Working around computers means being careful of static electricity. An ungrounded static spark generated by your clothing or from shoes scuffed on carpet can wipe out an expensive computer component. Many techs simply touch an unpainted part of the computer frame to discharge any static before each contact with a motherboard or hard drive, but that's certainly not fail safe. To protect yourself and the computer, you need an antistatic wristband, properly grounded.

Things you need
- Metal bracelet or watch strap
- 6 inches copper wire
- Wire cutters
- Electrical tape
- 6 feet coiled ground wire
- Alligator clip
- Crimping tool or pliers
- 1-megohm resistor
- Rubber floor mat
Wrap one end of a piece of copper wire around the metal bracelet and twist until secure. Wrap the other end of the wire around one end of the resistor in the same fashion. Snip off excess wire with wire cutters. Wrap both connections with pieces of electrical tape to keep wire ends from scratching your skin.
Take one end of your coiled ground wire and attach it to the other end of the resistor. Wrap with a piece of electrical tape.
Attach the other end of the ground wire to an alligator clip. Crimp the connection with a crimping tool or pliers. Wrap the connection with a piece of electrical tape.
Put the band on your wrist. Clip the jaws of the alligator clip onto an unpainted portion of the computer's frame whenever you are working on sensitive components in the computer.
Tips and warnings
- Place a rubber mat on the floor in your workstation for added grounding and good ergonomics if you are on your feet.
- Don't make one of these without the resistor. It's worth it to pay a few dollars in case the computer shocks you (rather than the other way around).
