car power antenna.
Hey guys and gals,
need some help here. I need to automate a (light weight) panel to move about 6" back and forth. I'm guessing my best choice would be to get a linear actuator, but at $100 it's kind of a steep investment. What other options do i have for reliable repeatable automations?
I was thinking lead screws but by the time i get everything i need it's going to be close to the linear actuator's cost but not be as sturdy.
then i thought about getting smooth gliding track and a motor/wheel assembly with electronic switches at the beginning and end of travel.
any ideas? thoughts? suggestions?
you know what, i suggest that to someone a while ago. not sure how to wire it up though. it's worth looking into. thanks.
how much room do you have to play with?
Gen 1: Pentium 3 1GHz - ATX - 2005
Gen 2: Pentium M 1.6GHz - ITX - 2006
Gen 3: Pentium M 2.0GHz - 5.25" SBC - 2007
Gen 4: (coming soon: Core2 Duo - 3.5" SBC - 2009)
...it never ends
mbuchman, that's what he meant by lead screws
Power antennas are easy. Power, Ground and switched power. Get some NICE roller-bearing drawer slides and mount the panel to that. Then have a power antenna or two push/pull it.
How fast do you need it to go? I have a friend that built a homemade CNC machine using plain old threaded rod for lead screws... as long as the panel is mounted on nice smooth rails/rods, even a crappy lead screw isn't that bad; mount it in a non-rigid manner so that the sloppier tolerances don't make it bind up (flexible coupling to the motor, etc). Just doesn't move very fast, because of the thread pitch.
But don't take it from me! here's a quote from a real, live newbie:
