Creating jumper leads from ethernet cables - connect multiple components












2















I've bought some crimpers and a dupont connection kit and I'm planning on reusing some old cat5 ethernet cables I have.



Is it reasonable to connect two devices to the RPi via the 8 wires in the cat5 cable? For example connecting four jumpers to 4 GPIO pins on the RPi connecting to one device and the other four cables in the cat 5 cable to four other jumpers on the RPi connected to a second device?



This is attractive because it keeps the wiring (that will be visible) reasonably tidy but I'm not sure if this approach is technically appropriate.

          Lots of folks do that.



          You may need to add some small capacitors on long cable runs to reduce and RF interference that a long unshielded cable can pick up.

          ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

          Image
          0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited. ...
