On one hand, cool! I've been wanting a local smart speaker for Home Assistant for a long time now, and in fact had been planning to DIY some myself (eventually...). With this, I could just buy a thing and be done with it!
On the other hand, holy shit, $50 for barely-above-microcontroller-level hardware. ☹️ I have a stack of old Google AIY Voice kits (bought when they were being discontinued for $5 each) and Raspberry Pi Zero Ws (bought before the prices went crazy for $5 each) sitting around to use for my DIY plan, so that'd be a BOM (including stuff like SD card and 3D printer filament) of more like $20-$25 for a much more capable device. Thus my expectations are anchored, to Pine64's detriment.
Perhaps unfairly, I feel like this Pine speaker ought to be more like $20, $30 tops. Especially since it doesn't even come with a proper wall plug, just a USB cable that you've got to supply your own wall-wart for!
