What did you build today (Pictures) ?

[nagelc]

I've had surprisingly good luck buying cheap parts from Ali-express, but not this time. I bought an NRF52832 iBeacon that supposedly had an SHT30 temperature sensor and KX022 accelerometer. When the parts arrived, neither of those parts were populated. All the beacon has is a push button.

I was able to program it to work with MySensors, however. With only SWIO and SWCLK (no txt out), I took @scalz advice (in another topic) and used a J-Link EDU Mini so I could use the RTT app to get printf style debugging. That worked nicely and I learned a new tool.

Perhaps I can use the iBeacon button for a remote.

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

Another 8x8 matrix based display...
This is not a real project, just a try to hide the LEDs for better WAF.
Print still needs some impovements, but from a little distance you can't see the details.

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.

Wow. All these recent creations are so professional. Really nice!

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).

@berkseo Cool!

[berkseo]

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

@berkseo 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.

@berkseo :smiley: I'm glad it was helpful. And now you're inspiring me back! That's a virtuous circle if ever there was one.

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

Not hardware though, but I'm working on my dashboard solution for a wallmounted tablet.

I kind of already have this working in angular, but lately I have switched to react (joined a new project at work where they use react for frontend development), so wanted to see how "easy" it would be to create a something similar to my angular dashboard, but in react instead.

Made a small screencast of the dashboard, and are now playing around with "fully kiosk browser" on an old android tablet. Next step is to create a wooden frame, so it doesn't look like a tablet that is mounted on the wall (for WAF'ines).

All data, except weather forecast and channel lists, is from my mqtt broker, where I use mqtt over websockets.I have a bunch of python scripts, and a node-red instance, to wrap things up for the display, and also do a lot of magical stuff, like turning on TV and amplifiers automatically when casting youtube, and then turn the TV etc. off again, when I haven't streamed anything for a couple of minutes. (So the kids doesn't forget to turn off the TV when they're finished watching cartoons)

Today i fired up my controller after 6 months houserenovation. Upgraded to new 2.3 version and instantly some old nodes started reporting again 😀. Yes, there were some without battery but several temp and binary nodes survived 6 months without supervision.

[zboblamont]

@sundberg84 Out of curiosity, did you have battery powered Nodes trying to contact a dead controller or did you shut them all down?

When the Controller here died in June/July, the hit on Node voltage was quite spectacular compared to normal decay, in this instance the gas meter which was only supplying hot water and cooking...

Sigh, this is on my todo list for a long time. I have a working solution with imperihome (gateway to imperihome implemented in node-red) but never get to mount the tablet. :(

Second sigh.... popularity of angular seems to decrease. Do I have to learn another framework?

Third sigh :) I like your chosen architecture except for the decision using websockets. (It is neither nice from a security standpoint nor is it proxy friendly, but who cares in a closed home enviroment.)

I really like your project. Maybe you can publish some react code? (Then I can try t understand another ui framework...)

After 4 months of finishing the new house, i finally started to build in my sensors :)

Do need to build a new repeater, since a part of the sensors are out of reach.

I was forced over to react, as the new project I was assigned to is using it (one of the downsides / luxuries of being in a large corporation). But yes, "Another framework". I can't decide if react is better than angular though. It's not as strict as angular on how to design things, but then the "strictiness" could be one of the strengths of angular.. I have experienced it a couple of times, where there are a lot of different ways to accomplish the same thing in react, so it's a bit harder to find the "Best way (tm)", whereas for angular it's a bit more strict path to implementations.

for the websockets, there might be security issues with it but if you want to have an open connection where you push data to the client, you don't have that many options available. I have thought about ditching mqtt for the frontend, and implement my own (websocket) protocol. Mainly to limit access to my mqtt broker, but there is only so many hours a day, and work, wife, kids etc. all want a part of them.. :)

The project is already on github, don't expect anything fancy though..
