Neodymium Magnet

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. Due to different manufacturing processes, they are also divided into two subcategories, namely sintered NdFeB magnets and bonded NdFeB magnets. They have replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.

The “CO2” Project

“Environmental sensing and air quality have always been fascinating to study. I’ve tested various sensors over the years that, until recently, cost next to nothing. The COVID pandemic increased my curiosity (and concern) about indoor air quality, CO2 levels …

The Gauss Speedway

“Here’s a fun toy project I finally finished this month (Nov ‘22). It’s a racetrack built with a printed circuit board, and small 3D printed magnetic cars. They just drive around the circuit when you apply (the right …

A precise linear magnetic position sensor using LInterp

“Virtualise a non-linear sensor into a single linear function using the LInterp PROGMEM array generator This tutorial shows you how to “Virtualise” a non-linear magnetic position sensor to produce an accurate linear position measurement from a single function call. It …

Tim’s Electronic Pantograph

“This is part two of my Hall-Effect Sensor Trilogy. It is best to read the first part if you haven’t first: Tim’s Electronic Dividers [1D] : 13 Steps (with Pictures) - Instructables In this instructable I will be using two …

Mini Filament Counter for 3d Printer

“A couple of months ago I got a new roll of pla, I was printing things for a few days without any worries. Last week I went to print a large piece, 200 meters of filament according to Cura… I …

Tim’s Electronic Dividers - 1D

“I thought I would do a small tool. A Pair of Electronic Dividers, to show the basic principles of a Hall-Effect Sensor. I did a little video just to show there use, while I was making the video I thought …

ESP-32 Based BLE Mouse With Magnetic Mouse Pad

“This instructable is about building an esp32 based BLE mouse, unlike using the traditional method to build a mouse using optical sensors, this mouse works based on magnets embedded in a custom 3d printed mouse pad. Make sure to read …

DIY 3D Printed IoT Weather Station Using an ESP32

“Today we’re going to be building a wireless outdoor weather station that takes temperature, humidity, barometric pressure, light and wind speed readings. The data is then posted to the cloud and can be accessed through a Thingspeak dashboard on …

Floating Hexagon - Magnetic Tensegrity - 3D Printed

“… another contribution to the topic “Tensegrity”. The main difference to the other models is that the tension in the middle is not created by a thread but by the attracting force of two magnets. Therefore the top is of course …

Building DIY Split-Flap Displays

“It’s incredible how far display technology has come. Nowadays LED walls are found at every major concert venue, flat panel televisions are ubiquitous, and everyone has a high resolution, full color LCD display in their pocket. It’s difficult …
