Automation Help

[DiamondSentinel]

I'm using MineFactory Reloaded in conjuncture with Steve's Minecarts 2, trying to automate a good tree farm. This is early stage, before I have a centralized power grid, and I want to only activate my engines once the composter is full, but keep supplying energy until it is empty, then shut off. Do you know how I could manage this?
Oh, and don't hate on me, but I'm using Tekkit, but the Tekkit forum is crap and this is my old map before I was able to run any FTB packs.

Buildcraft gates. Bit expensive to make though(Need lasers, assembly table, and a good bit of power.)

Well, I thought about that, but I couldn't think of how to make it continue to supply a redstone signal from the time it fills to the time it is empty.

You could do something like this.
Buildcraft gate->toggle latch->Engine. That way, every time the gate triggers, it'll trigger the engine on or off, but still provide a steady redstone signal when needed. Alternatively, you could just use timer->toggle latch->engine. That is cheaper, but you have to do a little experimentation to find the best timing for the timer.
This is assuming you have redpower or project red.

Yeah, I was thinking the timer would work, but that would take unnecessary time to set up. I'll try the gate idea. Thanks! So much more helpful than tekkit forums...

first: iron OR gate with red and blue wire next to the composter with:
inventory full -> blue pipe signal
inventory empty -> red pipe signal.
second: diamond Or gate with all four wires next to the engine with:
red pipe signal -> green pipe signal
blue pipe signal -> yellow pipe signal
NO green signal-> blue signal
NO yellow signal -> red signal
yellow signal-> redstone signal
third: pipes between those two: red and blue pipe wire

note: You have to add the pipe wires first. You can only set pipe wire conditions when pipe wires are installed.

Ah, thanks. I knew that it would be some way I could do it with buildcraft gates.
