Building Game-Show Controllers for You Don't Know Jack
Hand Buzzers

What You Need:
- About 1' of 1/2" PVC
- Hacksaw
- Soldering iron and solder
- 6 endcaps for the PVC pipe
- PVC cement (optional, if your PVC fits tight without it)
- 1/2" drillbit and power drill
- Momentary pushbutton (Radio Shack cat. number 275-609A)
- 3 cables: 1 end with 1/8" phono plug (2-connector), the other end bared wire (Radio Shack cat. number 42-2434)
- 3 1/8" 2-conductor phono jacks (Radio Shack cat. number 274-251C)
- Optional: 15-pin female VGA connector (Radio Shack cat. number 276-1502)

Preparing the PVC
Peel the price stickers off the endcaps. Drill a 1/4" hole in 3 endcaps. In the other 3, drill a 1/2" hole. Cut the PVC into 3 lengths of about 4".
Wiring the Buzzer
Take the bare end of one of the cables. Run it through one endcap (one with a small hole, from the outside-in), then through the PVC tube. Take the hex nut for the button and run the cable through it, then through another endcap (the one with the big hole, from the inside-out). Finally, solder the bared ends of the cable to the 2 tabs on the pushbutton.
Assembly
Once you are sure the button is soldered well, push it through the hole in the endcap. Screw on the button's hex nut. You might have to use some needle-nose pliers to rotate the nut. Once the button is tight, push together the rest of the PVC parts, and the buzzer is done.
If you want to play right away...
If you are Jack-happy, you can attach one or all the buzzers to your modified keyboard. Attach a 1/8" jack to a female 15-pin VGA connector, and plug that into your keyboard. You can probably attach 3 jacks to the VGA connector to accomodate 3 buzzers.
Of course, the final project will be much more refined. The keyboard will plug into the Console with a standard VGA extension cable, and the buzzers will plug into jacks on the back of the Console. But if you don't want to wait to finish the console to test your work, just attach jacks to the keyboard and plug your buzzers in.
