Luxonis Oak-D
AI Camera
$299 luxonis.com
The Oak-D consists of three cameras: two
dedicated to stereo vision that help identify
the exact location of objects in 3D space
(much like how our eyes work), and a third
that provides a 4K color image. Inside is
an Intel MyriadX chip, which synthesizes
these images and provides machine
learning inference processing. This allows
the Oak-D to recognize objects, facial
expressions, or whatever machine learning
model the user chooses.
It also means that while you will still
need a computer to run the camera, the
MyriadX can handle most of the heavy
lifting. Instead of a desktop with a high-
performance graphics card, you can run it
with a Raspberry Pi. I tried the Oak-D on
a Mac laptop and Pi 3, with both systems
performing at about the same frames
per second.
The flexibility of using multiple systems
for development makes for an easier
workflow; you can create and tweak
code on a laptop or desktop and move
to a single board computer like the Pi
when you are ready to deploy. Luxonis
provides walkthroughs for getting started
on Mac, Pi, other Linux systems, as well
as Windows machines. This device is a
powerful and flexible way of seeing the
world around you. —Kelly Egan
Marvelous Magnetic
Machines: Building
Model Electric Motors
From Scrap
$30 artisanideas.com
I have a soft spot for things built from
junk, and when those things happen to be
precision electric motors I can't but help
get extra inspired.
In this book, author H.P. Freidrichs
breaks down the basics of how to build
motors from things you can often find
at garage sales and other second hand
markets. To really nail home how cool this
is, simply look at the cover. Yup, that’s a
magnetic motor built around a kitchen pot.
Even if you never actually build the
items in this book, you’ll learn a lot and
be thoroughly amused by the author’s
enthusiastic use of odds and ends.
