TheCalcMod
TheCalcMod adds a Calc item and a Solar Panel for Forge on Minecraft 1.20.1, aimed at players who want a light technological challenge.
What it does
Calc is the central item of the mod, and its goal is to give a player a technology path to follow. Solar Panel is the other named piece of content, and the two are the core of what the mod offers. Its author describes a short technology challenge that ends in a modest reward, meant to fit a single session rather than a long progression.
Client and server both need the mod, so every player on a server that runs it must install it too. TheCalcMod is published for Forge on 1.20.1 only, and the latest file, 1.0.2, was released on 2026-06-17. The code is not open source, and it is released under All rights reserved. The author credits MCreator as the tool used to build the mod.

Who it’s for: The mod suits players who prefer a short, self-contained technology challenge over a large modpack, and server owners running Forge 1.20.1 who want a small addition. Because it is a client and server mod, the server and every player must install it.
