Nicely done, Modified easy bake oven. Jeri writes - Part of the home chip bath project, fiber optic manufacturing.
This was an attempt to make a small furnace that could be used for semiconductors and fusing fiber optics. It didn't work so well, but it might be worth trying again in the future.

Inspired by a heating pad they purchased, Windell and Lenore of Evil Mad Scientist Laboratories show how to make a fake seven segment display. Using a carefully constructed plastic bezel, a potentiometer, and some regular LEDs, they were able to create a faux digital dial, with a way cooler color scheme than one would find on regular seven segment displays. Nice hack!

Sunlight Labs, known for opening America's government, had a problem when they recently moved facilities. Creating new keys for team members was becoming costly, so they figured out an alternative method of providing secure access using a WRT54GL, easily sourced components, and a trusty copy of Make: Electronics. [Thanks, Nicko!]
With the firmware installed, I was able to SSH into the router and perform some simple manipulations of the system's GPIOs -- General Purpose Input/Outputs. These connect to things like the system's LEDs and switches, and can be controlled in software. I selected a GPIO that didn't seem to be used by OpenWRT -- it illuminates the "DMZ" LED on the front panel -- and wrote a very simple script to control it. I could now flip a tiny light on and off from a network connection.

Engadget disabled comments on their site because of the trolls, many other sites spend half their time battling people who chose to make others miserable - it's what the web has become in many corners of netland. MAKE will always have a vibrant community and great comments, that's a promise I know we can keep. We're going to post our refined comment policy up in the next 24 hours or so (stay tuned for a great post from Gareth on this). From the start of MAKE, 5+ years ago now, we've actively encouraged great discussions and try to jump in to resolve issues in the MAKE comments -- so far it's worked out pretty well -- MAKE is a safe place to post in the comments, it's a safe place to post your projects.
But other places are not and never will be.
This is where "shutup.css" comes in. I just installed it and I love it. It just removes the comments on many sites so you can enjoy the content and not the poop-fest.
I'm not going to pick on any specific site out there, but I think it's fair for me to say that I think the comments on some electronics-y related sites are pushing people away from sharing their projects lately. There are tons of great projects that make it to many of these sites, the editors do a great job with the sites and content, but there's just too many people who are determined to make the comments an awful place. shutup.css is now installed, I visit these site more now, even in the few short hours I've been using it - they get the page views and I don't need to accidentally glance at something awful. Eventually I think every site will work towards setting productive tones, it takes time and resources -- not everyone has a community manager for their site(s) - until it gets better on some of the sites I frequent, I think I'll use this comment blocker. shutup.css didn't come with every site I visit in the list so I needed to edit it. The sites it includes are digg, slashdot, youtube, etc... For youtube, I was using the Feynman quote-comment-replacer, that worked well - but I like this "clean" web without comments even better.

http://blog.makezine.com/archive/2010/01/sudoku_puzzle_solver_using_awk.html
awk is a fun and powerful language available in the command-line of Linux, Mac OS X, and even Windows (with a little help from Cygwin). In fact, our own Dale Dougherty co-authored one of the classic books on awk (and sed, another great Unix power tool) back in 1990 (the second edition was released in 1997), sed & awk.
At The Geek Stuff, Bill Duncan has posted a fun awk program that can solve Sudoku puzzles:
The application I chose to use as an example is "yet another sudoku puzzle solver". I must confess at the outset that I have never sat down to solve one of these puzzles myself, but sketched this out over a few days while commuting on a train and watching other people work on them. It was far more fun I think than actually doing any of the puzzles..
[...]This program uses a very simple depth-first recursive backtracking algorithm with up-front and ongoing elimination of invalid entries. Awk may not have the expressive power for representing complex data that perl or other languages have, but with care, many moderate sized problems and data sets can be used. This algorithm may not be the best one around, but it is certainly fast enough for most problems and is easy to implement.
When you strip out blank lines and comments it's only 67 lines! Keeping in the awk spirit, that would be:
awk '!/^[ \t]*#/ && !/^$/' solve.awk | wc -l
Yet Another Sudoku Puzzle Solver Using AWK
If you need to generate some puzzles to throw at it, try this Sudoku Generator written in Python.

Coins to Frequent Flier miles "hack" via DF.
Enthusiasts of frequent-flier mileage have all kinds of crazy strategies for racking up credits, but few have been as quick and easy as turning coins into miles.Read more | Permalink | Comments | Read more articles in hacks | Digg this!
At least several hundred mile-junkies discovered that a free shipping offer on presidential and Native American $1 coins, sold at face value by the U.S. Mint, amounted to printing free frequent-flier miles. Mileage lovers ordered more than $1 million in coins until the Mint started identifying them and cutting them off.
Coin buyers charged the purchases, sold in boxes of 250 coins, to a credit card that offers frequent-flier mile awards, then took the shipments straight to the bank. They then used the coins they deposited to pay their credit-card bills. Their only cost: the car trip to make the deposit.Richard Baum, a software-company consultant who lives in New Jersey, ordered 15,000 coins. "I never unrolled them," he says. "The UPS guy put them directly in my trunk." Patricia Hansen, a San Diego retiree who loves to travel, ordered $10,000 in coins from the Mint.

Biohacking: Hacking goes squishy @ The Economist
MANY of the world’s great innovators started out as hackers—people who like to tinker with technology—and some of the largest technology companies started in garages. Thomas Edison built General Electric on the foundation of an improved way to transmit messages down telegraph wires, which he cooked up himself. Hewlett-Packard was founded in a garage in California (now a national landmark), as was Google, many years later. And, in addition to computer hardware and software, garage hackers and home-build enthusiasts are now merrily cooking up electric cars, drone aircraft and rockets. But what about biology? Might biohacking—tinkering with the DNA of existing organisms to create new ones—lead to innovations of a biological nature?
And as the price falls, amateurs are wasting little time getting started. Several groups are already hard at work finding ways to duplicate at home the techniques used by government laboratories and large corporations. One place for them to learn about biohacking is DIYbio, a group that holds meetings in America and Britain and has about 800 people signed up for its newsletter. DIYbio plans to perform experiments such as sending out its members in different cities to swab public objects. The DNA thus collected could be used to make a map showing the spread of micro-organisms.

Having a party at night? Make it easy to find the right beverage by following vader119's directions and add a light to your cooler!
Trying to maintain an outdoor worm composting bin in the Texas heat? Instructables user coopdaddi shows how he added a water chiller and a fan to make his cooler a perfect place for worms!
Have the opposite problem, and need a way to keep your resin/RTV project warm while it cures? Why not convert your cooler into a low-temperature curing oven by following idmains instructions? Bonus points for adding a mechanism to control the inside temperature.
So, that's just about everything I can think of to do with a cooler. Have any last-minute ideas? Be sure to share them in the Comments for a chance at a prize!

However, neither of these would help if you are stationary, so how about a remake of the infamous RC cooler?

Every year, Joe Grand, aka Kingpin, aka The Sultan of Solder, and hardware hacker extraordinaire, designs the badges for Defcon, the annual hacker convention in Vegas. The badges are more than just conference ID badges, they have electronics on-board that do something, and conferees have to figure out what that something is. There's also a Badge Hacking contest, to come up with some cool, outrageous, ingenious hack of the badge. Winner gets an Uber badge, which gets them into Defcons for life.
This year's badge uses the Freescale MC56f8006 DSC (Digital Signal Controller), has an on-board mic, and an RGB LED. Apparently the LED pulses out the morse code of a web address. At that address is a few goodies, like a sketchbook of designs for a badge (a page is seen above), an MP3 song, and most importantly, all of the badge tools, source code, CAD files, etc. According to the discussion on Hack a Day, it appears to do some pretty ingenious stuff (like physically network with other badges).

Wireless keylogger via HaD...
Familiar with the concept of hardware keylogging? A hardware keylogger is a perfect solution for monitoring user activity, at very low risk of disclosure. A hardware keylogger is a purely electronic device, so no access to the operating system is required, no traces are left, and software has no possibility of detecting such a device. However, the hardware keylogger concept inherits one weakness: physical access to the keylogger is required for retrieving captured data. This problem has finally found it's solution: a Wireless Keylogger.Next project, how to make a wireless keyboard jammer :)
KeeLog has already released one open source PS/2 hardware keylogger design to the public. Now, we are doing it again with the DIY Wireless Keylogger. This design is fully free for private and commercial use...

When I first saw this picture of a cross with a concealed dagger blade, I assumed it was the work of an artist trying to make some sort of political statement about religion and/or violence and/or the relationship between the two. Which, frankly, would neither interest nor impress me very much. Turns out, however, that quite the opposite is true--this object was created for entirely practical reasons. In spite of what appears to be very workmanlike quality, it is in fact a shiv, secretly manufactured by a prisoner in Germany as an expedient concealment for a personal weapon. It was later discovered by his or her jailers (before being used, one hopes), and eventually photographed by Marc Steinmetz, who has assembled a remarkable online portfolio of pictures of improvised weapons and other prisoner's inventions. Thanks to Thomas Howery for the lead.

So-called Continuous Ink Systems (CIS) are after-market goodies that attach to your inkjet printer, replacing the pricey consumable ink cartridges with permanent cartridge-heads that are continuously refilled from external ink bottles connected by silicone tubing. So to replace the ink in the printer, you just pour more ink in the bottles. Here's a good review of an aftermarket CIS system priced at $250 (which still seems like a lot to me since it's basically just a couple hundred grams of injection molded plastics.)
The idea of a CIS is simple enough, and beautifully subversive of the military-industrial-inkjet complex, but it's received surprisingly little attention from the DIY community. Eddie Matejowsky of Brisbane, Australia, has one of the very few pages I could find on DIY CIS, and its records of his experiments--both successful and otherwise--make very interesting reading for those interested in the idea.
Know of other cool pages about this? Drop me a link in the comments!

The Tin Can app takes advantage of the iPhone's audio ports to send and receive messages using sound. This deceptively unadorned app points the way to jailbreak-free hardware solutions for the iPhone -
For those of you who are technically inclined, Tin Can uses frequency shift keying (FSK) to send data from one iPhone to the other. This is the same technique used by early modems to transmit data.
FSK uses alternating frequencies to represent binary data. For instance, to transmit a '1' using FSK you might use a 4 kHz signal, whereas to transmit a '0' you might use a 3 kHz signal. You would then alternate the two frequencies to send sequences of ones and zeroes.What we have done, in essence, is turn the iPhone into a simple modem using its speaker and microphone. Pretty cool.

FSK uses alternating frequencies to represent binary data. For instance, to transmit a '1' using FSK you might use a 4 kHz signal, whereas to transmit a '0' you might use a 3 kHz signal. You would then alternate the two frequencies to send sequences of ones and zeroes.What we have done, in essence, is turn the iPhone into a simple modem using its speaker and microphone. Pretty cool.
