Wow, it responds really quick! Nice job and thanks for sharing your code on github, I'm sure I can learn from you. I'm also currently designing my own vario in order to learn a thing or two about microcontrollers and also C/C++ (and also to help me pass the time until I can go paragliding again :)). One question though: Did you 3D print your case or did you buy it? It's really nice.
You're welcome ! Don't hesitate If you have questions. More feedback I have more I can improve the code reliability. No I don't have a 3D printed. I bought the case first and I have designed the variometer to fit it's size. On my GitHub page you have my email if you want to contact me for some infos.

Salut. Pour celui-ci j'ai utilisé un 3.3V. J'ai donc pris un pro mini 3.3V. Le désavantage c'est qu'il faut un cable spécial pour charger le programme dedans. Mais j'ai vu que le concurent (avec ses circuit imprimés rouge) faisait un modèle presque équivalent avec le ATmega32U4 et qui permet donc de garder un cable usb classique. Il n'y a pas malheureusement de micro 3.3v. Et vu que tout fonctionne en 3.3V c'est dommage de mettre un microcontroller en 5V.
Hi ! Actually it measure : -> climb rate -> altitude -> ground speed (with GPS) -> glide ratio -> flight duration It will measure : -> compas -> wind speed and direction Dont hesitate to contact me if you need help.
Hi Prunk Dump, you made the best and the most precise Arduino Vario. Thank you so much for sharing your idea. But I have one small problem with my setup. I have: Arduino Uno, MS5611, LCD 5110, Bluetooth HC-05, Speaker. So I only defined in a sketch variometer.ino: HAVE_SPEAKER, HAVE_SCREEN, HAVE_BLUETOOTH. Bluetooth wiring: Board Pin 0(RX) to BT TX and Board Pin 1(TX) to BT RX. I have succesfully uploaded it to my board, screen works perfectly. But I can't connect it with XCSoar android App. In app I setup Config->Devices B: LXNAV on Bluetooth HC-05, also baud rate: 9600, but I allways get Error or No data. In app Monitor I don't see any data. Do you have any ideas what shoul I do? Thanks
Hi ! At the time you write this message the LxNav sentences are not implemented without GPS. This is now corrected. Try with the latest version of the code. If you want to talk with me about this project, sign up on GitHub and use the email written on my profile. I'am happy you like my work !
Excellent, I've just uploaded your updated sketch to my board, connected via BT HC-05 with XCSoar - LXNAV protocol and tried in an elevator. It seems that precision is perfect (I calculated an average speed of elevator and compare with Vario value. It was the same +- 0,7-0,8 m/s up und down). I have just ordered MPU5060 for experiment with precision, but I think this setup it is already precise enough (or better) than some comercial varios on the market. Thank you very much, Prunk Dump !
I love it. Is it available preassembled with the yellow case? I know there's one here: www.rc-letmathe.de/DIY-Gleitschirm-Variometer-mit-GPS?languageid=2, but the case looks crappy in comparison. I'd much prefer yours.
if you move it to support ESP32 , then you can easily add bluetooth and could link it to this IOS software: flyskyhy.com It would make it the ultimate open source vario tool...
Thank you for sharing your knowledge with us.
Stay on the summit.
excellent work! thank you!
great work, thx 4 sharing

Legal, Gosto de projetos com arduino, estou pesquisando para montar um vário simples
Excellent! Je vais en fabriquer un aussi, merci! Par contre je trouve pas de source du boitier 🤔

Hi. Great project. One question: Does it measure only lift?
Hi !
Actually it measure :
-> climb rate
-> altitude
-> ground speed (with GPS)
-> glide ratio
-> flight duration
It will measure :
-> compas
-> wind speed and direction

@@prunkdump4890 Amazing
where to get a case for this project with printed pcb?

Where can I order the PCB manufacuring? The proyect is only in Kicad or mayby, you have it in Fritzing too? Thank you a lot
Hi. Just click on the "Get it" button on the PCB page. You have all files needed to order the PCB.
Regards.
@@prunkdump4890 I already got it, I have ordered to manufactured the PCB in China. Thank you a lot 🙏🏻

Sympa, petite question c'est un Arduino Nano ou Micro ?
I want to repeat the project! Can I ask a question about him?
Hello. Check the web page of the project in the description. You can find my email address.
I love it. Is it available preassembled with the yellow case? I know there's one here: www.rc-letmathe.de/DIY-Gleitschirm-Variometer-mit-GPS?languageid=2, but the case looks crappy in comparison. I'd much prefer yours.

You're right ! I bought some EPS32 board to try to port the code. Do you have some example projects communicating with flyskyhy with the ESP32 ?
no but he is willing to port to any published protocol
The PCB Plans where can i download?
