Kicad: Techniques, Tips and Work-arounds
Kicad: Techniques, Tips and Work-arounds

Kicad is an cross-platform, open source, electronics design suite.  I’d toyed with it in the past, but had never made it to actually designing real projects with it until recently.  Here, I’ll go over my experience and initial impressions, and provide a few pointers and resources for anyone curious about trying it out.  We’ll tour…

Transmitting mounds of data in realtime over Bluetooth Low Energy
Transmitting mounds of data in realtime over Bluetooth Low Energy

My client needed to receive a relatively large amount of data on a mobile device, from an embedded system, and process it in near-realtime.   The simplest method for communication with a whole host of mobile devices is to go over bluetooth low energy, but this protocol’s main concern is more about power conservation than throughput. …

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…
