Make the most of your accumulators by using an automated power switch!
Video presentation/instructions can be found here: https://youtu.be/q6PQPRBlNI8
decent description/instructions/pics coming soon... for now here's a hasty description: (sorry!)
Most of these blueprints have two constant combinators with which you can set when to toggle backup power.
When accumulator power goes below the "L" parameter, backup power is turned on. Then,
when accumulator power goes above the "H" parameter, backup power is turned off.
"L" and "H" are defined in the two constant combinators that say "LO" and "HI" respectively.
By default, all blueprints are set to start bkp power at 20% accu. charge, and stop it at 100%.
The last two blueprints (compact and barebones) have to be set up manually. To do so, put the low threshold in the decider combinator (20 by default) and the high threshold in the arithmetic combinator. To calculate this number, do (the percent of charge you want - low threshold) * -1.
for example, the default value is (100 - 20) * -1 = -80
You can check accumulator power as a percentage by hovering over the power pole with a green wire.
When you see a copper wire in the blueprint icons, that means you'll have to disconnect the poles from each other manually. (they connect automatically when placed by bots, but aren't supposed to be connected)
also there's a green light for when accu. are at above 99% charge and a red light for when backup power is on.
a more detailed tutorial with more information about the operation of these things is due within 24 hours... probably
EDIT: 24 hours my ass... i'm working on a decent tutorial, but i also had to fend off a bee invasion so hang on <3
