What is Reddit's opinion of Designing Embedded Hardware: Create New Computers and Devices?

From 3.5 billion Reddit comments

If you just want to understand , it's much better to just read a good book, maybe this one:

If you want to be able to build , you also need to learn some tools. Depending on what level you want to build , it's either the Arduino(hobby) , the mbed(professional, IOT, but relatively close to the arduino) , or bare metal(professional , non IOT) .

OPT= internet of things.

Art of Electronics is an interesting read, but it's almost more of a history lesson at this point. The digital electronics section is really showing its age. And the pages of op-amps are all obsolete and long outdone by modern day parts.

The fact is, no one builds electronics anymore in the way that Art of Electronics presents it. Most systems are now built on the ADC->DSP->DAC model rather than some complicated analog control circuit made from vintage opamps.

I think you'd do better with a modern embedded systems book, like this one.

Unfortunately, there is not one single good reference for analog circuits. Analog circuits are so application specific that they are almost always integrated with the physical sensors (antenna, microphone, accelerometer, etc.) at the package or die level. The exception is power amplifiers. These are often impractical to integrate with digital and small signal analog circuits due to their high power dissipation. You can learn quite a bit about analog circuits by messing around with audio circuits. If you're interested, I'd check out this book.
