Wow, this Augmented Reality technique looks like it works very well! Via: Procrastineering “Video results for an Augmented Reality tracking system. A computer tracks a camera and works out a map of the environment in realtime, and this can be used to overlay virtual graphics. Presented at the ISMAR 2007 conference.”
If you need to measure household AC voltage with your grounded scope this Differential Probe Project might work well for you.
Most of our workplaces are built using wood, metal and plastic. Adding some plants can go a long way to make the space a bit more comfortable. Have a look at the Bio Computer over at Total Geekdom. In this design the computer is used to help heat the soil to promote germination. Â “I started wanting to use the heat from a computer as a way to warm the
Like so many people these days David Prutchi has a space communications array in his back yard. His modification of his FTA dish allows it to be used to receive Ku-band transmissions from geosynchronous FTA satellites as known-Az/El beacons. “The Fortec Star 120 dish is small enough to be handled by a Yaesu G5500Â Az/El rotor, yet provides 21.7dB gain in the L-band, and 27.7 dB gain in the S-band.Â
This US Military Experimental Flying Platform from 1955 is like a flying Segway. I wonder how long it will be before we have a modern day version of this. With technology that is becoming common place because of devices like the AR Drone I think the time is close since the stabilization technology would be quite trivial these days.
George Graves built this Constant Current Dummy Load Project based on this blog post over at the EEVBlog. It was built from a single sided board which was designed using ExpressPCB. That software is very nice to draft something up fast and it allows for an easy screen grab to etch what you see quickly. Thanks for sending this in Jim. “The only change I really made was running
The prize this week is a non contact AC test pen. This pen can be used to test if AC voltage is present in a wire without needing to touch the bare conductor. This contest will run for one week (May 19 – 25, 2012). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not
