Make a flaming LED skull
Here's a modded version of the "HotHead" (aka Lunatic's Flaming Skull)" Scary Terry writes - "I use a 4" fan mounted near the ground and PVC pipe to direct the air into the Bucky skull. The air flow from the 4" fan is superior to that of the 3" fan. Additionally, instead of using incandescent lamps, I installed super bright leds and they work fine." [via] - Link.

Updated: Taxidermy, rats, LEDs - and more...
Here's an update from us at MAKE - pt
"We took down the photograph accompanying this blog entry. I agree that the image is startling, to say the least, and I understand why some people would be offended. Taxidermy is an ancient craft but contemporary concerns about using animals to make things are worthy of discussion. As someone who eats meat, wears leather, and uses rat traps to kill rats in my attic, I'm in no position to point my finger at anyone practicing taxidermy. We've kept the comments section open for this entry, and I encourage people to continue the conversation. I know this topic elicits strong emotions in some people, but please keep the comments civil and constructive. -- Mark Frauenfelder editor-in-chief of MAKE

DIY Circuit - 1-Channel Light Organ for 12V Bulbs
Here's a circuit for making your own flashing color party lights for Halloween (also called a color organ), you can pick up all the parts at RadioShack, assuming your local RadioShack is one of the ones that still has electronic parts... - "The following pictoral diagram illustrates how to wire the elements of a "direct connect" color organ, which uses 12 volt bulbs. Critical parts are listed as Radio-Shack part numbers. The power transformer will be the most expensive item (max. $10). Since this color organ uses half wave rectified voltage, a 25 volt transformer is used. A choice of power transformer is given since the "1366" has a capacity of 1.0 amp (at 12 volts), while the "1512" has a capacity of about 4.0 amps. This device is connected directly to any 8-ohm source of sound, such as the speaker output jack of any sound system." [via] - Link.

HOW TO - Make a LED Dot-Matrix display
Pinski1 has a great Instructable in the MAKE group on building a LED display... - "This is a simple HOW-TO make your own personalised LED Dot-Matrix display. I will be adding the complete program with an explaination to light the LEDs with. It's also rather hackable, you can change it to suit yourself.
I decieded to make my own dot matrix display because they look cool, and none can be found in blue, which is the best colour, so I decided, may as well make it myself." - Link.

Altoids tin remote control

HOW TO - Build your own "True Random Number Generator"
On Wedsday night I attended dorkbot NYC (people doing strange things with electricity) and had a chance to meet Rob Seward who made a device that may or may not detect "consciousness fields"... the device is basically a random number generator and Rob has released the how-to online... - "This generator uses avalanche noise, and is based on a design by Will Ware. Herein are instructions as to how you can use a pic chip to analyze a noise source and output random data serially. I've included circuit diagrams as well as links to instructions for fabricating your own board.
There are two types of random numbers: true and pseudo. Pseudo random numbers are created by an algorithm. The problem with this is that if someone knows what algorithm you use, it is theoretically possible predict what numbers you will create. True random number generators create sequences that are impossible to predict. They use random physical phenomenon as their source or randomness. They are used for encryption and micro psychokinesis research." - Link.

Father of circuit bending Reed Ghazala's Flickr finds (photos)
MAKE pal Peter Kirn writes - "Over the past week Reed Ghazala, the innovator who's known as the father of circuit bending, sent me two sets of resources from his new flickr account. First, you'll find lots of fantastic and imaginative art and designs, circuit-bent and otherwise, in his whole collection. Second, he has a DIY circuit design for replacing a now-discontinued resistance substitution box, a key component in making warped, circuit-bent creations. If you click through to comments, several of my readers have some ideas for some alternatives to his idea, as well. And, of course, Reed waxes poetic about the passing of a beloved electronics part!" [via] - Link.
The photo here is a musical carafe (really) that Reed built for Tom Waits!

Wireless doorbell hacking - Remote PC starting, lighting control, Halloween effects control...
Here's how to convert a wireless doorbell from HomeDepot to close a relay instead of chiming...This whole thing started from a MAKE forum discussion! "With the addition of one capacitor, one relay, and a small piece of wire we can convert an inexpensive wireless doorbell into a remotely controlled relay useful for a wide range of applications. These include remote PC starting, lighting control, Halloween effects control, or virtually anything that can be controlled by a pair of relay contacts." - Link.

DIY Electronic drums
Geekboxjockey shows how to make an electron drum set on the cheap... - "This is kind of a general overview, the basic concepts are fairly simple. I looked at a lot of info out there before building my own, and I just kind of planned it as I built, it just takes a little creativity. Sorry to not include any links, just google it, I couldn't find the specific pages I used, but there is a community of people out there who do this stuff.
So an electronic drum set can run you back $600-3000+, sometimes without a module, my main reason for doing this was to save money bigtime. For comparison the cost for me was around $150-200 for all parts, then the module, so a total of at most $370, which as you drummers know is even cheaper than entry level acoustic sets! The most expensive item was the electric drum module or heart of it all which I will get to later." - Link.

Antique bike light LED mod
Alan writes - "Rob M. from Michigan bought some parts from our store and was nice enough to share the resulting project with us. His son Will has an antique bike on display, it has an old acetylene light on it that hasn't produced any light for many years. A few well placed LED sure solved that problem. Rob documented the circuit that he designed and is available in the photos below. The end result looks great!" - Link.

Solar dress
Wow, this is a pretty intense "solar dress" from Studio 5050 - "Day-for-Night, an hommage to Paco Rabanne as well as a celebration of the beauty of electronics, is a modular, reconfigurable dress comprised of 444 white circuit boards (although the number changes as the dress can get longer or shorter). Each tile is designed in such a way as to accommodate a solar cell, a RGB LED, or a photocell, and jumper connectors (in the form of 0 Ohm resistors). A control board provides power, communicates with the tiles, and links to a computer via RF. The dress is completely modular both in terms of software and hardware.
A USB board provides virtual serial port to Windows, Macs and Linux while an on board microcontroller relays data to and from the dress via a 2.4 GHz RF link. This allows for programmability (and status monitoring) from the computer side in the form of simple commands and responses via the virtual serial port. Currently a Max program has been developed that provides a graphical user interface for programming the tiles, while a Flash and Java program are part of future developments." [via] - Link.
