In the latest issue of the Japanese RC Magazine I discovered a custom device developed to provide to radio controlled electric cars a sound similar to the gas engines roar. The system has been created by a reader of the magazine and looks like a gas exhaust. The sound is created trough a small compressor and not by a simple chip + speaker system like seems in some RC toys…Fake gas roar: is this the future for real electric cars in 20 years?!

I’m on a roll this week (pun intended!). After the tipi last Saturday, last night I used some canvas and sail thread from other projects to make a tool roll to carry with me on my old mountain bike (which I converted to a single speed, inspired by your weekend podcast of a few months ago).

Mark McNamara: Large Interactive Musical Toys
I have been very lucky during the first half of this year to be involved
in creating two large-scale musical toys that invited and relied upon
public interaction. The HAN project asked TUFTS students to acoustically
map their environment. We then created an interactive toy to access that
database of recordings. David Byrne’s Playing the Building turned a
landmarked building in lower Manhattan into a large musical instrument
that he then invited the public to play.

The ‘Bee’ is a mobile communication system developed by the Division of
Communication at UNICEF that allows for communication, connectivity and
data access in field conditions where such technologies are often
difficult or impossible to use. Included in the first prototypes are
webcams, radio transmitters and ultra-low-power computers. These
components are run with open-source software designed to support the
efforts of field workers and partners, and to be locally adapted for
ongoing use. At dorkbot, we’ll explain the design and technical
development of the Bee, as well as future use-cases and implementations.
We’ll also bring along our latest prototype.

New York based artist, interaction designer and Eyebeam fellow Ayah Bdeir will be talking about some of her experiments in putting technology where it doesn’t typically belong (or does but doesn’t typically exist) – from kitschy underwear to design furniture to electro-phobic art supply stores.

Interesting “GPS-A-Sketch kit” @ The Hacktory… Wil writes -
The idea behind the GPS-A-Sketch was to create an open shareable design that many users could use as the foundation for a modular, user-programmable, portable, GPS receiver. As the technology comes down in price (A Garmin eTrex of slightly lower specs can currently be had for $130), this technology should begin to be used for alternative uses (other than getting directions to the Walmart).
Potential uses could be in entertainment (locative games), art, r/c robotics, tracking and hopefully some things I haven’t even thought of.
The device should be easy to program (with user designed modular libraries), and allow for modular hardware addition, such as WiFi, accelerometers, sensors and interface components. I’ve chosen the Arduino based RBBB from modern devices as the initial processor, because of the vast resources and ease of use associated to the Arduino microcontroller platform, and the tiny form factor of the RBBB.
For now, the cost of a unit comes in at about $130 with the addition of an FTDI cable and shipping, bringing the total closer to $160 on a per/unit basis. Obviously there will eventually be ways to get this cost down below $100, including a single circuit board, and some shared bulk ordering on components.
Huh, here’s a homemade 30 watt laser, not too many details but the Australian maker seems to be answering questions in the comments of the video, baccus61 writes-
My 30 watt ULS powered Laser table with 54x30x9 dimensions. Still a few things to add like a rotary attachment and a martensitic stainless steel top.

Core77 has a nice writeup about the new exhibition at the MAD Museum:
Second Lives: Remixing the Ordinary will be the inaugural exhibition at the Museum of Arts & Design when it opens to the public today at it’s new home, 2 Columbus Circle. The exhibition features work by 50 international established and emerging artists from all five continents who create objects and installations comprised of ordinary and everyday manufactured articles, most originally made for another functional purpose. Paul Villinskii, an American, creates beautiful butterflies out of his old record collection, producing a “soundtrack” of his life. English artist Susie MacMurray used yellow rubber washing gloves, turned them inside out and stitched onto a calico form to create an imposing out-sized dress. Other featured works are made from buttons, spools of thread, artificial hair, used high-heeled shoes, plastic spoons and forks, shopping bags, and 25-cent coins to mention only a few.

“Sound Wave” – A wave made from a pile of melted vinyl records
This circuit is a simple “lighthouse” style beacon that when powered on rotates light around 12 LEDs that are mounted on the circular PCB. The project uses a PIC12f683 using SourceBoost Technologies BoostC and OSRAM SIDELEDs as the lights. The link below explains how to build this as well as some of the problems its author came across although there’s a nice photo of the finished PCB design for those interested in using it.
After using all of those plastic bottles to sail across the Pacific Ocean (see above post), what better way to re-use them and their discarded caps than to make a lamp. The “Captivate” lamp by Lucy Norman is constructed of the bottles as well as their caps which can be intechanged to change the color the lamp emits. Pretty cool idea and nice use of the bottles for ambient lighting.
