  • The second part of hacking a hoverboard motherboard, in this video i show you which wires to connect to what to make the motors move how you want,
    I cant put the code here so i will put it in a comment for you
    make sure you also get the Adafruit_MCP4725 and WIRE libraries or it wont work, feel free to ask questions in the comments

      ​@@A-tech Hello master!
      I looked at two parts of your video yesterday, and today I redone the gyroscooter with the firmware presented.
      As a result, it sometimes does not work stably with potentiometers, and as already noted, the use of DAC is required.
      I will also note a slow and insecure reverse. But he definitely is:)
      If you 're a firmware author for stm32, I have a question:
      Is there any firmware for implementation of the three H-bridge for brushed dc motor throught one hoverboard mainboard?
      I 'll follow the project closely!
      Certainly a great job has been done!

    Simple alternative with esp32 using esp32's own dac, without using mcp4725, pins in esp32 -> 25 and 26.
    CODE:
    #include
    #define DAC1 25
    #define DAC2 26

    void setup() {
    Serial.begin(115200);

    }

    void loop() { // Generate a Sine wave
    int Value = 130; //255= 3.3V 128=1.65V
    this value change to speed
    int Value2 = 150; //255= 3.3V 128=1.65V

    Hi, looking for an idea on what might be wrong, flashed the firmware from the link in the first video and all is good, no errors, but when I turn the board on with everything connected, it will slowly rotate the motor clockwise a couple times, stop and do the same counterclockwise, stop and the board turns off. All by itself. Pots have no effect whatsoever. It will do this with or without any pots connected to input wires. Im using the 3.3v pin for them. I flashed the board again, no change, everything was done to the letter from the first vid.
    Halp?

Anyways, I want to build a go kart with an old overboard thus I don't need the steer on the rear wheels,if I just leave the steer wires unplugged will the motors just steer in one direction or will they have equal speed(remaining locked in "forward mode with no steering")?

      hi, if you dont need steering i recommend the 'bobby car' version of the firmware, this makes the wheels go the same speed and has 2 throttles, one for brakes and one for speed, it also has different running modes, so you can have a fast mode which is about 20mph, on my video where i convert a mobility scooter into a go kart this uses the bobby car firmware, hope this helps, and thanks!

    Hi, nice video. I have a few questions:
    1. How can I set it for reverse? like for go-cart. In your video the steering pot seems only control either one wheel and turn into a different speed and direction. What I want is actually simple, I want to steer it forward with the same speed, and I can also drive it reverse (with a switch or else). Can you tell me how can I do that?
    2. Does the battery charging feature still work?
    3. How fast the maximum speed can we set in the code?
    Thanks before.

    • @A-tech
      @A-tech  3 года назад +2

      hi, ok there are 2 pots, one does speed difference, the other does speed for both, so for reverse you just turn the speed one down further than when its stopped and it will go backwards and bleep, for example the 1024 pot value would be something like 0-300 = reverse - stop, 300 - 1024 = stop - full speed, do for your DAC if you are using one you need to split it like that if you are controlling forwards and reverse with 2 buttons / sticks.
      Apparently the battery charger does still work, however i am yet to test it.
      Max speed depends on what firmware you are using and if you change stuff in it, the fastest one i have tested myself is the bobbycar version, it has a speed setting you can set when starting up, i think with a 12s battery it can get upto 30mph, its a feature called field weakening, there is more info on this online if you google it, i just set it in the firmware to run off a 10s battery and its fast enough, maby 20mph.
      There is a guy who hosts an online firmware compiler that i have used a few times, you can edit the code online, compile it and download the .hex file to upload to the motherboard, here is his channel: ruclips.net/channel/UCLUfNuoSML-vkLYiO0vBUHQ,
      hope this helps!
