PIC based countdown timer makes you early
This PIC based countdown timer was used to control lighting for the Ultra-Violet exposure of photosensitive PCB material, although it would come in handy for many other applications, such as cooking, or even exercising. It also includes an audible alarm when the counter finishes and relays control to turn on or off the lights.

Peggy 2.0 released
Our pals over at Evil Mad Scientist Laboratories have released version 2.0 of their awesome Peggy LED pegboard display kit. I had the pleasure of seeing this thing in action at last week's Maker Faire. I want.
...Peggy 2.0 still does the same darn thing: it provides efficient power to a 25 x 25 array of LED locations. Peggy is designed to takes some of the sting, complexity, and mess out of playing with LEDs. It's a versatile and powerful light-emitting pegboard that lets you efficiently drive hundreds of LEDs in whatever configuration you like, without so much as calculating a single load resistor. You can install anywhere from one to 625 LEDs, and Peggy will light them up for you ... The biggest change is that the Peggy 2.0 hardware now supports simple animation capability with individually addressable LED locations. Besides the microcontroller, there are now four support chips that help to drive the rows and columns of the display. Now, we're not talking live video feeds or long movies here (speed and memory considerations will spoil that party), but you might be surprised how much you can do with a little AVR microcontroller.

TouchShield & battery pack for Arduino
Matt (liquidware) writes -
I don't know if you've seen these yet, but I put up a couple of Arduino projects I've been working on, like a lithium battery pack, an "extender shield," and a TouchShield OLED for the Arduino. I brought these over to the NY Hacklab and the Make and tech meets a few weeks back. You might also like this video I made yesterday (below) of all the Arduino shields I have, stacked on top of each other.

Change a LED via the web
Here is an example of how to make a cool Internet application using the XPort shield I recently released. This is very simple, but its a good example of getting and outputting data. Basically the Arduino serves up a webpage with a bunch of nice javascript code that allows you to select a color. It also displays a "current color" (in this case a light green).
When you click "Submit" on the page, another request is made to the XPort/Arduino, this time with a GET command ?color=#xxxxxx with the color information. The Arduino looks for this command, parses the color requested and calls analogWrite() on the three LEDs to change them into that color.

All terrain Roomba/iRobot
Byron Lahey and other researchers at Arizona State University are working on this all terrain iRobot modification. He writes:
Robot Create robots are easily programmable and expandable in their functionality, but can only travel on a very limited varieties of terrain (carpet, hard flat floors and other typical interior domestic surfaces). As part of the Arts, Media and Engineering program we are working on systems related to the Mars exploration rovers. To teach about these systems and allow students to test and explore terrain navigation and mapping with robots, we needed robots with expanded terrain navigation capabilities. This video demonstrates an early prototype modification of the iRobot, comparing the performance of a modified and unmodified robot traveling on a rocky surface.
This video first shows how epicly the standard iRobot Create fails on a non-flat surface, then shows how his mods make it work better. Here are some photos of the modifications.

Build an ambient LED
Dave over @ PopSci shows you how to build an ambient LED project using an Arduino...
Ambient technology is the current rage for presenting information in a unobtrusive and, sometimes, sublime manner. Information suited for an ambient format ranges from complex number-laden data streams to simple one- or two-digit numbers. The idea here is that you can glean the same information by simply looking at the color of a cube, rather than consulting a sensor's text output.While this project doesn’t directly take advantage of ambient technology, it does show you a great method for generating a simple color-changing LED that can be integrated into any number of projects. By combining the open-source Arduino microcontroller circuit board with a “smart” LED called BlinkM, you can build a simple mood cube that randomly generates a spectrum of sumptuous colors.
By pairing a sensor with this Arduino-based mood cube to input data, you can create a more ambient-like experience.

PCB business cards
Evil Mad Scientist Laboratories made these ATmegaxx8 breakout boards that double as business cards. Windell writes:
Our design goals for this project were (1) to make a printed circuit board version of the minimalist target board for the ATmega168, encompassing a place for the chip and a connection to the 6-pin ISP header, (2) to make a minimal and inexpensive circuit board platform that you could use to deploy a single AVR somewhere with without much fuss, (3) to encompass the capacity of a breakout board, giving extra holes to tap into each pin of the AVR and provide labels for every pin, (4) to fit in some small amount of flexible prototyping space, (5) to make it all fit into a neat business-card form factor, and (6) to release it as an open-source project.
Brilliant, and I can't wait to trade business cards with them! - Link.

Open source hardware @ Etech (PDF)
Here are the slides in PDF format from the talk "Open source hardware" - this year there was a lot of hardware folks at Etech!
Open Source Hardware
Phillip Torrone (Maker Media), Limor Fried (Adafruit Industries)Open source hardware is a term slowly working its way into many new projects and efforts, but what is it? There are a few definitions, some of which come from "open source software," which is usually considered software's "source code under a license (or arrangement such as the public domain) that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form." So how does this translate to hardware?
This session will focus on electronic hardware, the layers they can be divided into, different document types, licensing concerns, and a show-and-tell of hardware.

New LilyPad Arduino programmer from Sparkfun
Sparkfun writes:
This is a USB to UART board that allows easy reprogramming of the LilyPad main board without the need for soldering. This board is based on the FT232RL IC from FTDI.
Features:
- Implements full v2.0 USB protocol
- Needs no external crystal
- Internal EEPROM for device ID and Product Description strings
- Royalty-Free Driver support for Windows, Linux, and Mac OS X
This is great for programming the LilyPad, as it requires no soldering or alterations to the Arduino Mini programmer (and has a flatter form factor), and it slots right onto the board! - Link.

“WiiChuck” Wii Nunchuck adapter available (for Arduino)
Todbot writes -
Want to hook up a Wii Nunchuck to an Arduino but don’t want to cut up the cord on your Nunchuck? Yeah me too. So I made some of these... It’s a small PCB that adapts the Wii Nunchuck connector to standard 4-pin header. I call it the “wiichuck adapter”. It plugs directly into the Arduino, no wiring necessary. You can get one too for $3.“WiiChuck” Wii Nunchuck adapter available (for Arduino) - Link.One of the coolest things about the Wii (to me) is that the expansion port on the bottom of the Wii remote is an I2C serial connection. This means that anything that plugs into that port can work with microcontrollers like the Arduino. Of the available peripherals, the Wii Nunchuck is one of the best. It contains a 3-axis accelerometer, a 2-axis joystick, and two buttons. Hooking up a Wii Nunchuck to Arduino is easy and I’ve have class notes describing how to do it. But cutting off the connector of the Nunchuck to get at the wires is a little drastic.
This “wiichuck adapter” let’s you play with the Wii Nunchuck and other Wii remote peripherals without needing you to cut cables. Just plug it into the Wii Nunchuck, then into the Arduino.

High-tech tinkerers on the rise - open source hardware
The Boston Globe turns on and tunes in to open source hardware (with MAKE mention + our Brian J!) -
For years, hackers and garage hobbyists have pried the covers off their gadgets, cobbled together computers out of components, or built other electronics from scratch. But today, even people who can't tell a resistor from a capacitor are finding new opportunities to tinker as the do-it-yourself spirit of the Web branches into the physical world.High-tech tinkerers on the rise - Link.

HOW TO - Make "Joy Slippers" - draw with your feet
Plusea shows you how to make slipper that you can "draw with" -
This Instructable will show you how to make a pair of cozy slippers that are designed with two analog inputs each that sense the pressure being weighted from the body on either the toe-ball or the heal of the foot.HOW TO - Make "Joy Slippers" - Link.Later steps in this Instructable will show you how to feed this analog input into your laptop via an Arduino physical computing platform. There are many things that you can do with this input, and I hope to bring out a few interesting applications in the next weeks. This Instructable features a simple drawing application that allows the wearer to control the direction of a line being drawn in real-time and thus draw, using the weight on their feet, in a very simple etch-a-sketch fashion.

openFrameworks workshop in London
Rock stars Theo Watson and Zach Lieberman will be running a Tinker.it workshop on their platform openFrameworks:
This is the first ever UK workshop on openFrameworks, a cross-platform C++ library for creative coding, and an opportunity to experiment with building new systems for interaction that move away from the screen and into physical space. This workshop is designed for artists, designers and hackers alike. On the first day, the workshop will offer a cohesive introduction to the library, as well as cover the fundamentals of computer vision, signal processing and interfacing with physical devices, via connection to Arduino. On the second day, participants will work to code creative and expressive prototypes based on these approaches.
If you're going to be in the UK on the 1st and 2nd of March, I'd highly recommend this. - [via] Link.

"Peggy," - A Light emitting pegboard display
Evil Mad Scientist Laboratories have released "Peggy" this is a great open source hardware project for LED art makers! -
With all the cool things that you can do with LEDs today, there is still one thing that's lacking: simplicity. If you want to run a bunch of LEDs at a time, you usually end up spending a fair bit of time worrying about series and parallel combinations, matching brightness, and picking load resistors. Or, if you're a beginner, maybe you only get one third of the way through the previous sentence-- wondering if you're already in over your head.Evil Mad Scientist Laboratories - "Peggy," - A Light emitting pegboard display Link.Suppose that you want to make a big LED display for your window or wall: maybe it's your logo, a symbol, your favorite 8-bit character, or maybe even a sign that spells out words like "OPEN" or "ON AIR." How do you go about it? The usual DIY solution involves drilling holes in a panel to fit your LEDs, then spending a heck of a lot of time wiring everything up-- ending up with one resistor per LED (and a three-dimensional mess if you happen to look at the back side of the panel). And, if you do everything in the most obvious ways, it can even end up consuming a surprising amount of power.
While I have certainly spent my share of time constructing things with the aforementioned technique, at some point it becomes clear that there has to be a better way. In this day and age, shouldn't LEDs be about as difficult to play with as, say, a Lite Bright? Today we are releasing a new open-source hardware and software design that takes some of the sting, complexity, and mess out of playing with LEDs. It's a versatile and powerful light-emitting pegboard that lets you efficiently drive hundreds of LEDs in whatever configuration you like, without so much as calculating a single load resistor.

HTML as sound
Ever wondered how HTML and image data would sound as beat samples?
Bill writes:
I've written a Firefox addon that makes it possible for a monome or arduino to interact with your browser. The url below is a video of me "playing" the raw data in the NYTimes homepage using a monome 40h. The project is called Lily and its a Max/PD style patching language that hooks into the browser and allows you to build multi-media projects (including physical controllers) on top of Firefox.
Each link highlighted actually makes for a nice percussive sound. This makes sense given that many percussive voices are synthesized using noise generators - and web data sounds similarly random to our ears. Awesome project, thanks Bill!
