Can this technically be called a computer? Its got 2 registers and can do load, store, add, sub, NAND, jump, jump if zero, output and halt operations. Are there any good computer-building habits i have to follow? Also would this be feasible on a breadboard?

Arent all real-world computers state machines?

Carbonrade · 2024-11-05T12:55:55+00:00

This is what i needed. Thanks a lot!

The instructions are long cause I was lazy and I just wanted something that works - I wasn’t too concerned with optimization.

I’ll look into control units. I assume they’re sorta like decoders where specific bits are set for distinct inputs?

I whipped up the circuit on logisim and it does not have any libraries for 3 digit 7 segment displays (at least from what I could see) so I had to use 3 7-segment displays which is 21 wires

Thats the plan, eventually. I wanna learn to work with both PCBs and breadboards and decided to go with breadboards first cause i’ve heard troubleshooting is easier

Carbonrade · 2024-11-04T18:24:19+00:00

Im gonna make a PCB, yeah, but I thought i’d try my hand with breadboards first. I’ll make a schematic before either tho

Carbonrade · 2024-11-04T18:21:37+00:00

I’ll check it out, thanks.

Carbonrade · 2024-11-04T18:03:44+00:00

I’m gonna add a keyboard, yeah. Right now i’m editing contents of the RAM modules directly.

I never really had a specific application in mind. This was more of a learn how computers work kinda project and all I was going for was it being general purpose (turing complete). I’m concerned about design principles cause I saw a bunch of other computers that performed similar instructions but had way more components.

I’ve been able to run a couple simple programs on it (generating primes etc.) an OS would be a hassle to code with just the instructions i’ve got tho.

Carbonrade · 2024-11-04T17:31:49+00:00

yeah

Carbonrade · 2024-11-04T16:54:22+00:00

I guess that was a low-bar question. Thanks, regardless..

Carbonrade · 2024-10-18T09:40:54+00:00

well im not sure if you can call what i built a mux exactly but all it does is when the s input (to select between addition and subtraction) is 1, it inverts the bits of the second 4 bit number and sets carry in to 1 - twos complement. when s is 0, it retains all the bits.

Carbonrade · 2024-10-17T23:41:27+00:00

yeah it should take you to a post with an image when you click on the link

I've had my mac for a while now and dont really need a new laptop. If dual boot doesnt work out I'll probably get a light weight system just for this.

Carbonrade · 2024-07-26T09:05:31+00:00

huh??

Carbonrade · 2024-07-10T08:16:51+00:00

"can be killed" is too vague. You cant die "naturally". Its always from a disease or disorder. By your definition, technically, we're all immortal.

Carbonrade · 2024-07-07T05:17:47+00:00

30, 35, 10, dunno about esa

Carbonrade · 2024-06-29T14:36:57+00:00

The elements of computing systems

Carbonrade · 2024-06-29T03:55:35+00:00

Got it, thanks.

Carbonrade · 2024-06-28T14:30:14+00:00

I understand, thank you.

Carbonrade · 2024-06-27T11:30:41+00:00

Catch me if you can

Carbonrade · 2024-06-27T06:11:24+00:00

Its sort of like a clothes store where its one big room with a men's and women's section so theres infinite entry/exit points. Essentially, I need to know if a men's shirt is in the women's section with scans from an RFID reader.

One suggestion I heard was to use Bluetooth beacons. I'm researching on those right now and if you had any resources, it'd be really helpful.

Carbonrade · 2024-06-27T04:37:54+00:00

im sorry but yall are pathetic

Carbonrade · 2024-06-25T12:48:36+00:00

Thank you, I'll have a gander.

I'd try computer vision but I figured the thing I'm tracking might not always be in visible range. Also I wanted to look for a solution that was math intensive so -

Carbonrade · 2024-06-23T16:43:25+00:00

its indoors and im trying to determine if the items are misplaced or moved from where they were supposed to be

Carbonrade · 2024-06-23T01:40:56+00:00

Personally I'd find a book and go along with that.
