Typically, a user should create a pointer to a cfg_struct, initialize it with cfg_init(), and then perform actions on that object (lookup, add, delete) by passing the pointer to the functions here. At end of use, call cfg_free to clean up the object....
Two weeks ago, I set off to a business trip to Germany, which is also my home country. I always try to have a few days of vacation included in such a trip in order to be able to visit my family. And what does a father with his son living in another country...
There's an old hard-disk which I stripped down so that the front only has spindle coming through. I used a mill to face off some of the protuberances and other features which held the read/write head-arm in place. At the bottom there is a PCB I...
Here's a video of the project:Here is a diagram of the main components:The system is comprised by a computer, a webcam and a video projector. The camera is placed on the ceiling, above the pool table. It's very important that the camera is positioned...
Half of a two-part project, the other part being "OBA on a Toyota."A friend of mine is making a short film which requires some simulated explosions. Since he doesn't have an explosives lisence and we will be shooting some scenes on public property and...
I've wanted to build my own amp for quite a while. For bass guitar, the selection of amplifiers you can buy is pretty lack-luster, and mid-volume studio amps are hard to find. It seems like most of what's available is either a practice amp or a stadium...

The MeArm is an Open Sourced Robot Arm. It's small, like pocket sized and that's for a reason. It can be cut entirely from an A4 (or more accurately 300x200mm) sheet of acrylic and built with 4 cheap hobby servos. It's live on our site for about $35...
I bought an XMS amplifier from a friend years ago and although it was serving it's purpose I got quite frustrated with having to toggle the loudness feature every time the input was changed. This was the beginning of what has now become my network enabled...
I picked up the vacuum system from Portland State two weeks ago from a professor I know. It was too big for the little things they do and by the time it warms up and pumps down there is no time left. So they decided to get rid of this system and build...
Media artists often need to play multiple videos on multiple screens in loop for long time. Often they also want to play all videos synced (i.e. all of them starting at the same time). Having one device (for example a computer) playing all videos requires...
In the original configuration, the airswimmer is propelled by the tail fin, which can be flapped left-to-right using the remote. The whole fish can also be tilted up or down by moving the gondola, which holds the battery and receiver, forward and back...
IntroductionVaporization is done by off-the-shelf ultrasonic atomizers, either really cheap ones (the black ones in the picture below, 2.50 $ each) or some more rigid ones (the silver one, a Fogstar 300, 290 € each), air is moved by an array of...
