Hi MrDespar. I did not want to affront you, but writing 'searching for this 0402 1Mohm smd resistor (and asked some friends) but there are hundreds of similar resistors with different voltages.' makes me think, you and 'your friends' have to really learn a lot, before putting hands on a PCB board, t...

I spent a couple of days searching for this 0402 1Mohm smd resistor (and asked some friends) but there are hundreds of similar resistors with different voltages. How do I select the right one (which voltage and stuff like that). Could you also help me find the C109, C115, C125 please, that would he...

frsky download websit there are firmware which conteims bin and Dfu files (bin for windows and Dfu for Mac) You have the newest version of openTX on your Taranis, so no sense to mess with those files. That are old openTX versions ... firmware xjt Whiche contains Frk files. That are firmware files f...

So, on your remark about the capacitor, João. Still have the test on the table here, The disk has 2 magnetos. Bildschirmfoto_2020-01-30_15-35-30.png I get 2 pulses per revolution. This is a pic with full speed with the 100 nF. Bildschirmfoto_2020-01-30_15-35-00.png And this without ... Bildschirmfot...

Jim, used a 100nF, not 10nf. Circuit -> https://i.pinimg.com/474x/3c/84/c3/3c84c3492331cfd3db17a22f92e9035f.jpg The oXs config for that test is attached. The hall sensor is connected to oXs and oXs is connected to the D4R-II and as you are sending data over to the D4R-II, the RX pin (r= receive) sho...

The A3144 have the sensor on their side, right? Yes, that is planar. From https://www.allegromicro.com/en/Insights-and-Innovations/Technical-Documents/Hall-Effect-Sensor-IC-Publications/Hall-Effect-IC-Applications-Guide#Q161 Planar and Vertical Hall Devices Planar and vertical sensors are based on ...

No problem. RPM with hall sensor and oXs. Those A3144 arrived today. Made a 'test-stand' with a bl motor and a disk with two magnetos. Had to put the A3144 90° angled in. Had to learn, that this sensor is a planar hall sensor. A vertical one would be better :( DSCF5074.JPG 'Electronic' for the A3144...

Was faster.

Ordered those here and shall run some tests.

Weather is bad and news tells me, we have climate, refugee and a FrSky crisis, I need some distraction

João, so here https://imgur.com/H5OATsTl.png -1- is the hall sensor, -2- the aluminum holder and -3- a disk (plastic?) with two holes with magnets. Makes sense. Sensor circuit just simple like that here? https://maker.pro/arduino/tutorial/how-to-use-a-hall-effect-sensor-with-arduino How did you test...

Jim, I only fly electric. And for that, I tested this solution with oXs under FrSky and Multiplex successfully. https://imgur.com/oJHD7B7l.png https://imgur.com/NhRCDTpl.png The rpm probe goes to one of the brushless motor cables. Alternatively (when one does not want to solder) I ordered one of tho...

I take some effort in balancing.

First the spinner without the blades and when I think, the spinner is OK, blades on and balancing the unit.

No idea, how to fit magnetos ...

Some better pics of that modified IR Sensor. https://imgur.com/BURPvaNl.png https://imgur.com/rN0zYu6l.png It is just an inverter, I put on it. https://imgur.com/VulkuWll.png The problem here was, this sensor needs a good reflection patch or area.

Hi João. In German forum I posted this thread about rpm sensors for bl-motors. http://www.rc-network.de/forum/showthread.php/674621-BL-Motor-Drehzahlmessung-mit-Arduino Both sensors work with oXs. Then I modified one of those https://imgur.com/6OoCbKVl.png with an inverter, so that also works now, b...

Isn't that a thing, we all are suffering from? Too many unfinished projects, projects I want to start with .....

It is the 'data-stream port'.

How to handle those 3 ports on the RX side is quite clear documented here

Did not want to offend you Jim.
But the main topic here is oXs.

See you in one of those Linux forums.

br KH

Jim, that is good news. :D But let me say, creating a launcher or starter, that are very basic things in Linux and in LM. Why not invest some $ in a book https://www.amazon.com.au/s?k=linux+mint&ref=nb_sb_noss_1 or even better Jim, join the LM forum https://forums.linuxmint.com/ It is a very act...

Yes. Logging Telemetry is ON.

I still cannot get it to install in terminal. Screenshots always help ;) YOU ARE NOT INSTALLING IN TERMINAL, you got to get it running. You stop here https://imgur.com/TGQYyg2l.png Why?????

Jim, did you - download the oXs zip package from here and unpack it? https://github.com/openXsensor/openXsensor You should see those folders https://imgur.com/CUOLT08l.png - install this package here ? Any error messages? sudo apt install python3-tk - then do, what you see in that pic here and the p...

First of all I would advice using a setup on the fly, using a breadboard and jumper wires. When you got this setup running, you can heat up a soldering iron. ;) With the BN-220, did you test it with a GPS software first? I use u-center from u-blox. And don't mess with the settings. Leave it with 960...

Hi Greg. Mstrens seems to be off at the moment, so I'll try to give an answer. All of your questions are answered in 'oXs_config_description.h'. This is a text file for documentation. You find it in the oXs package, you can download from here. https://github.com/openXsensor/openXsensor OK, I underst...

Before trying to get a oXs sketch on the nano, maybe you should try to get the basics with Arduino and the IDE.

Please try DATA - EXAMPLES - BASICS and use BLINK.

Here you find some YT videos

What a fuss.

Just run it in your preferred LM.

This is LM 19.3.


Do a in terminal to install the missing thinker package and then run the Configurator.

Arduino 1.8.10, oXs 8.2.13.

No errors with those two config files here ...

Thierry, you can now flash a simple hex file wit the USBasp onto an Arduino. Whether it is an Uno, a Nano or a Mega. That was the goal of this thread here. Flashing and preparing openTX on a Arduino Mega is quite another thing. The description is here for doing so ... https://github.com/opentx/opent...

So : direct flashing with Arduino IDE (and ArduinoISP) killed the UNO's bootloader. But why do you say that I can't use the UNO any more with Arduino IDE ? I can still load a program in it. Please read this here https://arduino.stackexchange.com/questions/49357/ino-hex-vs-ino-with-bootloader-hex Th...

'oXs_config_description.h' reads

Note : for the HUB protocol, only one oXs may be connected to the receiver (other sensors are not allowed).

It does not say

... only one oXs with only one sensor ...

So, get your Uno, the Arduino IDE and the USB cable. Modify the Arduino IDE settings 1.JPG for add. information while uploading the code. Now compile and upload 'blink' to the Uno. You'll have the add. info now. 2.JPG 3.JPG There is your blink hex file. Go to that folder on your WIN 10 and copy that...
