That's basically fgcapo and my design with two major shortcomings: 1) no filter against negative signals 2) has to be supplied with the negative number for filtering With a static cc already containing -2^31 like yours, fgcapo's can be reduced to 2 combinators including an input filter. Ah I see, t...

Unless I'm missing a trick here, and if you are happy with only positive outputs, you can do this with 2 combinators and an electric pole. Factorio_filter01.jpg The left combinator contains item inputs with amounts. The right combinator contains item(s) you want filter with the amount set to a large...

I haven't seen this before so sorry if it is already known. I came up with a pseudo-method of monitoring a heat exchanger to power inserters without complex circuitry or timers etc. Basically you connect 1 tank to 1 of the Heat Exchangers in your power plant, add a pump to the output and then connec...
