What did you build today (Pictures) ?

@Nca78 nice :+1: it looks like familiar to me, i don't know why ;) I agree with you, I prefer rounded square shape as it fits more easily everywhere than circles

Not sure which one you're talking about, as it's some kind of child between @NeverDie 's board (same nrf51 module and small size) and your aeos (shape, on board sensors). But it's more like a challenge to me, make the smallest board possible (22*22mm) with as many sensors as possible (at the moment, door, TH, light, accelerometer) and I have a bit of margin to add more like the leak detection from @NeverDie it's really nice to be able to do it with such a tiny sensor.
I'll do a more complete and flexible 33 board later, I will try to make it some kind of a hand-solderable version of aeos ;) -
As far as minimizing size goes, I think you're right: square (or some kind of rectangle) is going to be better. I end up throwing away a lot of useable space going from square to circle, which, unfortunately, forced me into increasing the diameter (i.e. the size). So, in the end, square/rectangular is probably better. :) I think the allure of the circle is to try to fit the whole thing perfectly onto a coincell (which acts as a kind of limit on how small you can ultimately go), but unfortunately that can't happen with any of the coincell holders I've seen so far....

@Nca78
It was just a private joke :) If I inspire some people, then I'm glad! Because like you said, aeos is different (better mcu, more ios&sensors, and latest unpublished revision is..more generous).But, if you're trying to make a "aeos" (same sensors for instance) in future, then i don't get the point..why reinventing the wheel? Your board has qfn/dfn footprints too, so I don't see how it's easier to handsolder.
If this is related to Ic's price, there are lot of different ways to get them cheaper.You should maybe use stencils (maybe you already do it) that will save your day ;)
Keep the good work
@NeverDie yep, agree with you

@scalz We're not going to get much software being written (such as, for instance, an OTA booloader that we can all use or cool self-destructing crypto wizardy) until there's worthwhile nRF5 hardware available, so anything you can do to speed up the release of your designs would really help. I've been trying to Johnny Appleseed this, without getting much apparent traction on people adopting it. People seem to like your stuff, which looks very professional. If you can, try to make it available so people can start writing software, integrating it, etc. As the saying goes, a rising tide lifts all boats. :)

I posted a lot of nRF5 PCB's hoping that others would find some appealing and jump on the nRF5 bandwagon, but so far not much seems to have happened. Aside from some helpful feedback/suggestions from @nca78, I'm not really any better off than if I hadn't bothered. I'm not sure what motivates other PCB posters, but the feedback/suggestions have been the only real payoff for me. Unfortunately, most PCB postings have garnered zero, even if there appear to have been a lot of downloads.

@NeverDie @scalz To get the nRF5 series adopted by MySensors and its users I think we should start with a single board. We have to make sure it is easy to obtain/replicate (by using a ready available module, or using a hardware partner where people can just order the board) and supply the required getting started docs.
I really appreciate all the work done on the nRF5 support, but now we have to take the leap from prototype to 'production' to get it adopted by the community.http://yveaux.blogspot.nl

I think that's a good idea. A standardized reference platform would really help in building some forward momentum. How about you start a thread saying exactly what it is that you'd want the board to be like, and maybe it will gather some consensus and someone will make it. Like I say, I've launched numerous trial balloons, and it's just not an efficient way to get there from here. My guess is it will be some kind of multi-sensor board, maybe even the same as what @scalz and/or @nca78 are already doing.

As you say I don't want to reinvent the wheel, especially one that'll look square compared to yours :D
But I think it's important we still have a DIY option available for those who don't like soldering LGA or 0402, an equivalent of using the pro mini for the nrf5 world. -
This sunday a friend of mine and I did not know what to build. So we decided to use a project designed by @Yveaux
SourceI received 2 new CDEByte antennas that needed a range test. As I live in a mansion.... Next to a park we figured out that walking 1 degrees outside would be an excellent time to do a range test. It was not raining so.....
Our conclusion would be:
- Cheap ass NRF... good enough for indoor usage.. if it can mesh.
- Cheap ass Amplified NRF.. good enough in the house, needs a bit more space and power, but works quite well.
- CDEByte... not cheap.. but man my hands were freezing outside due to the long range.. And according to @Yveaux we could achieve a higher range if we would have set the power to MAX... During testing this was MIN.

Over the weekend I hacked the previously battery powered Minecraft lights in the Minecraft bedroom (doesn't everyone have one?). Now there's no more replacing batteries and OpenHAB controls include On, Off, Brightness and Flame Flicker.
This is the reason I was asking about establishing power distribution in the attic. I've decided to distribute 12v and drop to 5 or 3.3 only as needed.

Received the PCB today, so I put together this leak detector for testing:
Looks as though some of the physical clearance tolerances are a bit tight, so I'll have to do another spin after changing the PCB layout. Some Kapton tape will compensate for now and allow for some initial testing. -
Not MySensors, but related. Power over Ethernet (802.3af compliant) addon for the raspberry pi zero. I plan to use this for high power & high reliability devices where wireless will not work.
Top one is a higher power version, bottom one just uses an off the shelf regulator.
Currently these just have some IR LED's to control IR devices.

@SquareKinematics
Very useful to have. Not sure if you're aware, but you can buy PoE power adapters off the shelf. Even Amazon sells them. You select the output voltage you want with a slide switch. -

Jolly jolly.. wel actually no....
We have had wet feet from the central heating system serveral times now around Christmas or New Year.
Causing a wet floor and other possible disasters. Yes I know.. A Central Heating Mechanism should not leak, you could try putting a bucket underneath... But that is not 'that home automation' smart that I was looking for.So to detect a leakage.... I came up with this some time ago.
Pretty standard, a few wires... a Mysensors Node... and Pushover to send me urgens notifications about the leakge.
link url))And ladies and gentlemen it actually works as you can see in the pushover sreenshot, it kicked off today.

@sincze You could also put some salt into your tray for added conductivity when things get wet.

@neverdie Great tip, this will resolve in even a quicker response during a flood right?. I already added toilet paper as cover for a smooth moist/water distribution. Lets add some salt to that and hopefully never see an error message again. But I wont bet a bitcoin on that ;-).. Happy with this cheap solution.
