Squealing euros: Privacy protection in RFID-enabled banknotes.
(0/1459) / 0
There is widespread concern that Euro banknotes may provide an attractive new currency for criminal transactions. With this in mind, the European Central Bank has proposed to embed small, radio-frequency-emitting identi cation (RFID) tags in Euro banknotes by 2005 as a tracking mechanism for law enforcement agencies. The ECB has not disclosed technical details regarding its plan. In this paper, we explore some of the risks to individual privacy that RFID tags embedded in currency may pose if improperly deployed. Acknowledging the severe resource constraints of these tags, we propose a simple and practical system that provides a high degree of privacy assurance. Our scheme involves only elementary cryptography. Its effectiveness depends on a careful separation of the privileges o ered by optical vs. radio-frequency contact with banknotes, and full exploitation of the limited access-control capabilities of RFID tags.

First Law Of Thermodynamics: Conservation Of Energy
(0/1446) / 0
Defines a useful property called "energy". The two new terms in the equation (compared to what you have seen in physics and dynamics, for example) are the internal energy and the chemical energy. For most situtations in this class, we will neglect the chemical energy. Focus on the internal energy, u. It is associated with the random or disorganized motion of the particles. [broken link]

Servo modification for PWM control
(0/1424) / 0
Ringo Davis describes how to modify a Futaba S148 servo so that it’s speed can be directly controlled by using 2 pwm signals, 1 for forward, and another for reverse. I do not go into details on converting the servo to continuous rotation because that is already detailed in many places. The servos electronics consists of an Hbridge (BAL6686), another IC that monitors the incoming signal and the onboard potentiometer and creates the appropriate signals for the Hbridge, and a few support components. What I did was to remove the support IC and the potentiometer and attach wires directly to the Hbridge. [broken link]
