Everything from go karts to electronics and Arduino.... At age 14 possibly the youngst person to make a prusa mendel? Intro: Jury Rigging A Servo To Drive A Low Voltage Motor (DIY ESC) Every good maker has used a servo at sometime or another. Whether it was for a RC car or an Arduino powered robot arm. I was working on building an Arduinopowered tank. I tried using continuous rotation servos as the drive motors, but it was much too slow. I knew how to interface a servo with an Arduino, so I really wanted tostick with this and didn't want to pay the money for a motor shield. Then I got creative....I designed this device to allow me to control a motor with an RC receiver/transmitter setup, but the same system can be used with an Arduino! It has full motion control,going both forward and backward, and speed can be controlled. For the RC minded, this is just a cheap, DIY Electronic Speed Controller, much like those in Rc airplanesand Helis! NOTE: When using with Arduino:Program this with the servo library as you would program a continuous rotation servo.This can be used with Arduino as long as a seperate battery is wired, it may draw too much power from the Arduino if ran directly off the Arduino's 5 volt pin!Image Notes 1. The Final Product2. Tamiya Gearbox with Motor Step 1: Parts And Tools For this project you will need:Materials:Servo (I used a Parallax servo avaliable from Radio ShackDc motor (mine is in a gearbox)Hookup wireTools:Soldering iron and solderDesoldering pump or braidNeedle nose pliersSmall screwdriver  http://www.instructables.com/id/Jury-Rigging-A-Servo-To-Drive-A-Low-Voltage-Motor/   http://www.instructables.com/id/Jury-Rigging-A-Servo-To-Drive-A-Low-Voltage-Motor/  Step 2: Open The Servo Use the screwdriver to remove the 4 long screws on the back of the casing.Remove the top with the servo arms. Then, take the gears and fittings out. Next, unscrew the servo arms so you are left with the top part of the casing that has a hole in itwhere the servo axle came out. When the screws came out, the bottom of the casing should have fallen off along with it. If not, just pop it off. You should be able to seethe pcb that controls the motor. Use the small screwdriver to unscrew the motor from the top of the servo there should be two small screws. Then use the screwdriver topry out the pcb and the motor, which is directly mounted to it. BE EXTREMELY CAREFUL NOT TO SNAP THE CIRCUIT BOARD! I did, then tried to solder it back. Imade magic blue smoke! :(
