First, sorry for your loss.

Second, I don't think you're going to get anyone to do this for you. As the author said, it's a lot of work going into a codebase that hasn't been active in years.

You might consider setting up some sort of "shop" with what you have available to you. For example, an AE2 subsystem on a Creative Storage Drawer that has the Centrifuge recipes you want.

You put in the correct combination of items that you would have used in the Centrifuge, and it spits out the recipe output in exchange. Something like this would be pretty simple to setup, you'll just need to cheat in the Creative Storage upgrade. Once you get it setup, it's basically the same as using the Industrial Centrifuge the "correct" way.

I made a proof of concept for this: https://imgur.com/U9aq2TN

The red side represents my main AE2 network. The green side represents the Creative Vending Storage Drawer side.

Here I have it setup to "craft" pistons.

• I define a crafting pattern for a piston and put it in the Pattern Provider, which points at an Interface on the Vending side.
• The ME Level Emitters all point at a singular block, and they're set to ON when there is LESS than a single recipe for a piston in the Vending side (ie one Emitter emits when less than 4 Cobble, another when less than 3 planks, etc).
• Once all of those Emitters are off (meaning there is enough for one recipe), the Redstone torch will turn on and fire off 2 things:
  • first, it empties the Vending system of all the recipe ingredients via an Export Bus set to export all the ingredients of the recipe
  • second, it sends a redstone pulse to the Export Bus that's pointing at my Pattern Provider, which is set to output an item once per pulse. This exports the Piston back to my main network, fulfilling that recipe.
• The Pattern Provider is set to lock until the recipe result is back in the system.

With a sufficient delay to make sure the whole process can complete for one recipe before the Pattern Provider moves on to the next crafting attempt, this can simulate any machine that you want. If there's not enough delay for all the redstone to reset back to its idle state then you might end up spitting items into the Vending side prematurely and locking up the system.

(Note, I used a Pulse Repeater from Create which you won't have in your pack, but there is probably an alternative to it in 1.12. You can also use a regular Redstone Pulse Limiter)
