I am very happy to announce the release of The LED Pro modders calculation program.
This program started out as a simple runtime calculator, and grew to a complete modders calculator. Capable of calculating any variable. One of the best features about this program is its ability to reverse calculate. This means that you can leave any one of the fields blank, and LED Pro will calculate the answer for you.
--- LED Pro is capable of calculating the following ---
For Converter Boards such as Dat2zips BadBoy and DownBoy boards: mA Current to LED, LED Vf, Input Battery Voltage, Battery mAh, Runtime, and the converters Efficiency.
For Resistors: mA Current to LED, LED Vf, Input Battery Voltage, Resistor Ohms, and Resistor Wattage.
You can find more information and the Download File HERE.
Check back to the WebSite for updates and more information.
I hope all of you can find this program useful. It has cost me many headaches and sleepless nights. But, I feel that in the end it will be well worth it, if it serves as some use to all my fellow CPF Members.
Having a problem with msstdfmt.dll ??? Do the following.
Search for the file in your WINDOWS directory first. If you have it.
Goto Run, by clicking the Start button.
Type in "regsvr32.exe msstdfmt.dll"
If you dont have it. Try one of the below sites to download the dll file.

---- Update: 2-9-04 ------
When using LED Pro, and calculating the resistance to use with a number of LEDs in parellel, the resistance displayed, is the total resistance that should be placed before the parellel group of LEDs.
This is not always a good idea. If the Vf(forward voltage) of the LEDs differs, this will cuase the LEDs to recieve different levels of current.
To prevent this, a resisrtor should be placed before each LED.
To do this, take the value that LED Pro calculates, and multiply it by the number of LEDs.
Example: Desired LED Current= 300mA
LED Vf= 3.6
Battery Input Voltage= 12
# of LEDs in Parellel= 3
Resistance Value Calculated= 9.33 Ohms
Take 9.33, and multiply it by 3.... = 27.99 Ohms
So, place a 27.99 Ohm Resistor (or the closest possible resistor) before each LED in the Parellel group.
