WE HAVE LIFTOFF!!!
Friday dougw gave me the assembled platter and some spice bottles to help work on the code and voice control aspect of the project. So I rushed home to de-solder my servos from my Voice board and attach some headers to attach the platter servos. It was then I remembered that I had lent my soldering iron to my brother (who lives about an hour away) to do some rework on his 'vintage' stereo amplifier collection. So this morning I made a trip to the electronics store to pick up a new iron and some solder.
After I had soldered on the headers I attached the servos and made them move, although not by voice command yet...
You will see that the outer ring bottles seem to lift higher than the inner ring. I am quite sure that the lift action is the same on both sides, so I think it is because the inner lifter is not as close to the center of the hole as the outer ring, as shown by the picture below:
I also spun the platter in a circle, and watched it go back and forth:
Now to find the right PWM values for the outer ring so I can stop the platter in the middle of the jar so the lifter has easy access to the jar with out hitting the edges accidentally.
