I would be interested in one depending on the price and if you are willing to ship to Europe (Neherlands).
Thanks 
I made one and it works, but I’m having trouble trusting it to be reliable in high speed situations. Did you do anything to make sure it wouldnt fail on you? @goldenHusky
so in a nutshell, what parts do i need to build one? asking for a friend
@fafi.azucar I haven’t made one yet, but I am planning my parts list. What I have planned to make/buy so far is
- Accelerometer
- Arduino (mega I think)
- VESC
- Gokart wheel with hub motor
- Led lights for the front and back
- Batterypack
- Aluminium rails
- Pressure sensitive pads
- Wooden plates for both ends
- Griptape
- On/off button

Check the popular links at the top, there are quiet a few build descriptions in there. Those helped me a lot to start off this project.
@ Dblaron, i’m not able to send you a PM, but i’d love to join the group buy if that’s possible!
I also managed to find spare tyres for this type of wheel. https://www.peipeiscooter.com/dc-hub-motor.html?product_list_limit=30
What kind of voltage would do you guys prefer to use and why?
The hoverboard hack is brilliant, the self balancing hardware and software is all done and it even has a pair of escs , just add motor and done, well with a couple of hiccups, escs are rated for 6.5inch 350w hoverboard motor the inventer only got theoretical 700w motor by combining both motors and using both escs, These hoverboard mainboards are cheap what about overvolting them to 12s vs 10s and possibly upgrading fets to run the single aliexpress hub motor?? you would only use one of the escs and one of the gyro boards with no other modification any opinions?
ok just found some more info on the cheap hoverboard main boards they should handle up to 13s which will increase both speed and torque, so 20+ should be no problem best to upgrade fet heatsinks for extra insurance, standard fets should be ok but check ratings as they vary depending on what they can get their hands on! this is all with standard firmware (propriety) or another option is to use electric unicycle mainboard probably very similar but these are rated around 60v, not sure how the larger 14+inch wheel size will affect things though?
At first I was going to use a unicycle main board. The biggest problem was that the the board had to be mounted vertically like in the unicycle on the side of the wheel. Could not find a different firmware where the gyro axis would be swapped.
I ended up using a VESC 4.12 and an old Naze32 flight controller board from a quadcopter. Here is the link to Alex B’s code that I used. https://github.com/blezalex/WheelBoardMain. Still have some work tweaking the PID’s but I can ride the board for short trips.
good work, are you going to further develop the code? I threw out all my old naze32 boards!! all f4 now I am good with electronics hardware but my coding sucks, am interested though done a little with arduino using their IDE any advice where to start? eg what IDE to use and how do you compile and upload to the board?? written in some version of C I assume?
I’m also not good with coding. Learned enough to get my board working. Alex B helped me to get his code working on my Naze32 board. You have to use CoIDE, compile and flash his firmware.
If you want to use arduino+MPU6050 board check this https://github.com/schglmnn/VESC-OneWheel. I got this working also but I was not happy with it.

Working on my own one wheel atm, was trying a weekend build. Everything is done, just need the controller. Diddent have a gyro laying arround so trying to use a microbit, but dosent have my hopes up

why not try using a hoverboard esc mainboard, they are cheap and the firmware is good to go ? eg https://www.aliexpress.com/item/Universal-for-6-5-8-10-Inch-2-Wheels-Self-Balancing-Electric-Scooter-Parts-Hoverboard-Motherboard/32796726976.html?spm=2114.search0104.3.1.cf092d13h4Dosg&ws_ab_test=searchweb0_0,searchweb201602_4_10065_10068_10130_10547_319_317_10548_10696_10924_453_10084_454_10083_10618_10920_10921_10922_10307_537_536_10131_10132_10133_10059_10884_10887_100031_321_322_10103,searchweb201603_51,ppcSwitch_0&algo_expid=7ad6e412-a68c-4998-85d7-3bca2d02bb4a-0&algo_pvid=7ad6e412-a68c-4998-85d7-3bca2d02bb4a
Looks really nice i must say! What type of motor do u use, what voltage and how many Watt? And how many Cells are u using?
can u put up the parts u used? maybe the links too? it would be helpful😊
Im running it on 12s vesc6 with 20-30A It peaks on 1600w or so, and seem to really strong. I programed a microbit since i diddent have an gyro breakout laying arround, but the microbit wasent fast enuff and also did software imlement ppm. This made it unstable and lagg. This was supposed to be a weekend project, but im stuck with exams for now. Il make an propper build thread and post source code and parts in late desember. Im using 12s 3p from old laptop cells 18650.

Im working on building my own vesc6 that are really small. Il post a propper thread when im finished with them
