My Slim 2AA Battery Node

@carmelo42
Thanks for your support by ordering. I actually recieved another 50+ share credit transfer from DirtyPCBs today. It'll be donated to MySensors right away.

If you look at post 116 you'll see the I used a 10Mohm pull-up between Vcc and atmega input pin. Reed switch connects between Gnd and input pin.

Thanks to you for providing us theses files :)

Ok, my mistake (I juste received my 10 MOhm resistor ;)
Perfect, I just have to wait now for the little yellow packet ;)

[carleki]

I have received yesterday my little packet from DirtyPCB :)
11 PCBs, so 33 sensors :)

I'm just wondering where the C5 capactior will go on the board .. Can't figure out :(

@carmelo42: maybe this helps, all Cs and the R assembled!

ups... C5 is also not there on my board,it shoud be parallel to C4!

is your sensor working without C5 ?

[carleki]

@m26872 is it possible to send the sketch in the atmega on board ? using an FTDI serial/usb ?

[jeti]

@carmelo42 yes

@carmelo42 yes

I have this serial/usb adapter :

Can you tell me how I connect it to my node ? (noob question I guess ... but I don't want to burn my node :( )

I have found the answer myself with the schematic ;)

Have you ever tried to power the node with 1 x CR2032 battery ?

I have tried, but the node doesn't send anything further than 5 meters ...

I would like to know if your nodes are working all fine. I have the problem that my nodes freeze after a day or sometimes after a week.

[carleki]

@siod my temperature nodes work good, but my relay one doesn't work :'(

Do you have any logs when it freezes ?

[siod]

@carmelo42 no, unfortunately I don´t have any logs, any idea how to create logs?

maybe if you keep your node connected to your computer with USB to serial adapter ?

[siod]

mmh, no, that would mean I would have to run my computer for maybe 2 weeks 24/7...

I guess it has somehting to do with the sleep function, the device seems to nat wake up after a while for some reason

[dpressle]

So i got the boards and build them and they work perfect.

One thing i couldn't figure out is why do i get relatively high current consumption, when the node is sleeping i get 1.5mA and not 5.8uA as in mentioned in this post.

I use 8MHz internal clock and the sleep function and nothing is connected to the node.

Can someone help?

[AWI]

@dpressle Can you post the sketch?

[dpressle]

Thanks, i see its 6.8 uA now, i had something wrong with my measurements :disappointed:

It took me a while, but I just figured out how to get a bootloader burned onto the chip and I'm ready to make my slim nodes! Which board type in Arduino IDE do I use to program the chip once I'm using the 6 pin header after it's installed in the PCB?

[m26872]

@JonnyDev13 Make a new board type by editing "boards.txt". There's an example in the first post.
