Dot Clock Extended (Home Automation)
Description
Just a little remix of Qrome's great design "ESP8266 Wemos Clock". I wanted to use this as an allround home automation clock. So to the standard parts: 1 x Wemos D1 Mini 4 x MAX7219 dot matrix display (https://de.aliexpress.com/item/32668446642.html) I added: -5V Buzzer for Alarms (via n-channel mosfet) (https://de.aliexpress.com/item/1005003300497363.html) -2 * 5V vibration alarm motors (both via n-channel mosfet) (https://de.aliexpress.com/item/4000336211252.html) -Top Button with led -BMP280 Temperature and humidity sensor (https://de.aliexpress.com/item/32848964559.html) Things to come: one or two sensor "buttons" on the top or side (no holes necessary) one or several dimmable 1w power leds (beads) on the back, to make some ambient/night light and/or some visual alarm. Changes on the 3d Model: BASE: -Extended display space My MAX7139 dot displays from china seem to be a few millimeter wider, and would not fit the original :/ (Negative volume "Display-Dummy" in the Slicer file) -Top hole for LED Button (one i had laying around) To mount a top button with LED -two "holders" inside for vibraton alarm motors LID: -added cable outlet for the wemos tray -added holder and hole for 5V buzzer -added holder and hole for BMP280 Temperature and humidity sensor be aware: Beeper and vibration alarms need to be connected to the wemos via some small n-channel mosfets. OTHERWISE YOU WILL KILL YOUR IO PORT!!! ;) This all runs smoothly with home assistant and a relatively simple firmware made with esphome.io If you use the prusa slicer file, you can easily change sizes and locations of holes, the size of the display and much more. Pictures to come....
