    iSpindle - DIY Electronic Hydrometer

    Yeah, I would be interested in seeing this as well. Anyone willing to share their Ubidots widget setup?

    iSpindle - DIY Electronic Hydrometer

    I had major issues with my setup for my iSpindel at the start. The issue was I didnt clean off the PCBs before soldering them, and had a few cold joints despite it looking perfect. At one point just pressing the iSpindel into the tube would cause it to reset, so retouching them is certainly a...

    iSpindle - DIY Electronic Hydrometer

    Ok, so it seems (what i didnt know) that the readings are in PLATO, that accounts from some trouble understanding the numbers. As far as the polynomial, i cannot seem to find a calculator that will spit out a number that actually works. I've tried like 3, saved them to the ispendel, and the...

    I dont understand either of these Gravity readings. Water: Tap water Polynomial: -0.00031*tilt^2+0.557*tilt-14.054 - this is the example given on the page Tilt: 24.96 degrees Temp: 70.59 F Batt: 3.97v Gravity: -0.402 Water: Tap water Polynomial: -0.050364959*tilt^2 + 6.868698667*tilt -...

    iSpindle - DIY Electronic Hydrometer

    Hi, have an ispendel built and have some questions about setup and Ubidots. I've done some of the basic calibrations tasks. I have balanced it to 25.7 degrees, and have placed it on a level surface and calibrated it. With sugar and water i have taken a few measurements as follows 25.73 @...

    iSpindle - DIY Electronic Hydrometer

    I tracked down my intermittent issue, I have a bad trace on the wemos. The RST pin and D0 are connected via the Bat 43 diode, it's part of the wake up system. Currently it runs, flashes, and sends data....but it won't come out of sleep. I need to know where the RST and D0 pins actually connect...

    Few pics of lead weights in painter tape. Ugly but...till I can get proper wheel weights it'll do. This weighs .35 oz / 10g.

    I'll share this. My iSpindel in tap water rested at 16 degrees. I taped a quarter to the outside lid and hit 18.5. If that quarter where lead, you'd be very close, but who wants lead in your beer. So the solution is to 3d print in petg, but my printer doesn't get hot enough for that. Otherwise...

    Sure, I'll take a photo tonight, and maybe weight it. It isn't pretty but I was able to get 25.5 degrees easy enough. I used a lead screw anchor (see pic) , smashed it flat, then bent it to fit like a half moon inside the very top of the tube just above the USB C port. I then cut it in half...

    Thanks @Open Source Distilling ill check it out. It's the 4.0 PCB. I'll check the link, but I notice your video offset calibrated with the lip at the top of the tube touching the flat surface, while I've also run folks calibrating with the tube flat to the table. What practice is better? I can...

    iSpindle - DIY Electronic Hydrometer

    OK, so I retouched all the solder joints. Seems to have fixed everything. I have it flashed and its saving everything. It calibrates at 89 degrees, and in water is 16.4 degrees. Ive read it needs to be 25 degrees in water, but I think i was before we had the option to fast calibrate on a level...

    iSpindle - DIY Electronic Hydrometer

    Setup an iSPindel last night, but had a lot of trouble flashing. Plugged it into windows and it assigned a device name (CH340) and port number (7), I open Nodemcu and it said "Waiting MAC" and nothing was happening. I cycled the power a several times quickly and itfinally populated the MAC...
