I will be updating the mod slowly due to the fact that LimpCraft2 and LimpCore are the primary focus right now.

That being said, I want to get a working basic calculator done in the next week or two (I am known for going on month long hiatuses, so if I disappear it doesn't mean it is stopped in development).

Currently, it is in a very unplayable state. I have the item (no recipe) in the creative tab, and the framework for the GUI popping up.

The GUI has the basic calculator on the left. On the right are 5 slots, the Calculation output below them, and a battery level split in 10 percents to the right of that, showing a gradient when the internal battery is full of charge.

[Not implemented are as follows]

The five gui slots add 4 functions and power to the calculator.

The first slot, a power slot, is what recharges the battery. It gains 10% internal battery each redstone it uses.

The second slot, a battery slot, temporarily holds glowstone. When I make a chargeable battery, it will add more power storage for the calculator to recharge with redstone / use to power the calculator. So far, at least a double battery is planned, so you can calculate twice as long.

The third slot, a solar panel slot, will allow you to recharge the internal battery to full without the use of redstone.

The fourth slot, a clock slot, will show a digital clock version of the ingame time!

The final slot, a mirror slot, will show your player's reflection (aka, like in your regular inventory, the player model) for aesthetics.
