Powering cellular IoT for months in the wild

For a LTE M1 connected IoT project that is meant to operate in the wild for months at a time, we’re designing a set of rechargeable power packs that will provide the electrons we need in an easily swapped out form factor. In the meantime, we needed some way to test the modules and profile…

Turning complex waveforms into usable values–VRMS, Power, Torque… how to do it and why it works

After this tutorial, you’ll know “in your bones” how to deal with the weirder stuff, when it comes to time-dependent values. It’s easy to find formulas to plug into to for simple cases, like a steady DC voltage or nice sine waves with known peak values but what happens when things aren’t so straightforward?  Say…
