Re: VESC for art project

The "shunt resistor value" is not something that can be changed with BLDC_TOOL. So: No, what he means by "change firmware" is to download the sources to the firmware, changing the "shunt resistor" value, and then compiling it and downloading it to your hardware. Still ...

Re: MINI VESC

Hi that's very cool! What are the specs of your mini VESC? Which FETs did you use and which port do you use for flash/debug? Is it mini USB compatible or you had to scrap the USB port? What are the remaining ports? Did you test max voltage and max continuous current? Keep going! If you agree I'll sh...

Re: VESC Overheating ?

Hi, looks steampunk! Do you have a link on the type of heatpipe you used? Is it simple copper bars/tubes soldered onto the FETs or is it gaz/water reaction based inside ? How hot is the large part of the heatsink ? What's the silicon around the wires for, transmitting some heat through them too ? Ca...

Re: FOC max current

Ok I understand better :) Still that's weird because (I looked at your other video) I found the BLDC sound to be less "overbearing" than the FOC high pitch. Like the difference between a plane heard from inside the cabin and a F1 car heard from the pits, well I need to try both IRL :mrgreen:

Re: FOC max current

Ha that's strange how the FOC mode feels A LOT more noisy than the BLDC mode :shock: Okp from ES has achieved a stealth silent result with his board, maybe you should ask him his VESC settings? From same camera distance you almost couldn't hear the board at all and god he has good stuff to play with...

Re: VESC-based board(s) for sale....

Hi, I'm very interested by your modular setup! I need to be able to run 2 VESCs at 6S 70A continuous for now. What would you recommend to up the current safely on your boards? Standard 4.xx layouts seem to meet lot of DRV failure due to temp and voltage spikes ; I'm interested in the safety margin o...
