@ceech thanks for the board - arrived via eBay today! Looking forward to tinkering!

nutcracker

@derwish ok... so what versions of the software do I need to have installed to ensure compatibility with MyNodes...? (I thought I had already tried rc1). Thanks.

nutcracker

Thanks derwish!

nutcracker

Thanks derwish.... any ETA on that ?

Have made some progress... by following the instructions here...
https://github.com/lluppes/pisharp

However, I'm now stumped with an error to do with libuv.

Welcome to MyNodes.NET.
Please configure the system in the web interface.

System.DllNotFoundException: libuv

Hi,

Has anyone had any luck in attempting to do the above? I've tried to follow the instructions on the website but the download link doesn't work (http://docs.asp.net/en/latest/getting-started/installing-on-linux.html).

I've tried installing alternatives but no luck - issues with ARM/Intel compatibility... what am I doing wrong?

Thanks

My graph output when using Datamine and the new MySensors Sensebender boards...

nutcracker

Thanks @hek, I also realised my mistake once I retraced my steps...I hadn't scrolled down fully on that screenshot that shows the Sensebender Micro board... I think what through me is that screenshot also shows a "dot" against another board - the Arduino Micro board...and I was selecting that... duh! (may be worth changing the screenshot? ;))

Anyway, thanks for your help...sketch uploaded perfectly after that!

Hi @hek, I've never had to change the programmer setting before... I've changed it to USBasp and re-uploaded but same error. I've always used the menu options Sketch=>Upload to upload a sketch to the board. Should I be using Sketch=>Upload via programmer for this micro board ? If so, that fails too but something to do with it not being able to find the USB device.

Thanks @hek. I've had to run Arduino on Windows before because of compatibility issues with certain chip sets on Arduino boards and I didn't fancy running unsigned drivers on my Mac to resolve... I'm able to upload sketches to other boards with no issues.

That said, I've updated Arduino to 1.6.5 on my Mac and have attempted to upload the default Sensebendermicro.ino sketch to the micro with a similar error:

Hi,

I've received some boards and all working good.

I'd like to upload a new sketch to the Sensebender Micro board and I'm attempting to do this via the FTDI FT232RL USB to TTL serial converter adapter that I purchased here (http://www.ebay.co.uk/itm/221552218333).

Could someone kindly confirm the pin to pin mapping between the FTDI board and the Senseboard Micro as when I attempt to upload I receive the message:

   Programmer Type : butterfly
         Description     : Atmel AppNote AVR109 Boot Loader

I'm using Arduino 1.6.5 running on Windows 8.1 (inside parallels on a Mac).

Any ideas?

Thank you

Hi @Gambituk,

The original battery pack (10000mAh unit sold as 100000mAh :)) as well as another that I've borrowed (9000mAh) work as designed, e.g. able to charge my iPhone with no problems... However, when you plug just the Arduino board via USB into the battery pack, they don't...which is real shame as this would have been ideal for my project.

Waiting to see what happens with the MySensor board (@axillent) that are being discussed and close to finalising as may be a AA battery, NRF24L01+PA+LNA SMA antenna and ability to have a couple of sensors is all I really need...

@tbowmo

Hi,

So I've investigated my sensor setup a little further...unfortunately in the process I accidentally shorted the power connectors on the Nano so now it doesn't work so well...leave that for another time!

I have a replacement that was on my original prototype connected to breadboard so was a little more careful in measuring voltage - on the Nano and on the step down board. I'm reading 4.8volts which I believe is to be expected.

I also changed to an alternative battery source but this demonstrated the same problem.

However, what I did discover after replacing some of the components to assist in eliminating what was causing the voltage to drop off is that** if I just have a very simple connection between the Nano and the battery (so literally only connected by the USB cable), I see the same thing - that the Nano powers itself off after 15-20 seconds**...

So does that imply that I've a duff Nano board...?

Anyone else have this board that can confirm a similar behaviour...?

To be clear, this is a Nano DCCduino with 5v, 3.3v connections powered by USB (http://www.ebay.co.uk/itm/301449586123). I also have a Nano v3 (http://www.ebay.com/itm/130977189883) and that too powers down when connected to a battery via USB! No one else seen this...??

Nutz

nutcracker

Yeah...I'm coming to the same conclusion that the typo exists in the description and the model number...

Either way, I've charged the battery up and connected it to the sensor yet it powers down after 15-20 seconds... Anyone have any ideas why? I can connect the battery to other electrical equipment (e.g. my controller) and that works fine....

Nutz

nutcracker

Yeah, I guess it sounded too good to be true!
I've contacted them anyway for clarification and I should be able to raise a dispute and get my money back (it wasn't that expensive and no doubt can still be used...).

Its still early days for me so getting familiar with electronics again and playing with Arduino's is fun...and certainly for the moment, 5V works for me...but I hear what your saying. Looking forward to the new boards that will be available hopefully soon via MySensors to allow further experimentation in that direction with AA batteries...

Yes the distance between the controller and sensor is pretty large and the standard NRF24L01+ units couldn't handle it.

Hi,

I had wondered that myself prior to purchasing but having seen similar battery capacities on the AliExpress website, presumed it was correct... Looking now, I think it could still be although the picture says different (description and model number state 100000mah).

This is the model that I purchased: http://www.aliexpress.com/item/100-original-power-bank-ultra-thin-samsung-Mobile-phone-power-100000-mAh-external-battery-portable-charger/32273198121.html

They also do a 120000mah version as well...similar physical size: http://www.aliexpress.com/item/Portable-Battery-Charger-120000mAH-Thin-External-Battery-Power-Bank-for-philips-samsung-S4-iphone-6-5s/32271404267.html

I'll leave my unit charging overnight and see what happens tomorrow...suspect that there may not be enough juice to run the sensor...

Hi,

I'm building a MySensors postbox sensor that will sit inside our postbox at the end of the drive and alert us when post has been delivered.

The sensor has been running in 'beta' for a few weeks powered by my Mac USB port. The controller is based on the Arduino Uno with ethernet shield and NRF24L01+PA+LNA SMA antenna. All working perfectly!

Now that my China shipment of a 100000mah battery has arrived, time to move onto the next stage and power the sensor by battery.

The postbox sensor consists of the following items:

Mini USB Nano v3 ATmega328P 5V FT232RL (Arduino)
SR-501 (motion sensor)
DS18B20 (digital temperature)
NRF24L01+PA+LNA SMA antenna wireless receiver (with 4.7uF cap)
8 pin socket adaptor for NRF24L01+ (5v to 3.3v step down)

The battery provides 5v via 1A and 2.1A USB connectors. The problem that I'm having is being able to power the sensor. It will initially be powered for approx. 15-20 seconds and then will switch off. This appears to be consistent each time.

If I power the MySensors ethernet controller via the battery, it remains powered and doesn't switch off. I therefore don't think the problem is with the battery but may be with the design of my sensor in that may be its not drawing sufficient current that makes the battery think nothing is connected and therefore decides to switch off.

I did change my sketch so that it didn't power on/off the temperature device (so would be powered all the time) but this didn't make any difference.

So is it possible that the external battery is switching off because not enough current is being drawn from it? Anything that I can do to confirm this? (note, a novice with electronics...but I get by! ;-)).

Update: It's possible that the battery is not fully charged...I'll stick a voltmeter over it first to see what its currently holding and may be a 12hr charge will fix the issue...??

Cheers,

Nutz
