Re: build your very own Lebowski controller !

Interesting, thanks for the info. I think I just need to pickup a pickit 3...sadly, considering I bought the TL866 specifically for this (well, the idea was to use it for this, but have a universal programmer for future use)... guess I should have been more careful when checking if the chip was supp...

Re: build your very own Lebowski controller !

I can't seem to figure out a way... I went through pretty much every line of code in the git repo for the linux version. I also tried fiddling with some of the values in the device definition. Sadly, other than a few minor insights I found in the available code... most of the values don't have any i...

Re: build your very own Lebowski controller !

Obviously programming the PIC is my primary concern right now... I'm somewhat stuck right now... for all I know it is actually programmed, tho the program had an error during verify (which I suppose doesn't mean the PIC wasn't programmed correctly.. tho isn't the best sign). One other question... on...

Re: build your very own Lebowski controller !

So, did what I said above... made an entry for PIC12F617 by copying the PIC12F615 and editing the code_memory_size to '0x1000'.... and when trying to program, I get almost he same error... except (and to no surprise) instead of "incorrect file size 680 (needed 2048)"... I get "incorrect file size 68...

Re: build your very own Lebowski controller !

I'll see if I can figure that out... BUT I have a feeling I will still get the same error from the hex file... I'm guessing the hex file needs to be '0 padded' or something like that, to match the file size. I could be wrong, but my gut says it's something like that. EDIT: I found the file with the ...

Re: build your very own Lebowski controller !

So, I got the Power Supply portion of the original through hole board pretty much complete... BUT I still need to program the PIC12F617... I have a MiniPro TL866A universal programmer, which should be able to program the chip. But I have 2 issues. First off, the PIC12F617 is not listed in the GUI's ...

Re: Strange issue with e-scooter controller, and battery voltage

AS always, thank you for the advice/recommendations. Ha;f the problem is that I am doing the work on the battery and/or controller at my apartment.. while the rest of the scooter is at my friends place. You're probably right about there being an issue with one of the battery groups (or more) under l...

Re: Strange issue with e-scooter controller, and battery voltage

Amberwolf, again, thank you. So... I decided to just take apart the battery again, and inspect it... unless I somehow missed a group, and I don't think I did... it's actually pretty much perfectly balanced.... every group within .02 V of each other... practically all of them showed up as 4.173 V.

Thanks for the advice amberwolf (again, haha, very appreciated). I'm gonna replace the FETS I guess (might as well) and see what happens. I guess I should concentrate on the battery if this is not the issue.. it's by far the most likely things next to them. I have a 10s iCharger....so wouldn't be to...

Re: new cyclone 3000 w mid-drive kit?

Thanks... I calculated my controller's Rshunt a while back, and double checked it more recently. Assuming the method I used is valid, I should be good. I'll double check to see if what UI did matches what is recommended there... I used the method described here pretty much exactly https://www.youtub...

Re: Strange issue with e-scooter controller, and battery voltage

It's possibly it's the battery... I need to get an ammeter in there... but seeing how its not running a motor.. or really anything.... I didn't think it was dropping voltage due to load, was thinking it was more likely a short or something... but I could be wrong. At least I'm learning more as I go ...

Strange issue with e-scooter controller, and battery voltage

So, I;m trying to help a friend fix his 60V scooter. The battery had been drained and left that way for some time,... I took the battery from him, and brought the charge back up to about 60V and returned the battery. The scooter had been running fine before the battery died (months ago). He reported...

OK, so I got the basics working pretty damn well I believe. I took the Cycle Analyst out of the equation for the test ride... and HOLY SHIT.... this thing is a f*cking death trap. I could barely keep the front wheel on the ground... so much so that there was a number of occasions that I didn't even ...

Re: new cyclone 3000 w mid-drive kit?

Wow... I think I just got really lucky. After rotating my phase wires 2 times, I suddenly had the motor running in reverse, but seemingly with full power. The wiring for that was: Controller's Blue to Motor's Green, Controller's Green to Motor's Blue, and Controller's Yellow to Motor's Yellow/Orange...

Ok, looks like shit might still be messed up on my motor.

BUT it only does about 1-2 rotations, then it stops when I hit and hold the throttle. ...

BUT based on the sensor wires, and their connections on the main board.... I decided to switch the Green and Ye...

Re: new cyclone 3000 w mid-drive kit?

I finally got my clone all setup, with a cycle analyst v3 and a 20s battery. But, when I turn the bike on, and hit the throttle, the motor just grinds, and barely moves(pretty much just shakes a little). My first guess is that the phase wires are not connected in the right order (I replaced the conn...
