my guess was bang on the number - just out on the units!

Just a bit out from your initial guess then  :laugh: What kind of frame do you fly with?

@Liam - no, absolutely fine.  had another couple of flights with it afterwards -  :laugh:

Black vortex batery monitor

Previous topic - Next topic


I have just been configuring my BV with MP and have a small question. The battery voltage displayed is the voltage of the board ( I think?)
what I require is on the screen display is the voltage of the battery.  I also read some info on the arducopter wiki site about some add-ons
that are available for the arducopter project.
Any thoughts? anybody?



I think to display the voltage of your battery you need some add on board but I have never used one before so dont really know the details, I think it divides down the voltage and then connects to the BV,
You can also connect a sonar module to the black vortex for low level altitude hold, it works better than the built in baro but only works up to about 3m, you can find the module here http://www.goodluckbuy.com/ultrasonic-wave-detector-ranging-module-distance-sensor.html
You can also connect something for telemetry (wireless connection) you can buy the xbbe's for this but they are expensive a cheaper alternative the apc230 can be found here http://www.goodluckbuy.com/index.php?target=products&mode=search&subcats=Y&type=extended&avail=Y&pshort=Y&pfull=Y&pname=Y&pkeywords=Y&cid=0&q=apc230&x=0&y=0 I use a slightly earlier version of this the apc220 its a little bit slower but works ok and allows you to connect to your copter via the planner wire free  ~~


Thanks for the info.  I have already purchased both items mentioned in your post.  I will be adding them in due course as I become more familiar with the general setup of the BV.  This really is a long project for me as I get more out of the building than the flying.  If I come across something that does the job of battery monitoring I will give it a post.

It looks like the hardware used is call the AttoPilot voltage and current sensor
you can get them from here http://www.sparkfun.com/products/9028

or here http://www.coolcomponents.co.uk/catalog/attopilot-voltage-current-sense-breakout-p-433.html





We just need to know how to connect it to the black vortex now  :rolleyes:


That seems like just what I am looking for if it can be make to talk to the BV.  Hopefully some brave soul out there will sort it out!



From what Ive seen and read it has to connect to the analogue input pins which the black vortex has 5 of them not being used but I don't know which should or could be used, sg1anubis seems to be pretty clued up over on rcg about the code he might know the answer  ;)


I have sent Adam a message on his web site ( I donated some time ago so I do not feel too bad :smiley:).  See what he comes up with



I received a reply from Adam and I checked with him to make sure that I could paste it here.  So here it is
