Blair Hollands, a professional quizmaster and Game Show Presenter customer, created his own wireless buzzer system and sent us this picture. The buzzer buttons (shown above in a carrying case) can be placed on the tables in a pub or event room, then teams of players buzz-in if they think they know the answer to a question. The wireless buttons send number keystrokes 1 through 6 to the 6 USB receivers plugged into the USB hub. That plugs into the laptop and can communicate directly with Game Show Presenter. This is one of the most professional looking "home-made" buzzer systems we've seen!
