[Entry] Frequency counter

This is my submission to the 7400 contest. You can find a detailed write up on my website. Looks like I can't post this because I am a new user. I already had my account deleted within 5 minutes of creating it! I hope its not because of my all numeric username!

I tried to submit this through the online forms (DP contact page and the 7400 submission page), but the submit button doesn't do anything...

I'll link everything in once my noob timer expires.

Cheers,
Yi
