Neal Martini

Signal Generation Solution

Build an Inexpensive RF Signal Generator

Tired of going to a local university lab to use a signal generator, Neal designed his own. In this article he explains how he built the PIC16F877A-based controller and RF module.



Eric Kiser

Digital Decoding Simplified

Sequential Exact-Frequency Goertzel Algorithm

Using dedicated tone decoder hardware or digital signal processors to decode signals can cost a lot of money and take up precious space. Eric's algorithm is a great alternative.



Gordon Dick

High-Performance Square Wave Source

Build a Digitally Controlled Signal Generator

Wouldn't it be nice to have more than one square wave source on your workbench? Gordon built a digitally controlled signal generator around a PIC16F876 microcontroller and Linear Technology's LTC6903/6904 oscillator. It's a fairly simple, inexpensive project.



Romeo Costanzo

Strong Encryption for PICs

Part 2: Prototype Application

Now that you know how to use the Triple-DES encryption algorithm with PIC MCUs, it's time to learn how to use it to create a one-time password generator for an electric lock.



Michael Griebling

Hardware Synthesis with VHDL

Part 2: VHDL in Action

Ready to put VHDL in play? Michael shows you how to build state machines, decoders, mul-tiplexers, debounce and edge detection circuits, tristate bus buffers, shift registers, and more.



Bob Armstrong

Replacing a Legend

Build a Functional Equivalent to the CDP1861

Bob built a functional equivalent to a CDP1861 video controller chip so he could play video games on his COSMAC Elf replica. The design includes two ATF22V10 GALs and a few stan-dard 74HC chips. Ready to replace some random logic?



Daniel Malik

Inexpensive In-Circuit Debugging

Daniel's open-source background debug module (BDM) debugging interface is a great tool for the cost-conscious designer. It's perfect for in-circuit debugging MC68HC(S)12/S12X- and MC68HCS08-based applications.

Jeff Bachiochi

Capacitive Sensing Technology

Many exciting products like MP3 players include circular cursor controllers. In this column Jeff revisits the topic of capacitive sensing technology, which he last covered in 1999. He focuses on Quantum's new line of capacitive sensor ICs.

Silicon Update


Tom Cantrell

Batteries Not Included

The cholesteric LCD (ChLCD) is a new breed of LCD technology. One of its greatest attributes is that it eats up a lot less power than a traditional LCD. Read on to determine if it's the right choice for your next application.
