Looking at what will work for a KAP community project the simplicity of Simon Harbord’s rubber band powered AutoKAP rig looks appealing:
This thing is going to need testing and, because I expect it to be flown from a relatively small kite ( I have 1.6, 1.5 and 1.3m rokkakus lined up for testing) I’m holding off cutting tin until I have assembled all the parts but I have questions about it that are hard to find answers for:
How long will it run?
How big a rubber band?
How heavy will it be?
What sort of interval should I set the intervalometer for?
Can I get a class of children to assemble it with out a rubber band pinging war breaking out?
Why is ‘Silly Putty’ now only available as expensive ‘Science Putty’ and what does this tell us about the nature of science today?
Will the tilt gear be too difficult to make?
Will a fixed tilt design be a better bet?
What will the image cover be like with a constant shift in pan and tlit?
Only one way to find out: build it and see!
