What did you build today (Pictures) ?

Today's progress on the new switch consists of finishing the basic 3D model of the wall switch plate and working on some of the programming.
For the wall plate design I do not have buttons as of yet, but the main part of the wall plate turned out good. I did the initial print in yellow because I am out of white at the moment. I am still trying to figure out the best way of printing it. In the video, you will see that the tabs are looking a bit rough. That is because I printed this one face down with supports for the tabs. If I decide to print them that way, it won't be bad because the tabs will be hidden under the wall plate cover. I will try printing them both ways to see which comes out better.
For the programming, I created a couple bitmap icons and did a sample of those icons animated on the screen. The animations toggle back and forth and each runs for about 10 seconds. One bitmap is a rain drop, and the other is a snow flake. The idea is to use these to display weather conditions. I will probably design some clouds and a sun as well and have 4 possible animated weather displays.

one step further...
ISP works, FTDI works, test code works, and looks like a genuine board :)
now comes the hard part :D@andrew
Where did you buy that green thing that sits on your work desk (it has some kind of ruler on it and squares). I don't know how it's called but I keep seeing it and I think I want one too. Thanks. -
@mtiutiu
here I use esd safe mate etc when I do electronics (maybe too much paranoid.. and I don't know if there are with ruler), but these green mates are nice for tinkering, sure.
if you google "cutting mate ruler" you'll find what you want -

@mtiutiu I got one of those blue silicon heat resistant mats with magnets so I can use the heat gun over it

Do you have a link for that? Sounds very useful, especially when soldering things that might get very hot (though maybe I won't need it as much after I get the PCB holder).

from my previous posts the PCB CNC milling came out as an interesting topic. maybe another method, working with photo resist PCBs and UV exposure, could be interesting for others. so, for those, who are interested in this, I just documented my solution (not the technique, but my tool) recently.

@neverdie they get on sale quite often on banggood but are also available on aliexpress: usually they are on 3 sizes and the biggest has some slots with a lid and others with magnets; there are also some small slots with numbers to keep track of the screws you are disassembling and a ruler at the bottom

@sincze I should have known. All you had to say was memory and it would have made sense, or should I say sincze. LOL. With needing to hold states of 900 LEDs, I am going to guess that they are WS2812 LED strips.

Reverse-engineering a bluetooth battery monitor from Conrad.The battery monitor has an Android and iOS app that displays voltage, but I wanted to read the data from an ESP32 (lower right corner of the pic).
This hack is probably worth a thread on its own, will add that later.

Maybe a bit off-topic, but I use octoprint as server for my 3d printer, and use Domoticz as homeautomation server. I want to know when 3D print is done, so I created a node-red flow that connects this via MQTT, so domotics shows print progress...

@bjacobse I literally just started using octoprint about a week ago. I am curious how you get the progress data into node-red to send over MQTT?

@dbemowsk
hi did you check the link I supplied? I rather discuss the topic in domoticz forum, as it could benefit other Domoticz/octoprint userrs
https://www.domoticz.com/forum/viewtopic.php?f=21&t=14021&p=162935#p162935
but I have installed on the octoprint the mqtt plugin, as my domoticz is also running both mosquitto and node-red, I specify the ip adress for domoticz in setup the broker in octoprint plugin mqtt,
