This project is an analog PWM servo control. It details the design of an op-amp based, analog oscillator that can produce hobby servo control signals based on any analog input (be it a potentiometer, DAQ card, or something else). Check details on the link below.

CHEX is a perfect device for testing CCPM servo setup. This device allows you to connect 1-3 servos simultaneously. It can be used as a servo signal generator for testing electronic speed controller (ESC) without using a transmitter and receiver. Also, this device can be used to check other RC devices as shown in the features below.

This project is a servo tester based on PIC16F690 and with code written in C. The timing loop is a crude one relying on a simple tight loop, so the pulses are not massively accurate.The board has four modes of operation, selected using TACT switches with the status indicated on LEDS built into the switches .

This is a camera switch that uses a servo to activate the shutter. This page include links to the complete circuit diagram, the .HEX file required to program the 12F675, and complete construction details. The switch consists of a PIC and a small number of standard components. The Servo Camera Switch connects inline between the receiver and the servo and manages the operation of the servo.

This project over oomlout.co.uk shows how to build a robot able to cut resistors… If you are in need to cut a lot of resistors this will be handy. It uses an Arduino, a stepper motor, two RC servos, two exacto blades and a bundle of laser sliced 3mm MDF. It is able to produce resistors strips of any length. [via]

This is a simple servo tester which will comprehensively test the capabilities of almost any modern servo. It has two pushbuttons, CENTRE and SWEEP and a potentiometer which works as follows:

This is a nice example of scavenging parts from an inkjet printer to make cool stuff. It uses an Arduino and a Motor Shield to control the DC motor. The web site has a lot more information and the source code to get you started. [via]

Servo motor is very useful in robotic. I used servo motors to create few robots in the past. But I never think of using servo motor as input device, and mahto did it. Making servo motor as input device, you can now record the position of the servo motor and play it back the sequence of actions afterward. [via]

This servo tester can control two servos independently. It can analyse the servo signal quality from your receiver. It measures voltage and current under servo load. It can be used as a tachometer, and with a later software upgrade it can also be remote controlled from a PC.It uses a rotary encoder for fast and intuitive navigation of the menus, which make it even more simple to use than the old 4-button tester.
