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  (https://github.com/universam1/iSpindel/tree/master/drawer) and use Thingiverse (http://www.thingiverse.com/) to print it for you

I'm definitely interested though, as I was thinking of buying one of these  (http://tilthydrometer.com/products/brewometer)

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

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?

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

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

Bauteile

    Wemos D1 mini
    GY-521 Gyro & Beschleunigungssensor (MPU-6050 auf passendem breakout Board)
    DS18B20 Temperatursensor
    Lochrasterplatine 3x4cm
    Widerstände
        4k7 Ohm
        220k Ohm
        470 Ohm
    Mikro Schalter
    18650 LiIo Zelle (z.B. Panasonic NCR18650B geschützt oder ohne PCB)
    Lipo Lademodul TP4056 (6 pin recommended)

    Kunstoff Schlitten download
        alternativ (Lochraster) Platine UNGETESTED)

    Kunstoff Zylinder Petling Petling-XL

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  ;D

I think they might be too small?

I don't mind being a guinea pig to try out the completed unit, :).

Id gladly pay someone to put together some as well

There's a thread on buying these from the US in the members area.  Is there any more news on the open source version?

I'd be interested in giving it a go.

I've got a stainless steel fermenter and I'm wondering how this will affect the wireless signal to the device.

According to http://smallbusiness.chron.com/effects-metal-wireless-routers-73559.html metal can seriously disrupt wireless signals. No point in spending the cash if it can't connect to my router.

Anyone have any experience with stainless and WiFi?

Easy enough to test. Set your phone on wifi playing a saucy Rihanna video on YouTube, then put into the empty fermenter where you normally keep it. Close the lid. Listen carefully to the lyrics....
Don't let her indoors catch you doing this! ;)

good idea I am going to try that

Put wort and yeast in too to fully give it a test :D

It's always good to be thorough

I have one on the way.  :)

PET Preforms on eBay...

Watching this with interest.

Should have said

I'm going to go ahead and order one of these.

Orders over €100 get free postage. If there are 3 others that are interested we will get it posted for free.

I can get them delivered to me and pass them out at the Nationals.

I'm going to get this one ... https://3d-mechatronics.de/de/ispindel-diy-set-ohne-batterie_147.html (€26.51 each)

If I get a chance I'll even assemble it prior to delivery.

Mick02, would we not be better off getting the spindle kits and just buy the preforms separately?

Based on the pricing the container is about a tenner, these are about E3 each http://www.ebay.co.uk/itm/XL-BIG-PET-Micro-Geocaching-container-geocache-cap-Petling-preform-soda-bottle-/131430402355?hash=item1e99dcc933:g:xscAAOSwPYZU36py

Yeah, that website is a little confusing. The link that I posted says in the description - "This set consists of all components of the DIY WLAN spindle except the battery and the petling"

Then the other option, the €14.10 options states that "This set consists of all components of the DIY WLAN spindle except the battery, the petling and the sled"

The €14.10 option is unavailable now so either it's sold out or they aren't making any more of them.

I agree though buying the petling container separately is a better idea but I think that will need to be purchased regardless.

Probably a stupid question but how does it read the sg of the wort ???

Angle of the dangle

Yep, quite clever.

What's the accuracy like?

Not much interest in a group buy on these some I'm gonna go ahead and get one for myself.

I'll report back on the effectiveness and accuracy of the unit.

Mick

Mick I would be interested but want to see if they get back to my email re the E14 kit.  Would you be interested in waiting until they reply and we see what their situation is with stock?

Sure! I didn't realise that you had contacted them, apologies. I'll hold off until you hear back.

Anybody heard back from them?  :)

Not as yet.  Any of youse speak German?

Are we just concerned about stock?

I know few lads in CraftBeerPi community are using them wirelles hydrometers, will try to ask them. Manuel, developer of CraftBeerPi is beta testing interface for his controller to work with same wirelles hydrometer, hence allowing his fermentation controller read temperature and gravity live.

Lads would be interested in buying one of these also, even more so if somebody could assist in  assembly.

Does that mean either you are Mick will organise a group buy? If so can we start a list? Also not to be a pain but Mick would you please post a description of the exact product, price & a link to the description?

Many thanks.

Here is the link , there are a few different kits, the complete unit is 39 yoyo.

Will do & thank you.

At that price I'm interested in one of the complete kits as well. I can probably hack the brewpi to integrate the data.

It's looking like a quarter of the price of a tilt. Craftbeerpi have interfaced to it I am sure if Elco got enough interest he would add it to brewpi

I'll arrange a group buy for sure. I've never done it before so if someone could tell me how the payment is arranged I'll kick it off. If we can get this done before the nationals I will try to hand them out there (if that suits everyone)

I've moved this to the members section (http://www.nationalhomebrewclub.ie/forum/member-only-group-buys/open-source-digital-hydrometer-group-buy/)

I've received my kit.
It came with the pallet.
Just needs battery and PET preform.
I've not had time to figure preform yet, but these should be inexpensive.
Has anyone researched the PET yet, would love to just click and pay, lazy me...

Will it fit into a White Labs Vial??

Rumor was that they were PET bottle preforms!

Is there rally that much soldering involved as stated by vendor? I am a bit surprised that might take 4 hours of soldering for such a fairly small thing ( I am no expert in soldering, but have it done few times)

This is being discussed in the members area. We have a price etc from the vendor. Stick your preference in there
