Wireless expansion module for very cheap soil moisture sensor from Aliexpress

https://youtu.be/Toto1Cw4QBo

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

@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).

@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)

Almost finished one of my projects. The test sketch showed that HW works as it should. Now i need to make good software.

Another one of my brand new device is ready, today I finished the case for this device. This is a motion sensor on the S16-L221D-2. Also added a temperature and humidity sensor, it can be sht20-21, si7020-21, hd 1080, perhaps something else, now there are many sensors in such cases. Powered by a "nuclear" battery 2/AA (14250) 3.6 V. Powered by a chip nRF52811. I added support for this chip to the sandeepmistry boards.

Soon this sensor will be available at openhardware.io

@monte said in What did you build today (Pictures) ?:

nice piece! Do you mean accelerometer for an encoder, or a physical one? And if the latter, what for is it supposed to be used?

I think the use cases quite a lot, I want to implement double tap. For example, there is a dimmable lamp with switching to cold and warm light. Here with the help of a double tap you can control the switch from cold to warm and back. In any case, I think this is a good extension of the functionality.

@neverdie Thanks for rating. Especially pleased, so as nRF52 for me began with Your those on this forum.

@scalz said in HALO : ESP32 multi transport GW/Bridge for Mysensors:

the webapp was great, but I converted it to native crossplatform app for better versatility&perf, so I can use one app for my devices, like Ethernet for HALO etc, or Serial for my other Janus gw dongle, bluetooth..
To be honest, I've not updated anything yet for a few reasons, like very little spare time for a public release + support for such "big" project. (easier to handle local projects).
Sorry, still no eta for the moment..

It is clear that there is not enough time. But this project can become popular. That's what's missing MySensors. ...This void must be filled.

Yesterday I finished my new project. This is motion sensor (S16-L201D) + light sensor (MAX44009) + temperature and humidity sensor (SI7020). Рowered by nRF52840.

Is there any fresh news on this project?

@franz-unix said in Printing enclosures with SLA printers.:

The "marble" case is very cool! The filament is easy to print or requires some special parameters? For example in this days I'm fighting with a wood filament, below

I did not print such cases myself, these photos were sent to me. But I can find out about the printing settings for the marble filament.

...The lamp looks cool

@neverdie said in Printing enclosures with SLA printers.:

Justs a thought, but now that mysensors has FOTA, then for projects which would have, say, 10+ years of battery life anyway, then for very little money one could simply acquire an assortment of silicone molds in various sizes and simply cast your project in polyurethane or polyester or some such epoxy rather than 3D print a box. I know that there's at least one guy, who builds sensors for deployment in wet caves, who has already been doing it for quite a while now. For outdoor sensors, they'd be completely weatherproof, and for indoor sensors, they would simply look cool. You could even get a nice smooth look in the cast object, just as you could with a box printed on an SLA printer.

What is this technology? Is it possible at home (in the garage:)) to make silicone molds? Have a description of the production process, an article or a video?
