Hello,
ik would like to build somthing like this:
http://users.pandora.be/Ivevanlee/helpme/Untitled-1.html
many off-the-shelf stuff works only straight and I would like to build a
cheap version myself. If there is a good off-the-shelf product I would very
much like to know about it!
Controlling a stepper trough a computer is no problem and I have programming
experience.
Just absolutely no engineering experience :) Can anyone point me in the
right direction or answer questions like:
- is connecting a stepper the right way to go?
- what kind of wheels should I mount on the stepper?
- what kind of rails should I use?
- are any of these components easy to find?
any information you could give me would be welcome!
many thanks,
Ive

--Well I'd start simple and go with model railroad stuff, then scale
up from there. What sort of load were you expecting to apply; i.e. how much
torque will you need to hold position/change position?

that's a good idea. It should support about 1 kilograms (2.2 pounds), or a
little more. However... the weight extends to the middle of the arc (not
completely).
ok, some pointed me to this:

that's what i'm looking for... it's just really expensive... not sure if I
could build that myself :)

Please log in for more thread options This is too vague. Tell us, clearly, what you're doing.
If you only have a load of 1 kg, consider curtain track,
used for draw drapes. There are motors for such things.
Here's a useful system.

Hi Ive,
I missed the beginning of this discussion, and it's overkill, but would the
mechanism of
an automatic garage door opener do? Could be cheap, especially a used one...
