"You Don't Know Jack" Hand Buzzers (cont.)
By Nick Vazzana (AKA M3talhead)
Interfacing the handbuzzer with the cab is actually easier than making the buzzers themselves...
|
| First, identify which tabs on the back of the female jack blocks you
need in order to make the connection to the keyboard encoder. You only
need 2 tabs, so once you figure out which ones make contact with the
respective sections on the male jack (at the end of the handbuzzer),
clip the unwanted tabs off and leave the 2 you need. |
 |
| Cut 2 lengths of wire equal to the distance between the keyboard
encoder and where you'll be mounting the jack. Solder each wire to one
of the tabs you saved earlier. If you want to make things a little more
organized, you can make a TWP (twisted-wire pair) by following tip #6
located here. |
 |
| Drill a hole equal to the width of the jack somewhere on or near
the CP and push the female jack through the hole from the inside of the
cab. I decided to place mine under the front face of the CP so wasnt
visible and would keep the lines of the cab clean. Tip: Use a Dremel or narrow file to shape the hole so the jack makes a better fit. |

 |
|
|
| Position the opening of the female jack block so its flush with the
outer face of the cab. Hold it there and fill the drilled-out hole with
hot-glue from inside the cabinet, preventing the jack from moving
around when you go to insert the plug. |
 |
|
 |
|
|
| When the hot-glue cools, run one wire from the jack to the "ground" on the encoder, and the other to an open input. |

Thats about it. Double check everything for continuity and fire up your favorite flavor of "You Don't know Jack!"
