Designing high-current chokes is easy - 24-Jun-04 Issue of EDN
Somewhat unusually, this Design Idea deals with a formula rather than a
circuit. You might think that all the basic formulas of magnetic phenomena
were discoveredthan a century ago. In fact, they probably were, but, at
the time, some were of little practical interest and were essentially.....

Digital potentiometers enable programmable biquadratic filter -
22-Jul-04 Issue of EDN Of the many types of analog filters available
to designers, few allow easy adjustments of the filter parameters. The
biquadratic, or biquad, filter is an exception, however. You can change
that filter's corner frequency (ω0], Q,..... [Design Idea by Deborah

Display-Counter - Using a 4511, a specialized decoder IC, learn how to
drive a 7-segment display. The article explains the technique for counting from zero
to nine. this technique is the base for more complex applications, like a countdown
timer or a gear display for a motorcycle. (electronic design added 6/07) |

Easily Display Bit Map Images on Small Graphic LCDs - 11/19/98 EDN-Design
Ideas.....Combining a high-level language, such as Microsoft Windows, with low-level
assembly code or C++ code allows you to display perfect bit-map pictures on your
small-graphic LCD screen. You can use Microsoft Paint or any other bit-map-generating
program to define and edit the picture. Unlike..... [Design Idea by Todd Fitzsimmons,

Electronic Symbols Template - Over the past 15 years or so I have created
all sorts of symbols and icons and keep them in a template from which I copy-and-paste
whatever I need to create a circuit diagram. I decided to share this template with
anyone interested in creating beautiful and easy to read schematic diagrams, just to
keep our declining hobby alive. For ease of use, and you may have noticed, most of my
circuits are in .gif format and 256-colors palet. It is important to keep reading....

Embedded processor directly drives LCD - 9-Jan-03 Issue of EDN Driving
a bare LCD does not necessarily require specialized interface circuitry or
peripherals. This Design Idea describes an alternative drive scheme, which you
can easily implement using the general-purpose outputs of a microcontroller. Many
embedded-system applications need to interact with a user by displaying simple numeric
or alphanumeric characters..... [Design Idea by Daniel Malik, Motorola, Czech
Republic] |

Ericsson Cell Phone Display GA628 - The GA628 display provides a 12
character alphanumeric display , some icons in the second line and power consumption
of some 100 uA. It can easily be connected to the hardware, simply by soldering some
wires. The only disadvantage is , it needs a 3.3V power supply and something around
5.6V. However, this code and the MSP430 provides a clock for a simple charge pump,
realized with 3 diodes.... [Robert Tyrakowski] |

Excel offers painless LCD initialization - 20-Sep-01 Issue of EDN To
display a font or a symbol on an LCD, you need to convert the desired character into
numerical data. Creating the data for an entire font set requires specialized tools;
even with these tools, the task can be daunting. Alternatively, you can build a font
calculator using an Excel spreadsheet..... [Design Idea by Alberto Bitti, Eptar, Lugo,
