Re: I'm looking for developers/engineers interested in high current (+1kA) controller development
Did progress ever get made on this project? I've been playing around with instaspin recently for fun (strange idea of fun I know). I've been working towards getting a controller going with the 28004x.

Re: Single stage RC left hand drive
Nice parts, I really like the brake/sprocket adapter.
Is regen or braking possible on the castle controller?

I bet there's a tip that can do what you're after
Doesn't it just use a resistive heating element like most other stations?

Re: phaserunner error code 1-8
Surely the controller is bad since you get normal values with the good PR on the same motor.
You can try measure the voltage drop across the body diodes of the mosfets with the dmm diode tester and see if there is anything funny there.

Sorry I meant measure the voltage with your multimeter and see if it agrees with what the controller reports.

Re: phaserunner error code 1-8
Of course the controller is not going to drive the mosfets if one phase is at a very low voltage. Have you actually measured the open circuit phase voltages with the controller powered on?
I see you have measured the phase to supply negative resistance with a dmm and not found any shorts.

Re: 'unlock' ASI BAC 4000? (Surron controller version)
The ASI software is actually called "Bacdoor". It's available for PC and android but the android version requires a valid ASI account and password (which you will probably not get). Also keep in mind that it is possible for a vendor to password lock a controller, in which case you will not...

Re: Daisy chain active balancer
I believe the problem with these switched inductor and capacitor balancers is that the balancing current is proportional to the voltage difference. So my understanding is that the balance current tapers off and it gets quite slow as the cell voltages get closer.

Re: Linux geeks thread
What virtual machine software can do a gpu passthrough? i'm intrigued! Check out the vfio kernel module. You use the vfio driver on the display you want to pass through. Then you can just add the pcie device in qemu the usual way. The performance is pretty darn good. To me the performance in games ...

Re: Linux geeks thread
I've run Linux on my laptops and desktops for a few years now. Distro hopped a bit initially but settled on Fedora with Gnome as I like their release cycle but with frequent kernel updates which is nice on newer hardware. Also use a windows vm with gpu passthrough for gaming and other windows only s...

Re: Bosch performance line adding halls
The waveform from the hall sensor with the motor spinning should be 50% duty cycle as the rotor magnets toggle it on and off.
Is the vesc able to detect the hall table?

Re: VESC Field Weakening
You would need to compile the vesc controller firmware and vesc tool program to use that branch. I'm not sure if that branch should be used for field weakening as only the MTPA code has been merged and not the FW part. I've implemented field weakening on my ebike a different way and have been riding...

Re: New ground-up ESC - MESC_FOC_ESC
Hey congrats on getting a motor spinning from scratch! Your project seems like a great way for people to learn motor about motor control. Arguably easier to get into than the available dev kits made for that very purpose.

Re: Neu 8057 6kW left hand drive hardtail with vesc and encoder
Tweaked the fw a bit so that Iq decreases smoothly and there isn't that odd surge in power at high speed. Motor power and voltage are now more constant in the field weakening region.
