What did you build today (Pictures) ?
-
Today I soldered a tiny MYSX board to recycle my EasyPCBs in door sensors as compact as possible. I can also use the "vertical" CR2032 holders I had no use for and make some space in my drawers.
It can use a normal or a NO/NC reed switch (for SMD allergies :D ) or a SMD ultra low power hall sensor and it has a footprint for a reserve capacitor to support the CR2032.
I guess this board will be of interest for @sundberg84 ;)
PS: sorry for the ugly soldering, my old 936 clone soldering station is in "zombie" mode and it's all I have until the new soldering iron arrives.

Not related to MySensors but I also assembled a first version of a battery powered led light, it's small and cheap and I will assemble a bunch to put around my home when there are some power cuts in evening/night. I'm using 3020 leds and they emit a lot of light for their small size, even with low current so I expect to get around 2 hours of battery life with the cheap aliexpress 16340 batteries, and way more than needed with the 18650 cells salvaged from my old laptop battery.
My first board with a li-ion charger and it is working well, now I'm waiting for the battery protection ics (cheap DW01 from AliExpress) to arrive as my batteries are not protected.

@nca78 Which 3020's did you get?
Cheap ones from AliExpress, not disappointed especially for the low price. I'll see in the long run how they behave.

Some more testings on my Logger... I want it to work great before moving on so alot of testing is needed. Why not do it on node #1 (note the old rev om EasyPCB).

Completely unrelated but a impossible project for me it seems...
Im building a wifi "babywatch" in a USB stick.
It sends sounds to a app/software which is build to run in the background. This to be able to game or watch video with headphones and still know if you have a angry child.
So pretty much Mic -> Amp -> ADC -> Esp8266 -> Wifi -> Software/App.
This seems impossible to do with all the interference. Everything works now (Rev1) but im now on Rev 6+ or something and I cant get rid of the noice in the Audio.
Seperate power supply + ground for analog and digital side but It seems like the Esp8266 inserts to much noice.
Well, it was a great idea but hard to accomplish.

@sundberg84
I really like that case. Do you have a link where you purchased it? -

@sundberg84 analog and esp8266 also beat me. Tried to play some music from an ESP8266 but result was barely usable. I switched to dac+amp connected via i2s which works fine.
Maybe you could try with a digital i2s microphone...http://yveaux.blogspot.nl

@nagelc - I use this: https://www.mouser.se/productdetail/789-p3a-220805s but note, there are 4 different variants. WIth and without opening for USB connector and other stuff. I can send you the footprint for the PCB if you wants.Controller: Proxmox VM - Home Assistant

Someday I might get a project complete enough that I will want to put it in an enclosure : )

The nice thing about owning a 3D printer is that I don't have to buy enclosures any more. I just have to buy rolls of plastic. The sky is the limit when you have a 3D printer. I do like that enclosure though.

Can't agree more, made a quick box for the lights with "crystal" PLA. You need a lot of imagination to believe it's crystal, but it's nice for a light enclosure as it acts as diffuser.

Today I'm trying out Thingsboard, which sort of is a controller, but on steroids.
So far, it seems quite capable, but I have a lot of learning to do. My first step was to integrate it with Sigfox, which seems to work.

Hey @mfalkvidd were you able to get mysensors nodes to send data to thingsboard? If so, I'm interested to know how you did that. Wondering if thingsboard can be configured as a controller for mysensors. Thanks!

@mfalkvidd no problem, thanks

So today I created a simple python script to bridge serial gateway with mqtt bus on my RPI:
https://github.com/mczerski/MySensorsSerial2MQTTThis is because I already use spi for nrf24 module mounted on a custom pcb so there is no room for another spi device.
