Free electronics simulation software?

[ZedNova]

I've recently been building electronic components in the powder toy. Unfortunately it is severely limited, building a complex processor requires overlapping circuitry, something this just can't do. I'm limited to building single bit components. And don't even get me started on building interfaces for these.

Is there any software out there where i can:

1) Build my own processor and data storage devices.

2) Create displays and peripherals.

3) Save each piece individually and combine them together at a later time?

Any suggestions would be awesome, thanks

Minecraft? LOL, j/k.

Powdertoy is awesome thing, I've built many contraptions there.

I needed the same thing as you few years ago and I couldn't find anything for free so I gave up on the whole idea.

Minecraft and a world editor would best suit your needs. But its does cost. What your are asking for is a lot... If you want anything you would need to pay something like £20 to get something like you are asking.

Well, i'm willing to pay. But is there any software that does this?

I already have MC, and that's still limited. An ALU would take up several chunks.

Why don't you pick one of these

ive never encountered a circuit simulator that worked better than just building the damn thing and putting a multimeter and oscope to it.

ive tried LTspice, but didnt really do anything useful with it. heres some tutorials:

though its mostly for analog stuff.

Ameteur engineers don't often have the tools and the work space and the parts to do this.

All I've got is a soldering iron, one spool of wire, and a couple LEDs. I made a light up shirt once

i just got me a hot air reflow station, i feel so awesome.

It's expensive, but you could try building one IRL.

In semirelated news, The Powder Toy is addicting.
