Easy V2. 0 contributed by Puiu Chiselita from Romania. . . . [Wichit Sirichote, designer]
VG Converter for Video Projectors &
Fixed Frequency Monitors - . . . [Designed by Tomi
Engdahl]
VG Generator - that displays an image in the XS Board RAM on a VGA monitor. . . .
VGA Hardware Screen Blanker - This design was published in
the June 1994 issue of Electronics Australia, and has proven extremely popular. The kit was sold by Jaycar
Electronics, but has since been discontinued. It is a simple device that connects between your keyboard and VGA
card feature connector, and will blank (or blink) the screen after a certain amount of non-keyboard activity.
This device is totally software and O/S independent. The ONLY screen blanker that can be guaranteed to work. . .

VGA to RGB + composite sync-converter - This article consists of one circuits which I have designed for connecting VGA card to other
display devices than just a VGA monitor. This circuits makes it possible to connect your VGA card to fixed
frequency monitors and video projectors. For some applications and system combinations some additional software
is needed to get the system working. . . [written by Tomi Engdahl]
VGA to TV Converter - This article consists of one circuits which I have designed for connecting VGA card to other
display devices than just a VGA monitor. This circuits makes it possible to connect your VGA card to fixed
frequency monitors and video projectors. For some applications and system combinations some additional software
is needed to get the system working. . . [written by Tomi Engdahl]
VGA to TV Scart - This VGA to TV converter is designed to connect VGA card to a television which has suitable
21-pin AV connector for RGB input (called EURO/SCART/Peritel connector). if you Tv does not have this kind of
connector, then you can't use this circuit. . . [by IQ Technologies Industry, unless otherwise noted online]
VHDL
procedure dynamically opens a file - 12/17/98 EDN Design
Idea (File contains many circuits. Scroll to find this one. ) A simple VHDL-87 procedure opens a file whose
name a command file or user conveys in runtime. You can apply this technique to the reading or writing of data,
control, and status files. This procedure is useful for replacing the input stimuli file of a testbench without
recompiling the code (with a different stimuli file name) or rename the stimuli file name. In addition, the
procedure can write the simulation results to a file whose name consists of the input file name and any preferred
extension. . . . [by Jacques Behar, Rockwell Semiconductor Systems, San Diego, CA]
Video Amplifier Design for Computer Monitors - Application Note. . . [National Semiconductor]
Video Clock Superimposer Using Pic16c711 - As a followup to my VCR Pong project, here is a gadget that is actually useful in the Real
World! It superimposes the time of day, in "HH MM SS" format, in the bottom right-hand corner of an existing
video signal. My friend Scott uses it with his home security system. . .
Video Connectors - This connector is found on most Intel-PC's. It's quite easy to feed VGA-monitors with
Macintosh-signals (or the other way around: attach a Mac-monitor to an Intel-PC). Most modern VGA-monitors are
quite tolerant regarding vertical- and horizontal-sync frequencies. . . .

Virtual USB Keyboard
based on an Arduino - . . .
Visor cradle serial interface - The Handspring Visor / Visor deluxe is usually shipped with a USB cradle but this fairly
recent interface is not supported by old PCs or PCs running under Windows 3. x, Windows 95 or Windows NT4. In
that case, HotSync can be done only via a RS-232 connection. Fortunately, the Visor supports both serial and USB
interfaces but its serial inteface is neither RS-232 compatible nor TTL compatible. This project is aimed at
building a small circuit that fits into a standard USB Visor cradle and that adds RS-232 capabilities. Note that
Handspring sells a serial cradle but if you have more time than money, do it yourself and you will have a 2 in 1
cradle. . . [Big Lolo Ferrari]
Visual Basic models MDAC
offset - 02/18/98 EDN Design Idea (contains several
designs, scroll to find this one) It's hard to imagine that, for such an old-hat item as a standard R-2R
multiplying DAC (MDAC), there still exists some "dark area" in modeling and calculating its dc offset, VOFF, and
related output resistance, RO. You can obtain some information from References 1and 2 and other references
regarding the code dependency of RO and VO, but the simplified formulas given therein are insufficient for
thorough engineering analysis/design and computer modeling/simulation. . . . [by Olga Belousava, Los Alamos, NM,

Voltage-to-pulse-width converter spares microprocessor's resources - 12/01/07 EDN Design Idea Simple circuit uses only three components and two I/O-port
pins. Although not an ADC in the classic "stream-of-ones-and zeros" sense, this voltage-to-pulse-width converter
produces a logic-level output pulse whose variable width represents an analog of . . . [by James Christensen,
