It always seemed like an amazing way to speed-run repetitive strain injury to me.

Anything that requires that level of precision but offers basically zero range of motion just seems to force unnatural levels of tension in every muscle in your hand and wrist.

The things cause me agonising wrist pain within minutes of use, not something I’ve experienced with any modern (ie, larger than the postage stamp sizes of old) touchpad.

Good riddance.

Here’s another good example: https://www.youtube.com/watch?v=4cp28hIMP94

Stacking 283(!) double mains adapters and measuring the voltage drop. Because it’s not just the cable, each plug/socket adds additional resistance.

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.

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.
