Oh I see! Yes, I was busy playing N64 at home, playing Pokémon on Gameboy, getting into Pokémon TCG, and drawing in class instead of studying and doing my math homework. Very productive!
ha, me and my mates spent our time playing Goldeneye and Mario Kart 64! Hell, even when we got to sixth form we used to book the theatre out under the premise of doing video production work and instead played Mario Kart and Smash Bros 64 on the full size theatre screen via the projector
You only need complex numbers (high-school maths) for the most part.
An Analog RC Lowpass Filter
Code:
-*--- R ---*--*
| |
u0 C u1
| |
-*---------*--*
setup: R = 1MOhm, C = (1/2*Pi)µF ~ 0.159µF, u0 = 1V input, u1 output
Do the following
(a) compute the impedance Z(w) of the RC lowpass filter over all frequencies
(b) plot the magnitude and phase of the impedance over the range [0,10Hz]
(c) compute the -3db cutoff frequency f0 in Hz from (a)
(d) compute (or read off) the magnitude and phase at f0
Hints:
(a)
use the (complex) voltage divider rule, i.e. Z := U1/U0 = R1/(R1+R0)
(b)
plot mag(w) := |Z(w)| and phase(w) := arg(Z(w))
(c)
for what w0 (w0 := 2*Pi*f0) does U1 = U0/sqrt(2) hold? (set U0 = 1)
(d)
plug w0 into mag(w) and phase(w)
If you can do all this, then do a high-pass filter. Same logic. Go from here.
Bruh... I live in America. Higher ed is for the rich or for those looking to be in debt up to their eyebals for a decade or two... And I'm already in debt. I literally don't even know what some of those symbols mean. lol
Regardless, I would like to take some community college in all seriousness, but first I have to get a new job... One thing at a time.
I did used to work as a CAD drafter for years, but same as Madao, I fucking hated that career. What maths I did have in my head have long since faded.
Based the two pictures I took and yours, my WiiU@480p pic looks similar to your 1080p pic, maybe a little better or worse. But your 1080 pic looks much better than my awful 1080p image.
Did you take your pics after starting the game? I didn't see bad distortion in that battery menu until after I booted into a game. I should retry it with Skyward Sword too if that's what you're using. Maybe not all games scale equally as bad?
I did start the game. I was in the title screen. One thing I'll say that I don't think people have mentioned about the Wii menu is that the Wii menu, and that includes the vWii menu, has alway looked especially awful in my perception. Like something about it makes it looks far worse than anything I've seen while actually in game. It's strange.

I was watching Kevtris disassemble a PVM yesterday on youtube. In the comments someone asked him how/where he learned all his stuff. He said he was self taught; no college. College, or lack of, shouldn't be an excuse.

Or... People learn differently. I'm a very "conceptual" person. I need concepts, which means someone needs to explain how things work and why they work the way they do. Which also means maths by themselves are not always a good way for me to understand. I mean, I've learned a lot of things by myself over the years but I can only go so far before some things become more esoteric.
Only reason I learned how an internal combustion engine works and even some of the math behind it is because things are far more easier to see at a macro scale IRL and in my head. In contrast, I've been at with electronics for even longer than cars and I don't have anywhere near the same grasp with them.

Yeah but he's been "self learning" about fpgas and computer/hardware engineering for damn near two decades. I've been teaching myself about hardware eng (from a software eng background but still) for a few years and already picked up a lot so yeah still impressive but not exactly unexpected. That much real experience beats book learnin' any day.
Hobby experience is experience. If someone came into an interview at my work and said they'd be working on complicated open source software projects for 10 years but never worked in a real software engineering job we'd hire them for sure.

Most engineers I've worked (and I've worked with a lot) almost always have hobbies outside of the scope of their field. An engineering mind is much more enabled to take on other tasks IMO.

What he is doing is nowhere close to what Industrial Engineers generally do. I am an Industrial Engineer. IE is more about processes (think theory of constraints) and has lately moved into more Systems Engineering (Verification/Validation). The core of IE work has historically been focused in manufacturing (which is not around in the US much anymore).

Very true. It's why I am here tinkering around with old consoles, lol. I also like working on my car a lot. I sometimes think I would rather be a mechanic...then I spend a couple days doing hard work and it changes my mind back.

The FPGA stuff? I would classify that more as Electrical Engineering and/or Computer Science and Engineering.
IE work, lets take Hi-def NES for example, would be what's the best way to take the detail parts and assemble/install them while minimizing waste (wasted time, effort, parts, movement, etc).
That said, I am speaking from the US education viewpoint. It may mean different things elsewhere. [edit] The Industrial part of IE is a common misunderstanding as well. It's origin is in relation to the Industrial Revolution.
edit2, I guess Electronic Engineering (subset of Electrical) would describe his work: (excuse my wiki link but I think it fits)

Electronics engineering, or electronic engineering, is an engineering discipline which utilizes non-linear and active electrical components (such as semiconductor devices, especially transistors, diodes and integrated circuits) to design electronic circuits, devices, Microprocessors/Microcontrollers and systems including VHDL Modelling for Programmable logic devices and FPGAs. The discipline typically also designs passive electrical components, usually based on printed circuit boards.
Back on topic, for PVM owners do most, all, none(?) of you use bnc terminations? The manual states it is an automatic termination unless something is connected to the out port (generally indicated by a resistor symbol by the port).
Ok thanks. I may have misheard the my life in gaming pvm episode. I thought I heard them say some PVMs require them, and then I saw video of them attaching a terminator to a port with the resistor symbol. It contradicted the manual so that's why I was asking. I'll have to go watch that part again.
Guys, what's your advice for someone who's invested in an XRGBmini & JP21 RGB ecosystem but would also like to give back some life to an old Samsung CRT that can handle component beautifully? The research I've done here points to grabbing a CSY-2100 or clone, and I suppose a JP21 to euroSCART cable. I'm willing to go through more hassle upfront to make this easier to use regularly. Wonder how tough it'd be to mod one of those boxes to self-power and take the JP21 pinout?
right now i get by with youtube videos in my channel.
long term i have no idea. the jobs in my country suck and there's nothing i like. i guess i'll just have to get some generic job eventually if i don't find anything i like doing that has good pay here (leaving the country is not an option).
As of early 2016 the Framemeister is rougly 330 EUR when bought directly from Japan (including taxes when bought from Solaris JP). The price of the OSSC isn't set in stone yet, but assembled units should remain under 200 EUR all things considered.

while they're both very good upscalers, you might do some research before committing to one or the other. They are basically at opposite ends of the upscaler spectrum as far as functionality.

What are these inputs on this JVC 13" that is still available? Does it have traditional RCA audio outputs so I can pipe it into my speakers or headphones?
I am interested. The issue isn't for lack of interest or lack of effort on my part. It's just lack of skill and ability in the present. I'm incapable of learning complex maths on my own. Mathematics don't come naturally to me. I can become very good at maths, but only after very long and arduous study, practice, help by tutor, and professional teaching. Even then, conceptualizing how it applies to real world solutions is an abstract for me. It's not a straight forward application. I need to see physical correlation for it stick in my mind and not fade away.
In other words, I require a ton of hand holding. And that's just not something I'll have access to for a long while.
If I have a Framemeister and I'd like to hook up a Playstation to it, what type of SCART cable should I use? There's a paragraph on retroRGB that talks about this but I'm not 100% sure I'm interpreting it right, so I thought I'd ask here just to make sure I don't order the wrong thing.
PlayStation 1:
Recommended solution: RGB Cable (above), sync-on-luma
PS1 consoles all output 240p, so using an RGB cable will get you the best picture. I suggest using luma as sync to reduce interference found in cables that use composite video as sync. Either way, if your switch requires csync, you'll either need to add a sync stripper to the SCART cable, or order a cable with a sync stripper built-in. If just your display requires csync, then ordering the cable as-is and adding a sync stripper right before the display is the easiest option.

I had an RGB sony trinitron CRT here I bought from gumtree for a fiver a while ago and i just sold on gumtree for £20. The guy who picked it up earlier only wanted it for time crisis
Thanks, Madao and Televator. I think it's safe to say this menu simply looks like crap and the letters are not uniform "on purpose," meaning it's not anything the console or display upscaling is screwing up.
