Hand Buzzers

The hand buzzers themselves are made out of 1/2" PVC cut into 4" lengths with PVC endcaps on each end. On the bottom endcap I drilled a 1/4" hole (for the wire to fit through), and on the top endcap I drilled a 1/2" hole (for the pushbutton to be mounted). Once the PVC was cut and the holes in the endcaps were drilled, I spray painted everything black.

I took the bare end of a Radio Shack Shielded 6-Ft. Audio Cable with 1/8" mini-plug and ran that up through the bottom PVC endcap. I then took a Radio Shack SPST Momentary Pushbutton Switch and screwed it into the top endcap. I ran the cable through the PVC length, attached the bottom piece to the PVC, soldered the bare ends of the audio cable to the pins of the pushbuttons, and then attached the top endcap to the PVC. It sounds a lot more complicated than it really is. This picture should hopefully help explain what I'm trying to say here.

The 1/8" mini-plug audio cable coming out of the hand buzzers plugs into the 1/8" panel-mount jacks that are mounted toward the bottom of the Button Box. So pushing the button on the hand buzzer closes the circuit in the I-PAC VE that's inside the Button Box, which sends its signal via USB to the PC. Easy as pie!

The hand buzzers add a lot of "authentic game show" gameplay to YDKJ. Plus, I have to admit that there's nothing quite like having actual hand buzzers for the Jack Attack at the end of the game!

Up close.
All three buzzers.
In action!
