We are funded! Next up: Stretch Goals

The Mooshimeter crowdfunding campaign has hit its goal with more than a month remaining!  It has been a real trip so far, and I’ve already blown through one keyboard’s F5 key tracking progress.  Now we get to further refine the Mooshimeter to better suit your needs, based on your comments, suggestions, and stories.  To that end, I’m happy to announce our first two stretch goals:

$60k: The Mooshimeter can interface with any almost sensor that produces a current or voltage and has banana jacks or a BNC connector (with a standard adaptor). Right now our app reports shunts, clamps, thermistors and thermocouples in native units, and everything else in measured units. We’ll make it even easier to read new types of sensors without having to do the mental math yourself. Tell the app about your sensor, and it will report in native units – Celsius, PSI, m/s, etc – no programming required! This will support arbitrary transfer functions and automatic range selection.

$70k: We are improving the overall accuracy of the meter, with special attention to resistance measurement.  We are hitting the volumes necessary to make the higher precision components affordable, and this upgrade package will tighten up the drift & temp co specs.

Below are a few of the stretch goals still in play. What is your favorite?  Let us know at

– Many of you have asked for support for current clamps. The good news is that we have done so since day one. We will expand this capability by adding software support to automatically calibrate an external current shunt with a current clamp.  This is great for measuring currents above your clamp’s ratings, or for cheap calibrated deployment of many meters.

– Do you want to take your Mooshimeter with you everywhere you go?  We can ship carabiner lanyards so you can easily clip and go.  Great for mobile applications!  Would you rather have a bag to carry the meter and leads? Integrate a velcro tie-down? Magnetic clip? Please let us know.

– Many electricians have asked about reading three-phase systems with the Mooshimeter. We currently have hardware and firmware support to make these measurements with three meters working in tandem.  We can add software support to coordinate these types of advanced measurements on your smartphone.

– For the math nerds we can offer customizable DSP filtering.  This will allow you to more easily extract signals buried in noise with FIR or IIR customizable filtering.  We’re still squeezing out the last few MIPS out of this processor, so this may end up on the app side.

Thanks all!

– Eric

EDIT: Feedback received!  Velcro tie-down is not what you want.

    Hello! Love this project. Just wondering if you are planning on releasing it as open source or not.

    I’m with Scott. Will this become open source? I think it’d be great to get some Devs together and bust out an app for PC.

    Thanks Scott and Chace. We’re definitely planning on releasing an API to allow other developers to talk to the meter. We’ve started on this, check out Technical Machine’s blog post on talking to a Mooshimeter:

    I have a Solar array that’s grid tied.
    Split phase for 220Volt
    What clamp on ammeters will I need to monitor buy and sell wattage
    with the Mooshimeter ? ? ?

    I would like to beta test your unit. Think your APP will run on iPhone 5S ? How about my iPad2 ?

      Hi John,

      In the demo video where I use a current clamp I am using a Mastech MS3300. Almost any current transducer should work though.

      Unfortunately we don’t have any beta units available right now. But the iOS app will run on an iPhone 5S and an iPad 2.
