WIP Furnace contraption:

When input ingredients are picked up from belt there's always a space left, so why not use that space for output? ;)

This contraption is designed so that the space left from removing an item is consumed by the output ...

Nice thing is that once you set up the packets and let them onto the belt, you don't need to make everywhere those "signals", they will simply keep their distance that was set up by combinatorics that let them into the system. Problem is if belt is not straight and belt sides will not be ...

Improved multiplexer design:

Much more compact now. 8-)

Multiplexer is nice and so far have trouble replicating it (logic selecting one belt from two). Can you post some infor on how to set combinators?
Sure thing. The idea is to have a memory to remember the last ...

the memory cell keeps count from the inserters.
A solution based on counts of items on belts is not what I'm looking for here.

That's a "whole belt" kinda solution. I'm looking for finer grained control of what actually happens on the belt. Like for example:

Contraption #3: 4-to-1 Belt ...

memory cells are also good for keeping track/controlling what and how much of something is on a belt. ;)
Yeah that's another option.

I wanted a combinator free solution. Otherwise each segment of 10~11 tile belt would need a set of combinators. My solution only requires some green wire. ;)

The ...

Contraption #1: Rail Signal Like behavior for belts.

My first step into making a circuit controlled belt system.

The conveyor belt system in Factorio is hard to beat in it's efficiency at controlling supply VS demand. Belts are basically a circuit network of their own. Not only they move items ...

So I've started some research into working with belts in my circuit creations.

Along the way I noticed that the output of a belt in "Read contents" and "Hold" mode is not what I expected. I was hoping that on a full belt the value read would be constant, it is not.

I made a little demo video ...

I like this :)

This was more of a proof-of-concept of some ideas I had. It seems that Factorio's circuit network is somewhat suitable implementing some kind of SIMD architecture. The parallelism happens across the different signals.

But ...

So I decided to make a text console using the above display:
Text is typed from left to right
When "cursor" reaches end of line, the entire display is scrolled upward to make room for more text
Replaceable character map (stored as constant combinators)

I tried working with all signals ...

The display part might also be interesting on it's own. Each lamp is controllable by a single bit of a signal. It's seems scalable to many more signals without increasing the amount of combinators too much. Certainly something I will investigate in the future. :)
Expanded the display build to a ...

I wondered if it was possible to extend the shift register idea to beyond 32 bits. So I came up with this:
