    Battery Tracker - Voltmeter alternative

    These seem pretty cool (other than adding a permanent battery drain.. but then I guess the warning tells you when to charge it in any case)

    The Antigravity Battery Tracker is a Bluetooth Monitoring system for your Lead/Acid Battery’s health. Track its voltage, starting performance and charging.

    Anyone tried one? I guess if I was going on another long trip $35 might not be so bad for peace of mind......

    Looks interesting, but I did not see anything saying its waterproof or the physical size if its small could properly fit in a dry spot.
    just found then in uk it states the size is 2.75" x 2"

      What a coincidence...I've started a small electronics project to track the voltage of my charging system, and engine rpm.

      I'd be tempted to buy one of these instead, if they could be had for a reasonable price here and were a little bit smaller.
      Surprisingly, I couldn't find any similar products on whim.

        Well it's coming along nicely. This weekend I finally got around to (re-)familiarize myself with the Arduino platform, and wrote a first rough draft of a program which derives rpm from ignition, and measures voltage. Next up will be implementing writing the data to an SD card.

        Sneak peek:


        The future could hold a lot more and might get rid of the SD, but let's not get ahead of myself just yet...

          Now this is up my alley. How and what are you using to measure the engine RPM?

          The tach in my 1979 GS850G squeals like a mofo when it's hooked up, which means the bearing in there is shot. Buying random used tachs off of eBay is a total crap-shoot. I'm considering replacing the mechanical bits with a tiny servo and some circuitry to measure the RPMs. I have dabbled in Arduino (C++) but I'm more comfortable with Python so I would probably use an ESP32 and have a smartphone UI as a bonus.

            I'm aiming for an inductive measurement from the high-tension wires. Though the goal here is to create a datalogger which lets me correlate rpm and voltage over the duration of a ride, not creating a tach; rpm's get averaged and only recorded in intervals, combined with voltage.

            I'm using the Arduino mainly for prototyping, I've already ordered an ESP32 for similar reasons as you; built-in wireless functionality. Should I fail at porting the code over; I'll simply switch over to an smaller footprint, arduino-compatible board, adding some BT&storage module.
