Pi Day Hacks - Weekly RecapMarch 13, 2015

As you probably know next Saturday is Pi Day. But this time is no regular Pi Day, it's 3/14/15.

To celebrate this funny and special date we bring you some of the coolest hacks and news we have found around the web regarding the Pi world.

But first things first: What is Pi?

Pi is one of the most famous numbers in mathematics. It is an irrational number (infinite decimals 3,1415...) that describes the ratio between a circle's diameter to its circumference. Florian Born and David Friedrich have designed and assembled a machine that calculates the number by mechanically controlling an old calculator. Check out this project here.

Vintage and nostalgic application with Raspberry

Here's another example of how you can re-use old technology and integrate it with Raspberry Pi. Voidon took a rotatory phone and converted it with a Raspberry Pi to VoIP. He removed the parts he didn't need to make room for the board and used a USB-sound card for the microphone and handset audio.

He used the GPIO for to read the rotatory dial and to detect on/off hook of the phone. Posted on hackaday.
