Vesc Conversion Status (Rose/Mika)

[LOAFFETTE]

I'm ALIVE!

So, found out the reason why my LEDs were freaking out was due to EMF from the phase wires. Will spend some time this weekend to cut up a spare USB cable to shield the headlight cable.

Also, I am considering seeing if I can look at waterproofing my board completely
I have a feeling the rain this year is going to be insane
I also built a trunk thing for the onewheel

I was gifted actual power tools and so I used them!

[LOAFFETTE]

hey, you wanna hear an idea so stupid it rolls around to being absolutely genius!?
No?

too bad

I went to Houston this past week. It was fun, and I got to ride a really cool bike path! However, I forgot my charger in Dallas.
While I was sitting in the park, waiting for my dad to pick me up from my ride, I was looking down at my phone powerbank. It has PD that could easily power a steam deck or a macbook. I then looked at my board.

Then the part of my brain that everyone wishes would stop working turned on, and I had a really cursed idea.
What if you could charge a onewheel off of USB-C PD? The idea is simple: You have a Type-C port that automatically demands 20V/the highest PD that the charger can support. You then had a DC converter that steps 20V (or whatever voltage you can pull out of your macbook/ipad charger) and step it up to say.... 75V?
Have an XT-30 plug that you can plugin GX-16, XLR, XT-30/60/90, Pint/GT, or whatever cursed plug your insanity-tinted glasses head likes to use!

Would this be useful? Probably! It's going to be ~$60 to build in parts, not counting filament cost.
I'm waiting on this for now as I have a couple projects I need to finish up.

@loaffette Nick and I thought about something like this but I've never seen PD outlets in the wild (at least in the UK). Especially any spec'd for high wattage.

I know the spec can go to 240W which is insane but other than a few premium battery banks that might give you 5-10% charge after losses it's not something you'd see a lot to make work in a pinch.

bought a Superflux HS Mk2

Will drop it in soon
Also working on a couple things rn, will keep ya'll posted once I finish it

[LOAFFETTE]

Got the Superflux on, currently don't have a picture yet
Things to note about installing a superflux-

The thunder tire is literal landfill. Just throw out the tire, it's not worth it. I had my tire for about two days, went on a trail ride and the tire developed a flat. Swapped it out for my old Enduro and it was much better

The male connector has way too much meat on the connector. IT needs to be trimmed because making it fit within the rails is a hassle and a nightmare. They should cut it by about half an inch from the cable in terms of connector for better flexibility. I already know two trail riders local to me who have done this.

The superflux hs HAS SOME GAS
That thing flies like a bat out of hell
It's one hell of a motor, and it was worth every penny

[LOAFFETTE]

Here's a pic of the tire change. You can see how terrible the old motor was (the motor with the purple cable)
I'm not even going to sell the motor. It's got 6k miles, the cable is messed up and the bearings are the same ones from day one. I'm going to bring it to a lecture one day to take it apart for a lab then keep it as a trophy.

The current goal now is to waterproof the board, finish my headlight project and then to give the board a visual overhaul

@loaffette I use to carry a solar charger, a 36v hoverboard battery, charging adapters, in a camera bag for group rides.
The solar charger converts the 36v to any higher voltage up to 90 v all programable with memory for different boards.
I've gone to 24s, so I can't use this anymore.

[LOAFFETTE]

@lemur very interesting
I'll have to look into that option
I remember Wren for CD using a setup like that for his board

Hey just wanted to say Ive read pretty much the whole thread due to somehow finding this page when searching for DIY solutions to VESC issues. It was a fun journey to see everything you've done to build a really decent board!
Im riding a totally self built VESC board and I love it. Think ill upgrade to WTF rails soon and some decent sensors and footpads as im still using tiny spintend sensors and homemade footpads from plywood and griptape.
But I ride every day and I love it. Cheers for sharing your journey!
its a big learning curve.. lots to work out and its a real sense of achievement once you get things really dialed in theres nothing like building your own board from scratch!

[LOAFFETTE]

Alright, I think ya'll need an update for the board.

As of writing this, I have switched to a metal controller box based off of the Pubbox design, which is amazing (outside of the thirty lid screws), went to the ennoid MK8, then back to the old ubox 100v. Added LEDs, 3d printed footpad with the first five milimeters being near-solid PETG with the rest being TPU and the stoked stock v4 sensor, and then the thundercat with WTF BTG rails.

The board is currently in a weird state of un-death. I made some idiotic choices and browned out my MK8 enough times to do what I'd assume permanent damage to it, along with finding that somehow an SMD capacitor came off of the MK8 (wild). Spent the better part of a couple days then switching back to the ubox, only to find that the NRF data and ADC2 being dead. Greeaat

For the past month, I've been fighting the board to keep it running. It started with adding LEDs running directly off of the MK8. Bad choice, as that would cause the board to brown-out mid ride, and I'd get some very nice road-rash. Took out the LEDs, and it seemed like the problem went away, for two weeks. About two weeks ago, I switched to the metal controller box. The first ride with the board, I did a curb nudge after about twenty minutes of riding, and the board stated to make crunching noises intermittently, with no real pattern. Re-calibrating the motor caused this issue to go away, but after about twenty or so minutes later, the crunch came back. Double-checked settings, uploaded new firmware, reflashed the MK8, nothing fixed it.

I spent a solid week chasing everything that could possibly be the issue.

I can't tell you how many times I considered either tossing the board, parting it out or just straight up taking my mom's pint and doing unholy crap to that.

I think I've dialed it down.

VESC Tool has a command in the terminal called hall_analyze, which lets you.. analyze the halls? Idk, it's VESC Tool. It's both the best and worst thing to exist. It's supposed to be used to troubleshoot your motor halls. You're supposed to get nice, clean square-wave output, with nothing weird or fishy about it.

Above is my hall sensor. It's not clean, and it looks a little suspect. Those strange, sharp dips could be either Vesc tool absolutely crapping its brains out, my halls in the motor screwing up, or a mix of both. I already tried this with both my MK8 and Ubox, got similar results on both. Could be the motor, could be VESC tool. I hate this damn hobby-

So, where are we at right now?

Well, I have four new hall sensors coming in, because one of the hall sensors DEFINITELY has damage to them, and it'd probably be a good idea. I've ordered a replacement MK8 with 120V MOSFETTS, and I'm currently trying not to go insane.

Also, this is all happening in between finishing up my last couple weeks at work, packing up for my transfer to Texas State, preparing for an event I'm going to called San Japan (Going with a group of friends against my willpleasesendhelp-) and having to juggle adulting stuff.

Hopefully I figure this out in time.

I'll keep ya'll updated.
I have no idea how ya'll do this crap

[LOAFFETTE]

One more thing-

GX-16 can be used in place of the switchcraft connector, it fits if the screw part of the connector is oval-shaped.

And I somehow managed to gaslight my Ubox 100v into making it think pitch was roll, vice-versa. I assume that I've either done something I shouldn't have, or I've messed up on IMU calibration.

Once I get this whole thing figured out, I'll post a more detailed write-up on my board as it currently stands.

@loaffette Hope you get the the Ubox set up, I had a sutdown problem with my MK8 150 with a shutdown while riding. Apparently, the long press firmware does not have a default auto shutdown while idle, and if you set a shutdown time on the LP firmware, it may shutdown while riding when the shutdown time expires, although it's supposed to reset to no shutdown time after rebooting.
I switched to the short press firmware just to be safe and had zero problems since and running any lights on the MK8 is risky, I removed light on my MK8.
