New Educational & Science Software for Black Cat Systems

Graph Paper Maker lets you create your own custom sheets of graph paper. You have complete control over the graph characteristics. X and Y axis can independently be set for linear or log scale. Selection from a dozen standard paper sizes, or custom create...

Health Tracker is a simple yet powerful program which helps you keep track of and graph any health related measurement. For example, if you are diabetic you could track your blood glucose levels. For weight loss, you could track your weight, measurements...

The Atomic PC is a periodic table of the elements for Windows. In addition to the usual information found in such programs, The Atomic PC also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter...

DX Toolbox searches the web for you, gathering information on solar and geomagnetic conditions that affect radio propagation. In addition, the last month's worth of Solar Flux, A-Index, K-Index, Sun Spot Number, and background X-Ray Flux are plotted. Maps...

RF Toolbox is an antenna design and electronics or electrical tool package. It takes you step by step through the design of the antenna as: Dipole, Fat Dipole, Yagi, J-Pole, Super J-Pole, Log Periodic, Cubic Quad, and Vertical and helical. It also...

Diet Sleuth allows you to keep track of what foods you eat each day, and their nutritional value. For each day, you select the foods you have eaten, and the number of servings of each. Diet Sleuth will automatically calculate your caloric intake, fat...

Mac Grayliner displays a map of the entire Earth, showing day, night, and more importantly, the terminator between day and night. Studies have shown that enhanced radio propagation occurs between two points which are both on the day/night terminator. Mac...

The Atomic Mac is an electronic periodic table of the elements. It has detailed physical (melting point, density) and nuclear (isotopes, half-life) information. Decay modes and daughter products are listed for radioactive isotopes, and fluorescence and...

RadGen lets you use your GM-10 or GM-45 (serial or USB versions) to generate random numbers. Unlike the pseudo-random numbers generated by computers, these numbers, generated by measuring radioactive decay, are actual random numbers, ideal for...
