Arduino Powered Micro Quadruped

“From the previous projects on this page, you can probably see that I have a deep interest in robotic projects. In one of my previous Instructables, I built a quadruped robot using large heavy-duty servo motors, and this time I …

Audio Spectrum Visualiser with Colour Selection

“Choose the colours of the LED strip using Hue/Saturation/Value parameters, flick the switch and watch your music come to life through FFT. I was intrigued by the possibilities of addressable “Neopixel” RGB LEDs. I wanted to learn how …

Automatic Arduino Powered Camera Slider With Pan and Tilt

“Are you fed up of shaky footage that ruins your video? In this Instructable I attempt to address this issue by building my own automated camera slider. I used the power of CAD and digital fabrication to create a robust …

Build Your Own DIY 3D-Printed Soldering Fume Extractor

“If you are an electronics hobbyist, soldering is essential in almost all of your project, but the smoke/fumes from burnt solder and flux isnt something you want to breathe. It smells bad and can be very dangerous to your …

Clock Multiplier – Crystal Frequency Generator using PT7C4511

“This is an easy-to-build project and it is the most cost-effective and high-performance frequency multiplier, which instigates analog phase lock loop techniques. The circuit provides high-quality, high-frequency output from lower frequency crystal or clock input. The project can be used …

DIY Arduino Musical Instrument-Theremin with 4 Sound Modes

“This instrument produces tones or sounds based on the light that falls on the surface of the photoresistor. The Theremin is an electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after its inventor, Leon …
