Lost in place: iPhone screenshots of grid system

Wednesday, February 17th, 2010

IMG_1399

IMG_1402

Two screenshots from my phone depicting the grid underneath the Google Map graphics which are tiled to create the map interface. Clearly, the “virtual GPS” technology on my first-generation iPhone has often been helpful in finding my way. But what happens when it fails and you are literally lost in space? The social landscape, politics, climate, language(s), culture are what we analyze to understand “where” we are. Without these points of reference how can we create an idea of place? In this case, the simple query, “Tallahassee,” can be enough for any individual slightly immersed in Southern culture to create a perception of this place.

Today I launched the public alpha version of my Facebook application Give Me My Data for testing and feedback. This app helps you reclaim and reuse your Facebook data.

Feel free to test it and let me know what you think!

Facebook Death Star

Friday, November 13th, 2009

Here are two images I created with NodeBox (Python) and PHP (data via facebook API).

facebook_network_graph_bigcircle
All friends, one common link.

facebook_network_graph_mutualfriends
All the mutual connections I could gather before the script timed-out. Need to make the gathering more efficient.

Two stepper motors, one directly connected to PWM on BBB

Thursday, July 30th, 2009

Testing to see if this motor can connect directly to PWM on BBB (Freeduino).

Code embedded in previous post.

BBB (Freeduino) and stepper motor test
