Serial library and binary data - getting chatty with Arduino and crunching numbers (Lesson 4)
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

- Lesson 0 - Pre-flight check...Is your Arduino and computer ready? - Link.
- Lesson 1 - The "Hello World!" of electronics, a simple blinking light - Link.
- Lesson 2 - Sketches, variables, procedures and hacking code - Link.
- Lesson 3 - Breadboards, resistors and LEDs, schematics, and basic RGB color-mixing - Link.

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.

Black Box lightshow
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
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.

USB to serial project
Spikenzie writes -
The USB to Serial project is a break-out board for the CP2103 from Silicon Labs. I was looking for an inexpensive Serial Port solution for my Mac, that I could build into my projects without external adapters. I have the KeySpan USA-19HS, which works very well, but it is too expensive to build into projects and you must use a level shifter to safely use TTL or 3.3 volt signals. For projects where adapters are not convenient you can use the CP2103. With this break-out board, you have pins for all of the RS-232 signals, four GPIO pins and 5 volts, 3.3 volts and ground. I made it with the intention of testing designs on a bread-board, but it may also be incorporated into another design by simply plugging it in like a DIP.USB to serial - [via] Link.

LED lamp art
A French designer named Kei Yamamoto has created this uber LED lamp which is 20 times the size of a normal LED bulb. He writes:
Not only does the product show the beauty of the LED structure, but it also creates a special visual effect on the ceiling, 12 LED bulbs are refracted through the Acrylic glass lens to generate this pattern. Materials: Aluminum, Acrylic glass, LEDs.
This is a one-off piece o' art, but man, I'd buy a commercial lamp like this...

Piezoelectric concept backpack
Researchers at Michigan Technological University, Arizona State University and NanoSonic Inc. are working on harvesting the ambient energy of walking and carrying a backpack with polyvinylidene fluoride (PVDF), a nylon-like material with piezoelectric properties. This would be great for multi-day hiking, since you wouldn't have carry heavy batteries to keep your GPS or cellphone juiced! - [via] Link.

Make a Theremin - Weekend Projects PDFcast
I ordered a minimum theremin kit from Harrison Instruments and all the parts were very well marked and it went together easily. You will have to make your own antenna and put it in your own enclosure and I liked that because it gave me a chance to make my theremin unique and special. - PDF Link
There are a bunch of other kits you can buy, but this is the simplest one that I could find. Go check out a previous Make: post with lots of choices for kits. - Link
When you make your theremin, put it in an awesome enclosure and make sure to take photos and upload them to the Make: flickr pool!

Atari Punk console
Jason writes -
he Atari Punk Console is a simple electronic music circuit that you can easily put together in a weekend. The original concept was created by Forrest M. Mims III, writer of Getting Started in Electronics. At it's simplest it's just a 556 dual timer IC, a couple potentiometers, and a few capacitors and resistors. Hack together a slick enclosure, though, and you've got a beautiful little gizmo that pumps out sick square wave goodness.Atari Punk Console - weekend electronics project - Link.GetLoFi has a few good links to schematics, sample audio, and enclosure ideas. Forrest himself even checked in and commented that you can use things like photoresistors or other sensors in place of the potentiometers to have the audio output controlled by the device's environment.
