The Monthly Challenge: Audio Hacks

  Follow me to hear about all of the Monthly Challenges.


This Month's Challenge:
Share a hack that somehow involves sound.

 

I know that a week is a short time to do a great project and I wanted to start giving people more time to get their projects together, so I have decided to turn the weekly challenge into a monthly challenge. What this means for you is that you will now have more time, more chances to win, and better prizes. I am looking forward to seeing everyone's awesome entries.

 

The winners are now in. With so many awesome entries, it was hard narrowing it down. That said... narrow it down I did. Here are the winners. Thanks again to all who entered!

Awesome job everyone on getting 61 entries in! That means there will be 7 winners in all. Good luck to all those who entered. ;)

It appears he only picked two...

...what happened to the other 5?
Mar 7, 2012. 4:29 PMcanucksgirl says:
There's 5 "Honorable Mentions". I would imagine they received prizes as well. ;)
Mar 7, 2012. 4:52 PMblinkyblinky says:
Well, either one of them have not (moi) or, they will not.
Mar 7, 2012. 4:59 PMcanucksgirl says:
Oh. I see now you were one of the "honorable mentions"... I could be wrong, but when the tier level prizes were posted, I believe there was 7 winners in all (due to the number of entries).

I would suggest sending a PM to randofo to confirm, and/or check your Instructables Inbox, and your email account (in case he sent you some info).

Since the prize list has been removed, there's nothing I can refer to now.

Under the official rules:
Tier #3: If there are at least 50 but no more than 99 entries, the entrant with the highest judges’ score will be awarded a Fujifilm FinePix Real 3D W3 Digital Camera with 3.5-Inch LCD, a 1-year Instructables Pro membership, a Sugru sample pack, and an Instructables robot t-shirt. Approximate retail value: $400, £ 257.32. The entrant with the next highest judges’ score will be awarded a prize package including a Sony BDP-S480 Blu-ray Disc Player, a 1-year Instructables Pro membership, a Sugru sample pack, and an Instructables robot t-shirt. Approximate retail value: $165, £ 106.14. The entrants with the next 5 highest judges’ scores will each be awarded a prize package including a 1-year Instructables Pro membership, a Sugru sample pack, and an Instructables robot t-shirt. Approximate retail value of each prize package: $65, £ 42;

so blinkyblinky, if there were 61 entries.. your Octosynth should have won you, pro membership, sugru sample pack, and T-shirt!! I'm sure it all takes a bit of time to process. Congratulations!!!

Number 15 for me (saving the best for last) -

http://www.instructables.com/id/Adding-a-VU-Meter-to-your-PC/

I've got over a dozen halfway finished Instructables, but I'm pretty burned out so I'm pretty certain this is going to be the final entry for me in this month's challenge. Maybe if audio is a challenge again or something where there's enough overlap I'll finish them.
