In case you missed them the first time around, here are our most popular posts from the previous week:
Our most read post is one about [Ben's] project where he created an electric motorcycle that has a range of 20 miles. This is a pretty comprehensive tutorial that goes into some good detail about what you will need to do to convert a motorcycle over to electric.
Coming in at second place is [dmw's] project where they created their own keyboard from scratch. We’re not too sure about the choice to stick the space bar(s) up in the corners but otherwise it looks like a really nice build.
Are you one of *those* people who likes to make the presents that they give as difficult as possible to open? Our #3 post of the week is one project that you should definitely check out. In this post, [Neowinian^2] shows how he and some friends encased some wedding cash inside of a giant cube of sugar!
Have you always wanted to say that you took some classes at MIT but were caught by the little technicality that you didn’t live in Boston? Fret no more my friend, MIT has just announced an online class program. You won’t be able to get a MIT degree remotely quite yet but this is a step in that direction.
Finally, we get to another keyboard project. This keyboard is a programmable keyboard that almost looks like the keypad on the end of an accordion (plus some other goodies). This keyboard was built by [Tim Tyler] and is designed to allow you to take full advantage of your thumbs instead of banishing them to the space bar.

In case you have been on vacation, here is the best that we have had on our blog in the past week:
In first place is a post about [the University of Pennsylvania's] quadcopter team. This time they have a group of twenty quadcopters flying in formation.
In second place is a post about a nice project by [Joel] where he converted an overhead projector into a TV projector by projecting through a LCD TV. He went all-out on this one by using a CNC machine to cut out a special holder for the LCD and the fans necessary to cool it.
Next up we have a post about a project where a 55 gallon plastic barrel is turned into a wind turbine. We’re not sure about how much power this would produce but it would probably be fun to play around with.
Following that is a follow up post about Printrbot, an inexpensive 3D printer which we previously posted about. It was a successful Kickstarter project a couple of months ago and now the design files have been released into the wild. Check it out!
Finally we finish off with a post about how to build a solid-state Tesla coil. It’s presented in an Instructable with 12 easy steps so that you too can feed your high-voltage addiction.

Another week has come and gone and that means that it is time for our week in review. These are the top posts that have been viewed at Hackaday in the past week.
Coming in at first place is a post about a project by [Red Jones] and [Brian Kast] of Sandia labs. Ethical issues aside, this is a pretty cool project. They have developed a bullet that can be shot out of a smooth-bore gun that can hit within eight inches of a target one kilometer away. That is pretty amazing. It does this magic with an 8-bit processor. This takes the microcontroller wars to a whole new level. Are they using Microchip, Atmel or (gasp) something else?
In second place is a follow up post to our post asking how to control three LEDs with three switches, all in series. That post, although it was posted in December 2011 came in at number three. Getting back on topic though, this week’s post shows how he did it! Not only that, but it shows the extent that he went to when making it. There is footage through the eyepiece of a microscope showing him building one!
Want to use LiPo batteries in your next project but are afraid to use them? Here is a post where [Paul] shows off a circuit that he built that can charge LiPo batteries using a MCP7813 chip from Microchip.
Finally, rounding out the five is a post about a blog that was taken down but luckily not before the IEEE made a copy of it. This blog was made by a robot operator working at the Fukushima nuclear plant and detailed their ongoing cleanup operations there.

Another week has passed and it is time to review the best of what hit our blog in the past week.
In first place is a repeat from last week showing how you can turn an Android device with a CMOS camera into a radiation detector.
In first place if we ignore repeats is a post about how the Raspberry Pi board can decode 1080p video! We’re just itching to get our grubbly little hands on some of these guys when they are finally released.
Up next is a project from one of our own. This week [Brian Benchoff] put up a post about how he built a manifold clock after seeing a similar project on Kickstarter.
Following that is a post showing how you can overlay video onto an encrypted HDMI signal. The MPAA would probably like to crack [bunnie] over the knuckles with a ruler for this one but he actually isn’t decrypting anything. Instead, he is encrypting the overlay and just replacing the normal video with it.
We like this next one a lot because it not only is a nice hack but it allows you to subtly control what can and cannot happen around you. Specifically, you can jam remote control helicopters with this device. It probably wouldn’t be too hard to pair this up with a TV B Gone to keep people from turning the TV back on once you have wrought your mischief.
Finally, another really neat one for you. In this post, we show [Sprite_tm's] radio transmitter that is composed out of two button cell batteries, two lengths of wire and an ATtiny processor. It is amazing that this even works but with the right tools, a good hacker can do just about anything.

In case you were asleep at the wheel, here are our top stories of the week.
Our most popular post was one that shows you how to make your own ‘personal assistant’ using Wolfram Alpha, text to speech software, and the phone network. It still won’t get your coffee though. You’ll just have to do that yourself.
Coming in at second place was a post about how to use your Android camera phone as a Geiger counter. Of course, this hack will work with any device that uses a CMOS sensor to do its imaging but they have gone and wrapped it up into a nice app.
Do you have access to a laser cutter and a burning desire (pun intended) to make gears? In this post Alex makes some acrylic gears using an Epilog laser cutter.
When is our government going to get it through their heads that we don’t want the internet to be controlled by a small group of corporations? Probably when the lobbyists stop giving them money by the boat load to do just that… It seems like several times a year a bill comes through that would severely restrict the internet or would at least allow someone to shut down a website without any sort of due process. Luckily, groups like the EFF are paying attention and are well organized for getting the word out there. This post was our stand against the current bills that threaten our internet freedom.
Finally, on a lighter note, we have a post about how to do ultrasonic welding on the cheap using a ‘heat staker’ and a small drill press.

For those of you who haven’t been paying attention in class, here is the best of what has hit our blog this past week:
In the #1 spot is a post about a project where some pretty ambitious hackers found a way to run Linux on a digital picture frame. Bravo!
Next up is a post where [Chris] needs some help getting his 1/10th scale, cycle accurate Cray I ‘supercomputer’ to boot.
In third place is a post about a very elaborate 737 cockpit simulator that was built over the past couple of years. This is a pretty intense build with lots of details about how it was done.
Following that is a post about a 3D-printed device that is similar to a phenakistoscope but instead of using slits to allow you to see the models in succession, it blinks some LEDs at the appropriate times.
Finally rounding things out in fifth place is a post about Makerbot Industries’ most recent release, which will let you print out your own phenakistoscope. This 3D printer is bigger than their makerbot and optionally sports two extruders instead of one so that you can do dual colors or possibly dual materials.

2011 was an interesting year here at Hackaday. We have about 24% more viewers now than we did last year. We started producing our own video content and we have shown some pretty interesting projects in our daily posts. In this post, we are gathering together the best of the best.
Our #1 post for the year with 175,000 views is about a 1 megawatt laser pulse pistol. Not only does this build work but it also looks cool. It’s definitely one to take a look at.
Coming in with 157,000 views is a post about how to insert your logo into a QR code. This one was done by our own [Brian Benchoff] and was a runaway success from the first week that we posted it.
In third place with 151,000 views is a post that could help you if you are trying to pick a development board to learn a new processor with. This post breaks down the various development boards available at the time of its writing into three different categories organized by price.
In fourth place with 114,000 views is one about an unique lock composed of color changing buttons. Your pass code is a series of colors instead of digits in an ordinary code lock. This build fits behind a standard wall plate so that it can be mounted cleanly using off-the-shelf hardware from the hardware store.
Wrapping things up at fifth place is a post describing how you can download books from Google using an utility called Google Book Downloader. We have no idea of the legality of this one. The original link is down but it seems that it is still available elsewhere on the internet.

In case you missed them the first time, here are our most popular posts from the past week.
In first place is a post that made our mothers’ wash our mouths out with soap. It is a periodic table of swearing!
Up next is a post about a micromouse robot that can run a maze faster than you would think is possible. Watch out lab rats, it’s gunning for your job.
Are regular violins too low tech? Would you rather play an instrument that could survive a few minutes with Chuck Norris and still keep playing the sweetest melodies? [Ken] created a violin out of carbon fiber that fits the bill.
Want to brake some aluminum? (or bend for the white collar folks out there.) In this post, you can see [Rupert's] build where he has created a metal brake out of little more than bamboo and some hinges.
Last but not the least is [Zach's] build that changes the brightness of his Christmas tree lights based on the pitch of the notes from the Star Wars theme.
