	IR REMOTE-CONTROLLER VIDEO MULTIPLEXER
		by Peter Gibbs Costly technicians and intricate equipment doesnýt have to coincide with multi-channel video monitoring. Peter shows us a system for visual monitoring that can be designed so you can make simple modifications yourself, rather than having to call in that pricey expert. Using off-the-shelf components, Peter succeeded at his task, while not obliterating the budget. November 2000
	A BETTER BATTERY CHARGER
		Part 2: Hardware and Software by Thomas Richter Implementation Now that youýve been introduced to the AVR Battery Charger Reference Design, Tom is ready to delve into the hardware and software. The ATtiny15 has special features that make it ideal for battery-charging applications. Take a look at the charge methods he details this time around. November 2000
	THE ETHERNET DEVELOPMENT BOARD
		Part 2: The Software and Firmware by Fred Eady Exposed Fred picks up where he left off and takes us through embedded Ethernet, as he explores part two of his online series. Looking at the Ethernet development board from a firmware angle, he covers a lot of information, but still reminds us, just as he does in all his print columns, that ýItýs not complicated, itýs embedded.ý November 2000
	STATE MACHINES
		by Ingo Cyliax In this installment, Ingo illustrates state machines using algorithmic state machine charts, implementing them through one-hot state encoding, the implementation of choice for FPGAs. Ingo takes us through the basic design methodology, using a simple design with two states. Here, the hardware has to depend on internal state, instead of just computing an output value. September 2000
	SCHEDULING REVISITED
		by George Martin This month, George addresses the wide response he received for his past scheduling article. How can you schedule for something youýve never done before? Well, keeping records is a good start. And, asking around to gather information isnýt a bad idea.
