I'd like to make the rack at least 8 inches. How do I modify the length THANKS

Hello Andrew, Can you share the stp file of this design?

[@andrewdonatelli6953]

There's a link in the description.

I want to motorize my shutters. I kicked around the idea of using a timing belt and pulleys on each louver. I think Rack and Pinion is the way to go though.

[@ahmedit599]

If i want the rack to move when it detects a certain thing and not to move when it detects another.What type of sensors can i use?

[@ninom4926]

Limit switch by vex

[@user-ir6ug6gk1f]

hey andrew,could you tell me the code for interfacing it with arduino

[@andrewdonatelli6953]

Sure, I will put it on GitHub and send you a link.

GitHub link to the code Added to the description.

where is the solidworks file sldprt. ?

[@qassem3051]

How much did it cost you to make it

[@andrewdonatelli6953]

Just the price of the servo and $2 in PLA.

[@vikashshankar2556]

what type of servo did u use(servo model )?

[@andrewdonatelli6953]

It's an old Airtronics 94102 that I modified for continuous rotation.

[@manojkumard6008]

what is the maximum pressure can be pushed

[@nakinnovations8800]

Very nice

[@BHARGAV_GAJJAR]

Unguided rack is very brave

[@andrewdonatelli6953]

I like to live dangerously. LOL It's only moving 12 g.

Hello, what type of motor& where did you get it

[@andrewdonatelli6953]

It's an Airtronics 94102 servo that I modified for continuous rotation. Any standard sized continuous rotation servo will work. This one, for example: hitecrcd.com/products/servos/robotic-servos/hsr1425/product

Where to buy that rack and pinion gearset?

[@andrewdonatelli6953]

I modelled them in Fusion 360 and 3D printed them. There's a link in the description.
