I dont know if you are still answering questions here but: Hall effect sensors on the motors dont have a good resolution so I want to use a seperate hall effect encoder (like AS5600). Do I need to connect it to the mainboard or can I connect it to the arduino and modify the code?

Great series of tutorials, I followed this one but I am not able to put the board in auto calibration after pressing on switch for 5 seconds. not sure what I missed

thanks for this great tutorial, i have flashed numurous hoverboards by now, uart and pwm works fine. But i cannot get ADC to work. I flash the ADC variant but and wire up 10k pots to short cable. but there is no movement, just changing buzzing sound when turning the pots. then if i flash PWM firmware again it works as it should. i dont know what to do, got any tips? regards!

can i control the motor at different speed using this

What motor type are you using? Using gear reducer?

i did the same instruction and modify the code on config.h with the same changes just to connect the arduino uno to UART3 in the hoverboard , upload the code to arduino , bu the motors didn't moved , it didn't give me any beeps , any help ??

you use ROS1 or ROS2 ?

what does the strength value represent? is it like confidence or error?

😂

Just my kind of tinkering! Great hack to use the onboard motor driving array and skip the notorious motor shield and its plethora of issues! I am looking forward to trying this with my Roboquad that I have been sheepish to give a new brain to. Thanks so much for sharing your tips and knowledge. Buying you a couple of coffees as you saved me a week of banging my head against the wall lol.

Hey, I was able to flash the board, and when plugged in it does the on chime but I am not getting any response from the communication nor the serial error. When I unplug the Hal sensors its does give me an error for that but for some reason usart does not work. Anything to point me in the right direction? Thanks!

came here looking for help with WebUSB of all things, apparently that needs dhe creation of udev rules, too. really informative, thank you!

Should use a system like Ardupilot with Mission planner software suite for stuff like this. Very well fleshed out system

I want to roboting course sir.

can you please tell ..... i have been facing a problem from the map_updates my lidars are not updating simultaneously lase_scan is working but there is no updation in rviz2

What happens if I try to flash without the battery?

Thank you so much!! You safed my bachelors thesis!! :D

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

Can you use the controllers on the original board but not with the hacked uC but with an arduino board?

Does any knows how to make the motor start softer?

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 😅

Thanks so much, now i understood!

Thank you! Brilliant explanation!

I am so excited to find a video that explains how to use a normal joystick to control a rather inexpensive controller for wheelchairs. I love Fixing old Wheelchairs and getting them to people that can't afford one. I hope it turns out to be predictable.

I don't know how many people have told you this but you're very good at explaining these instructions. You're very succinct and it makes it very easy to follow what you're saying.

I want to reach you, can I know your e-mail address?

You can use the rosdep command install all the missing dependencies as long as your package.xml lists them all.

Man !!! This is amazing !

Thanks! I found some for 99 cents! This will be fun.

Hello , please can you put the link of the firmware complied for control using USART3

Thank you - great tutorial. I have a question: I Build an ADC-controlled electric scooter. If I want to control both motors at the same time, I only need to use one potentiometer on first input. And for the second input, solder GND->5k->ADC<-5k<-3V3? My scooter is at the frame welding but i wont to lern as much as possible about the controll.

When is the next video? You were doing great.

Amazing work, I followed your tutorial and perfectly work for me; I see you added battery state, I'would like to make a node that read your battery topic and publish to original ros sensor_msgs/BatteryState Message; Can you help me?

Gay

Thanks for your videos .

Thank you for your help! Can anyone help me with a question? In a scenario where I have two models for the same type of device, only one of them will always be used, never both together. Can I create two lines by configuring the same Symlink?

Thanks so much, now i understood! Great!

It help me a lot. thank you :)

😂😂 Worth buying

Are you actually measuring the RPM, or did you just empirically discover that a certain motor voltage results in successful reads?

Hey there. @6:22 Which software/editor did you use to do the git clone thing?

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! :-)

Any recommendations for doing this without using the hoverboard PCB, some sort of off the shelf driver I can buy?

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.

Very useful tutorials! Do you have any way to work the motors with a potentiometer and direction change option? Thanks!

I think this tutorial is bringing such a great opportunity for a lot of people to get into robotics cheap and not to hard to start, with. This could make the robotics community grow fast. Thanks for sharing and I hope to find you on LinkedIn

is it possible to replace hoverboard motherboard with arduino or raspberry pi?

⭐⭐⭐⭐ Thanks!
