All drones are susceptible to many of the same fault and failure conditions, ranging from merely annoying to catastrophic, making robust electrical protection essential. The generic drone design in Figure 1 highlights some of the areas where circuit protection is critical.

Analog filters using inductors, capacitors, and resistors are critical to most circuits and systems. Whether as passive or active designs, it sometimes seems that they have been studied "to infinity and beyond" via theoretical constructs with very intense math, with practical "application note" designs and BOMs, and even with hands-on circuits with ...

How were you taught to determine the slew rate needed from an opamp? Ok, trick question; you were probably not taught that at all. But you'll have heard that an amplifier is "suitable for circuits where the output has to slew at up to 10 V/us" because the data sheet says the slew rate is 10 V/us. Let's see why this ain't so.

The autonomous solar powered boat is a great solution which utilizes electronics technology to realize a zero-impact for connected navigation on the water such as the case of the interesting SeaCharger experiment (see Figure 1):

I'll confess: I really enjoy making a well-crafted solder join between two wires or soldering a component onto a PC board. There's something very satisfying about the smell of the rosin (we won't talk about the lead fumes, of course) and the crisp eutectic transition of the solder between its solid and liquid states at 183 oC (for tin 63% /lead 37% ...

Spreadsheets are brilliant for filter design, and I write much less design software these days. Don't get me wrong, I love the BASIC interpreter that I use, BBC BASIC, available in a native Windows version and a multiplatform version (Windows, x86 Linux, MacOS, Android, Raspberry Pi and even iOS) using SDL2.0. It's a compact but complete Windows ...
