Looks neat! How did you do the cutout of the sides of these enclosures?

No magic, this is the work of the CNC...)))

Today I had the ladder so I could get on the roof so while there I changed batteries on my rain node.

@sundberg84 But what did you build today? ;-)

[sundberg84]

@yveaux nothing that I can post here unfortunately... only a ladder for my cat 😂 non automated.

It's a breakout for a Fanstel BT832 (NRF52832). Two experiments with this board, still a work in progress:

• I wondered if it would be possible to hand solder to the LGA pads on the back of the BT832 using small plated thru holes (6 solder spots middle left in the first picture). Two pads connected. The rest did not. About what I expected.

• Using just the microprocessor of the BT832 to make a LoRa node. (NRF5 radio turned off). So far the Ra-01 is not initializing. Edit (10/8). The RA-01 now initializes. I needed to update the pin assignments in MyBoardNRF5.h.

Just pretend you have automated your cat. We can't control from here.

Colleagues!
I am writing in this thread, because here are the most active users of the forum and the system MySensors.:raised_hands:
Perhaps you can help me with the solution of my problem: Improvement Xiaomi smart kettle (I need help!)
Maybe you had similar projects...
Then, I can finally publish a new project in this thread. :v:

[Yveaux]

@vladimir please don't crosspost. Everybody is able to see the latest messages, so there is no need to point to your post from multiple threads.

[vladimir]

@yveaux Excuse me. I promise not to do it again!:man-gesturing-ok:

[sundberg84]

@Nca78 Well, i automated my cat door.

The rules are simple - keep it simple with one picture (or a few) with a small text including a small exp

sick of breadboard so made the gateway more permanent. added a nice dc plug to it after pic

[sundberg84]

Playing with how small I could create a EasyPCB if I only used SMD components and footprints for both RFM69 and Nrf24l01+... including MysX, Signing, Flash offcourse... and a coincell...

@sundberg84

cool, what dimensions are you down to now?

btw. what happened to the trace in lower right corner (the one that runs by the ISP connector)?

[sundberg84]

@tbowmo - Thanks!! :) 42mm diameter (round, but the 3d view doesnt show that).
The track - well, it seems like I can only get KiCad to make 45dgr tracks... need to investigate it its possible to make other tracks...

@sundberg84 you can also use smd crystal. They are cheaply available on aliexpress. Are you using 0603 caps and resistors?

[sundberg84]

@monte - 0805 res/caps, (for me easy to solder, while 0603 is possible but start to get hard).
I was thinking about SMD crystal but left it since i couldnt find a common size. Do you know a good size for SMD crystal (with multiple brands?) like 0805 or a good searchword? I found HC-49S but they are the same size as the ones with pins.

I recently hacked my Assa Abloy/Yale smart lock as it could only turn +-90° created a new washer ring, so it now can turn infinitely so it is usable to use a lock

What an inspiring thread!

@sundberg84 I've bought these 5032 crystals: https://www.aliexpress.com/item/Free-shipping-20pcs-16-000MHZ-16mhz-20pF-2Pin-5032-smd-quartz-resonator-Crystal/32821974003.html but there are plentiful other offers on aliexspress and/or ebay. This 5032 package seems to be the most common. There is another package with the same size but with 4 pins 2 of which are not connected, I bought them from my local distributor, while was waiting a package from aliexpress. But those with 4 pins are harder to solder (obviously) and I don't see any pros of using them.
The most suitable for hand soldering and easiest to find are these:
According to this image the ones I have are TX5 and TG5.
