This design appears to be 220VAC only. And I’m assuming all metric threads and other measurements, too.

I think I could live with all the other components being metric, if they just had a way to work with standard U.S./Imperial containers as well.

Oh, and they need a 120VAC design for the motor and all the electronics inside.

Or, a design that can handle both 120VAC and 240VAC, as well as both 50hz and 60hz.

As far as I know mason jars (of that size) are the same everywhere so it should work with whatever containers decided to use that standard

After reading the BOM it looks like the only electrical components are the limit switch, rotary switch, motor, and the support components soldered to the motor, so a 120VAC design would only need to replace those with equivalent 120VAC components.

AFAIK that would either be a 120VAC model with a PCB to compensate in 240VAC areas or a DC motor with PCB

Possibly interestingly, some places in the world aren't either 120v nor 240v. Japan for example is 100v.

It's open source, you should make these updates!

I regret to inform you that I am not competent to make electrical systems design changes on a device like this.

This is the perfect thing to learn on. It's actually a very simple thing as these things go. I expect there would be just a few changes needed, typically the components used in these things are friendly to this need and you just need to reconfigure them a bit or order a slightly different part number for a few components.

God speed

You know, if this was software, I would agree with you.

Let’s just say that hardware and I are not a good fit.
