	BREADBOARDING
		by Stuart Ball With this offering, Stuart pumps new life into the dying technique of prototyping. For electronics experimenters, the cost of making a circuit board is too high for building only one. There is another choice. One-of-a-kind prototypes can be produced without having to lay down the cash for printed circuit boards. Hand-wiring may seem laborious, but youıll end up with an effective low-cost alternative. December 2000
	IMPLEMENTING A SIMPLE USB INTERFACE
		For an Embedded Processor by Stuart Allman When connecting modules in your embedded system, decisions need to be made. The universal serial bus (USB) may help you make up your mind and ease the aches of development. With the news that Intel is phasing out the good old RS-232 and replacing it with the USB, Stuart shows us that all is not lost, because the USB should work just as well. He supplies us with all the info and leaves no room for excuses, so get ready to make a game plan for your next design. December 2000
	DETERMINING MEASURMENT ACURACY
		by Hristo Stefanov To measure different signals, youıve got to define the terms of measurement. Most of us use the term "error" in assessing uncertainties. Because every measurement has some amount of error, there is always inaccuracy, which can be attributed to many factors. In this article, Hristo takes us through a series of different types of errors, from random to systematic. December 2000
	THROUGH THE LOOKING GLASS
		Taking a Look at the PIC18Cxxx Series by David Brobst If youıre looking for high-end, look no further than Microchipıs PIC18Cxxx family of 8-bits. Designed with the future in mind, its direction seems clearıwith increased clock speed, hardware multiplier, and higher resolution A/Ds, this new unveiling is positioned as a low-end DSP solution. With intriguing features like the table read/write capability, David shows that the PIC18Cxxx is a valuable addition to the growing line of controllers. December 2000
	SIMPLE THINGS
		Prime Numbers Revisited by George Martin This month, George looks at design problems and examines where to look for the answers. He explains that, typically, he calls on a hardware engineer for logic problems and the like, and a software engineer for help with pure software tweaking. Sometimes heıs led down a blind alley, but shows us that by tapping into all of the sources available, you could be surprised to find that the answers may come from the most unlikely places. December 2000
	RAMBLIN' MAN
		by Tom Cantrell The name of the game is networking and automotive electronics is the target. In this article, Tom predicts a time when cars will be Internet-enabled, but the standards for such road warriors are in the limelight as well. Cars and chips together open up a wide array of possibilities, but when car manufacturers roll their own standards, you could find yourself tripped up on new wires. December 2000
