@birty This is a very interesting project, if you need help, you can bring it up


Cool, but seems my project is already was completed.
ATV Dashboard on Khadas SBC

I wrote about it here - Поддержка русскоязычных пользователей - #391 by OldNavi

It was build on Khadas VIm3L SBC + Atmega328 controller + with custom Android Pie (new fast I2C service in android). And really huge custom android application with navigation, music player, K-line communication with ECU with ECU analysis and sensors, and special code which allows several ATVs to see itself on a map using bluetooth BLE advertising broadcact messages. And of course everything was 3D designed and printed.

So does completed projects qualify for competition ?


Привет! Конечно можно !Почитайте условия ,там всё расписано .
Удачи тебе :wink::+1:

@OldNavi Of course, this is a very successful work, you can sign up and use your work directly.


Thanks for that, I’ve registered for participation with this project. However I’m going to start a new one DYI project in different area (Audio DSP processing). Can I have 2 projects for participation ?

@OldNavi Of course, if you have two different DIY projects, you can register for both, but you need to fill in two registration links because your project is different

Hello All,…

@Frank from Khadas Team.

I think Khadas’ 1st Community Competition regulation need an update :wink:

Here, “The judges of this competition will evaluate the following 5 aspects,” 5 should be replaced by 4.

Here, “3.1 The competition awards are set as follows” 3.1 should be replaced by 1.



@DerFu Thank you for pointing out the error in the documentation
