Congratulation to the last winner. The prize this week is a 2.5″ PATA hard disk enclosure that allows you to take your data on the road. Just slide in a drive (not included) and plug into your USB port. This contest will run for this weekend only (September 22 – 23, 2007) . Ending time is based on central standard time. To enter, identify the item pictured above and give
Pyrofer has made a new PIC project, this time a bit of extra processing power was needed so the PIC chip was overclocked. The resulting Stereoscopic 3D is fascinating. “I needed a viewer that would present each image to each eye independently while maintaining focus and positioning. For this I took my previously dismantled 3D tomytronic game. Each LCD (128×160×8) as sat in the viewfinder aligned so each eye
Thanks to Paul Gittings for leaving a comment with this cool FPGA digital oscilloscope that Jean P. Nicolle from FPGA 4 Fun developed. “Let’s build a simple digital oscilloscope. * Single channel 100MHz/100MSPS (100 mega-samples-per-second) * RS-232 based (we’ll look into USB too) * Inexpensive! A simple digital oscilloscope recipe Using parts from KNJN.com, here are the basic items of our recipe (prices accurate as of this writing, Feb 2007).
Not as creepy as it sounds ROACH is simply an acronym for RObotic Automation Control Hierarchy. “Here you can see the white camera, and conical lense hood of the IR pyroelectric sensor on the pan/tilt head. The pan (stepper)/tilt (servo) mechanism is partially obscured. You can see the main power batteries arranged in a triangular configuration. The SRAM backup power is supplied by 4×1.2VDC NiCd batteries located in the center
This interesting mirror by Daniel Rozin is quite neat. It would be fun to build one of these on a smaller scale using some cheap servos. I can’t imagine the cost of this large unit with over 700 motors! “Rozin’s Weave Mirror assembles 768 motorized and laminated C-shaped prints along the surface of a picture plane that texturally mimics a homespun basket. A seemingly organic smoky portrait comes in
Chris Anderson was lucky enough to visit the Google campus and took some arial pictures with a digital camera mounted to an RC plane. To enhance the picture taking capability of the rig he decided to make a gyro stabilized system to mount the camera onto. Video after the jump. “The secret ingredient is an off-the-shelf “heading hold” gyro made for a R/C helicopter. These can be found for as
Our friend David from Volunteer Lab Rat has built a tesla coil from a 15,000 Volt neon transformer. Make sure you check out his videos on the project page. “An AC power supply, here a neon sign transformer creates 15kV. The transformer will charge the capacitors. As they charge up, the voltage across the spark gap will rise. Eventually the potential across the spark gap will be large enough so
