Authors: Dangerus Prototypes

The Tacit Project from Grathio Labs is developing a wrist mounted sonar assistive device for the visually impaired. The hardware includes Parallax Ping ultrasonic sensors mounted in the glove which send distance measurements to an Arduino. The Arduino then activates small hobby servos to vibrate in the glove to communicate the relative distance to objects.

You can find the schematic and source code for this developing project at the Grathio Labs website.

It’s hard to overestimate the awesomeness of seeing metal splash around like water.  Seeing Chicago Crucible transform small heaps of busted up iron into awesome art by using fire seemed to be a highlight for many.

The raw materials, from old radiators and such like, busted apart with sledgehammers, measured out with scientific precision.

These molds served as the final destination for the liquid iron.  For $20, you could buy one of the square forms (to the left in the image) and carve it up however you like, and they would pour it for you.  Observe the leftmost, already filled.

Ideo worked on the changing relationship we have towards music, adding a new, dynamic yet vintage approach:

The concept behind the C60 Redux is this: We’ve gone from handling vinyl, tapes and CD’s to clicking on MP3′s, losing tactility in the process and making a casualty of the mix tape. Is it possible to bring that back in a digital way? Bone, Johnson, and a group of IDEO designers endeavored to do so by creating a music player built with RFID readers and some Arduino Mini Pros, all housed in a record player case

Does the mix tape still exist in a  digital world?

Authors: embedded

Probably you’re already familiar with ChipKIT boards that are Arduino shield compatible also can be programmed using modified Arduino IDE. These boards are great resource for those who are looking for better performance and more features comparing to Arduino.

So here is a classic Pong game developed under ChipKIT Uno32 platform. It generates color VGA signal through resistor based digital to analog converter assembled on a breadbord. As Pong generally is two player game there are two potentiometers for control and two 7 segment LED indicators (for score) dedicated for each player.
