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.

I had wanted to do this about 40 years ago. An older, more experienced friend told me, "No way: it won't work", citing complications like capacitance and inductance. You've proven that it can, in fact, be done Thank you.

@MrGoatflakes 4 года назад

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

@rickperez8044 2 года назад

@@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 года назад

@@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.

Ok man, it's time to talk seriously. You need to start making videos about the math involved in electronics, signals etc. This video is outstanding but what I loved the most is that you explain the clock signal and the fourier transform with ease.

@DarthZackTheFirstI 4 года назад

the sum of the frequencies (discrete complex values), as he showed, are fourier series. fourier transform would be a non periodic signal (but yeah, works also for periodic) with a continuous superposition (steady change in frequency) i.e. decaying signal.

You're quite right. I'm unemplyed telecom engineer and young techies laugh at me when I try to tell them how computers work. But as I know I have a 15 year old computer that I'm using just now. I bought third set of hard drives to it today because the secoind set I'm having in them give signals that they'd be dead in a year. How do I know. Because I've worked with servers in my life so much that I know what are the signs of failing hard drives. 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. I use thermal camera once in awhile to look what is going on and they are just keeping cool.

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.

You gave a very good explanation of the Fourier transform without actually mentioning it by name. You don't actually have to read the busy flag, in fact most arduino LCD libraries don't. What you do need to do is to add a wait loop between each instruction access of the LCD. 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.

@@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...)

Remember back in the 80's they had chip carriers that had the .1 uF caps across the Vcc and Gnd, so you did not have to do that on your circuit board.

Yeah doing it in Minecraft is best as you don't have to do the hardwork of actually cutting wires and stuff. Also it makes a lot of stuff kinda easier due to mechanical components (pistons etc.)

@Zougloulevrai 4 года назад

@@noether9447 It also makes some things harder, since signal needs to be repeated every 15 blocks, and since you're making a CPU and logic constructions, you need to space things a lot and get reaally long wires and place them by hand. But you also don't need to play with ground and power lines the same way. I'm not sure that's really just easier, I think it takes much more time.

I like to transfer my breadboard successes over to blank, matrix style thru-hole PCB and design the circuits on graph paper with a pencil and later pen. I build the traces on the bottom side by bending the components leads instead of clipping them. I hope to do the same with some or (hopefully) all of these subparts you have built. :)

@cfhay 4 года назад

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.

@keithklassen5320 3 года назад

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.

@janikarkkainen3904 4 года назад

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.
