PIC16F877a is a low-power microcontroller device in the 16-pin family of PIC® microcontrollers. It features an enhanced instruction set, greater program space and data memory space than its predecessor, and on-chip peripherals to simplify system...
Many years ago when I was designing an infrared camera slave pointing system the cost of an infrared receiver IC (integrated circuit) was about $7. This IC was TTL (Transistor Transistor Logic) with three pins. Power, Output and Ground. Then the price...
Ever dreamt of your own single board computer? Well, Raspberry Pi makes it easier for you to build your own single board computer. The Raspberry Pi is a single board computer which plugs into monitor, TV or directly connect wireless with laptop...
Requirement low power : 3V3 or lower, not 5V powered at least 7 GPIOs, 9 preferred. We don't want to read the status of the switches with an ADC. as small as possible cheap easy to solder Availability : 2nd sourced PlatformIO / Arduino support...
Originally published in 2012, this marked the start of my electronics journey. This Christmas, I received a copy of Make: Electronics (First Edition) by Charles Platt, along with the accompanying Make: Electronics Components Pack 1a from Maker Shed....
The Sipeed Longan Nano development board by Seeed Studio is based on the Gigadevice GD32V which implements the RISC-V architecture. It has an impressive list of features, which you can read for yourself. Low power consumption is claimed as one, a third...
Well here's another year :) I've made this as a space to manage my thoughts on this Zx81. To be honest there's probably better examples out there as to the correct way to do this. I would direct you to these places first. But if you're interested...

I lost all the images here! Links and uploads! :( slowly rebuilding... Project Ideas... In order of most-recently-listed, first (read from the bottom-up):12-5-18: YES! 10-24-18: https://hackaday.com/2018/10/24/av-synth-is-psychedelic-analog-mayhem/...
Introduction Over the years since the inception of computers, many different software development strategies have been theorized and put into practice. Although many...
This project shows how to use the STONE display, STM32 microcontroller, ultrasonic sensors, and a servo. The purpose of the project is to be able to display the distance measured by ultrasound in real-time through the STONE display....
If you have ever tried to use a third party serial module to send info to an ardueno you may know that generic $1-4 adapters on eBay just don't wok, unless you press the reset button at the perfect time during upload. Or you have gotten this error below...
Briefly: 80-wire IDE cables are *great* for high-speed stuff... But the pinout is a bit more difficult than a straight-through 40-wire IDE cable, because the 80-wire cables have shielding (yay!) which is connected to specific pins designated as ground,...
