Just came across this digital hydrometer kickstarter. Says it will measure percent alcohol too.

I sure hope I get my Beer Bugs (wifi & bluetooth versions) soon - another Kickstarter project… It’s a little less expensive…

That thing looks like it will be a brewers best friend, I would love one, but out of the average homebrewers price range.

This is cool, but I wonder how it measures percent alcohol?  Seems like it’s not possible without knowing an OG.

That’s what I wondered, but there are no details. There are devices that will measure alcohol content directly, but most are very expensive. If that’s what this did, it would be quite cheap.
