This hack is an interesting twist that will allow you to get in or out of some parking garages when the attendant isn’t looking. Using something metal to trip the parking lot’s proximity sensor that is meant to let cars out automatically you can get into the garage or vice-versa without opening your wallet. A magnet from a hard drive might work a bit better because it is able to trip multiple types of sensors, but for this hack any kind of metal will work. This proximity sensor is a high–frequency oscillation type, so anything that attenuates, varies the frequency or stops the oscillation trips the sensor. When you can’t find a place to park, this hack will certainly impress your friends more than this method, but your street credibility could quickly turn into never lived down stories, if you end up driving over tire strips and ruining your tires, get a huge parking or trespassing ticket, or worse yet get your vehicle towed!

Defcon 16: MIT Boston Transit Presentation Gagged
[Zack Anderson], [RJ Ryan], and [Alessandro Chiesa] were sued by the Massachusetts Bay Transit Authority for an alleged violation of the Computer Fraud and Abuse Act after copies of their presentation slides were circulated at Defcon 16. The slides give an eye widening glimpse into the massive security holes present in the Boston subway system. There are at least 4 major security flaws in the subway, which allowed them to get free subway rides by finding unlocked, back door routes into the subway, spoofing magnetic and RFID cards, and attacking the MTBA’s network. Judge Douglas P. Woodlock has issued a gag order, stopping the trio from giving the presentation at Defcon or disclosing sensitive information for ten days. However, the MIT school newspaper, The Tech, has published a PDF of the slides online. The research culminated in the trio warcarting the MTBA’s headquarters and being driven off by police.
Black Hat 2008: FasTrak Toll System Completely Broken
FasTrak is the electronic toll collection system used by the state of California. Motorists can purchase a toll transponder for ~$26 and link the serial number with a debit account to have their tolls deducted automatically. Today at Black Hat in Las Vegas, security researcher [Nate Lawson] presented not just the privacy problems with FasTrak, but why absolutely no transaction from the tag should be trusted.

UV Drip Bicycle Tracker
[Che-Wei Wang] has a few more projects up his sleeve aside from his pneumatic power suit. This is a bit artsy, but he created an ultraviolet ink dropper to leave a trail of invisible ink wherever he rides his bike. Just think of it as a modernized version of [MacGyver]’s paint can under the bad guys car tracking system.
Drill Powered Mini Bike
DPX Systems seems to deal exclusively in devices powered by handheld drills. In addition to the mini bike in the video above, they’ve made systems for wheelchairs, toolboxes, and hoists. The device costs $630, but we know most of you just need prompting that something is possible to be well on your way to building your own version. We’re still more fond of weed whacker machines.

Motorized Unicycles
The Segway may be a technological wonder, but motorized balancing transportation has been around for a while. We’ve gathered up some of our favorite motorized unicycles for your knee scraping enjoyment.
The design above makes us immediately think of the very recent wonder by [Ben Gulak] that earned him the cover of Popular Science. Strangely enough, when reading about [Ben] we didn’t see any mention of Noah. Designed by [Andre Franca] of Brazil, it won 2nd place in the Plascar Automotive Design Contest in 2007. The designs are extremely similar.
Motorcycle Engine Powered Cars
Autoblog recently posted about the LusoMotors LM23, a track car powered by a Honda CBR1000 that weighs less than 900 pounds. We knew there have been quite a few other home built cars that have foregone traditional engines for motorcycle power plants, so we asked Google for a few project suggestions. It turned up this excellent round up of motorcycle powered cars by The Kneeslider. The usual Caterham suspects show up, but there are many other unique vehicles: from Mini and Fiat conversions to the unique sidemounted engine in the DP1 pictured above. Definitely check out this excellent collection.
