Yes, this is linked in the introduction. Great reads.

Yeah, the article doesn't make it at all clear what the point of this project might be. I gathered by the end that the idea is to rip out the guts of an Ikea speaker, add some binding posts and a custom case, and come away with a hacked-up, 1-channel replacement for the Sonos Amp. Tell you what scares me though: I don't like seeing that they doubled the amount of DRAM in the new one. Hopefully they did that only because it was becoming impossible to source the 256MB module. I hate to see it because if they allow themselves to use it, eventually there will be a software release that doesn't work on the older 256MB model, and they'll deprecate it.

  Both IKEA and Sonos have been decent in terms of support of older hardware, so I wouldn't be too wary of that. But, companies rarely feel incentivised to maintain older products these days.

    I am pretty happy with Sonos support but they did already EOL all their original products up to everything with less than 128MB of RAM, on the basis of not being able to run the newer software. Those older platforms also had SuperH CPUs, which might have been part of the problem.

      That's why I said "decent", not "great" :) My Playbar from god knows when (5? 6? years ago) still gets updates and is on S2 now. But then yeah, there are the older devices which are EOLed. IKEA still supports 5-year old smart switches they no longer produce even with their latest smart bulbs. But no idea if that will continue with their move to Matter (or whatever the new hotness is called).

  The extra RAM is probably for the enhanced domestic surveillance module.

  It is almost certainly because its easier to source larger chips. The hardware product I work on has twice the RAM it needs, and an order of magnitude more eMMC than it needs, because we couldn't get smaller parts.
