Love to recycle and it will last 4ever. I used an old wire harness for mine.
Step 1: Materials
You will need some wire, solder, soldering iron, wire stripper, heat-shrink tubing, a heat gun or matches, and a pendrive
Cut wire to desired length and string through pendrive. Short wire for dongle (around wrist) or lanyard (around neck). I like the yellow and red wires.....pick your favorite color(s).
Cut a piece of heat-shrink tubing and slide over wire BEFORE stripping wire ends. THEN strip the ends.
Make a lineman's splice as, illustrated by my crude drawing, with the two ends of stripped wire.
Solder the lineman's splice with a thin coating of solder.
Pull heat-shrink tubing over the splice and heat it up with heat gun or flame to lock into place.
Kick back, crack a cold one for a job well done
