Unfortunately a great many of them use Sodastream’s gas cylinders - after their patent expired and anyone could build a compatible unit - so you might not be able to escape them getting your money when buying CO2 refills, if there isn’t another brand of gas cylinder available where you shop.

Sodastream have released a new cylinder design (with a bayonet rather than screw fitting), presumably to again attempt to kill off the market for home refilling from a larger CO2 cylinder, or use in other brands of machines.

All of that said, I do like my Aarke machine.

Damn, that was a chonky update. 17GB download, 85GB of files touched.

The website also shows a large unpopulated section of PCB near the network jack with “PoE” silkscreened:

PoE built in could make this a very interesting device indeed.

I got into an argument with someone once about this, when they told me (paraphrasing) “it’s safe to drive listening to music through headphones, because they let outside sound in”.

Yes they indeed might, but - even ignoring delay introduced from digital electronics - you’ve now lost all sense of where that sound is coming from, because you’re listening to the sound of one microphone being played through one speaker.

The human ear really is an incredible thing.
