Modify Servo Motor for Continuous Movement - Servo motors are widely used in precise control applications, but most of them can rotate up to 180 degrees only. Presented here is a process for modifying servo motors so that...__ Electronics Projects for You Modifying a Servo - i was in need to modify four expensive JR-DS8231 Ultra Digital servos to rotate 360° instead of the standard 130° or something. The mods were required so they could be used with a tethered blimp. The infra-red and night vision camera equipment is mounted underneath the blimp on a special frabicated aluminum cage and is radio controlled (Tony van Roon's R/C) __ Designed by Tony van Roon VA3AVR

PIC Micro Multiple Servo Motor Interface - Using a modified version of the last program, we can control as many servomotors as we have i/O lines on port B. in the next listing, we will control two servos in the same manner as we controlled a single servo in the previous program. The circuit is shown in figure 4 (below).

PIC MicroController Servo Motor Interface - in our first program , we will simply sweep the servomotor from CCW to CW and then sweep back. The program will be kept simple as to demonstrate the priniciples of controlling a servo with a the PIC Basic language. The schematic can be seen in figure 2 (below).

Pulse-Width Adjuster Reverses Servo Motor - 03/17/94 EDN Design Ideas: Typical remote-control systems and robotics applications use standard R/C servos, which often require a reversal of the direction of rotation. Since varying the input signal's pulse width between 1 and 2 msec controls the servo's output position, a circuit that adjusts the pulse width Design by Joe Utasi, Jomar Products Corp, Cincinnati, OH
RC Servo Tester with 555 IC - Servo refers to an error sensing feedback control which is used to correct the performance of a system. Servo motor is a DC motor equipped with a servo mechanism for precise control of angular position. Servo motors usually have a rotation limit from 90° to 180°. Servos are used for precision positioning in robotic __ Designed by T.K. Hareendran
Serial Servo Motor Controller - Several people contacted me about our other project for controlling hobby servo motors with the PC serial port. Servo Commander was designed after quite a few people asked for a version of the serial servo controller that would let the user select a different serial port on the PC, and had the ability to control 8 servos.

Servo Controller - This circuit can be used to manually turn a servo clockwise and anti-clockwise. By pushing the forward or reverse button for a short period of time you can control the rotation of the servo. __ 555-Timer
Servo loop improves linear-regulator efficiency - 8-Jul-04 EDN Design Ideas: Linear regulators are easy to implement and have better noise and drift characteristics than switching approaches. Their largest disadvantage is inefficiency excess energy dissipated as heat. Several well-known techniques are available to minimize the input-to-output voltage across a linear regulator Design by Aurel Gontean, Technical University, Timisoara, Romania
Servo Motor Controller - This is the simple basic design of servo motor controller with pulse generator. it uses the CMOS
IC 7555 in the Astable mode to generate pulses to drive the servo motor. The circuit can be suitably modified to get pulses of sufficient length. A Servo is a small device that has an output shaft. This shaft can be positioned to __ Designed by D Mohankumar

Servo Pulse to Voltage Converter - A while back a Discover Circuits visitor needed a way to convert servo pulses from a radio controlled device into a voltage. The drawing below, illustrates the pulse train of the received signal. The time between pulses is a fixed 20ms while the pulse widths vary from a low of 1ms to a high of 2ms . . .

Servo Signal Trigger - The main inspiration for setting up this site, this little creation allows you to effectively add functions to your existing R/C set-up for models, robots, model robots, etc. i'm selling kits on Tindie along with a few assembled ones and some bare PCBs. You can also Email me directly (see about page for contact details) and i'll sell you one for 5% less (ie. without Tindie's charge) , but this way I can only guarantee stock when I confirm your order. __ Designed by Kevin Koster
Servo Tester - This circuit can be used to manually turn a servo clockwise and anti-clockwise. By pushing the forward or reverse button for a short period of time you can control the rotation of the servo. it will also test a servo. __ 555-Timer
Servo Wiring Chart - After 1991 or so (i can't remember) , most of the major brands of servos became compatible with each other. You can use any of these brands of servos with any brand of receiver. Some brands of servos are really great for a particular use in a particular plane, and there are other companies that sell their servos with each different __

Simple Circuit Servo Controller using 555 Timer - Servo motors have many uses in everything from robotics to puppetry to photography and beyond. These little motors can position their output shaft to any position on command hold that position. Most servos have a range of motion to about 210 degrees and thankfully are very easy to control with a simple circuit such as the one presented here. Using just a 555 timer and a few support components this circuit can control a servo through it's full rotation based on the position of a pot. This circuit was originally published in the Think Tank column of the October 1995 issue of Popular Electronics. __ Designed by Aaron Cake
