Thread: Introducing the LED Pro Modders Program

1. Introducing the LED Pro Modders Program

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.

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.
dll-files.com

PLEASE feel free to email or PM me with any questions or comments you might have about the program.

---- 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.

Nice ticey! I didn't see this one coming. [img]/ubbthreads/images/graemlins/wink.gif[/img]

Guys, ticey spent a lot of time on this. You should see how many times he updated it in like the last week. [img]/ubbthreads/images/graemlins/eek.gif[/img]

3. Re: Introducing the LED Pro Modders Program

Very worthwhile, whether you mod or just tinker around with LEDs and power supplies. [img]/ubbthreads/images/graemlins/grin.gif[/img]

4. Re: Introducing the LED Pro Modders Program

the monster has been unleashed!

oh...this project was hell to make, but hopefully you guys will find it worthwile! [img]/ubbthreads/images/graemlins/wink.gif[/img]

5. Re: Introducing the LED Pro Modders Program

Very nice for performing "what if" scenarios. This ought to save a lot of time. I'm looking forward to when I can get the download from the server.

6. Re: Introducing the LED Pro Modders Program

It runs fine on Windows XP; I tried it myself and then put the icon on my desktop.

7. Re: Introducing the LED Pro Modders Program

Thanks alot for the kind words guys. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Heres the direct link to the program exe file.

[EDIT] LED Pro should run on any Windows based PC.

8. Re: Introducing the LED Pro Modders Program

Dat what you've been working on ticey [img]/ubbthreads/images/graemlins/smile.gif[/img] Excellent [img]/ubbthreads/images/graemlins/thumbsup.gif[/img] Will give it a try.

9. Re: Introducing the LED Pro Modders Program

JT,

Yes, it downloaded that time. This is some sweet program. Many thanks.

Paul

10. Re: Introducing the LED Pro Modders Program

Those clear buttons are a thing of beauty. My favorite feature by far.

11. Re: Introducing the LED Pro Modders Program

ahh yes...we should give saaby credit for the clear buttons [img]/ubbthreads/images/graemlins/rolleyes.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

12. Re: Introducing the LED Pro Modders Program

jtice:

I'm having a small problem getting it to run. It says I need to install "MSSTDFMT.DLL" because the class isn't regestered. I'm running W2K SP4 and I have msstdfmt.dll in winnt\system32. Any help would be welcome. Jim

13. Re: Introducing the LED Pro Modders Program

snuffy,, PM sent

14. Re: Introducing the LED Pro Modders Program

Goto Run, by clicking the Start button.
Type in "regsvr32.exe msstdfmt.dll"

16. Re: Introducing the LED Pro Modders Program

Wow, cool!

Even got it to work under linux,using Wine ...

Great!

Olivier

17. Re: Introducing the LED Pro Modders Program

Well done. Now, I wonder how much further this program can go? What other functions are you planning to put in? [img]/ubbthreads/images/graemlins/smile.gif[/img]

18. Re: Introducing the LED Pro Modders Program

Looks really good!

19. Re: Introducing the LED Pro Modders Program

That's great. You can really get an idea of what would be the ideal setup for runtime very quickly without writting it all out algebraicly. This will save me time! [img]/ubbthreads/images/graemlins/thumbsup.gif[/img]

21. Re: Introducing the LED Pro Modders Program

Thanks alot guys.
I'm really glad all of you like it.

Steelwolf, What future plans? Well, basically anything you guys ask for. If I can do it, I will add it to the program. Be it a button, new calculation, whatever.

yclo, I have to give logicnerd411 credit for the sweet icon he made. [img]/ubbthreads/images/graemlins/smile.gif[/img]

The plans are... to make a "simple" mode. Where the user doesnt have to know all the numbers himself. Such as battery mAh. There will be a dropdown menu for each variable. And the user simply picks his brand of battery, and what size. I still dont know if this can be done properly, and the way I want it. And, even if it can be done, that version will not be out for a long time.

Please keep me updated to any comments, suggestions, or problems you might have.

Thanks again.

22. Re: Introducing the LED Pro Modders Program

Yes, a battery dropdown menu. That will be very user friendly. I had to make rough guesses. I was planning to look up all those data myself.

Although it may take time to make the upgrade, it will be of immense help. And then I'll be deleting some spread sheets that do part of what your program does. [img]/ubbthreads/images/graemlins/smile.gif[/img]

23. Re: Introducing the LED Pro Modders Program

This is awesome guys!!! Great work! This is truly what this place is all about! [img]/ubbthreads/images/graemlins/thumbsup.gif[/img]

24. Re: Introducing the LED Pro Modders Program

It wont run. I'm missing msstdfmt.dll
What is this wrote in? Wonder why I don't have the microsoft standard format dll...?

25. Re: Introducing the LED Pro Modders Program

Issac....
You probably DO have that dll file. For some reason, some syatems arent recognizing it properly.
Do the following, should fix the problem.

Goto Run, by clicking the Start button.
Type in "regsvr32.exe msstdfmt.dll"

26. Re: Introducing the LED Pro Modders Program

jtice:

Forcing it into the registry did the trick [img]/ubbthreads/images/graemlins/bowdown.gif[/img] thanks. Runs fine now, nice program. [img]/ubbthreads/images/graemlins/thumbsup.gif[/img]

OS info

28. Re: Introducing the LED Pro Modders Program

Ratus,

Hmmmm, thats a new one.
Run a search, if msstdfmt.dll isnt on your system at all, then that run command wont work.

If the dll file isnt in your Windows folder, then goto Microsofts website, and serch for the dll file.
If that doesnt work after installing that dll file, THEN run that RUN command.

Let me know if that does the trick.

29. Re: Introducing the LED Pro Modders Program

Apparently its a common problem.

I d/l a copy, stuck it in \system32 and did "regsvr32.exe msstdfmt.dll".

My suggestion is look on google, pick a site you trust and get a copy.

30. Re: Introducing the LED Pro Modders Program

Ratus,

I am in the process of seeing if I can imbed the dll file IN the program.
