Motor controlled jalousie

prusaprinters

<p>Set of 3d printed parts for the remote motor control of the standard manual jalousie.<br/> Printed parts are attached to the jalousie control bar without any impact to the original control mechanism or window frame (except for a bit of glue).</p> <h3>Print instructions</h3><p>Ideal to print with PETG, layer height 0.2mm or 0.15mm. The gear wheel beter with 0.1mm.<br/> Supports usually not necessary except for the motor cover maybe.</p> <p>Electronics consists of (costs roughly 7$):<br/> NodeMCU v1.0 ESP8266 ESP-12E wifi module<br/> stepper motor 28BYJ-48 with ULN2003 driver<br/> limit switch<br/> unipolar transistor MOSFET N-channel (to power on the motor only when needed)<br/> capacitor 33uF<br/> 2x 10k Ohm resistor<br/> 1x 220 Ohm resistor<br/> set of pins, wires, connectors, home made PCB</p> <p>Recommended power supply: 9V 1A</p> <p>If you are successful in building, on Thingiverse (can not post here) I have some source code for the ESP8266 controller (Arduino IDE). Controller acts as HTTP web server over wifi. I am controlling using my Android application, but can go also easily using web page.<br/> <a href="https://www.thingiverse.com/thing:4647890">https://www.thingiverse.com/thing:4647890</a></p> <p>Note: The stepper motor is small and not so powerful, for large windows it might have issues to move all slats fully up.</p>
