I'm not a professional programmer but here are some programs I developed, using C++ Borland Builder, for fun and as tools. For this reason the programs are freeware. Anyone can download and use them at no charge... But... If you do so, is at your own risk... Like I do...
JBR-LotoMatic is a little program I developed to generate "wining numbers" for "La Loter�a Electr�nica de Puerto Rico". The numbers' range can be set from 6 to 99.
JBR-StandardResistor program gives you the Standard Resistor value for "any" given input, with its color code, and minimum possible tolerance in percent. You can select from two resistor types: 3-band or 4-band. Also help you learn the resistor color code.
JBR-Attenuator program is a handy tool to find the Standard Resistor values to build a T-type or Pi-type unbalanced or balanced attenuator. It helps when you have an impedance mismatch and can afford some attenuation to solve it. Searches for 3-band or 4-band type Standard Resistor values, and teach you the Standard Resistor color-code.
