[Boris] wanted to help ease his sister’s seasonal affective disorder. The most common way to do it is with fairly expensive light boxes. [Boris] built one of his own instead. Now his sister can blast her sadness away with over 10,000 lumens of CFL happiness. This is pretty much the same method one would use to create a ring light for photography.
This amazing looking set up is for photographing insects in flight. While this is similar to a past project we covered, this one seems to have several improvements. There are no longer any arms that you have to position on either side of the insect. This system uses an additional lens, picture at the top, to detect the reflected laser light off of an insect. Requiring only 40 microseconds to determine if the insect is in focus, capturing a flying wasp shouldn’t be too hard. You can see four lasers in the pictures, two are IR and used for focus, the other two are simply to help the operator target their bugs.

While doing serious fruitcake research, (no, really) we stumbled across the Great Fruitcake Toss held every January in Colorado. The particular entry above caught our eye. Omega 380 was built by a group of Boeing engineers and currently holds the distance record of 1,420feet. It’s a large compressed air cannon. All pressure is human generated using an exercise bike turning a pump. Apparently the team’s first contest entry was a classic surgical tubing slingshot. It eventually broke down during a very cold year, so they switched to this newer design. You can see more videos on the Operation Fruitcake blog.
Christmas has come early for us. This is our 3,000th post since launching Fall of 2004 doing just one post a day. The outstanding stat though is the 50,000 comments in the system. The team at Hack a Day would like to thank you, the readers, for bringing in all of our best tips and being part of this great community.
The Massachusetts Bay Transit Authority (MBTA) has dropped its federal case against three MIT researchers, “the subway hackers”. This happened in October and now the EFF brings news that the students will be working with the MBTA to improve their system. The overall goal is to raise security while keeping expenses minimal.
This whole mess started in August when a gag order was issued against the students’ presentation at Defcon. It’s a shame no one ever saw it because it covers a lot of interesting ground. A PDF of the banned slides is still online. They performed several attacks against both the subway’s fare system and physical security. Our favorites by far were using GNU Radio to sniff the RFID card’s transaction and bruteforcing Mifare Classic with an FPGA.
Until midnight tonight, you can download a free copy of the 1/2008 issue of security magazine hackin9. It’s 84pages, 10.5MB, and requires you to provide an email address they don’t verify.

Lensfree Ultrawide-field Cell-monitoring Array platform based on Shadow or LUCAS for short is an amazing new hack by a researcher at UCLA. This quick little hack involving only some wire, a filter, and an LED might revolutionize blood testing. This hacked camera replaces a unit that is usually the size of a refrigerator and very expensive to run. This is a pretty amazing achievement and should serve as inspiration for hackers all everywhere.
