Simple Linear Actuator
thingiverse
This is a simple linear actuator that can be used in all sorts of halloween or other holiday displays. I built this using a cheap yardstick for the rod with a GT2 pulley and belt system connected to a NEMA 17 stepper motor. I designed this project for an Intel Edison Hackathon, where the piranha plant movement was triggered by people sending tweets. Check out my blog at http://matthewcmcmillan.blogspot.com/ to read about my other projects. Follow me on Twitter @matthewmcmillan or watch my 3D Printer make things @MattsPrintrbot. The GT2 pulley and belt can be purchased from http://www.amazon.com/gp/product/B00WW256TY, the stepper motor is available at https://www.adafruit.com/products/324, the stepper motor mount is located here: https://www.adafruit.com/products/1297, and the stepper driver can be found at https://www.sparkfun.com/products/12779. I used VT16031C2 long arm microswitches for the limit switches, and Flanged 11/16"OD, 1/4"ID McMaster-Carr 6384K342 bearings, which work well. I also used 1/4-20 1" long bolts to secure the bearings.
