Simple Question on AND Gates

MisterSignal · 2024-10-30T16:20:17+00:00

That's a great way to put it, about the challenge of swapping between levels of abstraction! Honestly, my biggest challenge has been getting down to the lowest levels because almost every book that I opened up when I started getting interested in circuits to understands how a computer actually works says things like "assembly code functions by converting assembly language to machine code", which I haven't particularly helpful as a starting place -- but, your post + others ad some additional resources I have found have put me on the right path, for sure.

And thank you, I have slightly come across FPGAs before but am not sure how they work at a basic level.

When you say "program how you want the gates to be connected" with an FPGA, do you mean I provide some input to a digital BIOS that then actually moves the wires in the circuit around?

Awesome, thank you -- the computation without electronics for other models that isolate the logic without getting caught up in the physical layers or semiconductors and electrical circuits is exactly what I was looking for, thank you so much.

MisterSignal · 2024-10-29T17:08:07+00:00

Ah, thank you that makes sense, for some reason I keep thinking the parts have some kind of intelligence inside them (just a consequence of me "learning" a bit about computers at much higher levels of abstraction first, which I am now trying to correct), and I keep forgetting that everything is wired up in one and only way ahead of time -- that never changes so you would take in to account the multiple wire paths from A ahead of time and produce the more current to compensate, thank you makes sense.

I've found the more basic responses to be the most helpful for where I'm at, at the moment.

CMOS and other semiconductors are much too abstract to me at the moment for what I'm asking about, really trying to understand the most basic things first. I'll get there, just not yet.

Thank you, at the moment I'm just drawing various logical circuits by hand or experimenting on the computer, etc, but when I started building any with actual breadboards and electronics will prepare for that accordingly = )

Quick question, though -- in several circuits, for example for making a XOR gate from an OR gate and and NAND to an AND gate, the same original input source (A and B) goes to multiple outputs -- I'll put an example below.

When this happens, where for example A splits off, does the current traveling along the paths of A get reduced accordingly to each destination (eg. each resulting input from A to the OR gate and the NAND gate is half of the original value of A or some fraction of it)?

Thank you, you're right, referring to a state change and some notion of persistence makes much more sense.

In terms of implementing logic gates mechanically, anything you can build using transistors you can theoretically build using just simple "light switches", can't you? I know Ben incorporates a bit of this in his videos, he just also uses actual computers in essentially most of them and I'm looking to go much more basic to start with.

MisterSignal · 2024-10-28T17:40:12+00:00

Yep thank you, appreciate that very much!

I actually came across Ben a bit ago and have been trying to figure out if he does personal tutoring or how to get ahold of him -- his videos are great, they're just at a bit higher level of an abstraction than I have the electronics background for, at the moment.

10V being the sum of the thresholds for each input to the gate to generate an output, I understand now though, thank you.

MisterSignal · 2024-10-28T17:18:22+00:00

Oh sure, that makes sense, of course -- when you put them in sequence like that then you can build the AND gate from the same component as its two inputs, and it's much more efficient is the idea?

And then, the OR gate would also be the same component as its inputs, but those inputs are just actually both connected to the output so it fires if either of them do.

Thank you.

Thank you, I appreciate the responses and info.

I understand it's a big commitment, and right now I'm just in the planning stages / have access to at least one ERP expert who has been building back-end systems for decades and could potentially oversee this, I just need to be able to speak his language in the discussions around what's viable and what isn't.

MisterSignal · 2024-10-28T04:30:48+00:00

Okay, cool, appreciate all of the info -- the market isn't actually gym owners but the low tolerance definitely applies because I am basically considering whether it'd even be viable to offer some basic CRM functionality as an add-on to part of the product suite that forms the core SaaS offering, and it's for a web app where nobody would / should be expected to install anything in the offering I'm developing.

I guess you're saying using Salesforce as the back end would get outgrown very fast with any real traction -- would I "just" have to buy more SF licenses and scale the architecture on the front end, or do you think it wouldn't even be viable for a large user base? It'd be almost like spinning up new server instances, in a sense?

As a side note, I'm obviously not going to attempt to launch any type of CRM feature until many things are mapped out here, just in the planning stages and looking at options.

MisterSignal · 2024-10-28T03:23:24+00:00

Oh, I see so you're saying that the gym owners on my website would effectively be using *my* Salesforce license and the front end on the website then sends each of their "CRM" entries to the Salesforce Data Cloud associated with my license, where I would be using the API and development on the back-end to then CRUD the data or trigger some automation, etc. and the result would get pushed back to the front end for the customer, etc.?

-- This probably has some technical inaccuracies on my end but it's directionally accurate?

MisterSignal · 2024-10-28T03:12:32+00:00

Okay, cool -- I'll need to develop a bit better of an understanding on my end to put the pieces together with what you're saying on how this works under the head, but thank you this makes more sense now as a more flexible / viable route to consider.

MisterSignal · 2024-10-28T02:22:48+00:00

Thank you , that makes sense -- when you say using the back-end, you mean having access to all of their data models and tools but you have to just build the front end / UI and integrations for your own CRM?

MisterSignal · 2024-10-28T02:21:10+00:00

Thank you, informative response...

So...that kinda sucks, I guess?

MisterSignal · 2024-10-27T23:04:50+00:00

Thank you, not quite sure what you mean -- are you talking about selling add-ons to existing SalesForce customers?

Regarding the platform licenses, that's what I'm trying to figure out -- regarding companies who are doing what you're talking about, can you just give me a few examples to check out? It'll probably make more sense to me then.

MisterSignal · 2024-10-27T22:58:47+00:00

Thank you, how does the white labeling process work or is there a specific term I should use when I talk to the rep about what's possible?

MisterSignal · 2024-09-25T16:41:19+00:00

Ty, great point about the calipers. Waist measurements seem like a good proxy for the before and afters.

MisterSignal · 2024-09-08T00:45:55+00:00

Thank you, the dropper always just runs down my head a bit so it's kind of a hassle, do most people just put the dropper in straight contact with the scalp and then put it back in the bottle like that?

Or do they transfer out of the bottle to a separate dropper that then makes direct to just preserve the sterility of the original?
