Making electrical engineering less tedious, but now using InForm.

The electrical code requires that conductors be sized so that there is no more than 3% voltage drop from the nominal voltage at the farthest point of the circuit. As an experiment, I wrote a program using InForm to calculate voltage drops in circuits. It can analyze a single load at the end of a circuit or a series of loads along a circuit (think streetlights.) 

Doing the actual engineering is interactive, a combination of engineering science and economic considerations. If the voltage drop is too high, which parts of the circuit do you select to upsize the conductors, and by how much?

This is not finished, I have some thoughts for more features to add later. But the program works as it stands now.

Comments and suggestions are welcome.

Hi,

Find attached the source to another keymapper utility.

Although it works in the QB64 IDE it is not a Windows utility -- use PowerToys instead.

This utility works for Ascii and Extended Ascii mapping with values of each being 1-255..

Also lists ascii chart and mapping charts. Some functions detect text keyboard keys.

Erik.

Hey folks,

So I have finally managed to get a modern laptop and can now run the latest version of QB64! 

I have resumed updating my libraries, demos and games and will of course need help/pointers and feedback...i'm sure you guys will be as congenial as ever though!

Thanks and happy coding!

I needed a little function for convert bytes into KB,MB,GB,TB,PB.
Here she is..

Hi all, new to the forum, new to QB64, but have done some coding in QB.

I have a general question on the math capabilities available.  I am tied down rright now to a 32-bit Win 11 machine.  I would like to do some math operations using 64-bit integers.  Will QB 64 be able to give me the full precision of the 64-bits?  I realize that I will lose speed on the thunking from 32 to 64 bits, but I can always recompile and run on a 64-bit machine when I get access to one.

I want to start coding again since I have some forced free time so expect some more general under-the-hood type questions.

Hello All,

This is my take on the single player logic puzzle Twizzle.

Hi,
I have several programs that call python programs, the python program writes its results to disk and then the basic reads the results and uses them.  (some of the python libraries are very useful). In particular I am using pyephem, a library that calculates astronomical date on stars and planets.  
Is there a way to do this without the intermediate step of writing the information to disk?  Can the output of an external program be ported directly into a basic array or other structure?

Before I go off and try this.  I will ask it here to see if "Yes you can and it would work".  Generally the best idea's stay private and nobody benefits.  I hate that approach.

What i do now: I use a program called Total Commander if you have used Norton commander in the past you know what I mean.  It's great for finding all the filenames in a directory (sub-directories) or drive.  From the total list show I can select via (numpad +) and subset based on a select pattern ie: *.jpg   I can clip and drop that list into another program for processing.  In short I have a list dropped into a program.

Is it possible: Using a console window in qb64pe to find all those JPG's list them with paths in the window, select them with ctrl-a and drop them into the program.  Using it this way, I save lot's of clicks and steps.

I have done some amazing things I never did with qb45 using qb64pe (and extensions).  If it's possible I have another sharp tool for the my toy box.  If I figured wrong.  Got an idea ?

Thanks

PS.
I never thought of this forum or users to be like Reddit.  Everyone here is both helpful and smart as fuck.

Deep in the African jungle, high in his tree-top lab, NakedApe has been hard at work on his next space game. This is my first attempt at 3D - well, 3D Lite for the mathematically challenged anyway. I tried to keep this fast-paced since attention spans are short. This has one-handed mode for easier play too. Thanks to bplus for help with circle aspects, SierraKen for the globe routine and Steve for bits of code off the forum.  This looked best at higher rez, so I made it 1920x1080.

It's a work in progress and I plan to take it a little further, so feel free to tell me what it's missing or not. Thanks for playing.
Ted

I asked ChatGPT to make me a Pringle. So tinkering around with it I made this animation. 

Screen _NewImage(600, 600, 32)

CENTERX = 300

CENTERY = 300

' Pringle parameters

SIZE = 300

STP = 1

Const ZSCALE = 30 ' Controls how much "curve" there is

num = 20

dir = 20

t = 4



Do

    If num > 3000 Then

        dir = -20

    End If

    If num < -3000 Then

        dir = 20

    End If

    num = num + dir * t

    For x! = -SIZE To SIZE Step STP

        For y! = -SIZE To SIZE Step STP

            ' Hyperbolic paraboloid formula: z = (x^2 - y^2) / scale

            z! = ((x! ^ 2) - (y! ^ 2)) / (SIZE * ZSCALE)



            ' Project to screen (top-down view with z as shading)

            screenX = CENTERX + x!

            screenY = CENTERY + y!



            ' Shade based on height (z)

            shade = 128 + z! * num

            If shade < 0 Then shade = 0

            If shade > 255 Then shade = 255



            PSet (screenX, screenY), _RGB(shade, shade, 255 - shade)

        Next

    Next
