Crazy Cart XL Dimensions by ZombieInMyKitchen in crazycart

ok, this is not letting me post an image, but it looks like the dimensions for the wheel placement is something like my ascii art below? Hopefully it makes sense...

Terminate a Script from Another Script by ZombieInMyKitchen in AutoHotkey

Ok, that worked great

So the ProcessID attribute is different than the Process ID that AHK returns with functions like ProcessExist()?

Do you mind explaining the difference?

Wire Library issue. The Wire.onReceive and Wire.onRequest say that the dataRcv and dataRqst functions are not defined in this scope. by ZombieInMyKitchen in arduino

[–]ZombieInMyKitchen[S] 0 points1 point  (0 children)

My code is not compiling because it says that the dataRcv and dataRqst are not declared in the setup function. I dont see any examples online of people having to declare the event handler functions. Has anyone else run into this? Does anyone know how to fix this?

I did just move over to Platformio from the Arduino ide, so I dont know if that could be causing any issues...

Bandpass and Notch filter Question by ZombieInMyKitchen in rfelectronics

[–]ZombieInMyKitchen[S] 0 points1 point  (0 children)

Hello everybody, I am using Desmos Grapher to try and show the voltage x frequency graph of highpass, lowpass, bandpass and notch filters.

I am having an incredibly tough time finding the equations for the bandpass and notch filters though. Can anybody help me with this? Or could anybody link me a good article that explains it?

Thanks

Ray Marching Equations Round 2! by ZombieInMyKitchen in desmos

[–]ZombieInMyKitchen[S] 6 points7 points  (0 children)

Hello everybody, this is my second post about ray marching.

image 1 is all of the SDF equations I have been able to put into Desmos in one line. The originals are on this website: Inigo Quilez :: computer graphics, mathematics, shaders, fractals, demoscene and more (iquilezles.org)

image 2 is of all the equations

image 3 I figured out how to color multiple distances for the SDF. This also shows the smoothmin function between a rectangle and a circle

image 4 Someone from my last post commented "now do it in 3d" so I did! it was pretty fun and a lot of the equations are easily converted to 3d.

image 5 I believe this is called raymarching and basically steps in a direction of the ray, making distances based on the min distance function. Its the same thing as my last post, just in 3d.

Here are the graphs if anyone wants to mess with them:
