Simple Linear Actuator

prusaprinters

<p>This is a simple linear actuator that can be used in all sorts of halloween or other holiday displays. I used a cheap yardstick for the rod with a GT2 pulley and belt system connected to a NEMA 17 stepper motor.</p> <p>I used this design to make a fun project for an Intel Edison Hackathon. The piranha plant movement was triggered by people sending tweets.</p> <p>Check out my blog to read about my other projects: <a href="http://matthewcmcmillan.blogspot.com/">http://matthewcmcmillan.blogspot.com/</a><br/> Follow me on Twitter: @matthewmcmillan<br/> Watch my 3D Printer make things: @MattsPrintrbot</p> <p>GT2 pulley and belt: http://www.amazon.com/gp/product/B00WW256TY<br/> Stepper Motor: <a href="https://www.adafruit.com/products/324">https://www.adafruit.com/products/324</a><br/> Stepper Motor Mount: <a href="https://www.adafruit.com/products/1297">https://www.adafruit.com/products/1297</a><br/> Stepper Driver: <a href="https://www.sparkfun.com/products/12779">https://www.sparkfun.com/products/12779</a><br/> Limit Switches: Any long arm microswitch should work.
