KapaLa Moksha: Microcontroller based Quiz Buzzer

devadutta @ 1:27 am, GMT +0000 ( 1237771647 ) Play

A few months ago, I conducted a Kannada quiz for the Sacramento Kannada Sangha. Since people were fond of buzzer rounds, they requested me to have one. I hate buzzer rounds because it is very hard to arbitrate who hit the buzzer first. To solve this problem, I rigged up a micro-controller based Quiz Buzzer which talks directly to a computer via RS232 and clearly displays which team hit the buzzer first! Since we had a huge screen and a projector set up at the location, the entire audience could see the team number as soon as someone hit the buzzer.

I got some overwhelmingly good response for the buzzer and I decided to make it available for download. You can read more about it here:

KapaLa Moksha — Quiz Buzzer v0.1

This is how the hardware setup looks(ed)

d3a083a06a81f6f8957cd1d8a77ef44a

and it comes with software which can display the team number which hit the buzzer first on a Windows based computer. Here is a screenshot

More info and downloads here. It is released under the GNU GPL v2.

All feedback welcome!

Guest question from p vs np. Thanks again dude!

Some places have contributed one each to it. Just one university of repute has been capable of contributing one from its side. Furthermore, some distinguished scientists of the 20th century were also only capable of contributing just one each to it.

But a little mine in the village of ‘x’, which lies in the district marked in red, has the unique distinction of contributing nearly half a dozen to it, all by itself !

Solve for x.
