Alex the Giant Introduction
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 circuit. Finally, we'll go a bit further and build a wireless power floating light.
Required Materials
To follow along with the examples in this tutorial you will need the following materials:
Heads up! The LM358 is scheduled for EOL. We recommend the AS358 as a drop in replacement as the general purpose op-amp. The part is compatible with the 358.
The other parts used that we don't carry are:
- Analog Hall Effect Sensor
- 1N5401 Diode
- 1mH Inductor
Required tools
The tools needed for this project is a multimeter and soldering iron, but having access to an oscilloscope will help with testing as well.

Introduction to Operational Amplifiers with LTSpice
Picking up where we left off in "Getting Started with LTSpice," we delve a little deeper into LTSpice through an introduction of Operational Amplifiers (OpAmps).
