can u update code? ledcSetup and ledcAttachPin are no longer used so the code gives an error.

wowo

Very Very Cool Excellent work…….! I can hear your clock in the background ….🎶❤️🎶 I have 4 Old German ( wall clocks ) Weight Driven Chimers 🕰️ That a doctor friend of mine gave me years ago…. They were all four completely in pieces …🙄 I mean everything….! it would take me two or three days to decipher what pieces went with which Clock , before I could start attempting to repair and reassemble them… “ Even the wood clock cases, and the glass to each clock had fallen apart over the years….! 🤔 All Four are hanging in different rooms in my house…! And all keep perfect time……👍🏻 ( Did you restore and repair your clock or did you buy it working? )….👍🏻

Cool and nice job. Congratulations. I read that you are planning to do something similar and better. I am looking forward to it. It would be nice if it had object tracking features with the raspberry pi and camera. Are you thinking of creating a community by opening a Discord channel?

cool

Isn’t this impossible?

This is so cool

RESPECT, great job, thank you so much for sharing! My cube is workig perfect. Did somebody manage to ammend to code to get the cube turning?

Hi, I am a student, I have a project and a need your help. Can I get your email?

why 3 wheels and not 2? whats the advantage? I think 2 wheels would be enough. each for one axis

Hey if you tighten a rope with the standing corner and just hang this.. Is the cube still balence itself or just moves clockwise or anticlockwise.. Can you please check this

link to project?

is it possible to add an other gyro wheel for the other axis? a horizontal one?

Is it's weight limit proportional to the distance from center of the wheels, like if the reaction wheels were further out it could balance more weight or am I misunderstanding?

Hello, it is an impressive work, I would like to invite you to participate in a funded project here in Amazonas Peru, please could you provide me with your email?

Great Project- thank you. I am working through the build of your "better" version of the cube as a volunteer with a local charity - which includes a small 3D printer group. With regard to the schematic, we were wondering whether you had given any consideration to any extra safety features - such as a physical or automatic timeout switch between the battery and the PCB to prevent unforeseen damage to the circuitry. Do you have any advice on this possible danger? Many thanks

Still can't get beeper to work. Running version 2.3.3 of Arduino IDE. What library version for FastLED and Wire.h

Can you explain this part a bit? How do you determine the value? battVoltage((double)analogRead(VBAT) / 204); // value 204 must be selected by measuring battery voltage!

Hello, I have a question, could the Nidec 24h be used to replace the GM3506? If so, would gears be needed? due to torque. Nicee proyect

I just got mine working and its awesome, its still a bit jittery and my reaction wheels arent heavy enough for now but it works pretty well, awesome project!

Hi! Thank you so much for making this and posting the project! I'm trying to replicate this for a school project and we have a specific microcontroller that we need to use (mspm0g3507) and I don't have a bluetooth module. And I have a few questions I was wondering if you can maybe help answer... I know you mentioned in another video that the wires generate interference with the IMU and the I2C communication. Is there a way to do it without the bluetooth? Also, I was wondering if it would be ok to calibrate the accelerometer at the beginning of the program, similar to the gyroscope calibration, and just set calibrated to true after, or if there is a specific reason that tuning needs to be called at the beginning of the control loop each time? Also, I noticed that in tuning, an offset value was added accel_z to account for gravity. This makes sense for balancing on the vertex, since the IMU is positioned such that the z axis is aligned with gravity. But for the edge case, I imagine that a portion of the acceleration due to gravity would get projected onto the x-axis in the IMU frame, so should the offsets be a little bit different? Or does that not affect the measurement? Thanks again in advance!

is this cube able to walk?

Is it able to walk as the original?

I found myself in a bit of a time crunch and can’t get the Nidec servos in time, any recommendations for alternatives instead of the Nidec motors?

great project . i am builiding it for my research project in college I may try different control techniques I just have small question what the lego number for the rear wheel?

I have all the parts printed, the 3 motors arrived with the Arduino NANO, and I have the rest of the parts also. My problem is the wiring the motors! I purchased the exact same motors as you did, but in schema you show only 8 connections, but the motor has 12 wires! The wires 1+2 is +12V, wires 3+4 are ground - no problem here, BUT as per your schema it can't work, because the PWM is the last wire, Start/Stop is next to the last wire! Please, can you let me know where these wires should be connected at? The only part that is missing for me is the wiring. I started watching and following the other video, I didn't know that you are the original designer until just few minutes ago. ( Here is the other guys video: kzbin.info/www/bejne/rGTCZYOCqJmVqZI&ab_channel=MirkoPavleski ). He just copy your stuff and didn't give you credit for your work! Thank you in advance for your help.

Appreciate the added innovation in your design. Unfortunately I am getting the dreaded "angles are wrong!" during calibration. I am using the ESP32 build with Bluetooth. Some of the values I am getting are: X138.78, Y93.49 X140.23, Y94.16 X135.72, Y93.48 Any suggestions on how to resolve? Thank you.

Very cool project! 👌👌👌👌

seems fake

Excellent 👏👏👏❤❤

Whether can we use current FOS library version?? Or other version?? Could suggest me the FOS version sir?

Great project! Thank you! Merci! Only problem I had was that I bought the Nidec motors with 12 pins. No matter what I did, I could not get any encoder outputs, even after a week of messing around with my scope and power supplies. So I reordered the 8-pin motors and everything works. Haven't yet tried tuning. Thanks again...

❤❤

Hello, I'm a student interested in your project. Could you tell me how you connected the line? Did you connect it with the line in the Arduino kit?

I have an issue. I used the motor test script and everything is working. I am a bit confused with the calibrating though. When I send c+ I get a message to place the cube in vortex and then c-. All good. Then it says to place it in the edge. I do and send c-. After that is said: Edge OK and calibrating off. Shouldn't it ask be for the other edges as well? Do I have to do the c+ again from the beginning for the oher edges (Vertex and edge)? It never starts to balance though? Any pointers?

Also, Please what screws did you use. I realized you fitted a nut-like structure before inserting the screws. What are they?

is 3.7V 1000 mAh battery enought to drive the three 12V battery? Asking because I want to know.

Awesome project. I built your previous cube (worked great) but seem to be struggling on this one. I built two separate boards with the ESP32, LM7805 and BC588 (PNP) components that exhibit the same behavior. The motor test checks out okay but the for the cube balancing function it just beeps a steady tone and nothing happens. I checked the wiring connections for both boards several times. Any thoughts for troubleshooting (maybe it’s not setup correctly)?

How did u connected this?

Can I get the final working code???

where did you place the 3 MPU6050?

Can I get the circuit diagram for this sir?? It is not available in the source sir!

Making progress.Reinstalled Arduino IDE and all libraries and now get this when i verify: C:\Users\Mark\Desktop\esp32_cube_enc\esp32_cube_enc.ino: In function 'void setup()': C:\Users\Mark\Desktop\esp32_cube_enc\esp32_cube_enc.ino:55:3: error: 'ledcSetup' was not declared in this scope 55 | ledcSetup(PWM1_CH, BASE_FREQ, TIMER_BIT); | ^~~~~~~~~ C:\Users\Mark\Desktop\esp32_cube_enc\esp32_cube_enc.ino:56:3: error: 'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'? 56 | ledcAttachPin(PWM1, PWM1_CH); | ^~~~~~~~~~~~~ | ledcAttach exit status 1 Compilation error: 'ledcSetup' was not declared in this scope

Can u share which control logic did u use for balancing? PID?LQR or ML?

Nice work, excited

Hey can I get your email id

esp32?

How are you controlling the wheel torque? Is it closed loop velocity control or are you using current sensing. I am also using simple foc mini and same motors but my motors lift arround 100g only 😭

All your projects are wonderful. I have recreated several and they work flawlessly. You deserve many many more subs and I hope you get them in the near future. I congratulate you

Github??
