Home Made Servo Tester

 

Mikael Pedersen is one clever guy. He's built a very impressive home made servo tester with many cool features. From his site:

• 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.
• 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 for future expansion.
  

Mikael has complete hardware plans and the software needed to build your own tester freely available. If you're a servo geek and handy with a soldering iron, check it out!
