This project is a great marble machine made by David HASLE and is using a PICAXE microcontroller, a servo, batteries, and some wire. The wire structure is oscillating up and down and the marble travels all the way round. Check the video on the link below. [via]

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]

PID motor control with an Arduino from Josh Kopel on Vimeo.
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]
