I made a mod using AI which lets me build electronic circuits using blocks and then simulate the circuits using ngspice.
I know that a lot of people don't like the use of AI, but I have zero prior experience with Java and Minecraft modding and wanted to make something fun for myself.
I am sharing it because I searched for this kind of mod and didn't find anything, so I thought about trying to do it myself.
The mod is still in VERY early development!
