Mike, aka Mrsuperpants, built this quiz buzzer system to use at a friend’s annual BBQ shindig. Built mostly from extra/scavenged parts, the setup sports light/sound indicators and some “sparkly holographic covering material” – sure to be a party favorite. – Quiz system

I’ve got to start documenting my projects.

I built a trivia buzzer using the 6 remote controls from the Hasbro game “Remote Possibilities”. I used an Arduino for the receiver and an RGB LED for the display so the LED lights up the colour of the remote that was pressed.

If you actually read right down to the bottom of that page, looking for the description of the circuit, you’ll find that it’s unfinished. There’s no relay logic in it to determine who buzzed first, just the buzzers and lights. Shame. Oh well, I have some ideas for making one of these gadgets with a few SCRs and no need for any relays. Will have to press on with that, and write it up!

It’s actually a very simple thing to build, I’m not sure what you mean by relay logic, maybe 1940′s computer technology?

Popular electronics had an article on this I built many years ago. They used a 8-bit latch; connect 8 buttons to the 8 inputs and some kind of SCR to hold it latched once triggered.

More recently, I’ve done it with PIC chips and now Arduino. It’s a very, very simple program, basically “monitor the pins, if something changes, latch it, light the correct output and make a noise, then wait for a button press”.

  Did you ever have time to document your Remote Possibilities Hack.
