but using superglue can't be very durable.
and for providing entertaining story lines
I don't remember much of that. It was a major prime-time TV series with a budget of ~US$1000000 per episode.
Hi,I'm a newbie too and I've been thinking about your project. It sounds like one of those Mythbuster-type problems you see on the discovery channel, where they test McGyver episodes for realism etc...If I wanted to build a cheap thing that moves a lightweight rod I would use a setup like in this attachment, I've seen the Mythbuster guys do this. You would need to play with the spacing of the free rolling wheels and maybe support the rod more. You might need thin tyres on the wheels to provide friction. I used some simple code from this site to play around with a toy motor:http://ardx.org/CODE03. I'm not an expert but I think you can modify the code to have it gradually start up and gradually slow down. As someone said a stepper motor might be good but I don't know what to do with that. I also thought you could gear the motor so you can control things more easily or make the so called free-rolling wheels less free-rolling so they are semi-braked (technical term a bit like driving with the parking brake half on, when you take your foot of the accelerator and put the clutch in, you don't free-roll.Anyway that's all I can think of right now. Hope it helps.Good luck

I'm sorry if my posts have not lived up to the standard you set for posts here but I hope you see that I've tried to be constructive and I haven't intentionally aimed to anger you." "I'm puzzled by some of the irritation I have caused. I can't for certain reasons give all details on my project. That might be disappointing but that is how it is""I want a certain arduino controlled physical movement. I want a rod to move out linearly 30 cm and touch something."
