How to Use a DC Motor as a Servo with PID Control

Printer machine is one of the essential gadgets, in either home or office. However, have you ever opened up any printer before and maybe do some modification on it? Well, if you never try it before, today’s the perfect time to perform the task, as you’re learning on how to use a DC motor as a servo with PID control! Did you know that the newer ink jet printers are mostly use a combination of a DC motor and an optical encoder? The main purpose of using the two components is to take the place of stepper motors for print head positioning and paper feed. PID motor control with an Arduino from Josh Kopel on Vimeo. Normally, the motors themselves are a very good option, if you want to make… Continue reading

The Astounding Nickel-O-Matic Robot!

Robotic is always a very fascinating stuffs, as it can be used to perform different kind of tasks after you’ve well-programmed it. If you’re one of the loyal fans of robotic, then you must check this Nickel-O-Matic robot. The main goal of this Nickel-O-Matic robot is to print a cool message on a wooden token. It’s as easy as ABC to develop this Nickel-O-Matic robot. It uses inkjet technology to print a custom message on both sides of 1-1/2″ diameter blank wooden nickels. A BASIC Stamp 2 is being used to control the mechanical movement while a Propeller Chip is for controlling the inkjet system. Both of the controllers run a total of four hobby servos, three stepper motors, one DC motor, one DC vacuum pump, one inkjet head and… Continue reading
