I liked your idea, and ran with it. I remade it to be extendable and easier to use. You can extend the number of buffers by copy/pasting the bottom part to overlap to as many as you need (down side being to make it work prevents the tracing of the 'V' and 'W' signals). 0eNrtnf1u2zgSwF+lEHDA3p29EIfUV...

An idea from a different angle, what about late game tutorials and blueprints? EX: A tutorial for how to use blueprints as a remote control, and then give them a blueprint for a toggle and remote control. EX: A tutorial for how to make a graph to show what's in the logistic network storage (connecti...

You can use blueprints of combinators as a kind of remote control, So I made a bunch of combinator stuff to make blueprint remotes easy to use. I would like to see what everyone can do with this kind of set up. First the Blueprint Remote (containing ON and OFF signals, all 9 colours, and all 5 ores)...

I created (and remixed other designs into) a digital number display and a letter display that is tileable and compact while being fairly simple to use. The ease of use was key here as I wanted to throw them EVERYWHERE :D Included in the blueprint book is also an example blueprint showing a working e...

TL;DR Adding weather in the game to add some variety to gameplay while being UPS friendly. What ? Every day, have a 1 in 20 chance of getting a 'weather event' which could be one of: Rainy Day, solar panel output is halved and the screen is a bit darker Blood Moon, a wave of biters spawn and attack...

The ability to add a neighbour bonus to radars.
IE: arranging a couple radars next to each other, so that you can adjust the power draw and range based on the neighbour bonus.
