Caps ordered. Yes there is plenty of space to put the capacitor on that is part of the ground plane. Just some fiddly soldering with a bit of fine wire to get to pin 6 from the capacitor. you can fit the 0805 directly on the GND+filter pin of the acs712. So no wires needed In order to reset the con...

For the arduino boards i like these here: http://www.ebay.de/itm/230935770283?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649&clk_rvr_id=483279605223 the advantage is that they are especially thin (0.8mm). it really makes a different. and if you solder the 2 boards back to back you can bu...

What is the type number of the 47nF capacitor that will fit between the pins of the chip? ok... that was more of an illustration. My capacitor is slightly bigger and uses a bit more space than the 2 pins. I am using the 0805 types i had here from an assortment i bought from ebay. As much as I would...

Nice! i like it!
But audio has to be added to that board

yeah.. it can be a rain dance sometimes

Maybe they had an idea of energy recuperation in mind.... Recharge the battery by using prob or air brakes.. or even solar wings?

It should work out of the box with the D-Series receivers. I'm currently rewriting parts of the code to make the telemetry code more modular. By doing this we will be able to develop new classes for other telemetry modules. There s already a branch for Jeti telemetry on the google code page, which h...

One tip for the chinese ACS-712 modules: The modules i bought from various chinese ebay sellers all came without a filter capacitor installed. The datasheet documents the possibility to add a filter capacitor to the circuit. I manually soldered a small 47nF SMD capacitor directly on the 2 pins GND a...

but you are not alone with the problem: http://openrcforums.com/forum/viewtopic ... 100#p32113

You might want to consider selling the FAS40 and building yourself an openXvario..(maybe without the vario part) you could do all the calibration you want that way.
there will be a new version of it soon that can be run without the vario part. that one could be built for parts woth 8$....

Hi Leo! i raised that issue.. the current resolution in the telemetry protocoll is in steps of 0.1A. this only creates problems in really low Ampere situations. for a copter this should not be relevant. you need to consider that charging discharging a battery always has some loss of energy. so it is...

Got a mail from microtechnics.eu today.. "According to last communication received from FrSKY, first batch should be available here around middle of June. All the reservations received for the first batch will be fulfilled, including yours if you want. (plus some reservations made for the secon...

you can use any of the ACS712 sensors like e.g.: 30A: http://www.ebay.com/itm/New-High-Quality-30A-Range-Current-Sensor-Module-ACS712-Module-ER99-/111069234299?pt=LH_DefaultDomain_0&hash=item19dc3e047b or 5A ( for small gliders like DLG's ) http://www.ebay.com/itm/5A-range-Current-Sensor-Module-...

Hi Heath, i don't think anybody did that yet. those who build it probably use it with the 9X or Jeti telemetry, in 9x you have the ALT+ showing you the max Alt. So this would be helpfull if you use it without Telemetry. Implementing should be quite easy, but i am rewriting the code currently in orde...

You just didn't knew yet that you need voice in your 9x ;-) It's one of the best features in my opinion. And it changes the rc experience quite a bit especially combined with telemetry data.. I'm using a sky9x board... but it will be hard to find one currently. Just search the forum and you will fin...

i like green Thx

I found the ACS713ELCTR-30A-T on ebay for a little bit more than 3€ + shipping. Its very similar to the ACS712 used in the modules i used so far. The main difference is that it is only usable to measure DC currents. (the ACS712 was for ACDC \w/) Now to the good things: it is pin compatible it is uni...

But till you found that setting of yours it was sure a helpfull feature ;-) and that setting "maximum sensitivity" is good for you, but i bet others are getting nervous already if there is just on false indication. ;-) i like settings around 200... with limits in the positive like 0.1 and ...

sure why not not that im good at cleaning things up, but i already been stuck not being able to move things outside of my area.....

i really need to cleanup some topics

i've got ten fingers that convinced me to count in decimal ;-) and honestly i don't like mixing units just because they exist. If theres another good reason despite some traditional conservative ones... i would be curious ;-) in case i loose 2 fingers in the future i might have to change to octal th...

Would you like to add that one to the Wiki? i am myself looking for something like that, but didn't find the time to work on it

OK, this topic can be used for "longer" off topic discussions

@mutchy: i installed a push button on the bottom of my TX (top right corner connected to the trainer switch which has been replaced by a rotary encoder...) which will give me the current altitude via voice. this way i can choose how often i want to get that information. this is additional to the var...

Thanks for the hint. Did some digging in the Taranis manual and got it working. Went to "Custom Function" menu, set the switch to be "ON" and the "Function" to be "Vaio" and now I have tones. you can choose any switch instead of "ON"... not that i d...

I'll assist... no worries

yes... gravity is a bitch sometimes... ;-) but if you could do some tests on er9x that would be great. No need to test it in the air... we would just need to know first if all the telemetry field that the oXv can transmit will be received the same way as in openTX. so it would involve going through ...

Hi Mike, yes the current metering uses the standard FRSky ID of the FAS sensors. (0X28). if the optional mAh metering should be used ,that value is being written to the DIST field using ID 0x3C, which is probably not a standard field. But i can create some additional optional define statements to wr...

i would always prefer a solution that works for all modells of the 9x. the more potential target transmitters there are out there, the more we can achieve by the work going into all these open projects.

Rainer.

I Just did another test with the capacity counting in a low current situation. test setup was generating a current between 100 and 200mA the current sensor was a ACS712 +-5A connected to my oXv the new function to calculate mAh in the oXv was active and transmits it output to the DIST field. the tes...
