My new arduino project wireless weather mini station with electronic ink display 2.9 inches (GDEH029A1), very low power consumption,compact size, housing with magnets. The device can use si7020 / 21, sht20 / 21, HTU20/21D or BME280 sensors. Use the MINEW MS50SFA RF module with nRF5210, nRF52811, nRF52832 chips, or the EBYTE E73 module with nRF52840 and nRF52833 chips. Soon to be available on openhardware.io

My new mini multi device on nRF52810, nRF52811, nRF52832 chips. Designed specifically for a very small case from Aliexpress. It works!!!
bme280, sht20/21, si7020/si7021, hdc1080, max40009, lis2dw12, lis2dh12, lmt01, reed switch, led + rgb led, user button and 6 analog pins, 6 digital pins with NFC.

I think this open source project is finished. This is a small air quality sensor. Quite a useful thing turned out for our not simple time.

Wireless expansion module for very cheap soil moisture sensor from Aliexpress :)
An updated version of my temperature and humidity sensor with e-ink. Now on nRF52840. Now it is not a module but a device in the case.
Replaced temperature sensor sht20 -- > > si7020
Added accelerometer.
In the near future the project will be posted updated on the website openhardware.io

Hello everyone. I want to show you my new device, battery powered air quality sensor. The device also has light, temperature, humidity, and atmospheric pressure sensors. I am currently testing the software.
@magpern said in 💬 EFEKTA Temp&Hum sensor(ver. nRF52832 )+E-Ink display:
Seriously!!!!!!!!!!!!! It cannot be true!!! I have just ordered PCBs and all needed stuff to assemble it, and now the code is gone!!! Please post the code again, or make it available on alternative sites.. please. It is hundreds of dollars to waste otherwise!
The project will remain open, like others. I was in a bad mood that day:)... The rules of the site administration are reasonable, and the decision to open the project was mine.

My new project is finished today and put to the tests. This is a continuation of my other project - Wireless Module for Capacitive Soil Moisture Sensor v1.2.

Today I finished printing the case. Turned out to node with sensor bme280 and e-ink display, running on nRF52840 from SKYLAB
In one of the photos still have the sensor with bme280 working on nrf52840 from EBYTE. ...This is the previous project.
upd.
Another project of mine, the second revision is finished today and put to the test. This is an encoder with accelerometer, powered by nRF52811 chip (datasheet).
The other day I received PCB of a long-awaited project. Yesterday and today, I soldered the device, designed and printed the case of the device. It works, wow!!!
My new project of a temperature and humidity sensor with an electronic ink display 1.02 Inch ( GDEW0102T4 ), very low power consumption, very small device.
And another of my completed projects is a mini weather station running on nRF52832 and nRF52840, you can install bme280 or si7021, htu21d. Powered by a single cr2450 battery. As always soon to be on openhardware.io

@nca78 said in What did you build today (Pictures) ?:
What resin do you use ? Can you share (by MP if you want) a screen capture in slicer to see how you print it (support etc).
Just bought a SLA printer and still learning, that would help me as I have similar enclosures to print.
Anycubic Resin. All my projects are always fully available on my github (Gerber, hull models, schematics, codes)
I just got an email. It was unexpected :). This project of an air quality sensor that works on Mysensors became one of the finalists Hackaday Prize Challenge 01: Rethink Displays.
Almost finished one of my projects. The test sketch showed that HW works as it should. Now i need to make good software.
