Sensebender Micro

That ftdi connector could have some effect on the antenna. I specifically made the area below the antenna empty, so that it wouldn't make any problems with the antenna.

[Fabien]

So now the good news. I "repair" my 1st SenseBender (only two wire but one on the ATMega) and it works (with the same radio wich failed). I remove the FTDI header and everythings is ok. So now I'm sure the problem is the FTDI header near the antenna. And be carefull, we can have the same problem with battery for example. I suppose minimal distance is about 3.2 cm (lambda/4).
But now I have a question : How can I update sketch without header (0° header doesn't fit in case). OTA ? Is ther a tutorial for OTA update with out of the box SenseBenderMicro ?

Thank for your help !

I have the FTDI headers on the opposite site and I also get this transmission errors.
I ordered a new batch of NRF24L01+ modules and will check if the problem still exists.

I have my FTDI headers on the other side as well and have no transmission errors.
I am using genuine NRF+ radios though.
could be the fakes causing a problem

[tbowmo]

I have a male connector on my FTDI thingie, so I just put it in the mounting holes on the micro, and hold it to one of the sides, so it makes contact.

I tried uploading the sensebender sketch using 1.0.5-r2 with board config "pro mini 328 3.3V 8MHz". The si7021 doesn't work in this configuration, but I managed to get a sleep current of ~6.8uA

I can provide the binary output from the two IDE versions if someone can give me an indication where to find the build binaries.

I think it's better if we can get the intermediate asm file from the compiler chain. Will look at it tomorrow evening (I have closed my computer down for the evening today)

I have so far had no problems running my PIR sensors at 3.3v with the following hack.

You can not do this with all PIR Sensors from what I understand, but one of the ones listed in the MySensors store is what I've been using. Go down to the bottom of the article.

I just wanted to follow up and say thanks for the link/info
i was able to get that working.
surprised that they just don't offer a 3v pin.. it works great the way that link shows
Thanks again!

Has anybody built a box for the standard Sensebender Micro with 2 AA batteries yet.
I would like to get the .stl files if so
Thanks Doug

Hi Doug,

@ServiceXP has posted this one: http://forum.mysensors.org/topic/1566/mysensors-sensebender-micro-3dp-case

Has anyone been able to "Include" it to VERA UI7, My Sensebender borad is working fine according to the output from the Arduino terminal window - it request a node id, but will not "include". I'm using the default code already installed in Sensebender Micro board.

Yes, it works in UI7. Are you using the correct Vera-branch?

If somebody is looking for some Sensebenders. They are in sale currently for only 14$

Edit:

I thought I had paid 17$ but they were initially sold for 14$. Sorry.

I just order 4 new sensebender, NRF24L01+ (normal and PA+LNA), and Iboard for the gateway. Shiiping is quite expensive (about 31 $)

[tbowmo]

@Fabien

Did you choose DHL as shipping option?

[soward]

I just tried to order something from them and for some reason DHL is now the only available ( US ) shipping option, and it's quite expensive. The sensorbenders I ordered last month were ~$6 shipping, the other components I looked at today via DHL (similar size) were $46, so might be worth holding off a bit until they restore the air-mail option.

[hek]

$46 in shipping is a bit hefty. I'll check what's up with their air mail shipping.

[soward]

@hek I have seen it happen once before with them -- wait a few hours, or at most a day and it'll be corrected if history repeats...

[Fabien]

My last order have cheap shipping costs. But this time I buy lot of things, and shipping price is probably higher du to the weight.

@gloob You fell for the oldest marketing trick in the world. I also missed a heartbeat when pressing on the clearance banner and seeing sensebender there!!!
