Octopart embeddable parts list widget
Octopart just released this: the ability to embed a parts list right into your webpage without writing any code! Just create your list in Octopart and click "publish." Amazing; I'm going to go back and add this to all my projects. - Link.

Cassius punching bag
Fluidforms writes:
The Cassius Punching Bag contains a matrix of 9x7 force sensors that measure the force exerted by a blow to the punching bag. The sensors are plugged into an Arduino board that sends the values over USB to a computer using the MIDI protocol. The computer is running a Processing sketch that receives the MIDI packets and writes the current state of the sensors to a folder in a "|" separated format. An OpenGL render then reads these text files and graphically represents the current state of the punches to the bag since the last reset.Arduino punching bag with homemade sensors including video, code, and schematic - Link.
(Thanks, Byron!)

Killer-cool LED hat
As Hacked Gadgets says, you probably won't have time to create this amazing LED hat for this Halloween, but if you start soldering now, you might have it done for next Halloween, or if you hurry, next Mardi Gras. The results look worth the effort.

Suspended computer
The Sky Puter is essentially a computer without a case, while all components are suspended from the ceiling with a combination of coat hangers, cat5, and cat3 cable. Your airflow doesn't really get any better than this. To me it looks like a still frame of a computer exploding. - [via] Link.

The Drum buddy
Liane writes -
Just wanted to give you a heads-up if you don't already know... My favorite contemporary musical invention is going back into production! Mr. Quintron will be making ten more Drum Buddies after Laurie Anderson herself placed an order for one. The Drum Buddy is a unique percussion synthesizer made with oscillators, photoresistors, a light, a motor and a perforated number 10 can. Most of the Drum Buddies to be are already spoken for, but a few will be available for sale on eBay and Fresh Kills in Williamsburg.The Drum buddy - Link.

Electronic breadboard templates
Philip writes -
Actual-size Electronic Breadboard templates in SVG and other formats. A while ago I was wanting to document some breadboard circuits I was working on and went looking for an SVG-format electronic breadboard template I could use with Inkscape. The only file I found didn't seem to be actual size so I created my own. I've just uploaded a variation of my original design that also includes connectors from the Arduino Diecimila alongside the breadboard. When printed at actual size the dimensions and layout of the holes on this template should be able to accept actual component leads. The template files are in the Public Domain. The files are available in SVG, PDF and PNG format and you can either use an editor like Inkscape to layout your designs or print them out and draw on top. (Because they're actual size you could lay out the actual components on them too.)Electronic breadboard templates - Link.

HOW TO - Build an electric organ
Popular Science 1933 -
WITH its deep, mellow notes, the electric organ is fast gaining the musical limelight. As a rule, these instruments are large and costly. Yet, for the price of a new hat, you can build a duplicate of a small organ that was featured in a recent coast-to-coast radio broadcast.HOW TO - Build an electric organ - Link.Complete, the original instrument cost its designer, Elmore B. Lyford, a New York electrical engineer, a little more than five dollars. In spite of its low cost, its rich organ-like notes delighted the well-known radio pianists that fingered its keys and its simplicity interested the engineers that examined it. All you need to build the organ is nine 50,000-ohm variable resistances, a .003 microfarad condenser, some brass, a type '74 voltage regulator tube, a socket, and a few feet of insulated connecting wire. For power, the organ uses three forty-five-volt B-batteries.

Dorkbot Sydney at Electrofringe Festival
Pia van Gelder of Dorkbot Sydney writes:
Dorkbot Sydney recently held a two day electronics workshop in Newcastle at a festival called Electrofringe. The workshop was designed by Aras Vaichas an engineer/artist/dorkbotter from Sydney. We posted an account of the festival including details of the two machines we all made (the Nibbler and the Brainlet). In the post, I have also linked to PDFs of the schematics and handouts which have detailed instructions on how to put them together and descriptions of each component, in case people want to have a go, or just get more details. There are also links to videos of both machines, in development and finished, on YouTube.

Our speakers will be:- Lori Hepner: Lori is an interdisciplinary artist whose work focuses on aspects of coding through spoken and computer language in digital culture. Ambiguous visual representations of binary code are used in the Code Words body of work to create large-scale digital print installations and are performed in the Unworkings of a Binary System body of work. Ms. Hepner has been working through ideas of translation of code through performance, video, and photography since earning her M.F.A in Digital Media at the Rhode Island School of Design in 2005. Ms. Hepner currently lives and works in Pittsburgh, PA where she holds the position of Assistant Professor of Integrative Arts at Penn State Greater Allegheny
- Gabe Johnson: Gabe is a graduate student in the Computational Design program at Carnegie Mellon. He will be demonstrating FlatCAD, a design environment for rapid prototyping using machines such as laser cutters or 3D printers.
dorkbot pittsburgh meets upstairs at Brillobox, the event is open to the general public, non-smoking, and admission is free. See the website for full details and directions.
If you'd like to speak at dorkbot, if you know someone you'd like to see speak, or if there's a topic you'd like to learn more about, please let us know.

Lightning globe
This Instructable, involving high-voltage electricity, shows how to create a "lightning globe." Probably not a good idea for most people to mess with, but the results sure look cool.
This globe was done by the same guy who make a lethal electric fence from a computer monitor.
