Servo Tester 2 overview

Please use the links at the top of the page to get to the various sections.
These pages (and the software) are still being written, so please check back later for the newest updates.

The Servo Tester 2 is hardware and software that, basically, makes a pulse width signal between 1 and 2 ms. This is the signal used to control common R/C servos. There are numerous servo tester construction articles on the Internet. This one has some advanced features, not usually found on servo testers.

Feature list:

• Generates two separate signals for driving two servos.

• Sweep mode for stress testing servos.

• Input for reading a servo signal (from a receiver).

• Receiver signal quality analysis.

• Very high resolution at both input and outputs. 0.1µs (which equals 10,000 steps between 1 and 2 ms).

• Voltage and current readout. How much current does your servos actually consume? How much does your receiver pack drop under load?

• Simple user control. Access all features with just a single rotary knob with integrated push button.

• 2 x 16 character LCD.

• Optical tachometer.

• RS-232 connection. Write your own program (PC or whatever), that can control every feature of the tester. Future enhancement. RS-232 firmware not written yet.

License

The Servo Tester 2 hardware and software is free for non-profit use only. You may copy, build and use it as much as you like, as long as you don't make any money out of it. You are allowed to build some for your friends, as long as you only charge them for the parts used, not the time spent to build it.
But please bear in mind that I've spent a great many hours making this servo tester. I am curious by nature, and would very much like to hear how and where my creation is being used. So if you build one, please send me a mail with a few words, perhaps with a picture of it. Contact me here.
I may make a small gallery of various peoples testers, with name and a picture of the tester. But I won't include your email address unless you specifically allow me to do so. Please note in the mail whether you would like to be included in the gallery or not.
