Working with graphics on microcontrollers has always meant focusing on making the most of limited resources. Particularly in the 8-bit era, all manner of tricks were used to get low-performance chips to achieve feats beyond their lowly station. However, these days, we’re blessed with 32-bit workhorses with clock speeds in the tens, or even hundreds, […]

This is an Instructables on how I Remixed my old CNC Laser engraver and made a Stable version of an Arduino based Laser CNC engraver and thin paper cutter using old DVD drives and using 250mW laser. Old Version of My CNC :https://www.instructables.com/id/Mini-CNC-Laser-Wood-Engraver-and-Paper-Cutter/ Old version was not much stable and had some wobble due to […]

Ever tried to get out of bed quietly at night only to trip over something and wake up the whole house? Motion sensing night lights installed discreetly under your bed provide low-level light bright enough to guide you around those stray LEGO bricks but dim enough so you’re not woken up fully. As well as […]

After being accidentally locked out of my house on more than one occasion, I decided that there had to be better way to entering my home that did not involve breaking and entering (and without hiding a key outside somewhere). On taking a look at my garage door set-up I noticed that the motor to […]

While most analog televisions come with composite video inputs on a yellow RCA jack, the feature is not universal. This problem was even more prevalent in the 1980s, and most home consoles got around the problem by instead feeding video to the television’s tuner with an RF modulator. [Manzel Seet] had just such a television […]

Hello! My name is David, I am a 14-year-old boy living in Spain and this is my first Instructable. I have been building robots and fixing old computers for some time now and my robotics teacher told me that it was good time to start sharing with other people what I have learnt. So here […]

All the versions of ultrasonic radars I have found for arduino devices (Arduino – Radar/Ultrasonic Detector, Arduino Ultrasonic Radar Project) are very nice radars but all of them are “blind”. I mean, the radar detects something but what is it detecting? So I propose myself to develope a system able to detects objets and identyfy them. […]

A pyranometer measures the sun’s irradiance (power/area, basically “brightness”) on a surface. Despite the similar names, it is completely different from a pyrometer, so stop right here if that is what you are looking for. This Instructable describes how to build and test a modified version of the pyranometer kit offered by Dr. David Brooks of the […]

Feature creep is typically something to be avoided, since watching a relatively simple project balloon into a rat’s nest of complexity often leads to ineffective, or even abandoned, projects. On the other hand, if you can maintain a tight focus, it’s not always a bad thing. [cbm80Amiga] shows us how to drill down and add […]

Microwaves used to be simple to use. Set the dial for the desired time, and hit start. Then, everything went digital and the average microwave now takes between four and six button presses in precise order just to start heating. Music players have gone down a similar path, and those that grew up in the […]
