  Thanks a lot for the great tutorial! I have two questions: 1) Can I buy any hoverboard from Ebay/Amazon to run the alternative firmware? I.e. do all versions have more or less the same main board compatible to the available hacked firmware? 2) Does the hoverboard controller board support precise monitoring of the motor angle? I.e. are the hall sensors read as analog values to compute the exact position rather than just six 1/0 states per magetic cycle? And do the alternative firmewares, such as the FOC control provide these information? I am going to build a robot that should also be able to move rather slow but with very high precission, say in the rage of a few milimeters, to pic up very small objects and I wonder if the hoverboard is a good basis for my project.

  That's cool. Thank you so much. I have a question. How can one implement a hoverboard remote controller. This might be a joystick or just a normal remote controller 🤔.

  I am frankly impressed with what you do, I am a newbie to all this but I have reproduced your system and it works perfectly for me. I only have one problem, it doesn't have strength, if you put a person (me) on it it won't be able to move 80 kilos. Maybe there is something in code to increase strength. When I was a hoverboar I moved around without a problem. I hope you can help me. Thanks in advance

  In case someone is struggling with the serial communications with the Arduino / RPI, connect the ground of the hoverboard motherboard to the ground of the Arduino /rpi, otherwise you will become inconsistent communication and weird behaviour, is you are using a buck converter or sharing the same power from the motherboard you do not belong to the simple mortals I am talking to 😅

  Hi, thanks for this! Awesome stuff! Question, can I use one pot just to control throttle, for both motors? I am thinking about a scooter of some Kind! :-)

• 
  @PracticalRobotics Жыл бұрын

  For sure - that's how it works by default. One will pot will control speed of both motors and the other controls steering. Just leave the steering pot centered or even replace it with a fixed pot. However, I wonder if it might interfere with tight turns if speed mode is selected because turning requires different wheel speeds and speed mode will resist this. One of the other modes (go kart mode, or something) I think will not have that problem - read the descriptions in the docs or the firmware.

  Sure, you can find different BLDC motor drivers online, although most won't provide feedback to odometry and stuff. There are a couple that have ROS drivers for publishing odometry and stuff, but I've no experience with any of them.

  Hello! Great tutorial! Very useful and understandable. For my project I am trying to use a 7s, 29v battery. I change the settings (BAT_CALIB_REAL_VOLTAGE & BAT_CELLS) but I don't know what else to do to avoid automatic shutdown. I was trying to find BAT_CALIB_ADC for my set up, but I couldn't find a way to successfully connect through the right side serial cable to the computer to read the value of this Any suggestions are more than grateful! Thanks again.

• 
  @PracticalRobotics Жыл бұрын

  Hi, you need to adjust the values in config.h on lines 83-88. The 3 digit numbers are tenths of volts (390 = 39.0 volts, etc). Line 88 is set to shut down at 33.7 volts. Find safe and acceptable voltages for your battery and change those 3 digit values and you should be good to go.

•

  I'm not certain what you mean by direction change option? The wheels will reverse when the pot is moved past the center. I also think I saw a reverse direction parameter but it might be easier to reverse the potentiometer wires.

  @@PracticalRobotics Thanks a lot! I found the way for the rear drive as provided by the ADC mode and mid pots. However, I am looking for a solution for my own application and I am having a hard time. I want to have low rpm (about 100) and high torque. When I drop the rpm from "define N_MOT_MAX" the torque also decreases a lot. Is there any option to have low rpm and high torque?

• 
  @PracticalRobotics Жыл бұрын

  @@WhyNotCycles That's getting a bit out of my area of expertise, but these aren't known for having much in the way of low-end torque. You might try increasing the voltage - I think the original guys that did the hacking said they've applied up to 60v before things started burning. Maybe 48 or so would be useful without being dangerous... but I don't promise anything. I would usually look at gearing and a different motor if I really need more torque.

  Technically yes, but this would be exceedingly difficult and also require a lot of electronics that would cost more than the complete board. I definitely would not want to spend that much time to create something that can be purchased cheaper than the parts.

  Good day, I'd watched a lot of your videos regarding hoverboard firmware hacked and followed your video on how to install the firmware hack into the motherboard. But unfortunately the motor only runs forward and reverse and I couldn't turn it right and left. Since I'm not good in computer, is possible if you could help me program my hoverboard to run the way it should be. Just send you the motherboard and program the firmware. And let me know how much charge for your service. Sorry I'm not that good in computer. Thank you very much
