Vesc Conversion Status (Rose/Mika)

Lia

@loaffette Hope they get back with a fix. Probably something replaceable has blown if you know someone with a reflow iron and steady hands.

LOAFFETTE

@lia they just told me it's dead and needs to be sent back
I'll probably poke around inside and see if anything looks broken or busted

Lia

@loaffette Assuming the fuses did their job you should be fine.

Check continuity between the highlighted components. If one shows Open Loop then that needs replacing with another fuse.

Good luck!

LOAFFETTE

@lia I'll check
if that's the problem and the board powers on afterwards, then I'm golden

I did notice earlier that when i have the power button plugged in, there is that little pop, but still no power

LOAFFETTE

all of them seem fine, but BF on mine is a tad bit flakey

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.

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.

LOAFFETTE

@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
