The circuit board instead of the sled is a great idea. Shame it doesn't yet fit in a smaller PETling. For the pic above it looks like the D1 mini dev board is the problem, you could use the ESP8266-12E module (https://www.ebay.co.uk/itm/ESP8266-ESP- ... 1658225758) and add the support circuitry (circuit diagram here http://escapequotes.net/wp-content/uplo ... matics.jpg) to your circuit board. I reckon that could halve the width, but you'd have probably have to design and build with SMD components, which is obviously a bit more tricky.

For me, knowing the gravity while fermenting has little use, unless you want do the fast lager thing or have done a fast-ferment and know the FG and need to turn around your FV in super quick time, or have some pretty graphs. The last one is enough for me to end up building one...

I have both a Tilt and iSpindle, although have yet to use the latter in anger. It is surprising what it shows you about how your fermentation is proceeding, once you have used one I don't think you will want to go back to without it (I was surprised myself as I admit it was an impulse purchase via a friend in the US).

OK, I've convinced myself that no-one is going to be selling this 2nd hand as it's far too useful, so I've ordered an iSpindel. Soldering iron at the ready :D

At the moment I can see the usefulness especially in a Wheat beer, fermenting with WLP300, starting at 17C and ramping up the temp as the days go by and the gravity drops, mmmm lovely.

Oooo I am watching for the results and how the assembley goes.

I couldn't really say, I'm just the lucky recipient of someone elses' hard work. :D The other thing to consider regarding miniaturisation is the battery. The Tilt uses button cells IIRC, and you need to replace these every three ferments (or so I have been informed) The iSpindle uses a rechargeable 'AA' type battery and is capable of running for a month or more (with a 15 minute update cycle) on one charge. In the case of the non sled design the batter and holder is what actually holds it tightly in place in the Petling. The only reason for using a smaller unit would be the ability to drop it in a 1 gallon demijohn, as it is, it still fits in a better bottle.

I'm going to build it per the instructions on the iSpindel site, and then I might give shrinking it a go. It'll give me something to do in the long dark nights of winter...

"long winter nights" exactly my thinking.
... It's this or copper pipe shelves at the moment.

The ISpindel build is pretty straight forward.
Just watch out for the DS18B20 sensor pins.
They are quite close, careful or you might need to desolder!
Consider doing these at the start for ease of access.

I think my wife is happy that I am concentrating on relatively cheap brewing projects and brewing beer (that she enjoys as much as I do) rather than getting distracted by any number of other expensive hobbies that usually catch my attention during the long winter months

Have just finished building the Ispindel.
What is the favoured platform to use it with?

ubidots ... although the Brewpiless project does have a way to integrate the output ... still requires ubidots to set up though ... as per the instructions where you bought the iSpindle from

Cheers Ubidots was where my thinking was taking me I did look at monitor beer as well

Got the ispindel up and running here is the latest veiw from the latest brew.
Still a few adjustments on the maths to make but is loooking good.

Good stuff!

I've just ordered a bunch of components - I'm rolling my own - I reckon I can save a tenner, and I'll see if I can fit it in the smaller PETling. I'm also building a BrewPiLess to integrate with the iSpindel. Any gotchas to look out for?
