Tracking Dual Rail Power Supply:  This article details the construction of a bench top power supply that can be used to power circuits or devices during development work in the lab. More specifically it is an adjustable, tracking, dual rail supply which means there are two supply voltages, one positive, one negative, that are adjusted by a common potentiometer such that supply voltages are equal in magnitude. It is capable of supplying up to +/15V DC at up to 1A. This is sufficient for the majority of small signal e.. (added 1/06)

Ultrasonic Range Finder uses Few Components:  06/24/99 EDN-Design Ideas  (added 1/06) An ultrasonic, or sonar, range finder is a common sensor in robotic systems and industrial environments. Even home and automotive uses are possible. A novel sensor design consists of a WC, a few peripheral components, and a pair of ultrasonic transducers (Figure 1). The range-finder module consists of a WC, a transmitter, a receiver, a direct-receive inhibit circuit, and an RS-485 interface. The module's usable range is approximately 4 in. to 16 ft with an accuracy of approximately ±2 in. This performance is sufficient for many industrial, automotive, and robotic uses....
