Hard Drive Laser Show
Sensory House made a version of Hard Drive Oscilloscope that was build a few years ago. The effects of the Sensory House version is great, the effects are nice and big! Thanks for listing us as your resource. 🙂
DIY Hacks
DIY Gas Hydroxyl – Hydrogen Supplemented Fuel
We are all trying to save some money these days when jobs are scarce and gas prices are high. 9w2bsr has built a custom PWM system to control the Hydrogen Generator, it attempts to maintain a constant current to the system. The Gas Hydroxyl system has been installed into a 3 year old Perodua MyVi and should increase its gas millage. I look forward to seeing what the results
Flip Clock Wrist Watch
I remember growing up with a flip clock on the bed side table. It was similar to the one pictured above except that it was encased in a stylish simulated wood-grained plastic box. Jeri from Fat Man and Circuit Girl took the flip mechanism and hacked it into a wrist watch. Now that is a time piece that any true geek can love! Via: Adafruit
iPhone Controlled R2D2 Robot
This R2D2 robot is a work in progress but in the end the creator will have it working 100% with his iPhone. The first steps video shows the robot under control of a standard remote but that is just a temporary control method. Have a look here for some of the iPhone interface information. We will have to keep our eye on the progress and report back when it
Acoustic Gesture Recognition
This Acoustic Gesture Recognition by Gary Halajian and John Wang from the Cornell University Designing with Microcontrollers course reminds me of the Object Scratching Input Device that Chris Harrison made (I later read the references and see that sure enough they reference the Object Scratching Input Device Project). "Our project utilizes a microphone placed in a stethoscope to recognize various gestures when a fingernail is dragged over a surface.
3D Laser Scanner
Cornell University has just completed their ECE 4760 Designing with Microcontrollers Final Projects. There are lots of great projects, this 3D Laser Scanner by Ryan Dunn and Dale Taylor looks to be a flexible scanning system. Code and schematics are provided so that you can learn from their project. "Our project implements the hardware necessary for a laser triangulation 3D scanner as well as a PC user interface for
DIY Subwoofer Project Build
This DIY Subwoofer Project Build shows that it is truly possible to make a sub that looks (and probably performs) better than lots of the stuff you would find in your local electronics shop. The use of leather and high gloss plastic panels really add to the high end finished look of the speaker. "The box itself will be built of MDF board. I chose MDF because I can
