$160??? Come on! What’s really the cost here? And please don’t start comparing to GoPro’s price, it just proves my point even further.
Edit: Also, why make me pay for the lens, especially a fish-eye one?
News - Free Day 2012 Recap

Don’t forget that some people won within the first minute of trying and for each one of those there are others that spent the entire time trying without getting anything.
oh, no one needs to code a single command. Sparkfun could provide the code that people would download and run. If people feel like messing around with the code, that’d be fine as long as they would abide by the rules (or get banned).
I’m not really sure how one might modify the code to gain a tiny bit of advantage without breaking the rules though.
ok, this might be the lamest protest ever. You brought “whining” to whole new level!
Also, a suggestion (my turn to be a smartass ;) :
Randomization seems fair, but captchas just suck. They’re merely there to ensure that everyone has an equal chance against the geiger. If that’s the case, then you probably don’t really care if it’s really a human or a bot on the other side, as long as everyone has an equal chance.
If that’s correct, then why not let people use a bot that polls the geiger every, say, 4 seconds and block (iptables) offenders for 10mins the first time, 1 hour the second time and the rest of the day the third (if they try to poll faster than every 4secs).
This way there would be no captchas and I’m sure people would enjoy far more watching their bot at work. Not to mention it would more fair to dyslexics and people who can’t type as fast but love SparkFun just as much! Just saying… ;)
Wow, my analysis from yesterday (based on pachube) was right on the money!
If we distribute 2000 awards evenly in a period of 6h, you get about 1 award every 10.8secs.
At the rate that SF received successful attempts, there would be about 3,200 attempts within that time.
Within the same time you would have made about 2 successful attempts on average, which gives you a probability p=1/1600 every time.
If you plug this into a binomial, you’d still need about 1,000 attempts to get a 50% chance of getting at least one winning one.
at about 1 attempt every 5 secs, this would take about 1h20mins (just for a 50% chance).

The geiger is irrelevant, it’s mostly there to create additional buzz and to ensure that wins are awarded based on a poisson process (which is more fair than what a random function would do).
Also, see my edits for more info.
Your CHANCES OF WINNING:
total: 6,000,000 attempts (excluding failed captchas)
that’s 1m attempts per hour.
that’s more than 270 attempts per second!!!
Even if you’re SUPER-FAST you need more than 2sec on average per attempt.
On average, you’d have to sustain this brain-killing, finger-numbing rate for 10mins before wining (on average!).
However, you’d make mistakes too so I would expect at least twice that time (again, on average), which is not too bad.
I could verify that your chances were “not too bad” as follows:
there were 6,000,000 attempts
assuming that people made about 100 attempts (some many, many more, but others gave up much earlier than that), about 60,000 unique people participated.
the chance of winning then would be 1/30, which again is not impossible, especially if you made more than the average number of attempts.

at about 1 attempt every 5 secs, this would take about 1h20mins.

Files for the acrylic case design please? Any recommended accelerometers to trigger the time display?
Also, here are the steps I followed to put it together, with a slight variation on the part of assembling the case which made it easier for me:
