Anyone with good redpower knowledge. I need your help.

Ok, so I have forestry farms and I want to automate them. I feel that redpower can do that. My idea is something like this.

Engines are off for 20 mins so farm can grow, then at twenty minutes the engines run for 5 mins, and after that it reverts back to the 20 min countdown. How can you do this without state cells (Because in the version of Tekkit I'm running it doesn't have those)?

A redpower sequencer should be able to do the job just fine.

Toggle latch, one timer on each side with their outputs wired to the toggle input. Set one timer to 5 minutes, the other to 20.

Only one timer is active at a time and when it finishes it's countdown it flips the toggle, turning itself off and the other timer on. Just feed off whatever side gives you the time you want.

You could use timers, sequencers, and I guess you could use a computercraft computer(But that'd be a little bit harder to do).

I could probably do the computercraft script, but it'd be easier if you just went with a redpower thing.

Left timer is your 5 minute timer, right timer is the 20 minute timer.

White cable pulses whenever there is a change. Magenta is on for 20 minutes and off for 5. Lime is on for 5 minutes and off for 20.
