Lush Projects has an cool tape deck hack that allows for some neat sound mods. “First mod was to setup one deck to allow scratching. To do this I originally removed the pinch roller so that the tape could run free. Later on I realised I could modify the pause button to retract the pinch roller without actually pausing the player. The second mod was to make a tape delay
Have a look at this huge Seven Segment Display made by Turd, a Hacked Gadgets Forum member. Other than the ones made by the guys as Sparkfun this has got to be the largest one I have seen. Watch a video of it in action. “I made this for a test. It’s made from a picture frame, some foam from a camping mat, blue translucent film and a shopping bag
These are probably some of the most expensive clocks around. 🙂 I would love to have a Robot Arm Clock in my living room though. “The robot arm is probably the most mathematically complex robot you could ever build. As such, this tutorial cant tell you everything you need to know. Instead, I will take shortcuts and just talk about the bear minimum you need to know to build
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
