Vinyl Sales Ran Circles Around CDs In 2022

How do you take your music these days? For those in Camp Tangible, it seems our ranks are certainly growing, and in the analog direction. For the first time since 1987, vinyl record sales have outperformed CD sales in the US, according to a new report. The CD, which saved us all from the cassette, was a digital revolution in music. But for some, the love was lost somewhere among the ones and zeroes.

Those who prefer pure analog troughs of sound cut into wax have never given up on vinyl, and the real ones probably gobbled up a bunch of it in the 90s when everybody was CD-crazy. But mind you these aren’t used vinyl sales we’re talking about, which means that enough new vinyl has to have been readily available for purchase for quite some time now. Although it doesn’t really seem like that long, new vinyl’s been back for almost 20 years — and according to the report, 2022 was the 16th consecutive year of growth for record sales.

So Why Vinyl?

Nostalgia ain’t what it used to be, but there was a time in my 1980s childhood when vinyl was all this scribe had to listen to. I have historically been a bit slow to adopt new music formats — I didn’t have a CD player until 1998, and it was given to me for my birthday. I was excited to get the thing, mind you, especially since it had 10 seconds of anti-skip protection (which of course was a huge concern with portable CD players).

But CDs are way different from records. Sure, they’re both round, but the similarities sort of end there. For one thing, the artwork is disappointingly small compared to vinyl. And the whole gatefold album cover thing isn’t really possible with a CD, unless you forego the jewel case and release it in a chintzy little cardboard jacket. But then people will have this one disc that’s four times thinner than the rest and it throws everything off in the collection.

New Part Day: TI Jumps In To The Cheap MCU Market

March 21, 2023 by 75 Comments

One of the interesting areas in the world of new parts recently has been at the lower end of the microcontroller market. Not because the devices there have new capabilities or are especially fast, but because they are cheap. There are now quite a few parts from China under 10 cents apiece, but have the Western manufacturers been able to follow suit? Not quite, but Texas Instruments has a new line of ARM Cortex M0+ parts that get under 40 cents in volume in their cheapest form.

That bottom-of-the-range chip is the MSPM0L1105, a single-core 32 MHz part with 32k of Flash and 4k of RAM. It’s got all the usual peripherals you’d expect on a small microcontroller, but the one which made our heads turn was the on-board 1.45-Msps ADC. On a cheap chip, that’s much faster than expected.

So there’s another microcontroller, and it’s not as cheap as some of its competition, so what? Aside from that ADC there are several reasons to be interested, it has TI’s developer support if you’re in that ecosystem, and inevitably it will find its way on to the dev boards and SBCs we use in our community. It remains to be seen how it will fare in terms of the chip shortage though.

Meanwhile, here’s a reminder of that cheaper competition.

Building The World’s Largest Nintendo 3DS

March 21, 2023 by 2 Comments

While the Nintendo 3DS was capable of fairly impressive graphics (at least for a portable system) back in its heyday, there’s little challenge in emulating the now discontinued handheld on a modern computer or even smartphone. One thing that’s still difficult to replicate though is the stereoscopic 3D display the system was named for. But this didn’t stop [BigRig Creates] from creating this giant 3DS with almost all of the features of an original console present.

The main hurdle here is that the stereoscopic effect that Nintendo used to allow the 3DS to display 3D graphics without special glasses doesn’t work well at long distances, and doesn’t work at all if there is more than one player. To get around those limitations, this build uses a 3D TV with active glasses. This TV is mounted to a bar stool with the help of some counterweights, and a second touch-sensitive screen courtesy of McDonalds makes up the other display.

The computer driving this massive handheld console runs Citra, and also handles the scaled-up controls as well. To recreate the system’s analog touch pad, a custom joystick tipped with conductive filament is used to interact with a smartphone hidden inside the case. Opposing rubber bands are used to pull the stick back into the center when it’s not being pushed.

Plenty of 3DS games are faithfully replicated with this arcade-sized replica, and as Citra supports various 3D displays, upscaling of the graphics, and the touchscreen interface, almost everything from the original console is produced here. There are a few games that don’t work exactly right, but all in all it’s a remarkable build and, as far as we can tell, the largest 3DS in the world. Don’t forget that even though this console is out of production now, there’s still a healthy homebrew scene to take part in.
