Using circuit simulator (can find it on itch.io) and recently built an 8bit adder as you can see below.

Pins on left are IN and pins on right are OUT.

Just wanted to run it by some of you because 1. circuit simulator is fucking cool, 2. I'm not sure if I got the basics correct.

I attached an imagine of the 8bit adder along with the subcircuits if that interests you.

It grinds my gears to no end as to how insanely BAD most Electrical engineering software is. Lets start with Tina. A circuit simulator. A few versions ago it was rather good but now it feel like its built upon more legacy crap than fucking Windows! This causes it to have memory access violations and crashes even when you look at it from an odd angle.
On topic of circuit simulation. LT-Spice! It has less errors than Tina but is impossible to use without being lobotomized first. Who the FUCK decided it was a good idea to reinvent keyboard shortcuts by movin all of them to the F-row at the top of the keyboard. Also there is no option to delete a component. YOU NEED TO USE CUT IN ORDER TO REMOVE IT!
And at last Altium Designer for Layouting and Schematics. Whose license costs 9 grand. No one outside of some companies will buy this because of the price. Altium realized this and made two watered down versions of it. Which dont really get updates anymore. (last one was in 2018) So they essentially made a cash grab from people who cant afford their actual product. There also exist other (and a lot cheaper) products than what Altium offers. The problem is that they dont work well with interoperability. Schematics drawn in one program will look distorted in another or not import at all. And since Altium is the industry standard you got yourself this nice steaming soup of impossible collaboration. Its kinda like Adobe being absolute shit at progressing their software just because they got no competition. Or rather they do but the industry wont switch cause adobe is so engraved into it.

Itd be cool if we could get something like Schenzen.Io going, but you build the chips from the gates up
Maybe package them into modular units, and connect those at a higher level or abstraction, ad infinitum.

Then add access to virtual LCD output, and other peripherals, or even map output to real hardware, essentially letting you build near bare-metal virtual machines.

Dont know about that last part, but the closest I've seen to the rest is circuit simulator and again, schenzen.

On the machine learning front I figured out I need about ten times as many training samples as validation samples, or vice versa. I'll have to check my notes. Explains why I could get training loss below 2.11

Also, I'm looking at grouping digits, and trying different representations. I'm looking at the hidden variables for primorials to see what that reveals. And I realized because of the amount of configurations and training that I want to do, even a personally built cloud isnt going to be sufficient. I'm gonna have to rent someone else's hardware and run it "in duh cloud."

Any good providers that are ridiculously upfront for beginners to get started with? Namely something cheapish.
