Amazing Ideas For DIY USB Hub That Will Make Your Life Simpler

DIY USB Hub:

The USB or the Universal Serial Bus port is a plug and play interface that allows a computer to communicate with peripherals and other devices. A USB hub is the easiest way to expand the number of USB ports on a PC or laptop. These are typically used to extend USB sockets to the top of the desk to conveniently plug in USB drives, cameras and portable storage drives. In the age of the DIY, the USB hub hasn’t been left untouched either. You can make a DIY USB hub for plugging in all of your devices and gadgets easily onto your laptop or PC.

Here is how:

Materials

  • A Cat5 cable with one RJ-45 connector (you can use an “Ethernet” cable cut in half)
  • An FTDI USB-RS422-PCB board
  • A 2-3cm diameter clear shrink tube cut to 3cm length
  • A 1-1.5cm diameter opaque shrink tube cut to 2.5cm length
  • Soldering iron
  • Solder
  • Wire cutters and strippers/ knife)
  • A heat gun (or hair dryer, or lighter to heat)

  • solid green
  • green/white
  • brown or brown/white (doesn’t matter)
  • The green pair carry the serial data from the hub to the reel.

  • Place the clear shrink tubing over the assembly so that about 2mm overlaps with the USB connecter. Blast it with the heat gun for a snug fit.
  • Slide the opaque shrink tubing over the assembly so that it overlaps both the board and the sheathed part of the Cat5 cable. Blast it with a heat gun so that it fits snugly.
