I think this has uploaded ok.
I could save myself a lot of time by making simpler prototypes but my thought process needs me to work at having something near to the finished article to start with.
Also this approach allows me time to think about the mechanics that will make it work.
However , totally different ball game here!!
Really have to work out the programming for the "works" first.
At the moment I can make the mermaid swim with the 360 servo but the 90 servo for the sharks jaw?....zero.
I can make it all work from the 360 servo but that would mean introducing a belt drive plus a few cogs, not quite what its all about.
Nevertheless, been a very interesting 6 weeks. Coming away from this with what I've learnt is that I need to learn a lot more!
All the very best to you all and your Computational Contraptions!

An idea: using the positional servo motor to control the exact position that you want your cranky contraption to be set at -Celeste

The code says, "on button A press, set the positional servo motor to 180 degrees. On button B press, set the positional servo motor to 0 degrees."

The above make code worked brilliantly and ran my automaton.  However since I have run the LED programmes and re-installed the servo programme, only one servo works.  Any help will be hugely appreciated!  The visual runs perfectly.

Very many thanks Ryan for all your help.

Sorry about the angle. Just got the basis for my bowing performer working. Arms etc to come.

not quiet work at the moment -Cindy

the A button makes the scroll run, the B button "rewinds" the scroll, pressing A and B together stops the motor.

Here's how it works. I think it would work a little better with two continuous motors so that you can automate the rewinding that you see me doing by hand.

I was inspired by platformer games like super mario and "crankies" http://www.thecrankiefactory.com/348971240 . I wanted to make something that needed a motor to make it more fun or interesting. I'm using pieces of the cardboard automata kit here, but made a few tweaks:

I cut my own cams make the character "jump" higher

I cut down the chopstick that the character is attached to

I added some sticky tack to hold my cam in place

I added a couple clothespins to constrain the movement of the character and to keep from spinning around in a circle

I also used one of the boxes that our electronic parts came in to make the cam and the upper portion of this piece (those boxes are too good not to use!)

Riffing on the cranky contraptions. Straightened the crank and poked it into the servo horn. It took a bit of fine tuning to get it to not want to tear itself apart. Continous servo running at 50%. Simple A press on. B press off.

I can make the spaghetti go round but it doesn't stop. I want the plate to rotate left and right in short movements as the spaghetti goes round. At the moment the plate crashes with the spaghetti.

I have successfully programmed the 360 servo to come on when the microbit is tilted to the left, it stops when it is upright.

My challenge now is to construct the dragonfly automata so that the microbit and servo is integral in the machine. I'll probably start with a box.

I used some pieces of conductive tape to attach a switch I made out of cardboard to the micro:Bit logo so that when as long as I am pressing and holding the switch, the motor runs.

I got the continuous servo showing the monster orbiting the sun. Had to troubleshoot the angles and now want to make the moon wobble due to the disturbed gravitational forces. ;)
