The name “Game Show Buzzer System V2” is a misnomer but I’m gonna go with it… See, I’ve built more than one “Game Show Buzzer” type of system since the original post but they were not documented here for various reasons… Anyway, this is a system I designed quite a while ago but just recently had someone actually want, so I built it.
See, typically I sell one (or more) of the Big USB Buttons or even these Survey Says Buttons, but this system doesn’t use multiple individual self-contained buttons, but a control box you can plug multiple buttons into. This specific system has just two buttons but the original design had either three or four, though doing up to six (or even eight) buttons would be trivial.
The control box plugs into a computer via USB and can send keys, keystrokes, USB MIDI data, or serial data. Each button plugs into the control box using a TRS cable. (That’s a 3.5mm Stereo Cable for you non-nerds in the crowd.) The TRS cable has three connections (Tip, Ring, and Sleeve) which is perfect for a button and LED.
The trick is in the code… meaning the programming is whatever is needed. For this specific build we did a USB MIDI noteOn for each button, followed by a five second lockout so no button could be pressed for five seconds. I’ve done systems where the “host” (using the control box) can reset the system, say for instance if the person/team who buzzes in first gets the quiz answer wrong, so that another team can try to buzz in and answer. Lots of possibilities, again, the magic is in the code.
I’ve built enough of these that I really should formalize things and come up with a system where you can choose the components and features and then place an order… It’s still sort of a custom thing (code always is anyway) but I think I have it down enough that a base system is in order.
Anyway, this was another fun project, though it was a bit rushed (got it built and programmed in a matter of days before it needed to ship) so there are a few small improvements I’ll be making next time.
