I second that, there is a possibility of heat shrink getting shrunk into non existence PS: I meant if using normal diodes

I think a properly tuned torque sensor based setup would not cause such a problem

Low speed & high load on the motor means phase current will be the maximum. Since hall & phase cables run close, there is a probability of the high phase current inducing noise in hall cables (not saying that it is indeed the problem here, but is a possibility) If the above is the reason, then...

Thanks @flecc for the details and the very informative OP Actually the reason I looked into EAPC legalese was due to a VESC development discord discussion w.r.t legality of four wheeled pedelec. I was under the impression that EAPC is applicable only for 2 & 3 wheeled ones (IIUC, which 1983 law...

Hi flecc, Resurrecting an old thread, Isn't https://www.legislation.gov.uk/uksi/2015/24/introduction/made the 2015 amendment to EAPC ? IIUC the 2015 amendment you mentioned is the one for The Pedal Cycles (Construction and Use) - it doesn't mention 250W replacing 200W for two wheeled and...

I had not thought about it earlier. Though chances are less (haven't come across any case yet), I think it is possible. Just thinking loud, assuming it worn on spectacle (my case), 1. Probably risk factor would be same or less than that of the spectacles 2. Spectacles might prevent mirror...

Handle bar mounted mirror was at times shaky for me (no front suspension). Take a Look mirror was helpful, it can be used left or right side, can be fixed on helmet/specs and can be kept in your pocket. But not everyone will be comfortable with that, it takes some time to get used to it and...

Wondering whether it would be legal for the user to put "legal sticker". As I understand, if there is a proof (say manufacturer's bill) to back it up, it might be okay, but otherwise might get treated as a double illegality - one because of the electrics (over the limit or unknown) & other due...

Cadence sensors would be more prone to failure as compared to throttle. But a cadence sensor failure would not be catastrophic as in the case of open/jammed throttle. Cadence sensor provide a train of pulses under normal operation, the controller observing the continuous pulses (rather square...

Y Yeah, I missed that, if throttle gets stuck other than default position, brake sensor is needed

Even in the highest PAS level, does TSDZ2 stop without any delay ?

Connecting a pull down (say 10K) b/n signal & ground on the PCB can prevent open throttle condition. AFAIK, the only controller having it is VESC based spintend

An option to get the torque sensing work with a generic controller would be to use cycle analyst additionally. There is a controller available that can handle torque sensor as well, https://aliexpress.com/item/1005002711701202.html. It seems suited for Erider torque sensor that outputs 1.5-3V...

So the system detects stlink. To check whether, stlink communication with the processor inside TSDZ2 is working, openocd tool can be used, but it often happens that the one in the Linux distribution will not work & latest openocd would have to be compiled from sources, also the target...

When you plugin the stlink to Linux, are you seeing any logs in dmesg ? On my Linux system, it shows, Note that I use stlink not with TSDZ2 (I don't have it).

Controller estimates rider pedal effort without using any accessories, connections other than the ones normally made on a pedelec. Based on this estimate, it instructs the motor to provide torque (current) in proportion. Please bear with me on not revealing further details about the idea. I...

I had mentioned only in ES forum, that was only last year. It certainly is not me. Get to know better the pedelec user viewpoint, beta testing and feedback, and later if things work out well sales. Product is under development, expecting it to be ready for beta testing in around 9 months.

I am under no illusion that I would be able to make a perfect controller. But my hope is to make a good pedelec controller that can make cycling an enjoyable experience, being aware that people have different preferences and might not suit everyone. This was mentioned on ES, here it started

Initial version of hardware is ready, firmware development is under progress.

At that time, after some rides, the developer in me came to a conclusion that it is a current control one. But I didn't verify it electrically, since I didn't want to mess with my first one & the most popular manufactured e-bicycle here. IIRC, one of the observation was - while going up a...
