What did you build today (Pictures) ?

[dbemowsk]

Working on a smart clock project. Need to make some major code modifications to the example, but should work. I have a test sketch that just passes the time from the RTC to the display, so I know that is all working.

Last night I made a enclosure to my new outdoor weather station/node. It is made from 2x 70mm sewer pipe end caps and a small sewer pipe to keep them together. Works surprisingly great and looks good.
Now its painted black and drying - lets hope I can find any daylight this week and mount/deploy it.

@sundberg84 If this is going to be out in the sun, I would think you'd want it white. Black is going to heat up your electronics quite a bit.

[sundberg84]

@dbemowsk - No worries, no sun! All below a roof so I get shade all the day. The roof is black so I need it to blend in as well.

I soldered together the PCB I made for my RFM69 Pi Gateway. Next step is to put it in a nice enclosure

A set of Node-Red nodes to decode OpenTherm messages produced by thermostats and Central Heating systems: https://github.com/Yveaux/node-red-contrib-opentherm
It can e.g. replace the OpenTherm Monitor software from otgw by InfluxDB/Grafana :+1:

Not a MySensors project, but nice anyway ;-)

I did a quick port of my earlier project to make a breakout board for the BC832:

What's interesting about the BC832 is that it is a complete nRF52832 system: 32-bit ARM Cortex 4, wireless, flash, memory, RTC, and antenna, and the whole thing is smaller than a dime:

Of course, my ported breakout board, being as large as it is, doesn't do it justice. That's OK, though, because its main purpose is just to take the BC832 for a test drive.

Power (lower half) and external interfaces (upper half) PCB for my "entrance" MySensors node (unregulated voltage, +5V, +3.3V, doorbell detector, electronic door lock status, temperature, etc). I'm using conventional 220V=>6V transformers as main power supply and as simple 220V presence detector for doorbell.

[sundberg84]

Let me present - How NOT to deploy a MySensors Node! Here is how you do: 1) Skrew everything solid to a wall 2) Power it up and make sure you have shorted a SDA / GND or VCC on your BMP sensor just because you dont doublecheck the colors 3)Forget to enable # My debug 4)Fetch your last BMP sensor but drop it on the lawn (pitch dark outside) 5) Spend 30min with a flashligh in 5dgr C searching for the sensor and try it out once you find it. 6) Nothing works so Un-screw everything and connect it to FTDI inside at your computer, reupload the sketch with debug. - Now everything works fine (with the first sensor) for some unknown reason. 7) Skrew everything back again! 8) Find out the BMP sensor is not working 9) Debug Serial (atleast I got to use my new logger) 10) Find out a short on the MysX connector due to bent wire.

New and old sensor - side by side.

@sundberg84 poor guy... +1 for persistence though :smirk:

[NeverDie]

@sundberg84 Time for you to do a new PCB so you can get rid of all that wiring....

[sundberg84]

@NeverDie Im waiting for someone to create those MysX shields so I just can attach them to my EasyPCB.

[NeverDie]

@sundberg84 Where is the definitive description of MysX? Perhaps I might have a go at making some shields with it, if I knew what it was.

[mfalkvidd]

@NeverDie not sure if https://www.mysensors.org/hardware/mysx is definitive but it should be a good start

[NeverDie]

@mfalkvidd Wow, MYSX 2.6 is a 22 pin connector! That wouldn't be practical on a small shield (such as a pro mini size shield) I don't think.

[mfalkvidd]

@NeverDie from what I've understood, the idea is that you pick the lowest revision that can support the features you want. So you can select 8, 10, 12, 14, 16, 20 or 22 pins.

[gohan]

Non the less, if we start having a more standardized environment on the mysx connector, it would be best. But we are going OT.

[NeverDie]

Put together this pro mini nRF24 shield for testing...

[shabba]

@NeverDie Neat! All I need is a rfm69 version :-)
Where you get pcb?
