Improved LED Menorah

November 13, 2008 by 7 Comments

Reader [Mike] was not too impressed by design in a recent post we did on an LED menorahs. Doing what any self respecting hacker would do, he designed and built a better one then sent it in to us. He just happened to have an AVR ATtiny13 sitting around, so he used that for the brains. It has single button operation, is powered by 2 AA batteries, and even simulates the candles burning out. His custom PCB turned out quite nicely as well, the power plug connects to the batteries in a way that uses them as a base. Check out his site for detailed plans and source code. Great job [Mike].

Flying Cars A Reality

November 13, 2008 by 21 Comments

[Stillboy] alerted us to a flying car that runs on biofuel. Flying cars have been the mainstays of science fiction and technological wish lists for years, but they elude production, as expenses, fuel, and gravity get in the way. [Gilo Cardozo], a paramotor manufacturer, managed to overcome those hurdles by thinking simply. He attached a paramotor to his car, which is powered by a Yamaha superbike engine and a gearbox from a snowmobile. His modified Rage Motorsport buggy is street legal in the United Kingdom, and in the air, can get up to 80 miles per hour. It will be fully tested in January, when he and his chief pilot and expedition organizer [Neil Laughton] drive and fly the car to Timbuktu.

Other flying cars are also in the works. DARPA recently announced their Personal Air Vehicle Technology project that will hopefully lead to a military-suitable flying car that can get up to 60 miles per hour on the ground and 150 miles per hour in the air. Moller International claims that a flying Ferrari is in the works, and could be available for purchase within two years. Are jet packs next?

Working With High Quality YouTube Videos

[Kottke] posted advice for watching and sharing high quality YouTube videos. While it’s not HD quality, it’s much, much better than the normal, fuzzy quality you get on most videos. This hack has been available for some time, but it hasn’t been documented very well until now. When you’re logged in, you can just set the default to “Always play higher-quality video when it’s available”. When you’re linking to a video, add &fmt=18 to the YouTube URL. This also works when you’re embedding the link in WordPress. If you’re not in WordPress, then tack &ap=%2526fmt%3D18 onto each URL in the embeddable code. It’s pretty simple, and makes wasting your day at work much more enjoyable.

Take a tour of the Mutex laboratories, where mutants are made and nothing could possibly ever go wrong. [Steve] directed us to these videos of the Halloween set up he did with his son this year. Neighbor kids got to go on an action packed tour where mutants break free from their cages and have to be neutralized with special ray guns. Wow, why didn’t this guy live near us when we were kids? Check out a behind the scenes walk through with some good technical stuff after the break.

Recovering Photos With PhotoRec

November 12, 2008 by 17 Comments

A coworker approached us today with a corrupted SD card. It was out of her digital camera, and when plugged in, it wasn’t recognized. This looked like the perfect opportunity to try out [Christophe Grenier]’s PhotoRec. PhotoRec is designed to recover lost files from many different types of storage media. We used it from the command line on OSX, but it works on many different platforms.

It’s a fairly simple program to use. We plugged in the card and launched PhotoRec. We were prompted to select which volume we wanted to recover. We selected “Intel” as the partition table. PhotoRec didn’t find any partitions, so we opted to search the “Whole disk”. We kept the default filetypes. It then asked for filesystem type where we chose “Other” because flash is formatted FAT by default. We then chose a directory for the recovered files and started the process. PhotoRec scans the entire disk looking for known file headers. It uses these to find the lost image data. The 1GB card took approximately 15 minutes to scan and recovered all photos. This is really a great piece of free software, but hopefully you’ll never have to use it.

Company Shutdown Causes 2/3rds Drop In All Spam

November 12, 2008 by 26 Comments

The Washington Post is reporting that the shutdown of one hosting company has caused the total volume of spam to drop by 2/3rds. The company in question is McColo Corp. Both Hurricane Electric and Global Crossing pulled the plug today after a damning report revealed a number of illegal activities happening on McColo’s servers. McColo already had a reputation with the security community. When contacted about abuse, the company would often shift servers to new IP ranges instead of shutting them down. Although not the main source of spam, the company was host to many botnet control servers and phishing sites.

Meggy Jr RGB Portable Game Platform

Evil Mad Scientist Laboratories have just announced the release of the Meggy Jr RGB, a fully programmable handheld console with an 8×8 RGB LED matrix display. Like its big sisters Peggy and Peggy 2.0, the Meggy Jr is driven by an ATmega168 microcontroller and is made up of a bank of fully addressable LEDs. Unlike its siblings, the device boasts six buttons and the ability to be mounted inside of a custom case (or “handle set”) constructed from plastic or wood, drastically altering the look of the console. Using the popular open-souce Arduino environment, users are able to write custom software for the device. While it works great as a game console, of the many possible configurations and suggested uses, we think “disco floor for your Lego minifigurines” is the most amusing.
