This is the first time I've dabbled with computer circuitry, so I hope you enjoy. This is a summation or addition calculator, and can handle 16-bit numbers.

    @Pharaoh Heh... the beauty of this magnificent beast. The thing is that this is understandable for me is that it's analogue. If it was fully programmed (Which I will never know how to do XD) then this would be a clusterflock of blips and bloops that'd melt my brain. I'm glad that this got onto the FP. FAVOURITE!!!! YEEAAAAH!

    @TD23ASUS, yeah, lol, it was the same for me. I just looked at the Wikipedia page and I realized that I could just replicate it with gates. I just kinda scrapped this together xD

    I like this save because for me all that advanced electronics confuses me, but this (apart from the overflow, argh too many colours) actually taught me something: that it is possible to make a simple calculator with a little sweat, a lot of blood, some shambam and simple ARAY electronics. Since I've done something very similar this actually is like the next step for me. Thanks. :)

    @Schmolendevice, or we can even use CUDA/OpenCL for fast frameskipping (like 10 frames in 1)

    @Schmolendevice, subpixels? Like a second particle array on the screen? Then, we need to go deeper (to the source code :D ), and make a "SPECIAL ELECTRONICS MULTITHREAD PowderTOY" :DDD

    @Pharaoh Yeah, yesterday I got bored and quickly mashed together this private save for folks to feast their eyes on; id:1778279. This is good work because certainly prior to learning about FILT and sub-frame timing I couldn't have gotten my adders as fast and compact as yours. But indeed there is still some ripple carry latency in this design. Pretty much with the current tech coming around you'd be quite capable of doing 40 to 100 additions in the time it takes normal electronics to propagate.

    @Schmolendevice, thanks for clearing that up. @Sourec, lol, yeah some call it an adder, some call it a summer.

    You know, I thought you made a replication of something called "Summer" in 16 bit... I actually thought of the season Summer!

    Nice work on this save. @ErgOnWire By the way, in the case that the devs say again and again that increasing the screen size be useless thanks to the fact that 'sub-pixels' simply don't exist, 64 bit CPUs would in fact be possible with the current FILT technology. And yeah with LBPHacker and subframe timing, subframe timing will allow for very high computing speeds.. Just keep waiting for a 16 bit instruction per frame computer to come out.

    Nice job on that adder, maybe 16-bit ALU next time? :D BTW if we could make the PT simulation bigger, some more advanced electronics will be possible to make. Like a 64 bit CPU with LED colour display :DD
