Testing the movement of the lights on B9

Testing of the 7 fingerlights and the crown movement on my scratch-built B9 robot. The bulbs need to be fitted in the ends of the fingers, but this is just to test the movements.

The motor is also a little fast in this test as the speed controller hasn't arrived yet, the speed should be just 7rpm.

The motor seems a bit fast to me. I've also notice that all readily-available cams just alternate the finger lights. I saved some clips from early episodes that show the movement, and it is much more "wiggly" and randomn. I'll be making my own cam shortly - just cut my bubble lift cam today.

@MisterEnd1 yes the motor was too fast but thats been taken care of now with a small speed controller wired up to the torso knob, which means that I can slow it right down to barely moving if I wish. Also I've found that slowing it down makes it quieter too.

As for the cam, well I made my own and this was the first attempt. the profile has been altered a few times to get a smoother action but there is some variation in the 'regularness' of the lifts as it was all done by hand files anyway.

It occured to me today that it would be possible to make a 2 or 3 track cam so that adjacent light rods moved completely differently. From what I remember of the video clips I had, the original might have been that way. I was curious whether you are on the builder club site. I was a member for a while but now just a squatter.
