How to add joysticks to HTC Vive wands

There's a solution for those who feel the touchpad is lacking.

The HTC Vive is one of the premier PC-based VR systems on the market, and part of the full package are two motion controllers, colloquially called "wands." Each wand has a touchpad on it that allows for locomotion and menu navigation, and while it works well, some feel that a joystick makes a bit more sense. If you include yourself in that camp, I have a solution that can help easily (and cheaply) add joysticks to your wands.
