Maker and Thingiverse user Ron Provis decided to design and build a set Quiz Buzzer Buttons that his family could use during games to avoid arguments. The buzzer is mostly 3D printed on his two home-built 3D printers, affectionately named Big Dweeb and Little Dweeb. The lights and buzz sounds are programmed with Arduino, and he also was able to include a digital due caster into the buzzer.
