sensors in boxes

[Moshe Livne]

@GuyP PCB arrived from oshpark!

What capacitors did you use for the crystal? and what resistor for the dallas?

[GuyP]

Ok now I'm jealous.. that looks fantastic.

[Moshe Livne]

@GuyP It does... Now I realize that if I knew what I was doing (and I don't) it could probably be made smaller and no need for soldering at all.

Thanks! will let you know how it worked out. Might take a bit of time as I am now finishing my AirCon remote sensor.

@GuyP Can you post the 3d files for the box in original post if possible?

[GuyP]

Sure here you go..

TempSensorBase.stl

TempSensorTop.stl

@Moshe-Livne Any progress?
can you please explain how this pcb be smaller with no need for soldering
Where are you from?

[Moshe Livne]

@oded00 Still waiting for the 22pf capacitors...
It was made in resolution for home made PCBs and single layer. oshpark can make the lines much smaller and make more layers so there is no need for soldering the "red" lines. you still need to solder the components (nrf, capacitors etc)
I live in NZ

@GuyP If I order this brd files online, I assume that I need to remove the red lines from the top layer? Or maybe reroute them if possible? Looks like some short circuit connections.

[Moshe Livne]

@pjeterinfo Oh I didn't notice them. Darn, and I soldered the wires...

[GuyP]

Yes You'll want to remove or reroute them. I was only think of a single layer board so those are link wires. Sorry I should have talked about those.

[pjeterinfo]

I order a few with modified toplayer to fit all the "red" wires and removed 2mm of the board width.
tempsensor.brd

[GuyP]

Excellent...be careful, not to remove too much from the right side, as the radio transmitter will over hang which makes it harder to fit in a box.

What is the name for this board on OSHpark? I would like to order 3 of these boards myself

@mntlvr don't use this as it has shorts. Use the corrected one someone posted a few comments back

Thanks Moshe-Livne but I can't find any comments on this posting about anyone buying boards that work can you help with this or is it best just to make your own?

Just upload the brd file pjeterinfo posted

[pjeterinfo]

Use it on your own risk, it's nog yet arrived and thus not tested ;-)

[Moshe Livne]

@pjeterinfo I still need to cut the traces on mine....

[pjeterinfo]

All parts received and programmed using a pro mini, man that's frustrating ;-) . But works great..

Hi,
Nice little board.

Do you know how long does the dallas temp sensor keeps working on?
I ask this because its minumun supply voltage is 3.0V and you are feeding the board exactly with that.
So, what happens when the battery voltage get a bit below 3.0V?

Thanks, regards.
