Internet And The PCB
by Robert Schnyder
The Internet has transformed business in a very profound way. Similar to the impact of the Industrial Revolution, the Internet has generated tremendous opportunities for growth and expansion. It has created an entirely new way of thinking about the concept of business. Page 0

The PID Controller - Part 1
by Aaron Dahlen
In this series of articles, we will explore how to implement both analog and digital control systems. We will be using a PID (Proportional Integral Derivative) controller. With a PID controller, we can control thermal, electrical, chemical, and mechanical processes. The PID controller is found at the heart of many industrial control systems. Page 0

Video Basics
by Keith Jack
Although there are many variations and implementation techniques, video signals are just a way of transferring visual information from one point to another. The information may be from a VCR, DVD player, broadcast channel, cable television, satellite system, the Internet, or one of many other sources. Page 0

Calculating Current

by Mark Dobrosielski

An LED is one of those product components that just has to work. If I look at my computer from across the room and don't see its LED winking back at me, I assume it's turned off; I never expect that the LED might have burned out. There's good reason for that: When operated within specs, an LED has a lifetime of 100,000 hours or more. Page 0

Simple Shaded Pole AC Motor

by Richard Panosh

As early as 1821, Michael Faraday demonstrated that continuous rotary motion could be produced by passing a DC (Direct Current) current through a wire in the presence of a magnetic field. Page 0

The Ever Shrinking µC - PART 2

by Peter Best

If, after reading Part 1 last month, you’ve been wondering why there are two PIC10F206s on the Little Bits Development Board, here’s part of that answer: The inverter pair we just implemented can be tested by simply moving jumpers carrying the desired logic levels between the inverter inputs and watching the inverter outputs on the LEDs.

Near Space
by L. Paul Verhage
Adapting Cell Phone Battery Cells for Near Space Use
Due to the extreme cold of near space (NS), hobbyists must be careful when selecting power sources for their NS craft. On one or two occasions, I have lost track of a NS craft, apparently due to cold batteries. To reduce this risk, most of us involved in amateur NS use lithium cells, which can be rated to -60° F.

In The Trenches
by Gerard Fonte
Analog To Digital Conversion Considerations
This month, we'll examine the error sources and problems that occur when the necessary attention to detail is ignored. Page 0

Let’s Get Technical
by James Antonakos
Hop, Skip, and Jump
Everyone seems to be jumping onto the wireless networking bandwagon. With more and more devices going wireless, the airwaves are constantly filled with numerous digital “conversations.” For ordinary, law abiding wireless users, the congestion is handled using a wireless protocol that allows for reliable communication in a noisy, competitive environment.

Micro Memories
by Edward B. Driscoll, Jr.
The Yamaha CX5M: The Music Computer - 80’s Style
These days, recording music on a PC is a surprisingly straightforward affair. Once you master a program like Cakewalk’s Sonar or Steinberg’s Cubase, it’s a matter of if you can dream it up, you can record it. With programs like Sony’s Acid, you don’t even need to be much of a musician: just layer various loops to taste and you can start making music. Page 0

Stamp Applications
by Jon Williams
Timing Is Everything
It wasn’t very long after the BASIC Stamp and other BASIC language microcontrollers appeared that advanced users started asking about using interrupts. Well, neither the Basic Stamp family nor — to my knowledge — any of the micros in the same class supports true interrupts... Page 0
