December Servocity Giveaway

The part that attached the blue servos

The part that attached the blue servos

While cleaning out my garage, I realized I had a Sub-Micro Pan & Tilt assembly from Servocity.com that I hadn’t used.  As cool as it looks, I’m going to be very busy in the near future, so maybe some readers of JCoPro.net could use it.  So I’m giving one of these pan-tilt mounting packages away to someone that comments on this post.

Please note, this is only the mounting to attach everything, and doesn’t include the little servos themselves.  If you’re wondering why you would want one, check out the video after the “read more” link for a video of one in action.

So if you want a chance at receiving one, leave a comment below saying that you’d like to enter the contest and how you follow this blog.  Then, if you don’t already, follow on Twitter, Youtube, or via email by checking to receive blog updates when they come out (you’ll also need to verify when you get a confirmation email).

I’ll decide a winner out of people that have signed up by midnight on December 31st and let you know via the email you left on your comment. Read more »

Introducing The Cigar Box Creepster

Something you may have seen previewed on my Youtube page was this “automated cigar box” that I haven’t quite figured out a good name for.  Several interesting names, such as the “CopBox,” “RedVSBlue,” and “Red Chomper” have been suggested, but if you feel you have a better name, be sure to let me know in the comments.

Even though I say “red” and “blue” at first to cause it to open, what really drives this device Read more »

Simple ATtiny Servo Control

ATtiny-arduino-servo

ATtiny, arduino, and a micro servo

This method may not be pretty, but for crude servo control with the ATtiny chip, this method should work.  I programmed it using an Arduino Uno as shown here.

Hobby servos work by taking the length of time a pulse of electricity is sent to the “signal” input.  If it is 1.5 milliseconds (ms), it moves to the middle of it’s travel, 2 ms to the right, and 1 ms to the left.  This excellent paper illustrates this, as well as some standard connector colors, which have helped me with some of my projects.

For my “tiny useless machine,” I needed a way to control a servo using the ATtiny chip.  Accuracy didn’t have to be great, so what I did was used the delay command to make the pulse either 1 millisecond (delay 1) or 2 milliseconds (delay 2).  The code below will show what I mean, Read more »
