Do you have a physical connection between invert case (gnd) and system ground? Ideally, ground every bit of electrics apart from your HV to the inverter case. Your +, -, Gnd connections on the PSU are ok, just treat '-' as your ground. Connecting your PSU to a car battery, and then to the inverter w...

There is (I'm 99% sure) a 'history' function, so any changes can be blamed on the correct victim can be reverted if needed

Perhaps a typo? Note "last active"

My cheapy LHT00SU1 + pulseview has been fantastic. Several digital channels (pulseview supports various protocols) plus 1 analogue (-10 - +10V from memory). No good for HV stuff, but great for the low voltage side. Plus, if you plug it into a laptop and unplug the laptop charger, it becomes isolated...

Given the (likely) low power of the motor, the easiest way of driving it would probably be a largeish RC brushless speed controller. Most of them run sensorless (no need for the resolver) which would probably be fine unless you need precise low speed control. If you want/need to use the resolver, an...

Three thick wires, four thin wires? Sounds like a 3 phase motor with a resolver

Got a vacuum bleeder? Or a pressure bleeder? I know it shouldn't be needed, but makes things a lot easier, especially when the system's dry.

Democracy is incredibly inefficient

Yes

Nice, good debugging to find that (far from obvious!) problem

I sincerely hope that's a joke...

It does all depend on what Vq (etc) actually is, doesn't it.. I must admit, I'm totally lost :-) Kv is normally defined as a ratio of peak (battery) voltage and rpm but it's more of a 'laymans' unit rather than proper SI. Peak/battery voltage makes sense to me, but it seems these things are quite of...

mmmmm grungy

That looks a little better haha

It's amazing these things work as well as they do with all the gunge in there. Fixable with a clean and new seal kit?

The ultimate solution would be changing the pwm frequency continuously, generating (white?) noise instead of a fixed pitch tone. But that would need massive changes to the Open Inverter code...

It could be worse of course, you could be stuck at 4 or 8kHz...

If there is to be another release, lines 406 and 407 in mainwindow.cpp should set Vb and Vc I think (current sets Va to 0 three times )

I'm impressed!

I'm pretty pleased with that guestimate Although surprised it's actually that heavy! You need a carbon fibre one for performance

Old - 50lbs
New - 7.2lbs

haha

At least they didn't paint it silver for you

Not a twitter/Elon IP was it?

Careful not to trample on the wifi stack, safest just to leave that core alone if you're relying on OTA

Can do multiple xTaskCreate's on one core though, if that's any help.

I was more thinking of use the ICE input for the PTO - MG1 will drive it quite happily. ~60kW apparently?

I've not tried this, but my first instinct would be to use an RTL-SDR with a directional antenna and wave it around...
