Strange Frequencies: The extraordinary story of the technological quest for the supernatural – Peter Bebergal

Amazon overview excerpt: A journey through the attempts artists, scientists, and tinkerers have made to imagine and communicate with the otherworldly using various technologies, from cameras to radiowaves.

Strange Frequencies takes listeners on an extraordinary narrative and historical journey to discover how people have used technology in an effort to search for our own immortality. Bebergal builds his own ghostly gadgets to reach the other side, too, and follows the path of famous inventors, engineers, seekers, and seers who attempted to answer life’s ultimate mysteries. He finds that not only are technological innovations potent metaphors keeping our spiritual explorations alive, but literal tools through which to experiment the boundaries of the physical world and our own psyches.”

As you could imagine this book was right up my alley. I actually built a few of the devices that were referenced before I read it. Precognition! Well, perhaps more mundanely just an interest in the same subject matter.

As you can see from my wordcloud that “golem” was frequently used term. Not surprising since Bebergal devoted more than a few pages describing the fascinating golem folklore and associated topic of automata. Who knew that the golem was really the first Terminator!

Berbergal also briefly touches on one of my favorites: the “Symbolic Hieronymus Machine“. I built this device, and if you want to follow me down this rabbit hole I suggest reading up on radionics.

See my wordcloud below for what this book is about. Leave a comment and let me know if like me, you enjoy this subject matter as well!

Which Pi am I?

Typically all of my projects are built with single board computers.

I typically use Arduinos, BeagleBones or Raspberry Pis depending on the specific use case.

If you’re like me and have been doing this for a while, you probably have several versions of the pi laying around, and it’s not always immediately obvious which version you’re holding.

This is important for things like understanding CPU and memory specs, pinouts and available peripheral ports.

Here’s a great site that has a table of all available models and makes it really easy to identify a board.

Because sharing is caring.

If you have access to a shell you can also find your Pi version by issuing a cat to /proc/cpuinfo:

Find the Revision number (second field from the bottom) and then compare to the table below.

Engineering Notes

When I build things I like to document the engineering end. These are tips and tricks or links to hardware or coding documentation somewhere. These posts are not presented in any particular order, I’ll probably use as a reference to save time in the future. I hope you find them useful.
