There was this one intersection that i noticed this at. everything was fine but my remote was vibrating; like it was reconnecting. Happened a few times at this one intersection, not really anywhere else. On my 100d lonestar
Until these guys make motor controllers that can move my fat ass up a hill, not really a viable option.
Also there were VESC based ESC (stormcore, too) that didn’t suffer this issue, so your response seems a bit kneejerk.
We’re here to discuss why this could happen, not make unproven proclamations based on hardware that doesn’t exist in this market yet. In fact, we don’t have enough data to make any claim at the moment, this issue could very well impact other ESCs.
We were stopped at a red light. Light turned green, everyone takes off except 5 of us who all go “WOOOOOAAAAAHH! WTF?”
I looked at my maytech split trigger remote and it still showed solid connection but my board would only accelerate a foot or two before full braking randomly. Pushed the board out of the intersection and it was back to normal.
The extra weird part is that it happened the next night at the race track as well. I doubt there were any induction plates in the play ground. Right when the goofing was over and we were about to head out, I actually saw my board shut off (stormcore 60d+ led button turned off). Board timeout is set much higher than the break I took riding so it shouldn’t have auto timed out. I was literally riding it a minute before it happened. The second I touched the throttle, the esc “woke up” (led button came back on).
Board was 100% normal the rest of the event aside from these 2 incidents
Like @rusins, my stormie is flipped upside down with a heat sink on it (top of the box)
Insert random long rant about why EMC testing and radiation immunity is so important in safety critical applications. I know 0 distributors of VESC based hardware and addons that can show any data or testing. Which in the rest of the electronic consumer market is mandatory to even sell shit
Arguement before has been that its too expensive and volumes are simply too low or that its strictly hobby use and should be viewed as such. Stopping in an intersection in traffic kind of forces us to start paying attention to this tho.
So for now. Ride in traffic at your own risk. None of the hardware in your board is certified from any safty regulations to work in your benefit.
Perhaps the discussion can start here if we can gather data on these incidents in a reproducible manner?
This was definitely a shocking thing to see- there were probably 30 of us and we watched the folks on top of these sensors all have issues simultaneously- so from an empirical standpoint it sure looks related.
this is me every day, and I worry about this kind of stuff a lot
I think something similar happened to me with my TB6s a while ago.
Atleast IIRC they were TB6s. I was at a light and I stepped off my board to go and click the pedestrian cross button…after returning to my board I wanted to inch it forward just a bit before I got on it…and for some reason instead of inching forward it SHOT at full speed into traffic and got ran over and I needed a new deck after.
Remote was a VX1 connected via UART and I was using a flipsky antispark. Nothing like this has ever happened to me before that or since. I wonder if it was just an isolated incident of a VX1 remote flipping out or if these magnetic fields had something to do with it.
It’s also worth mentioning that there was an instance of this glitch at CarvePDX that occured when we were traveling across an overpass/bridge. We were in a car lane, all of us were moving the whole time, no one stopped until the glitch started happening. It seemed to occur right at highest point of the overpass.
All the same people were affected, all as soon as they passed over this one spot, approximately here:
Myself and @Boardnamics experienced non responsive throttle at the same place @jack.luis was the first to notice issues. I could full throttle my puck and it did nothing. It was an intermittent problem. Sometimes responding, sometimes not.
