So, what's the current status of everything?

[matzesu]

Im happy whe ditnt take my Posting for a Politikal Discussion about Onkle Donald and his Great Big Atom Button.. ^^

I wonder who gets the Red Prototyphe, its not my Color, i would like to be the Guy who gets the Blue Prototyph, but maybe i can get my MP Unit in Black or Blue..

Green would also be nice, like my GBA Micro, the Switch Lite and my Green Transparent GBA Classic...

 

[T.T.]

I have - no surprises there. A DAC fed a constant input value should have no problems outputting a constant voltage. If it can't do that, something is wrong with it. I'm not sure what kind of DAC you've used...

If the DAC has a DC blocking cap placed on its output, then that could certainly be a problem. But given that apparently the DAC drivers specify a DC offset, then blocking caps are probably not present (or not recommended by the datasheet). Although, I think the sound card in my desktop is AC coupled, I'll have to look at the board next time I think about it.

@Akko Maybe I misread something, but to me it looks like Confuzzled said "If you look very close, DACs can't reproduce square waves." and then you said "If you don't look too close, DACs can reproduce square waves." but word it, as if you were contradicting C. *scratches his head*

I guess these are the US-cellular prototypes we've been waiting for, 8 of them. I'm not sure I've seen that funky red lid before, and it seems to be being used with grey bottom plastics, so I guess it's actually an example piece ED it pressing into service.

Are those matte/coated black or are they normal black without coating?

... who is getting the transparent one? They look awesome!

Until you turn on lighting LEDs and it looks really blinding or simply a torch

I think transparent case would be nice as accessory, a replacement case on shop, but no as standard case.

Even I continue thinking it would be nice as an option to paint your case the way you want (painting internal plastic transparent case).

Green would also be nice, like my GBA Micro, the Switch Lite and my Green Transparent GBA Classic...

Green is the best color for the GB Micro imo, my brother used to collect them and he has had one in almost every color they came in, including most of the special editions.

On topic, I absolutely love the way the red one looks with the marbling in the case. I know the color discussion is closed for now, but these look really organic and I like it

Yeah we (those who like clear) don't care. Clear is awesome. And yeah I get it it shouldn't be the standard case thats totally fair.

IMO dishwater boring black case should be standard, clear should be limited edition only for the 1337 hackers, the other colours I have very little opinion on.

I hope you washed your hands after typing that.

Do you recognise your new baby from the photo @Grench?

Actually, I am not sure which one is mine. One of my early ideas had been marbled/blended. I love the one with the multi-colored marbled red lid. Most recently I'd said grey with black buttons is fine (based on the colors of the cases I'd seen to that point) because I really didn't want the colors to be what held this up.

So, most likely it will be one of the grey ones, but kudos to whoever gets that multi-colored blended red lid one - that turned out awesome! If I had a pick of the lot, that one would be it. But - I am perfectly fine with one of the grey ones as well. I'm glad to see that there is such cool variety in these - great examples!

Great to see progress on these - hope the testing goes well!

Weeeell, I still have a multicolor-blended red lid, so I can fix that for you

Awesome! Thank you!

 

[funkyarif]

Awesome! Thank you!

It looks too cool reminds me for a cross between Optimus Prime and the fisher Tell speak and Spell thingy which was in ET.
Omg I feel old now

 

[matzesu]

I looked at my Switch Lite, and it’s blue

 

[oskda]

clear [case] should be limited edition only for the 1337 hackers,

If you find 1337 backers for clear case, I am sure ED will do them. But I think it is not so popular.

 

[erico]

most likely without coat as one can spot the marks. beautiful none the less.

 

[rSl]

cool new protos! i love the marble red one. looks like leather somehow.
personally i like the grey ones best, as they remind me of my first breadbin c64 mixed with an sgi granite sparkle look.

(i had access to an sgi indy in the 90's and loved the granite look so much.)

its hard to compare even CPUs with the same ISA as simple change such as bigger pipe or bigger/faster cache or L1/L2 can make huge difference, even frequency break point is a thing, some CPUs even throttle more easily due to lower resistance and high voltage, which may give us the illusion that two very similar looking and spec CPUs would preform similarly, but actually they won't

The most accurate choice would be a proper benchmark such as cinebench, pi test or blend test...
I actually think cinebench scales really good, especially better than PassMark which is really a biased benchmark that favors apple fanboyism (though apple does modify ARM chips really good)

As for sound waves - whats the target sound device sample rate and bit depth? Maybe I can write NEON functions quickly and use SIMD to accelerate software decoding, it will save both battery with cpu load and time, the best solution imo is hardware

imo 20% usage bursts on sound play is equal to device planning failure, if the device is idle but playing sound, it will constantly switch its CPU governor between performance and idle profiles, this should result in quicker death of CPUs unless the governor is propely set up for the delays of the decoding agent, which is a bad choice for general purpose device

maybe its not possible to add hardware decoding now, but should be good to add it as hardware extension since the pyra is modular (love evildragon for that)

 

[levi]

The sound playback hardware expects 92kHz sample rate, 24 bits of depth.

 

[docbroke]

96kHz I think.

Admittedly I phrased my reply poorly so it can be read like that. What I was actually trying to contradict was his statement that DACs produce their output by adding up sinewaves of different amplitudes and frequencies which is just plain wrong (at least I have never come across or heard of a DAC that works that way). I'd also like to add that - while admittedly outputting square waves perfectly is not really possible - most DACs have less problems outputting a square wave than a sine wave.

I didn't intend to start a lengthy discussion on the topic though ^^"

If the DAC has a DC blocking cap placed on its output, then that could certainly be a problem.

Yes but I'd argue that a DC blocking cap is not part of the DAC itself and as such does not factor into this.

This looks like the little blue disinfectant blocks you see in urinals!

Looks like a tomb !
