@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

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?

@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.

Hi there! I need to buy some PCBs on Dirty PCBs but the URL http://dirtypcbs.com/view.php?share=13847&accesskey= seems broken. Any ideas? Thanks!

[m26872]

@รอเรือ Apparently they've moved to a new site. Perhaps you can try this link: http://dev.dirtypcbs.com/store/designer/details/m26872/663/myslim2aabatterynodepcbv2-0panelized

I think you must have a user account and login first. Please report back if it's working or not.

Edit: Wrong link the first time.

Thanks @m26872

That link didn't work either. However, by browsing all the shared PCBs I found this URL That link is accessible without logging in first.

Cheers

@รอเรือ Thanks a lot! All links are now changed.

Hey im building my first slim node and i wonder if someone has a sketch for 2 reed switches? i have found the sketch for only 1 reed switch in this thread. Im going to use it for my mailbox. How long do u think it can run on 2x aa batteries?
Do i have to add 2x 10M resistors? or doesnt it work with external resistors then using more then 1 reed switch?

[m26872]

@Eawo The example sketch should fit your needs. link Change the pull-ups activation to Low if you use external ones.
I'd expect battery life 5-10 years depending on things such mailbox opening frequency, use of heartbeat signal, battery self discharge and climate.

[m26872]

@Eawo Using internal resistors will only give you a few months battery time. One external pull-up for each switch will work and 1M resistors or any arbitrary "high" value is just as good.

[Eawo]

Thanks
ok now my problem is uploading the sketch it wont work on 1mhz bootloader i tried both a and b hex and the 2 diffrent Board.txt.
I get it to work with the 8Mhz breadboard bootloader.
But then using 1mhz bootloaders it always timesout

[Eawo]

after a few hours frustration i went donwstars grabbed 2x new atmega328p breadboards and wolla everything works :). I Think i burned my first to putting them in the socket wrong.
