I just finished taking part in SparkFun’s Free Day. I was able to answer 8 questions before the $150,000 ran out so I won $80 plus another $16 for charity! The servers were completely bogged down for the first couple of hours and I only managed to answer a couple questions. Then the servers became unresponsive according to one of the admins in #sparkfun, but when they came back I was able to rush through 6 more questions before the money ran out. I would have liked to get to $100 just for the satisfaction of completing the quiz, but $20 less for me means a couple of people got $10 each.
Thanks Spark Fun!
