) Source Code Released ()
OK, so sorry for such a long wait but at the time I started this project I envisaged working on the I2SAudio library (and other projects) far more than I did over the last year. As it happens circumstances have dictated a much lower release schedule for videos and articles and so I've decided to release the Alpha Source code.....
Building a 6502 Computer: The System Clock ()
Intro In the last article we learnt all about the various pins of the 6502, today weâre going to look at the various ways of supplying a system clock, power up and see perhaps things you were not expecting. The you tube video is below and the main article follows. Parts list/affiliate and none affiliate links Affiliate linksUSBreadboards :.....
Building a 6502 computer: Episode 2, the pins of the 6502 and connecting for a basic system. ()
IntroHere is the venerable 6502 processor, in this series of articles we are going to build a full computer system based around this 8 bit brain. Today we are going to look at the various pins and how we need to connect them to create a basic system. A supporting video is available. Affiliate and other links for parts.....
