12V 15A power distribution box v1.0
Will writes -
"Ok, so here is the scenario: working with CCTV cameras a lot you find that most of your pro-sumer nightvision cameras run on 12VDC. Turns out that all the commercial solutions for distributing 12VDC are limited to 5 amps. Not a whole lot of juice when you are wanting to drive 16 cameras a 500+ milliamp.
After brainstorming on how to build a better system (and more stylish) I realized that a 400 watt PC power supply could kick 15 amps and keep trucking. That was the kind of power I was looking for, almost a full amp per camera if I needed it.
With that in mind, I chopped open a power supply I pulled out of a computer and I quickly came to realize this was going to be easier than I thought. Paying attention to where the yellow and black wires attached to the power supply's circuitry I began hacking at the wires, removing them all." Thanks Chrome Ghost - Link.

CRAFT milling
We posted up the big metal MAKEs and NickCarter just sent in his silver millings from the CRAFT contest -
"Just to toot my own horn (not as much fun as it sounds) I put up a Flickr set about making the craft: logo in sterling silver a while back.
The process of design is identical to Frank's, I used Rhino and Bobcad (cad and cam). Rather than casting for the bracelet I made a rolling mill die, and for the keyring I just milled it directly into the material.
I like those castings! " - Link & key ring.

Piklab: an open-source IDE for PIC and dsPIC development
Stokes writes -
"Microchip's line of PIC microcontrollers remain very popular with hobbyists, despite their development environment being more proprietary and Windows-centric than those of other microcontrollers. Enter Piklab: an open-source IDE for PIC and dsPIC development, leveraging a number of open-source tools and tying them together in a single environment.
Piklab is still in beta, but it shows a lot of promise." - Link.

HOW TO - Dimensional photography on the cheap
Phil writes -
"Dimensional (3D) photography is a simple process, at least in theory. You provide a separate image of the same scene for each eye, slightly out of phase. Of course to do it right, it takes a good amount of photographic skill, an understanding of the psychological and mathematical principles involved, and some fairly precision hardware.
But, in a true do-it-yourself fashion, you can get everything you need to create your own 3D photos for a modest investment. Here's how...
What you'll need is a pair of matched digital cameras, a few tools, some 1/8 inch aluminum abgle bracket, a few bolts, and some 3D authoring software. " Thanks Robert! - Link.

DIY $100 window seat
Shollen writes -
"I've recently been faced with a large, empty apartment, a budget, and about a week to make it feel like a home. Furnishing via Craig's List had always been my plan, but with two living rooms? Oh, also, by the way, we can't fit anything larger than the smallest loveseat up our stairwell. The one that did make it up here was the result of a 45 minute battle with geometry. The stairwell lost-and not without some wounds to show for it-but we weren't about to invite another couch to war. Didn't they have large pieces of furniture in the early 1900's? What gives?
Anyhow, my sister and I were pondering our large-empty-space, low-budget problems (and recognizing that there was no possibility of solving either problem with big cheap couches) while sitting in the window seat of a downtown Providence Starbucks. Now, wait...we can bring materials up the stairwell... 12 cinder blocks and 32 square feet of particle board later the project had started." Thanks Andrew! - Link.

Make: projects- Building the Perfect PC (review)
yyztech.ca reviewed our Make: projects book "Building the Perfect PC"
"As the tag-line on the cover says, "The perfect PC is the one you build yourself." and so this book aims to show the reader how building your own PC is the best way to get the PC you want. Since there are different "perfect" PCs for different tasks, the book shows the different trade-offs made while building everything from a budget PC to a server and a mini-PC.
At 400-odd pages, there is a lot of information contained in this book. The PCs you'll learn to build include: a basic home PC, home-office server, gaming PC, media centre PC, small form-factor and a budget PC." - Link (full review).

HOW TO - Remote controlled RGB LED mood light
5Volt writes -
"Control the colour of a powerful LED light beam with a remote control, store the colours and recall them at will.
With this thing I can control the colour of a bright light into many different colours using the three fundamentals colours : red green and blue. Adding them toghether with different intensity can yeld very great a range of colours from the visible spectrum.
Specifically my mood lamp can shift colours through 32 intensity values for each RGB colour giving 32*32*32 = 32768 different combinations of hue, intensity and brightness. It can also store 10 different combinations can be turned on or off, all of these through a TV remote control.
The intensity of each red, green and blue component is done via PWM so heat dissipation is kept to a minimum.
The circuit is simple and there are no pushbuttons as control is done entirely through the remote control. I use this circuit to light a flower vase. The flat case of the box I chose does a good job at balancing the vase. The pictures provide some ideas. One day I am possibly buying one of those glass cubes with LASER created 3D shapes inside to go with the lamp. For now glass vases are just fine." - Link.

HOW TO - Flash MIDI
Fred sent in a great Flash (Macromedia/Adobe that is) to MIDI control project --
"From 1734 when Louis-Bertrand Castel, a Jesuit monk, created the Clavecin Oculaire, a 'color harpsichord,' until today, artists have created instruments for performing color compositions. In the late 19th century, Alexander Rimington created the first 'color organ' for use in public performance. In the 1920s and 30s, Thomas Wilfred traveled the United States and Europe performing 'lumia' recitals with his 'clavilux.' In this tradition, I developed a computer system that allowed for the performance of user-controlled Flash animation.
The user interface is a Mad Catz Playstation 2 game controller and the UC-33e Evolution MIDI controller by m-Audio. The computer is an Apple iMac G5 with 1.8 GHz processor and 1.5 GB of RAM. The MIDI and game controller signal data is sent to Flash (.swf) files being played through the stand-alone Flash Player, utilizing ActionScript 2.0 code in Flash 8 via MAX/MSP 4.6 software. An LCD projector and sound system are the final destination outputs. " - Link.

MiniPov kit mod - Get a taxi in Singapore
JRL modded the MiniPov kit we sell in the MAKE store to hail taxi's better in Singapore. Turn it on, choose the text and as you wave it around it spells words in the air...
"Immediately I had in mind an application for it which would be to hail a taxi in Singapore.
I have therefore taken the original hardware and schematics of the project (see here) but have modified it slightly by adding one additional switch between pin 11 of the AVR chip and ground and one 10K resistor between the same pin 11 and pin 20. Then I have written a different program to run the device which allows me to have 8 different texts and permits the usage of bold and inverse attributes." - Link.
Source and binaries are on the site too, nicely done. Open source hardware begets fun like this.

DIY improvement to Apple's ear bud headphones
Fstedie writes -
"If you're like me, you've noticed that the sound and fit of your Apple ear bud headphones is not the greatest. Here's an easy way to improve both their sound and fit:
Find or buy an old Jabra cell phone head set. Ditch the headset and keep the ear gels (I found mine in my junk drawer). I've also seen them at swap meets for a couple of bucks.
Pick the right size for your ears. At least with mine, the size of the ear gels were almost perfect in size for the Apple ear buds. These gels "lock" in place inside your ear and improve the overall performance by isolating outside sounds and giving you a snugger fit.
Enjoy!" - Link.

SecureLED - Optical access control, with LEDs
This is pretty neat, uses LEDs instead of RFID. Requires line of sight to transmit, but that's actually a good thing...
"SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs).
Project Summary
This project started with one central premise: current physical access control systems are insecure in fundamental ways. We sought a way to remedy this problem, and came accross recent work which demonstrated the potential of communicating over cheap commodity LEDs. We used these as the basis of our system, building on top of it devices which use a cryptographically secure challenge-response protocol to authenciate a user.
As such, we built both a reader and a small key device (which we had originally planned to implement on an ATTiny2313, but did not for reasons listed below). The reader outputs the industry-standard Weigand protocol, so it is interoperable with current systems. All in all, we believe that this solution presents a powerful alternative to current technology. " [via] - Link.
Code is available on the site too.
