Using Op-Amps Part 2: Voltage Follower

Jesse Allison continues his primer on using op-amps for conditioning your sensor data. This article focuses on the voltage follower - a simple but very useful design for working with sensors.

Tomas Henriques' Meta-EWI Project

Tomas Henriques has created a beautiful extended version of the EWI using a Teabox and Electrotap sensors. Some pictures of his customized controller and information about the project are presented.

Using Op-Amps Part 1: Scaling Sensor Voltages

Jesse Allison provides a primer on using op-amps for conditioning your sensor data. These techniques are essential for scaling voltages into the optimum range for conversion into a digital system. The info provided here applies not only to those building their own sensors, but also to those wanting to improve the range of pre-built sensors offered by many companies.
