open source digital hydrometer

That's rather curious. Seems to be a decent digital hydrometer you can leave in your brew, and have it send out updates to how fermentation is progressing. They are usually €200 or more. Anyone up for trying to make some ? Just need a 3D printer..

Partridge 9 did a review of the beer bug here.

you don't need a 3D printer, yo ucan take the STL file from here and use Thingiverse to print it for you

I'm definitely interested though, as I was thinking of buying one of these

Can you explain how that little yoke would measure your gravity?

[Sorcerers Apprentice]

A hygrometer is used in air conditioning for measuring moisture content of air, wet bulb and dry bulb temperature etc

Did ye read the Github readme file?
To start it is a Hydrometer (OP corrected) - it works on the basis of the change of the angle of  tilt.
The change in tilt angle directly corresponds to a change in gravity.

Sorry John I thought I'd put a smiley on the end of that remark, no offence intended 😘

This looks very interesting

Well I tried :-(.  Where would you get the container for it as well as the all the computery bits?

[Ed]

this is the container (from the readme file...)

http://cachers-world.de/de/Petling-XL


All the computery bits (sensors etc) you can get on ebay or aliepxress etc.

Ta Ed, just on the container, we're not to use blue plastic I thought in fermentation?

This is what you need to make it so:

Yeah, i don't know about the container being food safe - the lid shouldn't be in the beer, but I imagine there'd be krausen getting onto it? I suppose any similarly shaped vessel could be used - glass with a rubber stopper might be safer from a flavour point of view?

quick search - maybe something like this?

I must have missed the smiley ☺ I'll blame tapatalk.
What about the old whitelabs vials?
They have to be food safe, would they do?

I've a 3d printer here if needed.  I work with polymers on a daily basis  and i can produce replications also. If someone can sort the electronic side out we could all get these cheap

This looks interesting. How about group build? 
I would pay somebody to put two or three of those for me together
