Query: How do you detect the level of power a energy cell is holding?

[OrsonThinks&Talks]

In the FTB Monster pack I have tried buildcraft gates but they seem to no longer interact with TE energy cells and have tested other means such as computercraft peripherals but this was Waaaay to complicated for it to be practical. Does anyone know of a way to detect RF power at all? it would be extremely helpful to my current project

I believe if you put a comparator next to an energy cell, and output the energy cell into the comparator, the comparator will give a redstone signal with a strength which is equal to how full the cell is.
so a full cell would give a redstone signal of 15 (or whatever it is) and a cell with a bit of energy would give a redstone signal of 1

Oh cool lol, thats rather simple, I just through the hassle of converting the RF to EU and reading that lol thanks!

IIRC its slightly more complicated than that. Comparitors have two options, compare and subtract (or some such)

Both require two inputs, with the output depending on which option.

With compare, an output is only produced if one signal is greater than the other.
With subtract, an output is produced with a signal strength as the difference of the two inputs.

To the best of my recollection anyway

Someone mentioned some item that basically did what Nuclear Control used to do for TE cells. Just cant remember which mod/item it was now...

You don't actually need a redstone input to the comparator for this. Here's how to do it with a PRC.

I think I figured out which item it was. Its the Power Monitor from EnderIO, but sadly it doesn't quite do what I thought. Instead it monitors powerlevels of all connected Capacitor banks and can then be used exactly like a Nuclear Control "Range Finder" to output redstone signal based on energy levels. So it is entirely possible to use, you just need to exchange your Energy cells with Capacitor banks.

Direwolf20 also built something to handle this when he was building his nether star generator. (27:02 is where he starts talking about comparators)

A comparator would work.

Compare with a lever + 1 redstone dust. I use that to save fuel with my set up, as it'll open/block some liquid redstone from falling down and turning on force engines.

Unfortunatly false A comparator is indeed as easy as putting it next to a cell and it will output a signal from 0 (empty) to 15(full). No additional redstone needed.

Jadedcats video available on the reddit link Omgetron posted shows this perfectly working in action incase you need proof

Thanks kindly for the clarification.

and CC testing doesn't need to be complicated the code is quite straightforward
