A fun little project that helped me stay awake on a particularly boring uni lecture. 20230826: Added a resettable decimal counter.

    I'm new to these kinds of stuff (electronics) in TPT and only uploaded 3 calculators that use falling conductive powders/liquids to add 2 numbers. The problem is that the Display circuit is huge and takes a lot of space. I can only make LCRY 7-segment display. Can anyone tell me how to make these super compact FILT type displays so that I can improve my calculator? BTW +1

    I won't answer this question in a comment section, bug me on irc or discord.

    I thought I would keep it simple and follow a simple path, but move gradually towards using and making more FILT-"friendly" stuff. Is there a way for me to make a decoder that is more efficient than the "demultiplexers" I used (in place of more recognizable decoder modules)? Now that I think about it, the ones I made are a bit like "pseudo" decoders, since they function like addressers, according to you.

    @LBPHacker, Part of the reason I refer to it as BIN>DEC is because the position of the SPRK (output or input) represents either a Binary or Decimal value. I figured it was common practice to say it like that, because users like Darkn and arK have done similar things. They didn't use much FILT logic, and stuck with non-subframe and SPRK-based logic with conductors and semi-conductors.

    Sure, that would be whatever-to-decimal. You need something better for anything more than 8 bits though. And nope, I'm not making a tutorial on CPUs, there are plenty of those on the internet.

    What if the position of the output simply represents a decimal? Instead of a line of INST, it could just be FILT with a Ctype value of a BCD on it

    LBPHacker: Could you make a tutorial for CPUs? If yes it would be helpful!

    It's decimal if it represents decimal digits in some form or another. In the context of TPT, this usually means binary-coded decimal or like, 10-level piston accumulators.

    That makes more sense. Would you consider it Decimal if you encoded it onto a px. or BRAY or FILT as the Ctype value? What more is there to it?
