quiz show buttons

Since I know nothing about electronics, I took up the challenge to build quiz show button system for deskidance It consists of 16 buttons, indicator laps and a control panel. Whenever a button is pressed, the light goes on and the other buttons are locked out, hence you can see who was the first to press the button. It was a heck of job, there’s nothing like debugging electronics after all night soldering session. It runs on 8 dual JK switches, 2 8-way NOR gates plus an AND gate. One thing I learned in the 2 weeks build is that next time I’ll use a ready made micro controller ;)
