Toolbox: Portable workbench
My friend, and fellow Dorkbot DC and HacDC cohort, R. Mark Adams made this simple portable workbench out of plywood and basic hardware. He added some nifty features, like a wire spooler underneath the hinged top (with tool storage inside), two working angles (a drafting angle and a flat-top work surface) using hinged “ears” to […]
Pseudo-3D video conferencing
Chris Harrison and Scott E. Hudson of CMU’s Human Computer Interaction Institute developed a technique for simulating a 3D video conferencing experience using standard webcam equipment. Previous research efforts have explored the use of 3D in telecommunication, and show that the additional realism can enrich the video conference experience. However, existing systems require complex sensor […]

How-to Tuesday: Arduino 101 blink an LED
This week is the first part of a series about getting started with the Arduino. A few weeks ago I posted a quick how-to on using a force sensor with an Arduino and I received a lot of positive feedback. This led (no pun intended) me to the idea of a creating a series of […]
DIY cable light connectors
MAKE contributor Bill Bumgarner has posted another great home project, and it’s chock full of fun things like a tap & die, drill press, and cross-sliding vise (and lasers): While making my own low voltage cable light fixtures, I searched high and low for a little piece of hardware that would elegantly connect between the […]
1 terabyte RAID in a MacBook Pro
Damien Stolarz, co-author of the upcoming iPhone Hacks and author of Car PC Hacks, has crammed two hard drives into his MacBook and likes to live on the edge: I bought two nominally 500GB hard drives (amusingly, each enclosure contained a different manufacturer – one Hitachi and one Samsung). Then I purchased an adapter from […]
