I built Game Show Buzzer System V2 earlier this year, and I had someone who wanted basically the same thing, so this is Game Show Buzzer System V3 with a few very minor tweaks. I’ve added LEDs into the control box so the host can see which player buzzed in.
Once again 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. We used 6 foot but you could easily get 10 foot or longer if needed.
For this one the client will be using Resolume VJ Software & Media Server and each button is set to send a different MIDI noteOn signal to trigger a video to play. Like any game show if you hit your buzzer first you get to answer the question! In discussing functionality I explained how we usually have a “lock out” time before another button press will be recognized. The client thought a three second delay would be fine…
But! I mentioned we could always adjust that in the firmware later if needed… Also, I added a reset button directly on the control box. This would allow the “host” to press the button to end the lockout period. This is sort of a future-proofing feature.
I think if I were building a deluxe version I would add a control to set the lockout time… something like what I did for the Tradeshow Video Player Controller perhaps. But also, am I getting ahead of myself? Since I haven’t built it yet I will say “No” but then…
Also, this could be used as a standalone system without a computer. It’s less exciting, as there is no sound or video triggered when the button is pressed, but as a bare-bones quiz game system, it would work fine. If you do want sounds it would be trivial to plug into a computer via USB and use QLab or LeMIDI for those.
I started working on a four button version of this, but now I’m thinking I might want to just build the deluxe version and hope that someone might want to purchase it in the future.
I’m also considering different button options, as these are nice and big but they’re also fairly expensive. We could use The Button or any other button for triggering things. (But yeah, people certainly like hitting that big button!)
