CG scale for F3X gliders
It is mentioned that 2 kg and 3kg sensor are supported but the 3D printed parts only support 3kg sensors (drill holes for 2kg and 3kg sensors do not match),
Hello
First thanks for this work, its very nice.
I would like to make a suggestion, maybe you can make the wing supports a bit wider... i printed one set and for example are too narrow for f5j gliders, like xplorer for example
Thanks!
Hi, Re your comment on the quality of some HX711 modules. I can see several on AliExpress, but cant see how to pick the units with 10uf capacitors. Can you link me to a good unit please?
Hello olkal
Thank you for this project. Please note, I am a beginner.
My question is to do with the wiring of the lcd, specifically I2C, Circuit_CG_scale_r3.fzz refers. you have a wire running from 16 on the arduino to the positive and negative battery terminals. Please could you tell me what this is for and if it is necessary for connecting to an I2C LED.
Thank you
Mark
Good morning,
I'm having difficulty finding the YZC-133 3kg load cell in Argentina. However, I have found 2kg load cells available.
My question is: Can I use two 2kg load cells instead of one 3kg load cell? If so, would I need to make any modifications to the code?
Thank you for your attention and I look forward to your response.
Best regards.
Hi Olav,
thanks for your great work on this project … I’m just ordering all the parts to print and build one or two of these beauties.
One thing i was wondering about is whether it would be possible to release the CAD Source-files? This would make it possible for me and other enthusiasts to adapt the scale to specific needs, especially regarding fuselage proportions, but also possibly making the construction sturdier for heavier uses.
Even if the CAD you used to construct these does not allow great interchangeability, some lossy but portable format (STEP? Is there something better out there?) would help a lot.
I think this would greatly help many users, and widen the adoption of this great “thing” even more.
Thanks for your work, I’m looking forward to building …
Best,
-Dario
hey guys,
can anyone design and release a .stl file of a bigger support for example like already existing, ....ky design, with a width of 86 mm and height of 79mm?
thanks and br,

I've built this according to assembly instructions but get no output on the LCD and get no reading of the load cells. The display works with the examples in the LiquidCrystial_I2C library and I entered the correct I2C address in the config.h file. But all I get is a row of dark rectangles on the first line of the display.
Also, when I run the sketch and open the Arduino IDE serial monitor I can successfully run the menu, but get no valid data from the load cells. Once again, running the examples from the HX711_ADC-master library gives good data, so the connections are correct.
Any suggestions? Thanks in advance!
Hi,
I have now built 3 scales after your model. Wow, everything works so smoothly ^_^. Thanks a bunch!
To ease building, I quickly switched to using these ready-made LCDs which come with a I²C-Port-Expander piggybacked. Much less soldering, no custom circuit, and no 2nd Arduino to program!
I added optional support for this „third“ display-type (after serial and serial-to-arduino), and would like to PR this. However, I’d like to add documentation and wiring information for future users too.
So, what do you say about switching the documentation to an editable format, like MarkDown? Also, could you maybe share the source-fritzing for your wiring-schematic? That way my wiring-schematic would look the same as yours, which is nicer for users.
Let me know what you think … ^_^.
Thanks

Thanks for a great project with some really nice and comprehensive documentation.
A couple of points:
Calibration is described as needing to be written to EEPROM, but it seems unclear exactly how and why. The values look to be used when the code is run and nothing seems to be necessary to un- and re-comment. I'm guessing the code has changed but the instructions didn't?
I'm quite certain that there's a bug in the check for the output value to I2C.
#ifdef I2CDISP if (output != 0) Serial.println("You have I2CDISP defined, but output is not 2. Are you sure thats right?");
But surely, the message should be displayed on serial if the value is different from 2 rather than different from 0?
Hello, can you share F5J version .stp files?
