What did you build today (Pictures) ?
-
My brand new device on nRF52840. It is a light and shock(vibration) sensor.
Two sensors are used, max44009 light sensor (1 ua) and lis2dw accelerometer (1 ua).
The light sensor measures in Lux.
The shock sensor has five levels of sensitivity.
Two modes of operation: main (working) mode and command reception mode.
The sensor accepts settings: the interval of sending data from the light sensor (in minutes), sending recalculated light data from Lux to watts per meter squared(on/off), the sensitivity level of the shock sensor(5 levels, 1 to 5)
Depending on which sensors are installed on the PCB, it can be used only as a light sensor, only as a shock sensor or both.
In the near future the project will be posted on openhardware.io

@berkseo this would also be good for monitoring when the trash cans get picked up by the garbage truck. If it has enough range that is. Of course that wouldn't apply to high rise dwellers, but for people in houses it would be a nice perk.

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

Amazing! 😃
The case is 3d printable?

This is made on SLA printer, but should normally print on FDM -

@berkseo I'm quite interested in a schematic view showing how the epaper gets wired up, because priced just by itself epaper seems like an affordable solution.
or
On the other hand, if one has to rely on adafruit or similar for an epaper breakout board to make use of it, the effective price jumps by around 5-6x or so.

iron and toner transfer, then etched and soldered and finally acrylic spray on cobber so it won't corrode

Hello, as it was getting seriously off topic, I moved the discussion related to SLA printing of enclosure to here :
https://forum.mysensors.org/topic/10815/printing-enclosures-with-sla-printersFeel free to suggest a better title.

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 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.
