Pics or it didn't happen :) Do you find that after a few weeks the tubes start to fill with wort?

It's commonly mentioned that the WiFi sucked on the BrewBit. Does anyone know what WiFi chipset they used? Was it the ESP8266?

Hi guys, I've put together some videos of my new DIY HLT stirrer build for my HERMS rig. My first video covers the need for stirring in my HLT. There are a lot of people saying convection is enough to even out the temperatures, but after poking around with a thermometer I was amazed to discover...

Yep. Great idea and it sounds similar to the BeerBug. I think the drawback is that strain gauges need frequent calibration which is why your scales calibrate every time you turn them on. Dangling a weight in wort for days, weeks or months without calibration leaves plenty of time for errors to...

I read an article over here that makes it sound do-able, but I also wonder if it could be easier to just use a 3 lead driver and the traditional feedback circuit to drive it. I doubt they make sanitary versions of these piezos though.

Has anyone tried measuring SG with the resonance of a piezo driver? I imagine if a piezo speaker were immersed into a liquid its resonance should alter along with the S.G of the liquid. I don't know how reliable the results would be but it might be worth investigating.

@Malfet, I looked into mass air flow sensors some years ago but abandoned the idea because I thought that the first blow-off event would destroy them (fragile hot-wire, difficult if not impossible to clean etc.). Was your sensor tolerant to blow-off events or did you use other measures to...

Thanks Jason, I'll stay tuned to see your progress. I've got a similar setup running off about 110W input power and I was only getting a drop of about 10f below ambient for a non-fermenting liquid. Then I added some insulation around the fermenter and it nearly doubled. In my case I'm using a...

Hey Jason, how's this project progressing? I was wondering why does your room temp appear to be zig zagging up and down until you start crash cooling? Also, did you have any troubles with condensation forming on the fermentor when you're crash chilling?
