From context clues, we can tell that [TVMiller] has been in and around NYC for some time now. He has observed a crucial weakness in the common metropolitan. Namely, they deafen themselves with earphones, leaving them senseless in a hostile environment.

To fix this problem, he came up with a simple hack, the metrophone. An ultrasonic sensor is hung from a backpack. The user’s noise making device of choice is plugged into one end, and the transducer into the other. When the metropolitan is approached from the rear by a stalking tiger or taxi cab, the metrophone will reduce the volume and allow the user to hear and respond to their impending doom. Augmentation successful.

The device itself consists of an off-the-shelf ultrasonic sensor, an Arduino, and a digital potentiometer. It all fits in a custom 3D printed enclosure and runs of two rechargeable coin cells. A simple bit of code scales the volume to the current distance being measured by the ultrasonic sensor once a threshold has been met.

In the video after the break, you can observe [TVMiller]’s recommended method for tranquilizing and equipping a metropolitan in its natural habitat without disturbing its patterns or stressing it unduly.

Arduino DUE, gShield and TinyG enhance desktop CNC performance

TinyG with ShapeOko

TinyG2 is a cross-platform ARM Port of the TinyG motion control system that runs on the Arduino Due. It can be used with the gShield to build a high performance 3 axis motion control system.

G2 has a number of advanced features, including

  • 6 axis motion control – XYXABC axes
  • Can control up to 6 motors (3 are on the gShield)
  • Jerk controlled acceleration planning – S curves using 3rd order motion planning
  • RESTful interface using JSON – talks directly to Javascript, Python and other languages over USB

During World Maker Faire in NYC we met Alden Hart. He is part of Synthetos where they built TinyG and the grblshield and experiment on other cool stuff for the hacker/maker community:

We chose the Due as the platform for the TinyG ARM port because it’s powerful enough to really run the application well, but it’s still simple and accessible so people can extend the application and experiment with new functionality.

You can learn more about TinyG on their open wiki maintained by Synthetos team, it serves as a user and programmer manual, and documents progress on the project: anyone can post wiki-type stuff.




Making noise with Arduino- Workshop at IDEO NYC

Dario Buzzini and I have been friends since we met at the Interaction Design Institute Ivrea several years ago. Ever since, we have worked together on interaction design projects for different clients. While visiting NYC for World Maker Faire last month, we organized a free open workshop for 25 participants at the IDEO NYC office (where Dario works)  focused on creating sounds and music.

Make Some Noise” was a short, one-day workshop about Arduino where we explored the topic of sound and it was aimed at complete beginners with no experience. To simplify the structure of the workshop we started with hands-on experiments composed by a quick set of exercises to enable the participants to understand the basics and, later on, to start exploring pitch, frequency, tone, and multiple effects—with quite curious results (see videos below)!



To make things even easier, we focused only on one type of output  showing how you can relate that output with several types of input, like different sensors. We started, as usual, blinking a LED and then learned how a speaker clicks the same way an LED blinks: if you do it fast enough you can make a sound, if you do it at a specific speed you can make a note, and if you look up at all the frequencies associated with all the notes you can make scales.

After some testing, students were able to create noises, sounds, control them through slide sensors, buttons, potentiometers. At the end, as a fun exercise we used a piece of open source software that one of the Arduino users put on the Arduino Playground, which turns the Arduino into an eight-oscillator synthesizer that can use any piece of metal as a sensor. We then connected eight soda cans with an Arduino and a speaker. It played them as if it was a church organ!

Design and technology have, once again, come together to redefine, shape, and explore new experiences through simple, approachable tools.
