wood lathe digital readout

“I bought a wood lathe a few months ago and I thought it would be fun to make my own digital readout. A digital readout is simply an electronic display that shows you the spindle speed of a lathe. I …

0 to 5V output Analog Hall Sensor for Foot Controller

“This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet …

MesoTune - Magnetic MIDI Controller

“Are you a music composer, melodist, symphonist or a tunesmith who loves to create their own beats, but got bored with all those push button traditional MIDI Controllers. So, this hardware is for you, as in this instructable we switched …

“a clock which rewrites time again and again This project is a continuation of my quest to build a robotic clock which can write and rewrite the time continuously day in and day out and keep going doing it. My …

Portable Magnetometer

“A magnetometer, sometimes also called Gaussmeter, measures the strength of the magnetic field. It is an essential tool to test the strength of permanent magnets and electromagnets and to understand the field shape of nontrivial magnet configurations. If it is …

Make Your Own POV LED Globe

“In this project I will show you how I combined a couple steel pieces with an Arduino, an APA102 LED Strip and a Hall effect sensor in order to create a POV (persistence of vision) RGB LED Globe. WIth it …

DIY Stepper Motor Clock with NXP LPC845-BRK

“This project is about building a stepper motor clock around the NXP LPC845-BRK board. The design is using a combination of 3D printed and laser cut parts and costs below $15. The GitHub repository (see links at the end …

Open Source Powered Prosthetic Leg

“With an ever-increasing availability of new technologies, we created an affordable bionic leg that is accessible to everyone. An accessible powered prosthetic — open-source and affordable. Simple, effective, assistive tech developed to accommodate continuous development. Brought to you by a bunch …

Project  Tachometer

Tachometer

“Hello everyone. This time I will share my way of making a digital tachometer. It works great and can easily compete with a commercial version. On top of all, I wanted to avoid the complexity of adding a battery to …

Magnetic Levitation

“Let there be light! In this tutorial we’ll build a basic magnetic levitator. This guide will go over some of the theory, how to use a magnetic field sensor, and how to use one to build a basic levitation …
