The Onewheel GTXS (Half scale GTS)
-
I couldn't just stop with the XS. Literally started planning after getting back from OpenSauce. Especially since I want something that I can truly ride at least enough to prove it works and maybe something for next years OpenSauce.
Goals/improvements for this are to:
- Increase from a 4s1p to 6s1p pack with more current available.
- Possibly get CANbus back to a flashed chip that'll piggyback the BMS.
- Use a larger motor.
- Custom VESC.
- Get the float package to work fully with it.
- Use the recurve rails instead of stock for extra rizz.
- Metal controller housing.
- Injection moulded or cast plastics.
- Maybe a custom full pad sensor.
Custom VESC sounds hard...
Cheap-FOCer 2 is open source so I downloaded, converted, modified and redid some bits to make a tiny GTS controller.
That's an XT30 btw, it's half scale. 85mm across and 64mm long. FM branding on there because it's a replica. I'm getting as many details and hiding easter eggs... like the mosfets being the ones from the Pint.The original project was done in KiCAD. I'm an EasyEDA girl because I use JLCPCB and the library integration is just superior. Sorry (not sorry). Kinda had to redo the schematic since EasyEDA sucks at converting the files. Spend 3 days straight making that PCB after ironing out the schematic but it speaks for itself. Added USB C, Bluetooth natively and some lights that I hope to get the float package to handle.
Also got myself some test models for fitment and started tearing down a 250w esk8 motor. 100 more watts than what I got in the XS.
Basically I'm waiting to get some of the PCBs made so I can test if my VESC works. If it does I can fab the daughterboard for the motor/footpad connector and add that on too.

lol omg i would pay handsomely for a working pocket onewheel!
XR's got what plants crave!

I know that this is all research for Lia's home board . . . I'd like one for each floor of my house, with the power of at least a GT, max speed of maybe 5 to 10 mph, and all cushy so it won't damage walls or furniture. :D

@NotSure I'd love to sell these or partner with FM to bring these to market. Though one thing I realised recently is it'd be a huge liability issue especially considering everyone's gonna try putting pets and their kids on these 😬
@OneDanGTS You'd be amazed how much damage these things still manage. Even the XS was a little terror. In testing it dented my wall, gashed my thigh and knocked over my GT nearly cracking a tile 😅 This little monster is surely gonna cause chaos. Might need to bide by my own warnings and put a leash on it.
So still trying to pry the tire off the motor. It is THE WORST. Whoever thought casting the tire straight to the motor is actually just evil.
Decided to take the whole thing apart while I was at it to see if I could maybe do a custom hub casing since I'm getting the hub plates cnc'd anyway. Not sure if I will still but being this early in prototyping I might as well do a lil investigation to see if it's worth the effort and additional cost.
In the meantime I've done a first prototype of the daughterboard for the connectors. I underestimated how tight this was gonna be! I was going to stack 1x2 2.54mm pitch headers around an MT30 for the motor port but upon modelling it I realised it'd be too big for the housing to handle at this scale.
To get around it I've had to separate the hall connector and will make an ovular connector for the motor rather than a circular one.

They would if they know what's good for 'em!
