Interesting servo control circuit

I have earlier written about 555 timer design contest. 555 Servo Controller was winner in several categories. It looked so simple and “have seen that eariler” type of circuit that I wondered why this was so winning circuit:


Finally after few days I got time to check out the Simple 555 timer based servo controllers page to see why this won. The circuit is simple, but the video showing the applications of it was pretty amazing. So I no longer wonder why this circuit got the prices. This 555 timer based analog robotics video is very interesting to look at if you are into robotics in any way.

    I’m curious to find out what blog system you have been utilizing? I’m having some small security issues with my latest website and I would like to find something more secure. Do you have any solutions?

      I am using WordPress blog system.
      Wordpress has lately had some security issues, so with it you have to be careful in what plugins to use and remember to keep the system enough up-to-date.

    Interestingly reading the OPs topic I believe it since it’s true so it’s good to see a web guy that’s telling it for all to review!

    Turn any DC Motor into a Servo Motor

    In this video we will learn how to turn any DC motor into a stand-alone servo motor with a lot of features. Unlike regular servos that have limited motion of 180 or 270 degrees, this one has unlimited range of 360 degrees and in addition to that we have the ability to adjust the range of the rotation to whatever value we need. We can also set a custom center point, we can adjust the responsiveness, it has continuous rotation mode and it can be controlled through an analog input, digital input from a RC receiver and using the serial monitor from our PC.
