strong signal (damn, I was impressed by that, much better signal than the mini remote which it was really very good, I couln’t notice any signal drops, probably it uses a frequency that doesn’t clash with speed cameras or it’s just stronger, really nice job)
very compact (for guys with big hands like me it’s probably too compact, I have to operate the thumb throttle with the middle of my thumb)
simple but strange binding procedure, I’m not sure why but had to wait a bit (few minutes) before it could bind successfully but then it’s good
because it’s a thumb controller it’s less sensitive so I’ve reduced my motor max from 60A to 50A and motor min from -32A to -27A to be able to control better acceleration and braking
edit: new ride log, much smoother with the new settings
@rpasichnyk I think the magic number for making the overlay match the video is 0.952 - probably you can change the js that produces the video and set its speed?
I am setting the speed after importing it into the video editing software (premiere, fcx, imovie, shotcut, avidemux, kdenlive, openshot) at 95.2% and this time I think the sync is perfect trougought the video < 1 sec difference between the log and the video I think, I’ll test if it’s 0.952 for the next video as well - btw thank you for the zoom feature on the logs, very helpful
edit:
I had set 60A total (my battery is 10s4p li-ion with samsung 25r 's) and had a fuse of only 40A - fuses can blow at a bit lower or higher amps / time deltas if they’re not good fuses - I will take a 60A fuse in the future but for now I want to stay a bit lower than 60A, I don’t think I need 60A on a cruiser board lol
at what voltage are you running the carvon v2.5? also how much do you weigh? hills / crazy speeds or chill riding?
if I were you and had the possibility I would attempt changing to foc, the motor actually supports it if it’s not damaged (one of the two that I have has been slightly damaged [damn rock! :D] it doesn’t runs perfectly on foc, it stutters a bit at high amps but still runs more than fine for my usage)
I believe that if you monitor the vesc temp and currents via a bluetooth app like gpxlBen/@evoheyax - @rpasichnyk one or @Ackmaniac 's (which uses the least expensive bluetooth module) you can prevent the vesc from failing.
I guess that if you monitor values like input (batt) amps and vesc temp and make sure they stay on acceptable limits while you test-ride it … probably foc will work stable after that
Also follow jacob’s / vedder advice and put observer gain at 100 after the foc setup/detection, it works much better than the default (13.6 or something)
I am using @goaxle vesc. They went the same way as chaka when it comes to upgrading their vesc’s. I think most problems with FOC was with 12s setups. My battery is 10s4p.
how much do you weigh? any long / steep hills during your usual ride?
edit: Vlad and MasterCho seem to have no issues… maybe you can try it? my suggestion is make sure it starts with a gentle push and accelerating slightly - then test breaks lightly then test accelerating harder and breaking harder in steps - go easy with your first test ride don’t go on supersteep hills or at max speed straight away
I weight around 75kg. But I have a small backpack always with me. with some gear. not super heavy tho. …right now with BLDC when I get proper momentum I am riding some hills without any issue.
you’re light, I think that a single 2.5 @ 10s will be enough to drive you around, foc has less acceleration right when you start but when you’re over 10km/h you will get more torque than bldc I believe! also acceleration will be smooth than on bldc, but I guess you’ll get less top speed (which at least for me is totally fine)
top seed on flat should be the same for single and dual, on 10S I get 44km/h which are ~27mph with BLDC, on FOC my current max is 39kmh (~24mph) but I guess I can push it further
On this one I blew the fuse, duh, I had set 30A as my max input current per vesc because my battery can stand it but it was too much for my fuse (rated 40A) so I had to finish the ride/video there - I set 25A per vesc now and put a 50A fuse now
edit: the reported current in the log overlays is for 1 vesc only
it was just a dream ^^, but yes I’m a bit afraid of letting people I don’t know try my board in general because if they know how to ride a longboard and they run away, for sure I will not be able catch them probably a feature to implement on the vesc firmware or on a bluetooth connected app would be a timed or remote kill/switch that makes the board slow down and stop after a cerain time after activating such a mode or if you press a button on your phone… maybe it’s just me being too paranoid lol
@makevoid@naf just letting you guys know, I run a single 2.5 on 12s2p on foc, and I usually hit 32-34 mph, max I hit was 38 (slight downhill). I have yet to change observer gain, does, what exactly does it change?
