I'm just your typical poor college kid living on ramen noodles. I'm a Computer and Electrical Engineering major so one can only imagine the levels of nerdom reached behind the door of my apartment. I also work in tech support at a electronics store, arming me with endless stories of funny and horrific technology mishaps... So tune in and enjoy nerd blurbs, random ideas, and funny stories.

Teardown violates Google Glass’s right to privacy
Wonder what makes Glass tick? So did electrical engineer Star Simpson and software engineer Scott Torborg, who took their Torx drivers and spudgers to Google’s headset in order to find out.
user632
Public installation piece from undef in public window collects data of of it’s audience with a Kinect sensor - video embedded below:
User 632 is an installation that stores the behaviour of the people who look at it by monitoring them in return. It wants to know when and how a person passes by or if they stop on the way.
All data is being tracked and displayed publicly. Passers-by are stored as an anonymous number without any hints to their identities. Whoever comes to close to the camera though will be stored with a photograph next to their id.
The installation is made up of three Kinect depth cameras that constantly look for movements which are then reduced to a simple directional line in space. When a visitor enters a specific area, the algorithm is looking for a face. As soon as one is found a countdown appears that shows the time until a photo is taken automatically. At the same time the time a user is in the visible area is stored.
This data (time, path and eventually image) are stored in a database, interpreted and displayed as real-time statistics.
Walkmac revisited: The inside story of the ‘first’ portable Mac | Fully Equipped - CNET Reviews
A spring cleaning unearths a semi-rare Apple find, the Colby Walkmac, a “modded” portable Macintosh that predates Apple’s Macintosh Portable.
Changed my setup a bit and tweaked my hot/cold LED code to now wake up my laptop after I’ve been sitting in front of it for 300 cycles (just a few moments)
I got this C-Control Robot System RP5/RP6 Robby robot chassis
from Amazon and hooked it up to my Pi and Pi Face. I’ll be publishing more details later
How to output letters A-F and numbers 0-9 on a 7-segment display using an Arduino (written in Verilog) Enjoy!!!
