The Ultimate Altimeter

Last day of Butthouse!

OK. I signed up for an online Secret Santa thing with redditgifts, and my giftee was into RC planes and such. I made this Altimeter for him, and published how I made it. Check out the Instructable: http://tinyurl.com/UAInstructable

Also, you can vote for my post (top right corner of the post) if you think it is worthy. If I win we get free stuff!

Bye.
