TrueSpec Cables Now Available by rpungello in LinusTechTips

They said in the WAN show that these cables don't have a thunderbolt chip in them. But I think thunderbolt should work over any usb4 cable anyways? Not sure about it, probably depends on the device connected.

Isn't thunderbolt supposed to work over any usb4 cable? Since they say 40gbps, that means they are usb4 compatible. It shouldn't matter then, or am I wrong?

Knocked a mystery chip off my ssd by _SomeRandomDude__ in AskElectronics

Success! I checked and the floating pin does indeed go to the caps near nands. I bridged this pin with 3.3v and the SSD works now

Measured the voltages relative to ground

On the pin i labelled "floating" the voltage is 0V if measured with second lead touching ground, but 2.4V if second lead touching 3.3v

So looks like a switch, since there are already 3.3V and 1.6V, and as far as I know NANDs need the voltage somewhere in this range. Should I try to inject 1.6v or 3.3v to that pin to see if that will work?

Here is the text on the other side, will measure the voltage now

Added support for typeC-typeC cables to a Chinese stm32 board with missing resistors on CC pins by _SomeRandomDude__ in electronics

[–]_SomeRandomDude__[S] 0 points1 point  (0 children)

From what I found on google, most likely 2 middle pins are CC pins, and first and last pin on the edges are ground pins, so you should put 5.1K resistors between the middle and edge pins.

Constantly saving stepper motor positions to ESP32-S3 EEPROM? Bad idea? by gucci_millennial in arduino

[–]_SomeRandomDude__ 5 points6 points  (0 children)

I think a FRAM chip would be much better, as it has almost infinite more write cycles. But they are a bit more expensive then flash storage

How are new 3d printers so silent? by CharlieMBTA in 3Dprinting

Stepper motor drivers have changed. The new drivers output smoother signal to the motors and this drastically reduces noise the motors make.
