Vesc Conversion Status (Rose/Mika)

Update
No bueno on that old controller, it's deader than a doorknob. I held on to it for measurment references and to recycle the XT-60 on it since I was out of those. Spent the rest of my time experimenting with COB LED strips
They seemed bright and worked well. The idea is to utilize the 12V (1A assumed) power output from the Ubox 100v. Split it so two of the wires carrying the voltage goes through a boost converter to bump 12 to 24v for the LEDs. At the same time, run the other two wires to a buck converter to drop it to 5V for the Wemos D1 which will use WLED. That will let me control the LED's colors and brightness.
It worked on the bench, so I buttoned the rest of the board up enough so it could be taken back to college
Re-terminated the wires on the motor just so it was cleaner, and covered it in heat shrink. I might end up peeling that heat shrink off and re-doing the wiring again because it was a pain to fit through the cable gland, and I think I could make it look cleaner.
So, remember how I've been having trouble with the screw threads on my rails?
I took the Easy Access box STEP and pulled it into CAD. I added these little legs that extend out enough to cover the back screw holes for the bumpers. There's a hole for 10-32 heated inserts to go in, where it should give me new threads. I had to sand it down a bit, but I got it to fit and it works well!
After I moved in and my new controller arrived, I got right to work placing in the new controller. I had some fun with my iPad automatically updating to Vesc Tool 6.05 which made connecting to the board impossible via iPad (
stupid thing) so I did it on my Galaxy Fold, which hadn't updated the app.
After too much work, I got it all put together! However, the LED bar on thr front started to flicker like crazy. I checked the wiring, checked for any shorts via continuity across the wires and even swapped out the Wemos D1. I even ran the LEDs with only the power and ground connected, and it still flickered and changed colors.
I was going to replace the LED strip but I can't find the rest of mine, and I don't feel like ordering new ones
The board works now, and is working great! I'm hoping to waterproof it soon before it rains. I printed the controller box out of PETG with a 5 layer thick wall, so hopefully that should keep it sealed.
113 volts?! I could lick that!

The board compared against my mom's pint. I'm hoping to soon replace the tire after 500 miles and to get her an enduro. She can ride the board and balance on it, but she goes very slow and her feet and ankles are shaking on the round tire of the pint.
That's a later project though

Nooooooooo 😠Anyone nearby who's handy with a reflow station that could take a look?

Are there filter caps on the LED strips. It's possible there's enough noise from the run length to cause it. -
@lia Nope, not yet on the reflow station
Everyone I knew who had one left for greener pastures (They're all smarter and crazier than me and got scholarships to better colleges)The LEDs flickering might have been a good thing too. It made me realize that those strips weren't bright enough for what I wanted (even though they were 24V)
Though I may end up putting my old stock XR headlights back in for now -
New update:
The motor has started to vibrate whenever I apply breaking. It's like haptic buzz vibrating. Updated firmware, recalibrated the motor and went through motor crunch troubleshooting.What fixed it was unplugging the Hall sensor plug in my veac and plugging it back it.
A little confused now
-
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!

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.113 volts?! I could lick that!
-
@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 -
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 -
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.![IMG_9512[1].JPG](/assets/uploads/files/1739293261386-img_9512-1-resized.jpg)

@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!
