What the heck is this thing?
Kaden wants to know what the heck this thing is... He writes -
Mid afternoon yesterday I was laying out a cutting diagram for the third or fourth time,and caught myself writing dimensions down inside littletags. Clearly, I needed scrapyard therapy.So it was off to NorthStar. Where I found THIS (see attached) rolling around in the bottom of a tub of mystery metal.
It's brass with a maple handle; really nicely machined metal, and the handle is *properly* attached with set screws...none of that press fitting crapola here. The brass part is conical, tapering from a 3/4" widest dimension to a near-nasty point in 2 3/4". Most of the lacquer is still intact on the brass, and the fold out knife blade inset into the cone still has a pretty good edge.
Huh?
Yeah...fold out knife blade. 2 3/4" x 1/2", hinged on a rolled steel pin just up from the base of the cone. The blade nests almost flush into the cone, and swings out effortlessly, stopping but not locking perpendicular to the cone, with the edge pointng in the same direction as the cone. It's ,like a parallel universe mash up of a gardening tool and a switchblade. The guys at the yard were stumped by it, which is a rare event, and no one remembered when it came in, or from where. My pal Joey, who works seasonally on crab boats (as seen on the Discovery Network) was adamant that it had no maritime connections, but thought it would be pretty useful for patching nets. Me, I had it pegged as a weapon used in full-contact horticulture, but that could have just been lack of sleep talking.
Couldja put it to the Maker Massive and see if anyone knows what this thing is?
If someone can accurately identify it I'll send you a MAKE Pocket Ref.

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.Dorkbot-Syd at Electrofringe Festival 2007 - Link

Chris writes -Here are some pictures and plans of an homemade in-car camcorder mount. It fits very stiffness on the passenger's seat headrest allowing hands-free filming from the driver's viewpoint. To make your own that fits your car, you'll need approx. 2 feet of 3/4" aluminum or steel square tube, 2 u-bolts, 4 wing nuts for tool-free installation and an universal mounting screw (or a web cam swivel stand for lighter cameras). The total cost in material is below $15.00 USD. Drive responsibly !Homemade in-car camcorder mount - Link.

Learning Arduino, programming, electronics? Here's a MASSIVE tutorial on serial library and binary data with Arduinos - Ladyada is on a roll...
Ah, Arduino, I remember when you were just crawling around and blinking LEDs. Now you're ready to learn how to speak! In this lesson we'll learn how to use the Serial Library to communicate from the Arduino board back to the computer over the USB port. Then we'll learn how to manipulate numbers and data.Serial library and binary data - getting chatty with Arduino and crunching numbers (Lesson 4) - Link.For this lesson we won't be using the shield, so simply remove it (keeping the mood light LEDs on it you'd like). The shield doesn't contain any programs or data, This way we can examine the RX and TX LEDs which will help you with debugging

Arduino @ Adafruit... Arduino is a project from Ivrea University. A simple microcontoller board with an ATmega168, and a USB connection. Its great for learning and small projects - Link (starter pack!).
Arduino @ MAKE! Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino is open source! - Link.
Making Things Talk. THE ARDUINO BOOK!!! Programming microcontrollers used to require an expensive development environment costing thousands of dollars and requiring professional electrical engineering expertise. But recent innovations, such as open-source physical computing platforms with simple i/o boards and development environments, have given hobbyists, hackers and makers new options for homebrewing video games, robots, toys, and more.This book contains a series of projects that teach you what you need to know to get your creations talking to each other, connecting to the Web, and forming networks of smart devices. Whether you need to plug some sensors in your home to the Internet or create a device that can interact wirelessly with other creations, Making Things Talk shows you exactly what you need.
The projects in this book are powerful but inexpensive to build: the Arduino and Wiring microcontroller kits themselves cost around $40. The networking hardware covered here includes Ethernet, Wi-Fi, Zigbee, and Bluetooth, and can be had for $50 to $100. With a couple of microcontroller kits and the networking gadgets of your choice, you can make things and make them talk to each other! - Link.

MAKE Flickr photo pool member Rosendahl writes -I just finished this yesterday. Based on an original design that I built in college, this is an LED lightshow that plugs into any audio source. (I have it on top of our home entertainment system, so it shows whatever we're listening to or watching.)Black Box lightshow - Link.The display is divided vertically into left and right channels. It displays the top half of the waveform of each channel with their zero levels in the center. The two knobs control the amplitude and the sweep speed.
When set to the right speed, a strong bass note will show up as a floating red bubble. A note an octave up will be two bubbles. Notes inbetween will be a series of bubbles floating up or down the display. Of course, all the other frequencies are in there, too, so you get a much more complicated display, but the bass tends to be the most prominent. Dynamics from drums, etc. cause the width to pulse. It all ends up being quite hypnotic.
The box... well, it's just a black box I built with a plexiglass front. Suggestions for a sexier box are welcome!

Socratic electronics has a lot of downloadable worksheets if you're learning (or want to learn) electronics, they take a different approach than traditional teaching... -The purpose of this website is to provide both rationale and resources for research/discussion-based instruction to instructors everywhere. Central to the Socratic Electronics project is a large collection of questions and answers, intended as student assignments. By requiring students to research answers to these questions, then present their findings in class, students learn how to locate information, problem-solve, collaborate, and clearly articulate their thoughts while learning the basic subject matter. While the resources provided on this site are specifically designed for teaching electronics, the method itself is applicable to a wide variety of disciplines. I welcome constructive criticism, as well as participation in the development of this learning resource.Socratic electronics - Link.An important feature of these questions and answers is that they are configurable. They are organized in such a format as to be assembled into custom worksheets suitable for use in a variety of electronics classroom settings. Thus, you are not bound to using the compiled worksheets as they appear on this website. Rather, you may easily select which problems you wish to have on your own worksheet(s), and create them automatically by editing and executing a simple computer ``script'' file.

Brian @ Hackszine writes -NightLight wrote in with a request for a red overlay to "use your iphone in the dark but keep your night vision." I was reminded of the hacks about using red film in Astronomy Hacks: put it over your PDA or notebook computer, and you are all set. But to try it out, I needed to find an astronomy site that works well on the iPhone. Many online planetariums use Java to do their thing, but Your Sky is a great web site that does a couple of things simply and quite well: you can punch in your latitude and longitude, and you get a view of exactly what's above you at the moment. You can tap to zoom in, and you can pan around. Just what I needed. (To save a little time, figure out your latitude and longitude on your Mac, save a bookmark for your Your Sky page in Safari, and sync your bookmarks to your iPhone so you can get to the star chart quickly.)Use your iPhone as a stargazing companion - Link.
