The Spice of Pi - Blog Doug 8

I have finally assembled the complete mechanical system. Both the carousel rotation mechanism and the jar lifter mechanism have been mounted on the bamboo base plate. The video below shows the first operation of the complete mechanism.

Hopefully the PCB I designed at the beginning of the project will arrive soon so I can get the electronics build completed.

And then it is on to the software....

    Doug, Great job! I don't know if I am having a slow internet day, or if there is a problem with your video, but I could not get past the 10 sec mark of your video. I will try again later. Gene

    Nice video showing the operation. I also had a problem viewing in within the blog, I got to 15 seconds and it then stopped, but it played fine when viewed directly on Youtube. Kind regards

    If problems persist, I will reload the video.

    Good starting point.

     

    You might get some issues with fuller jars due to the change in momentum with the extra mass.

    You might also need some additional gearing to get the torque levels more consistent for a smoother rotation.

    I'm not sure what the issue is. The first time I viewed the blog, the audio got out of sync when the rotating segment started, but I restarted the video and it seems to work fine now on both IE and Chrome.

    Doug,

     

    Great job!  I don't know if I am having a slow internet day, or if there is a problem with your video, but I could not get past the 10 sec mark of your video.  I will try again later.
