Gadget Freak Elves' Workshop Edition @ Design News - Holiday electronics projects
Our electronics pals @ Design News just sent us this massive holiday project bonanza, check it out, they're also running a contest.
..The neighborhood this holiday by turning your house into a real Elves' Workshop and building the seasonally appropriate electronic gadgets listed below! Each project includes a parts list and complete build instructions to guarantee this December is one of endless fun for you and your family and friends.
- Holidazzle Lights Flasher CircuitAdd some real flash to your holidays this year. This circuit allows you to create exciting flash patterns and sequences for the many light strings we know you'll be planning to put up this year - Link.
- Simple tester checks Christmas-tree lightsWhy is it that you always test 48 bulbs before you find the bad one in a 50-light string? This simple circuit allows you to divide and conquer, greatly reducing the time it takes to find the bad bulb - Link.
- Flickering LED CircuitReproduce that warm glow this winter with this electronic flame flicker device that can be customized to achieve the realistic effect of a flicker candle, oil lamp, or campfire. Your local fire department will be buying your presents - Link.
- Automatic Tree Watering SystemSleep peacefully this holiday season knowing that your tree won't go up in flames like so much kindling. This electronic watering system includes a 1-gal reservoir and dc-powered pump assembly to ensure your tree stays moist and fresh - Link.
- Blinking LED Holiday StickpinBe the center of attention at your next holiday party with this nifty holiday stickpin that features a low-voltage blinking LED. No lampshades required for assembly - Link.
- Simple scheme saves string-light situationAs you enter the holiday season with strings of ac-line-powered lights hanging everywhere, do you ever wonder how bulb vendors overcame the frustrating problem of having an entire string go dark when just one of the series-wired bulbs failed? - Link.
- Nonfailing light-bulb-string storyThe preceding article on how series-wired Christmas lights self-heal prompted some interesting reader responses suggesting alternative ways that a failing bulb does not cause an entire string of bulbs to fail. Apparently, some light strings use another mechanism, and we have some hands-on evidence to confirm this fact. This approach involves no software, no microprocessors, no logic gates, no nanosecond timing --just some passive light bulbs and clever materials engineering - Link.

WOSP input device (Way Old-School programmer)
MAKE Flickr photo pool member rRbohn uses a bunch of light switches to program LEDs -
"Bank of 8 switches for the Way Old-School Programmer... This is the output section for my Way Old-School Programmer computer. One of my red LED's was bad, so I took it off the board and will have to buy two to complete that part. This will initially hook up to the Arduino board, eventually I plan to at a Mega8 AVR right on this board. " - Photos & more.

Single tube Nixie clock
Ohararp has a single Nixie tube project that is freaking great -
"Christmas is around the corner and I am still working on my nixie clock and have everything all set as far as powering the clock from the usb port and the high voltage conversion. I am playing around with crystals and code to get everything all dialed in. The final design will be mounted on a 2" circular diameter pcb. This will allow the clock to be easily mounted inside a 2.25" round acrylic tube. Total price should be around $30 for the clock. One of the really neat things about this clock is the allowance for a battery backup using the LIPO BACKPACK II. With the latest iteration of the backpack and the 1A current capability you can now power the clock on its own for over 20 hrs!" - Link.
The SD GPS logger on the site is really nice too.

Arduino-serial: C code to talk to Arduino
Todbot writes -
"The Arduino's USB port is actually a serial port in disguise. To your computer it appears as a 'virtual' serial port. This is good news if you want to write custom code on your computer to talk with the Arduino, as talking to serial ports is a well-solved problem. (Unfortunately, so well-solved that there's many ways of solving it.)
On the Arduino forum there's been a few requests for some example C code of how to talk to Arduino. The nice thing about standard POSIX C code is that it works on every computer (Mac/Linux/PC) and doesn't require any extra libraries (like what Java and Python need). The bad thing about C is that it can be pretty incomprehensible.
Here is arduino-serial.c, a command-line C program that shows how to send data to and receive data from an Arduino board. It attempts to be as simple as possible while being complete enough in the port configuration to let you send and receive arbitrary binary data, not just ASCII. It's not a great example of C coding, but from it you should be able to glean enough tricks to write your own stuff." - Link.
This is really interesting for a few dozen of you, so have at it.

Acceleromouse (DIY Nintendo Wii-like remote for PC's)
Macaba writes -
"Ages ago, I was toying with the idea of making a DIY in-air PC mouse, and had designed it in my mind. A few days ago I saw the Wii-remote bluetooth PC controller hack and thought that it was good time to throw together my own version.
As shown on http://wiihacks.blogspot.com/ the Wii remote has been utilized as a bluetooth remote for the PC/Laptop. My version isn't as good, as it works over PS/2, and is wired (for now!). But I always find the enjoyment is in developing your OWN firmware for devices as long as it works (messing for 2 days and still not getting it working is the ultimate frustration, luckily didn't happen).

Two makers
One cause
Fünde Razor
Here are some Guitar Hero controller guts transplanted into real guitars... part of the Funde Razor charity event to be held in Brooklyn on Wednesday 12/6. All proceeds from the raffle and competitions go directly, 100%, no overhead to the kids of The Children's Hospital of Montefiore in the Bronx, via the Child's Play Charity.
Jmillerid writes - "I got in touch with Joel as a result of the Makezine blog entry about the Funde Razor event tomorrow in Brooklyn, and created two Guitar Hero controllers for the event... I just wanted to share with you the results which I also added to the Make Flickr pool." - Link.
Chuck writes - "I just posted an exhausting how-to on building a custom wireless GH2 controller - the one we built for the Funde Razor event tomorrow night. There's over 110 pix and lots of description. This should be the Bible (at least the Old Testament) for anyone wanting to try this at home. - Link.

Autonomous stabilization system for a helicopter
Idan Beck & Rohit Gupta built an autonomous helicopter for their final project (schematics/source included)...
"The purpose of this project was the design of a fully autonomous stabilization system intended for systems capable of intelligent programming and navigation. This means that the design focuses mainly on the control feedback systems that control the helicopter's motors that then provide lift to increase and decrease altitude, and produce a tilt about the helicopter's central vertical axis which would be used for stabilization and potentially lateral motion. We chose this project because it was an ambitious projected aimed to challenge us as well as provide a level of sophistication that would allow this project to be applicable not only as a semester project but to potentially be used in future projects."

HOW TO - Saltwater etch process
Neelandan writes -
"This is a one-off process to produce one printed circuit board by removing unwanted copper by electrolysis in a saltwater solution.
I shall illustrate the process by etching and building a board for 18-pin PIC (for the PC16F54, but any 18 pin PIC will fit in it) in the figure. It has to plug into my breadboard and accept the programming signals from my PIC programmer (just go to http://geocities.com/it2n/circuits.html and look at it).
To avoid battling with signal conflicts, the two programming pins shall not be brought to the breadboard. To play around with the clock frequency, the crystal shall be made pluggable. The Master clear signal will not be brought out.
These decisions mean a board with two .1" pitch connectors, one with 13 connections and the other with five connections, one pin spaced apart from the rest.
This is a tutorial intended for the absolute beginner, and almost every step shall be illustrated. I've even included a video of the etching process." - Link.

PIC based kitchen countdown timer
The most Mad-max kitchen timer I've seen today...
"It's a kitchen timer. Use it to time spaghetti, or maybe an egg. It uses two PICs, one acts as a keyboard encoder, the other drives the display and supports the timer functions. You key in the desired time and press '#'. It's accurate to 1/100th of a second, which can make all the difference I'm sure you'll agree." [via] - Link.

Simple serial RGB LED controller and driver
Pete writes -
"If you want to build your own multiple RGB LED display that you can control from either a PC or a dedicated controller then this project will let you do just that.
The project on this page came about when while I was developing a more complex intelligent driver. During that work I put together a simple Red/Green/Blue Pulse Width Modulation LED driver that has a serial interface. The RGB values to control the LED brightness are sent to the PWM driver over this serial interface. " [via] - Link.
