very nice

Just used this to get a rough ballpark figure on my (now working again) RPK's FPS, as I used a mixed mag of .2s and .25s, giving a range of readings. Worked very well. +1 to you.

[visionviper]

Thank you.

I am glad you guys like it.

Any suggestions on what to include for later releases would be good. I am trying to think of things to include, but I can't think of any yet.

One thing I do plan to do is to make it a lot nicer looking, make it more pretty.

you could add a charge time calculator, and a calc for what setting to put it on. I forget the details but i know its been talked about. also if possible, a fps/mps + bb weight = joules calculator

note, i havent downlaoded the program, so if any ofthose are already on therre, sorry

[visionviper]

Those all are on there.

[mtdarkwolf]

shows what i know.

*Goes to download program*

nice job dude making this

much better than before

Perhaps a calculation of the distance the bb will travel, depending upon weight and velocity?

I couldn't see it on the application, but I was looking purely for velocity and force the other day. I know with variants like wind it can be hard to predict, but a rough ballpark figure pre-wind would be handy for individuals curious to see what sort of range they can expect.

Erm...

You don't need to know the weight to work out the distance... sort of.

If a gun is shooting at 1J, for example, a 0.2g BB is travelling at 100m/sec. In half a second (roughly) it will drop 1m due to gravity.

The same gun will shoot a 0.25g BB will be travelling about 75m/sec. It will also drop 1m in about half a second due to gravity.

The only difference is due to the speed the BB is travelling. So, a 0.2g BB will travel 50m before diving 1m. A 0.25g BB will travel 37m before diving 1m.


All you need to do is use the power calc to work out velocity using a given BB and then type that into the BB drop calc.

I think this ' , ' - ' . ' error is due to some Visual Basic error. I think it hard codes the version of the comma into the exe and you have the problem. Here is a workaround:

Dim STR As String
Dim VALUE As Single
Dim SW As Boolean
SW = True // we assume the input is OK
STR = TextBox1.Text()
// reads the textbox into a string
STR = STR.Replace(".", ",") // replaces all ' . ' with ' , '
If IsNumeric(STR) Then // and check if it produces a correct number
VALUE = STR // if yes then it will be the value which can be used for calculations
ELSE // in case the ' , ' did not produce correct number
STR = STR.Replace(",", ".") // replaces all ' , ' to ' . '
IF IsNumeric(STR) Then
VALUE = STR
ELSE
SW = False // in case no swapping works (due to other characters present) the input is not OK, and cannot be used
END IF
End If

If (SW = TRUE) then // if the value is OK then the calculations can be performed
// ... DO ALL CALCULATIONS WITH THE VALUE ...
End If

An other thing about battery calc:
My charger instruction manual says that I have to multiply the charging time by 1.4 (1700 mAH / 170 mAh = 10 H * 1.4 = 14 H total charging time)

[visionviper]

My charger instruction manual says that I have to multiply the charging time by 1.4

I will add an option to multiply the charging time, will release in v1.3.

As for the "," and "." I wasn't really planning on changing anything code wise becuase I specify in the readme to use a "." and not a "," I may change it so if you do use a "," it will work fine just to do it, but we will see. I have to wait and see how the second half of the semester goes and how work goes, etc.

[Pendra]

I forgot to mention, this version does not work at all for us ' , ' users. It identifies the ' , ' as a character and tells that there is no value in the box. The I used ' . ' and it produced a type mismatch. It only works if you use integer values (like 20 g bullets which need around 100 J to fire).
If you sent me the source code, I will remedy this issue once and for all.

[visionviper]

Like I said, we shall see. If I decide to change it, I will do it. Not becuase I don't think you arn't capable, or that I do not trust you, it is just that I will learn more if I do it myself.

[Pendra]

Ok I mocked this up in about 3 hours, source included. See if you can kill it.

BTW I think Visual Basic sux. I'd rather use Delphi or C++.

So many files..... lol

Eh, it was kind of confusing. It took me awhile to figure out how to use it.

v1.25 released.

Changelog:
v1.25:
-Added the multiplier for the battery calculator
-Improvements to code made

I can't run your calculator cause I don't have a windows computer - so correct me if I'm wrong, but I have a good feature option:

Effective Range:

you enter the ammo type you are using, say, KSC perfect .2g, and the program uses data you will need to collect (im thinking the drag constant) and when given an FPS value gives you a feet-dropped amount for 50 ft, 60ft, 70ft, so on until it has dropped 10 feet. There should be a hopup consideration in this, but since peopel dont know their hopup in units valuable to your program - they test it and enter into the program a distance and an amt of bb drop, so it can detect hopup.
