It is really hard to find good information online about proximity cards. I’m sure some companies consider this obscurity a form of security, but Jonathan Westhues demonstrates how severely flawed that notion is. He found a data sheet mentioning a 125kHz carrier frequency. He was off and running from there, eventually building a device that can read and repeat a proximity card’s data. It’s been argued that RFID technology is safe because of the short read distance. Jon actually found it easier to passively read cards that were being energized by a legitimate reader than by the device alone. Make sure you check out his home built PCB mill while you’re at the site.

quite awhile ago, the big thing to do was to impress your friends by rockin the debug menu on the coke machines around your mall. well, everyone forgot about pepsi

ahhh, yes. we knew one day that 400mhz would not be the fastest thing in the world on a pc. it’s gotten so out of control, that this juicer is a 433mhz beast of blending fury, well….two microcontrollers worth. It’s got wireless and it makes the absolute perfect juice combination. Using built in sensors and other fun stuff, it can measure the exact proportions for your custom made apple juice….everytime. It takes it’s commands via a keyboard or wireless remote and dispenses juices from above. My god, this world is getting better everyday. What’s next cornell? Wireless Egg beaters?

there are a few movies out there that have some nutty storyline that involves some guy using brand new fingerprints so he doesn’t get caught. i think one is Gone in 60 seconds but i might be wrong. anyways, we’ve all wanted to go get new fingerprints and proceed to go wild with our new identity. well it’s possible to do it and it’s not insanely hard. Plus, in the process you’ll learn how to dust for fingerprints like a real detective! but if you have a home depot or hardware store with all the supplies near you, a free afternoon, and patience, you’re one step on your way to a new identity. who’s got the coolest fingerprint is the question to ask obviously.

my kinda hack right here which im sure many of you can relate to. this alarm clock is not just an alarm clock. it is one that is scared. scared of shock. thus, if you punch, kick, chuck a dremel at it when the alarm goes off, it will remain quiet. this is no simple hack mind you, but it’s not too hard if you can solder onto a pcb board and read hand-made plans just fine. a little more soldering and you’re done! you can now kick you alarm clock at will to make it snooze. you snooze, alarm clock = lose. very nice hack [mr. hackadayfan]

i highly reccomend checking out the “greatest hits volume 2” video. lots of laughs.

now this is truely going beyond the boundries of hacking. to even conjure up this kind of hack is not only awesome, but technically illegal because you can’t destroy money here in the USA. Well if you’re willing to risk breaking that law (we sure are) and you’ve got a silver dollar handy (or a quarter works we’ve gotten emails about). you just basically, bend the coin inward, polish the outside like a ring, then hollow out the inside to fit your finger.

thanks [AJ] and to all readers for letting us know how to identify currency <3
