Motor controlled jalousie

prusaprinters

Set of 3d printed parts for the remote motor control of the standard manual jalousie.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, to stay on place). The mechanism does not face almost any forces and there for it is not necessary to hard fix it on the frame, it would work even without the glue.Print instructionsIdeal to print with PETG, layer height 0.2mm or 0.15mm. The gear wheel beter with 0.1mm.Supports usually not necessary except for the motor cover maybe.Electronics consists of (costs roughly 7$):NodeMCU v1.0 ESP8266 ESP-12E wifi modulestepper motor 28BYJ-48 with ULN2003 driverlimit switchunipolar transistor MOSFET N-channel (to power on the motor only when needed)capacitor 33uF2x 10k Ohm resistor1x 220 Ohm resistorset of pins, wires, connectors, home made PCBRecommended power supply: 9V 1AIf 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. With some modification could be also implemented to Home Assistant, that is my work to be done, but not priority.https://www.thingiverse.com/thing:4647890Works now for almost 3 years without an issue.Note: The stepper motor is small and not so powerful, for large windows it might have issues to move all slats fully up.
