When there's little humidity in the air, I seem to build up a lot of static electricity in my carpeted office. When I touch any computer peripheral, my monitor flickers, my speakers pop, etc.
I found a old cabinet knob and designed a base to hold it. I found an old 3-wire cable and connected the ground wire to the knob and terminated both the positive and the negative wires.
Now when I sit down at my desk, I can touch this little grounding post to dissipate the charge and safely use my peripherals (SD card reader, KVM switch, etc.)
Note: device needs to be plugged in outside the surge-protected circuit. In other words, don't plug this into the same power strip as your computer.
