There's nothing wrong with teaching like that. If the class is supposed to teach you something that isn't just "use the stdlib", then it makes sense to ban it.
I'm guessing the author is aware and just venting. It doesn't make it less frustrating though. It's almost like someone asking you to dig a hole with chopsticks.
There are 50 or so kits spread out all over the world, some in the hands of the world's best Thereminists, which has been quite gratifying. But the project has been in a bit of a hiatus while I do more R&D, and the current tariff situation isn't exactly filling me with enthusiasm. Enclosures and antennas have been a burden for some, a wine box build is probably your best bet. I don't mind supplying hand-wound coils and any guidance you may need.

I don't think it's reasonable to ding them for the second part. She has to actually fund herself somehow, and doing it by promoting products that actually meet the standard is by far the least offensive way of doing it.
Watching this comment tick down with more and more downvotes from people who get paid cushy software engineer salaries is absolutely comical.
You could make either side of the argument, tbh. If you wanted a completely independent and unbiased testing, you wouldn't want the group to sell/promote the products they test. It definitely presents potential conflicts of interest.
But, I went on Consumer Reports recently looking for a good smoke detector and saw they are now using affiliate links for the products they test as well, and I consider them well established and above board. So, everyone will have to make their own ethical judgment on how to take the results.
Summary, the samurai passed all their standard rollover tests and got great remarks from the test drivers about its handling and maneuverability. So they changed the test specifically to make it fail, and kept trying until it failed. Then they presented that failure as happening under normal conditions, singled out the samurai by name, and said it easily rolled in cornering despite their own testing showing it was actually quite difficult to make it roll.
As a result, Suzuki and Isuzu both left the usdm. Today, the Suzuki Jimny is one of the most popular SUVs in the world and America can't have it because consumer reports lied deliberately to American consumers.
Sure, you would definitely want that in an ideal world, but that isn't the world we live in. An ideal world would have the government funding this research, but that's laughable now. So with the reality we have to live in, this research has to get funds somehow.
It's not that it's wrong, but when someone stands to make money the assumptions we make about their motives change. If their whole business relies on advocating a fringe position I will not start with an assumption of good faith, or that they are just misinformed.
I don't know the economics of it, but they could run ads on their site, become a non profit & only accept donations, etc etc.
This is slightly unrelated, but I remember in the 2000s, there was a vendor of protein powders who started testing his and other vendors protein powders to see if their labels were true & they weren't protein spiking (adding cheaper collagen instead of whey lying on the labels, essentially). He almost immediately got sued from several large mfgs and had to shut down.
So, for this group, and the fact that they're ignoring cease & desist letters from the toothpaste mfgs they're testing puts them in HUGE legal risk, I suspect, and would not be the least bit surprised if all the funds they're collecting are going to end up in lawyers pockets.
core.logic has a lot of limitations you pretty quickly run into, and they languish on their bug tracker for years now because nobody actually works on it.
It needs to do a lot more than that if you want to have something that doesn't alias like crazy. And significantly more if you want it to sound like a game boy.
Well, the output of the wave shaper approach in the article is exactly the same sharp digital square wave that you'd get from a trivial square wave generator.
But I overlooked the point that the GP mentions that the processor source code must be loaded from a separate JS file. That's some quite annoying overhead.
What I was trying to imply was that it's not enough to build a square wave generator to sound like a game boy. Even if that generator in the game boy was a perfect square wave generator, which I'm not sure it is.
The sound created by that generator passes through a fairly complicated filter known as The game boy's speaker. To properly create a game boy sound, you need to find or take an impulse response of that speaker and convolve it with the output of your oscillator.
Well, and a single recorded impulse response is probably not enough, either, if you want to be super accurate. The directivity pattern is probably awful and shaping the sound as well.
I know all of that. But I just didn't want to get into these details in this thread.
I'm not an expert on GB chiptune, but from what I've heard from enthusiasts is that different GB models sound different, and even within the same model there are variations. That said, it wouldn't surprise me if the GB waveforms aliasing, at least from the digital side, given that it was operating with pretty minimal synthesis capabilities. There's probably some extra low- and high-pass filtering that shape the sound after the waveform itself is generated. Looking at some examples of actual GB PWM waveforms, for sure some high-pass would make a pure PWM waveform more GB-like. And some low-pass could help a bit with aliasing.
it does, you definitely "feel" the change. I actually have to do some digging to figure that out, I unfortunately do not have my childhood GBA anymore so I have to rely on audio clips to make that call
Don't forget to factor in the Gameboy speaker in your listening of those audio clips. That's a major factor that will change how these waveforms sound very significantly. Those clips, and the classic sounds of chiptunes, are never "just" the sound coming off the DAC.
