What did you build today (Pictures) ?

[sundberg84]

@zboblamont its the one from mysensors store. I bought 10 and 8 of them is working.

Finally I finished my chicken coop door opening thingie :) A build that has taken way to much time to complete, and a few different directions.

Just as I was ready to install the thing, I discovered that the DC motor that I had bought for this, couldn't lift the gate. So I had to go scrap hunting, to find a larger motor for it.. Luckily I had a 24V motor from a broken garageport opener which chould be used at 12V.

Control box above the door, includes a PIR sensor in the lid.

the gate, a sheet of 3mm black acrylic "glass". I had a couple of reed relays in the parts bin, so I use those to detect positions of the gate.

The motor on is placed on the inside of the wall.

Field update of the firmware.. Should probably reflash the bootloader, to mysboot, so I can do it OTA..

and of course a small video of the in action

@tbowmo smooth! :+1:
That should keep the foxes out :fox_face:

[bjacobse]

@tbowmo Looks good

[tbowmo]

"funny" thing, that you first find all bugs after a more advanced node is deployed.. But after a couple of days debugging, with frequent firmware updates (opening the box, plugging in cables, and sitting with a laptop between all the chickens). I think that it is done now..

Firmware is here (if anyone is curios) https://github.com/tbowmo/chickenCoopFirmware

Hi all!

Today I eventually built my first MySensors device - Serial Gateway.

Now I'm testing it with OpenHab and working on first node - battery powered scene controller.

@tbowmo I've also been using MQTT and NodeRed as the routing solution for my home automation. I found that there was no default handling of ID_REQUEST messages which made configuring new nodes a manual process but eventually added that to my flows and now new nodes don't have to be configured at the Arduino end.
It would be nice to see more about your setup, more specifically about the dependencies in nodered-mysensors-flow/package.json on your github.

@chisight

Have you seen this thread: https://forum.mysensors.org/topic/9296/node-red-contrib-mysensors-release-thread ?

Basically these set of nodes includes a controller node, that handles mysensors ID assignments, and a couple of other basic controller features.

[chisight]

@tbowmo I had seen that thread. After importing your https://github.com/tbowmo/nodered-mysensors-flow, I think this is probably quite different from my approach, I've kept it all as flows without writing any new node types or adding dependencies beyond what is installed in Raspbian by default. At some point I'll get around to documenting and posting what I've done in NodeRed too, it's a pretty simple but surprisingly powerful tool.

[chisight]

My Node Red controller is closer to what FotoFieber did a couple years back but it's for 2.3.0 and MQTT. His project is at https://forum.mysensors.org/topic/700/node-red-as-controller/28 as well as various updates over time. It was good to see @FotoFieber's code as it showed me a few holes in what I've done so far.

[tbowmo]

@chisight

Well, node-red is powerful and you can do things without creating any new node-red nodes, but it makes life a lot easier (for me) when you can just pick an item from the palette, and hey-presto you have decoded the (serial/mqtt) mysensors message. Or pick another one, and you have a controller added, that can respond to ID requests.

Btw. the the github repository that you link to, was a bit outdated.. :) A lot of things have happened since I pushed last time.. (just pushed current node-red flow for reference)

So I finally finished my motion sensor project and it works :)
It will be published on OpenHardware.io soon :)

[rozpruwacz]

And also finished my toolkit library for MySensors for faster code developement (https://github.com/mczerski/MySensorsToolkit). Example projects (https://github.com/mczerski/MyMultiSensor).

@rozpruwacz nice & small motion sensor, good work!
Where did you get the swivel to mount it to the wall?

[rozpruwacz]

@Yveaux I get it from the polish suplier (https://hurtowniaimport.pl/291-bb1-uchwyt-magnetyczny-samochodowy-do-telefonu-gps.html) but if you google for "magnetic phone holder 360" You wil get similar mounts.

[rozpruwacz]

I found one on aliexpress: https://pl.aliexpress.com/item/GETIHU-360-Car-Magnetic-Phone-Holder-For-Phone-in-Car-Mount-Magnet-Universial-Mobile-Cell-Phone/32879720933.html?spm=a2g17.search0104.3.244.101611774LZhtS&ws_ab_test=searchweb0_0,searchweb201602_4_10152_10151_10065_10344_10068_10342_10343_10340_10341_10696_10084_10083_10618_10304_10307_10820_10821_10301_10843_10059_100031_10103_10624_10623_10622_10621_10620,searchweb201603_1,ppcSwitch_2&algo_expid=17a12b56-7a20-49df-aab1-45b5519746f0-29&algo_pvid=17a12b56-7a20-49df-aab1-45b5519746f0&priceBeautifyAB=0

Today I soldered the Velleman EDU09 oscilloscope kit. The kit is quite cheap (~50 EUR in local store). The specs aren't impressive (max 200kHz and min 100mV/division) but hopefully it can help me learn how to use a scope before I buy a real one.

[tbowmo]

Not at all mysensors related, but I have been busy building a bartop mame cabinet the last week or so.. Still mis a couple of details, but it is in a "playable" state right now.

The setup is using an old 19" lcd monitor that I had in surplus with a RPI-3B on the back, a couple of cheap Chinese arcade controllers, a partly homebuild audio hat for the rpi (adafruit i2s 3W amplifiers), and a switchmode capable of 5V @8A (if I remember right), and 12V @3A. So I have power for the marque lighting as well..

Only game available right now is Bubble Bobble, and the kids loves it (as seen in the video linked to below).

@tbowmo
Quite impressive arcade game
