Precision Time Calibrator |
|
The Precision Time
Calibrator is a tool for analyzing and controlling the
performance of the Real Time clock in a PC. The program
queries atomic clocks on the internet and compares these
high precision time bases to the current time in your
computer. It then displays any error between your
computer and the atomic clocks. The display shows the
absolute error as well as a graph of how the error
changes over time. This makes it easy to see exactly how
much the clock on a PC drifts over time and allows you
to make adjustments to correct for drift. |

Windows Image Tracker.
Windows Image Tracker (WIT) allows you to track
any image on the internet over time.
If the images are comes from web cam
or any other source that changes
over time, the images can be
combined to create animations that
show how the images. This
is ideal for tracking weather radar, web cams, satellite images,
seismograph data and many other
things. The animations can be saved
and play later, creating a permanent
record of events. The are even tools
for enhancing and editing images. |

Sports Audio Delay |
|
12-8-2016: New Version!
|
|
Audio Delay.
Audio Delay
is a program that allows you to
delay any audio signal fed through
your PC. This is useful for
synchronizing audio with another
media source. |
For
example, people often like to listen
to local radio play-by-play
broadcasts of a sporting event while
watching the video on TV.
This used to be easy
because the radio and TV were
broadcast without any sort of delay.
However, now with satellite feeds
and digital broadcasts, the video
may be delayed by as much as 10 to
15 seconds. This is very distracting
and ruins the enjoyment of the game.
The Audio Delay program allows you
to feed your radio's audio through
your computer and introduce a
variable delay of from 0.1 seconds
to several minutes. This makes it
easy to synchronize the radio audio and
the Television video. |

|
New Version -
12-8-2016. This version
fixes a problem that produced
regular pulses and noise on some
computers when the program was run
in stereo or 16 bit mode. The
program also has an
Oscilloscope-style display that
allows you to see the wave-form of
the signals coming into the program. |

Spectrum Analyzer |
|
Spectracizer.
Spectracizer is a
program that allows you to do
spectrum analysis on your PC. The
programs takes audio signals fed to
the sound card on your computer and
does real-time spectral analysis on
displaying graphs the spectrum.
Spectracizer
can analyze signals ranging from 1
Hz to over 22Khz. It turns an
inexpensive laptop into an
instrument that can replace
equipment costing thousands of
dollars.
The program can
also analyze and dissect audio
files. Finally, it can also generate
synthetic wave forms and play
through the PC's speakers. The
spectrums can be displayed as
standard graphs or as spectrograms
which displays changes in the signal
over time. |

Used Car Price Evaluator |
|
Car-Buy-Rater. Car-Buy-Rater
is
a program for evaluating a used cars before you buy. It works by
calculating the amount of useful
life left in a vehicle and how much
it costs per unit. That gives you a
precise estimate of the value of the
car and makes it easy to see which
cars are the best value. Car-Buy-Rater
can save you thousand of dollars on your next used car purchase by
getting you the best deal. The program doesn't require "Blue Book"
values, so it will work old cars as
well as new ones. |

Terrain Modeling Software |
|
Terrain Modeling.
Estierra
is a complete terrain modeling software system. It converts Digital
Elevation Model files into photo-realistic 3D terrain that can be
viewed and manipulated in real-time. The terrain models can be
overlaid with aerial photographs to
give photo-realistic views of the
land surface. They can also be
overlaid with topographic maps to
allow precise location of land marks
and terrain features. This is similar to Google
Earth, but the terrain models are
higher resolution and narrowly
focused on small areas. |

XEdit - Programmer's Editor |
|
Xedit.
Xedit is an editor
specifically designed for writing
programs, but it’s also useful for
writing any kind of text. Xedit is
not a word processor and it does not
have fancy word processing features.
Instead, it concentrates on being
fast, powerful and efficient. It
makes an ideal replacement for
Notepad. |

XPL0 Programming Language |
| EXPL.
EXPL is a specialize version of the XPL programming language
that allows for program development under Windows. This version
of the language includes an
IDE with a
code editor, compiler and
simulated DOS/VGA console
that emulates 61 Standard CGA, EGA, VGA, and Vesa Modes. It also
includes a debugger that allows
the programmer to single step through programs, view variable
values, change variable values, set break points and step
through the low-level I2L opcodes that compose the program.
Finally, the language includes a set of more than 40
extended instrinsics
that handle the functions that would be handled by DOS or
assembly language in previous versions. |

Topo-Grabber - Free USGS Topographic Maps |
|
Topo Grabber.
TopoGrabber allows you to
download USGS topographic map
free of charge. The maps can be any
resolution including 30, 15 and 7.5
minute quadrangles. The maps can be
any size, including huge maps that
cover dozens of regular topographic
quadrangles. The maps can be printed
on single sheets of paper or on
multiple sheets that can be taped
together to create very large maps.

Update. Microsoft announced in 2012
that it was discontinuing their Map
Server that Topo-Grabber used to get
its topo maps. So many people
complained that for a while,
Microsoft relented and continued
supporting the server. Since then,
the server has been up and down. For
example, for several months around
the beginning of 2015, the server
was down. Later around the middle of
March 2015, it was back up, at least
for short periods of time. I don't
know what this means for the future
of the software. I will keep watch
the situation, and if it is
unreliable, I'll look for a new
server. |

Arachnid-32 |
|
Arachnid is a computer solitaire game originally written by
Ian Heath in the early 1990's. It is my favorite solitaire game and one of the
most challenging solitaire games that I have ever played. I've enjoyed playing
Arachnid so much that I have moved if from computer to computer, through various
operating systems starting with Win 3.1 and continuing through Win 95, Win 98,
Windows XP, Windows Vista, Windows 7 and Windows 8. |
 |
|
16-Bit Program.
Since it was originally written for Win 3.1,
Arachnid is a 16-bit program. Although it still
works fine with all 32-bit versions of Windows,
16-bit programs will not work under 64-bit
versions of Windows. For this, reason, I wrote
Arachnids-32, which will run under 64-bit versions of Windows. |
|
|
Eight Across |
| Eight
Across is a challenging Solitaire game. It is
more interesting and harder than the classic solitaire game and about
the same level of difficulty as Arachnids.
This version of
the program is based on a DOS program by Loren Blaney. The game was shown to
him by
Margret Rosenberg. |

3D Mandelbrot |
|
3D Mandelbrot. This program generates 3D
Mandelbrots using
Daniel White's formula. Daniel's formula
is an extension of the standard 2D Mandelbrot.
Most people use tracing to render
his 3D Mandelbrots, but I thought it would be
interesting to try OpenGL and 3D modeling. A 3D
model would have the advantage that you could
manipulate it in real time. The image to the
right shows an example of what the program can
create. |

Super Spiro - Advanced Spirograph |
|
Super Spiro is a program that draws broad range spirographs that go far beyond the drawings made by the popular toy. The typical spirograph generates patterns called
Guilloché patterns. Guilloché patterns are regular, symmetrical, circular patterns and a bit boring. Super Spiro can generate these patterns but it can also generate complicated, non-circular and asymmetrical patterns that are far more interesting.
