    Brew in a basket > Brew in a malt pipe?

    I have a Klarstien Mundschenk XXL, 50L capacity. It struggles with small beers or small batch size, because it's got a generous dead space at the bottom. In addition to this, with "the right" amount of water in, it often runs a fine line between no re circulation and running dry. I've also...

    iSpindel - digital WiFi hydrometer

    I dug out a spare Wemos d1 Mini and wrote a simple little bit of code that just periodically connects to the wifi then goes into deep sleep. I measured the current consumption and it was as it should be: basically nothing in deep sleep mode. So I loaded that same code onto the iSpindel and it...

    iSpindel - digital WiFi hydrometer

    Yep, it's a Model 8 MKII my grandad left me. I've actually ended up using it quite often because it's rather robust and has a very large operational range. I've borrowed my mates Fluke 115 which shows 0.000A when the iSpindel switch is in the off position, but 0.064mA is below the meters...

    iSpindel - digital WiFi hydrometer

    Yes, it was an average derived as you guessed. I'm also on the latest firmware (6.3.1) from the github. Nothing custom. Turns out all my digital multimeters have blown fuses on the mA scale. Ordered more and tried my "ornamental" Avometer. Calibration seems questionable but at least good for...

    iSpindel - digital WiFi hydrometer

    From the colours on them I have a 220K, 4.8K, and a BAT diode. Supposedly a BAT43 from what the kit said, but not sure how to check now it's soldered under the Wemos D1 mini.

    iSpindel - digital WiFi hydrometer

    I took the LED off the Gyro, left the one on the Wemos D1 mini. Most of the time there are no lit LEDs on the board when it's in use. I've tried 900s interval and 3600s interval, and the voltage drop is the same. The LED on the Wemos is off most of the time, and flashes briefly at the update...

    iSpindel - digital WiFi hydrometer

    This thread is gold. I just built an iSpindel from an OSD kit off ebay (The Jeffrey V2.1). Calibration went fine. It's position in the tube is repeatable enough. Linked up to Ubidots. It only lasts about 8 days though? That was with a Samsung 25R 2500mAh 18650 (43g), which I verified the...
