I was only at the beginning stages of an EE degree when I decided to switch back to IT, so this question might be totally off but: I don't see how the switching of the logic signals are 'built' using sine waves? I know that you can make a square wave using sign waves, but in the case of the logic signals, they aren't just simple square waves , but a DC voltage at either 0 volts or 5 volts. Obviously you know more than me in this arena, so what am I not seeing?

Thirty years ago I was in a computer architecture class listening to a lecture about Andrew Tanenbaum and his MIC machine. (Sienna College, a liberal arts type college) I thought it was cool and decided to write a simulator in Turbo Pascal. I worked real nice with lots of blinky lights and traces lighting up when active. The Prof was so impressed he used it for a few in his architecture classes. Each student received a floppy disk with my simulator on it. I learned sooooooooo much while writing that program.

Of course it can be done, but you might actually need a static core, because you might actually not be able to clock a non static IC slow enough for both the IC to work and not well, have it compatible with the RF limitations of the breadboard and wires going everywhere. I'm guessing that you would be severely pushing it if you went anywhere near 1 MHz, but I might be wrong ;P

@@eiryna4560 SRAM is Static Random Access Memory. It is an array of flip-flop circuits that hold contents as long as power is applied. They are simpler to use because, unlike Dynamic RAM (DRAM), they don't need a periodic "refresh" procedure that reads and re-writes the data to keep data (charge state) from leaking away. This requires circuitry and timing that add to the complexity of the project. During the refresh. the memory is "off the bus", not available to the CPU
@MrGoatflakes 2 жыл бұрын
@@rickperez8044 having the computer static is more than that though. The entire thing needs to be stable when you stop the clock. The late 1970s/early 80s NMOS 8 bit MPU chips used in the 8 bit home micros usually weren't static for some reason, their CMOS replacements/equivalents that came out in the late 80s/early 90s usually were. But the industry had moved on to 16 and 32 chips by that stage. Most of which weren't static not least of which because they typically used DRAM so they could have more memory. The only home computer that used them that I am aware of was the Apple IIGS, a phenomenal machine that used the WDC 65816, a static 6502 based hybrid 8/16 bit architecture. But as good as it was, it still probably wasn't as good as the Amiga for instance, (Motorola 68000 based), and I don't believe the IIGS was static as a system either, because I believed it used DRAM. It's possible to create a static system with DRAM, but you would then need seperate refresh circuitry and clock and probably buffering between the memory and CPU bus, and that would be stretching the definition somewhat.

I've also changed the graphics card once because they go through the most abuse in a modern home table top and sometimes they are just manufactured to fail. Hard drives are mechanical things so it is clear that they can't last forever, but the main processor (8 cores at 3,6 Ghz) and the memory (16 GB DRAM) are just working fine.

The breadboard quality really is a huge deal. Last year I had to assemble my group's course conclusion project and I had to use our breadboards to make a functioning prototype to test before getting a PCB. While using only one breadboard it all went well, but when I started to put components on the other, which was from a different manufacturer, it all went downhill and would only work if I aplied pressure do some connections. After that I got really frustrated and just sent my friend a scheme for the circuit so he could draw it on a fenolite copper plate and I could corrode it. Luckilly the design didnt have any problem with the basic circuit.

It always is with tech videos. But never think you have to keep up. Take your time, they are videos that are available for a long time. The great thing about youtube education is that you can take as long as you need. I tell people who ask me how to learn this stuff to set out 6 continuous hours of learning a week. It is not a lot, but a good 6 hours gets you a long way through the learning process. Some people can keep up with videos like this with 6 hours, some people need more. It doesn't matter, all that matters is you learn what you want to learn and learning becomes a hobby. Eater is a pretty good resource as he goes slow enough but not too slow. And explains everything in detail. Once you know what you didn't know, you can always look up what you need to know on google. Just take you time and there is no reason to keep up with the videos as they come out. Not putting pressure on yourself helps make learning fun again.

There is a known amount of time that each instruction takes, so the LCD drivers just 'spin their wheels' for a few miliseconds to let the LCD catch up. Actually reading the LCD busy flag will end up wasting the same amount of time. Also, by wiring the LCD in 4 bit mode, and leaving the LCD R/W hard wired low (write), only 6 wires are needed in the interface.

Waitaminute. Is that square wave literally just a graph of the intensity of each frequency!? So he uses all odd frequencies so that the plot alternates between high and low? If that's correct then wow, just blew my mind.

@scharkalvin 4 жыл бұрын
@@Breakfast_of_Champions Sitting in a loop reading the busy flag and waiting for it to become false is exactly the same as just waiting a number of MS, the cpu does nothing else during that time. It's not possible to attach an interrupt to the LCD, so there isn't any other choice but to keep reading the status reg and testing the busy flag. You could put some other task inside of the wait loop, such as reading switches, but being that the purpose was to update the LCD things get tricky. Since the Arduino doesn't support threads, a multi task solution to the problem isn't readily possible. Best to just live with the wait loop, sorry BJ.

This is a great idea. I've always figured there were ways to use that "old tech" to make new things. And while I love the idea of a large breadboard project to wrap your head around how a complicated circuit might work, I've got an old Atari 800 that's just begging to be turned into something useful. Really like your walkthrough of breadboard construction. Its good to know why my cheap breadboards can be frustrating. I really liked your analysis of breadboards and "high frequency". I don't think I've ever had anyone walk me through the *WHY* things can fail on a breadboard. It likely explains the need for an "antenna" on a project I worked on once in a college lab. Thing did not work unless we had a stray wire hanging out of the thing. Stray wire added, problem solved. We didn't have the tools to figure it out, and my lab partner was one who didn't like moving forward without figuring those things out. Unfortunately, I saw no real way to fix it (well, the thing to do was to rip it up and make it look as neat as what you have here... but no one wants to do that in a college lab...)

After watching your videos first intermittently, and then splurging the whole 6502 project videos, I got so excited about electronics and breadboards and signal processing and timings and clock signals etc that I feel like a little kid again. I've also been wanting to really understand all this stuff for a really long time, but have been procrastinating on actually putting the work in to learn this stuff - but then you gone did and made these videos and these are so enjoyable and interesting to watch and I've "accidentally" learned so much that the whole thing kinda "clicked" a couple of nights ago. The same way programming clicked back when I was kid and trying to understand how programming works - I remember the moment things just kinda "clicked" and I realized I just got bootstrapped into how I can learn more. So I went and ordered an Arduino, a breadboard, some jumper cables and and assortment of components, and I can't wait to get my hands on them to gradually get to understand even more of these things. And maybe one day make that 6502 breadboard computer myself.

11:00 I'm not an expert, but I think phase shift is actually caused by the speed of light. Signal travels about 95% of the speed of light in a copper cable. If I read the scope right, the shift is around 10 nanoseconds. Over that time period, light travels around 3 meters. I wouldn't be surprised if the sum of the length of cable used for the scope and the extra wire on the breadboard would add up to around 3 meters.

Wouldn't you see a more linear response to increasing frequency if that was the main factor? I'm sure it plays a part, but the response seems to be quite sharply non-linear, which to me implies that it's more to do with impedance and capacitance, as Ben says.
