Digital Tachometer Questions |
|
|
I am preparing to do a review of various arcade trackballs and had the
idea of using a digital tachometer to measure how fast the trackball
would spin.
The idea is I can take a power source, like an r/c car's wheel and
bring the trackball up to a known speed. Then I would take away the
power source and measure how fast the trackball continued to spin and
for how long.
I have a few questions if anyone has used these before.
1. With a laser and or infared tach, will I need a "dot" or mark on the
trackball to get a reading?
2. Does anyone know of a tach that has a PC interface that would allow
me to create a chart of the speed to time distribution?
3. Lastly, I also need something to assist in measuring the tracking
performance of the trackballs. Do they lose accuracy while moving
faster? DO they skip? etc. I have seen little mouse type
applications that do similar things but nothing that records results.
If anyone knows of something like this please let me know.
