Migrating to julip.co

I’m in the process of migrating my online identity to a new domain. I’ve changed my main email address to me@julip.co and my website to http://julip.co/. All the old ones under julianapena.com will still work and redirect to the new one. A special thanks to Go.co for giving every participant in Startup Weekend Medellin a free .co domain. :)

Arduino & Python Soundlight Spectrum

Continuing with my initial Soundlight project, I have modified the code to produce six distinct lights depending on the frequency of the music! Why six? Well, that’s the limit of the Arduino’s PWM (analog out) pins, so that’s as much as you can get with a single Arduino Uno. It works by using Fast Fourier Transforms to analyze the sound frequencies and find how much sound is coming out from each frequency range (special shout out to Luis for helping me understand this beautiful math!)

Here’s a quick demo video:

Memechat: Use ragefaces and memes in Gmail and Facebook chat

Memechat on GmailMemechat on Faceboook

Have you ever wanted to use ragefaces or memes like Forever Alone Guy or Philosoraptor in Gmail or Facebook Chat? Well now you can! Using my super handy Chrome extension, just type ra.ge/[keyword] in your chat and the extension will automagically convert it to an image.

Examples include ra.ge/forever (forever alone), ra.ge/praptor (philosoraptor), ra.ge/fu (classic f7u12), and ra.ge/megusta (ME GUSTA face). For the whole list, visit http://bit.ly/allrages and http://bit.ly/allmemekeys

Note: Both users will need to have the extension installed to see the rage faces and memes.

Get Memechat at the Chrome Webstore

Open source! Grab the code at GitHub. Based on the Facebook rage face extension by josePhoenix.
