@gohan it's fun to do projects together! We enjoyed it and I tried the water story to explain everything. Also some short instructions to solder the legs and not the solder itself... Now he is playing with it so a good result!

On the workbench today: My Lenovo laptop getting a wireless network card replacement.The old card was wonky. Sometimes it wouldn't allow any network activity for a minute or so. Sometimes it would allow traffic, but only at 1-2mbit. Sometimes, but very seldom, it would deliver the ~100mbit it was supposed to.
With the upgrade card (bought off Aliexpress of course ;-) ) it delivers 40 megabytes per second when copying files from my desktop, and has been able to sustain that speed for more than ten minutes straight so far (still testing). New life to my poor laptop!

I soldered together a prototyhpe for a small wireless temperature sensor powered by a CR2032 button cell:
It works!
-
Today I'm doing some small things... Changed the antenna on my RFM gw to a bigger one. These one works really well!! Highly recommend.
-
The version 1 board for my button cell TH sensor finally arrived today. Though now obsolete compared to the current Version 4, I put it together anyway, and it works just fine.
I'll be able to use the I2C connector to get the software working for the si7021 and BME280 TH boards, so I expect the firmware will be finalized and ready to install before the version 4 board even arrives. :) -

Time for the nrf24 to move over and my LoRa concentrator board to take its place on the lab RPi.
Why?

I envy your LoRaWAN gateway... so you will soon add this to TTN maps and show a new gateway in Sweden ;-) -
@bjacobse define soon... it has already been connected to ttn for 2 hours :-D
@mfalkvidd
Damn you're fast :-) -
Today I also started upgrading my Domoticz running Raspbian 7 (Wheezy) to Raspbian 9 (Stretch). I tried to do an in-place upgrade but the rpi wouldn't start after the upgrade so I had to start over on a clean Raspbian 9 image.
I took the chance to switch to f2fs for the root filesystem, which should make the SD card less susceptible to corruption. I used this guide and it worked, except that I also added discard to the fourth field in /etc/fstab and changed the sixth field to 0 to not fsck before boot.
When I wake up tomorrow, domoticz might have finished compiling.

Though not directly MySensors related, I am setting my 3D printer up with some lights to see my prints for my MySensors projects better when running a job. These are some white LED light assemblies that have been salvaged from some recycled document cameras. I built a simple 7805 regulator circuit to run them. The next step is to design and print some brackets and articulating arms to mount them to the printer.

@mfalkvidd ai ai. Yes. I was warned on the Domoticz website about the 'not being able to startup'. I was able to successfully update from Wheezy to Jessi. Skipped the Stretch part for now.
Just made some preparations for the new node that has to replace several individual nodes in the technical-room. (Control of WTW, Measurement of heating pipes of CV using Temperature Sensors, Leakage Detector of CV, Door Sensor and last but not least OTGW-Reset)
Could not complete the PCB due to some missing components. The Sketch is running fine on my NANO
Looks like a mess now, but this development PCB comes in quite handy. -
That was yesterday.. :blush:
@tekka and I tested some new features he made, so here was my humble and fun test setup
Of course the Halo GW didn't disappoint us! All boards (mixed mcus and radios nodes) were attacking it at an agressive rate (100ms rate), and there was no crash at all. Halo GW was laughing & kidding us saying "Please give me more, I like doing this" :) (but I was lazy to assemble more, there was 13 nodes on the table..).
Too strong @tekka ;) -
Here is my Wemos "Serial" wireless gateway that I just today put together and installed. Connects to Domoticz as an ethernet gateay over wi-fi. Uses a static IP address that I configured on the wi-fi router. By the way, it's powered (and physically supported) by an Ikea USB charger, as seen in the photo. :)
