In case you are curious, these four 10' cables will be used to connect these buttons (player buzzers) to the main control box housing the circuitry and this large timer display. The entire apparatus is for a Jeopardy style quiz game to be used my friend who teaches high school science classes. The complete project description is available on my website!
Let's get to it!
Step 1: Materials and Tools
RCA Cable Ends - I got mine from Radioshack because I needed them right away, but you could easily find them online for cheaper, or scavenge old stereo equipment for cables that you don't need and just extend those wires.
Wire - I am using 24 gauge speaker wire that I had in a scrap pile for a couple of years.
Heat Shrink Tubing - Optional
Soldering Iron and Solder
Continuity Tester (or multimeter with that functionality)
Precision Needle Nose Pliers
Wire Strippers and Cutters
Hot Glue Gun - Optional
Heat Gun - Optional
