PI ZERO W PROJECT KIT
he most expensive of a
batch of four Raspberry
Pi Zero W project kits
from Pimoroni, the Pirate Radio
comprises a case full of quality
components – everything you
need to build your own internet
radio. As with the other three
kits, the packaging is top-notch
and the hinged plastic case
can be reused to store other
components after the build.
The key electronic items
featured in the Pirate Radio kit are
a Pi Zero W, with built-in wireless
LAN and Bluetooth, and one of
Pimoroni’s new pHAT BEATs. Also
available separately, the latter is
a neat bit of kit that crams dual
I^2 S DAC/amplifiers onto a Pi Zero-
sized board, and can pump out
3 W per channel.
The body of the radio is fairly
easy to assemble – from acrylic
pieces, legs, retainers, nuts,
and bolts – using the illustrated
step-by-step online guide
(magpi.cc/2o1i7d7). As long as you
follow the guide carefully to get
the orientation right, everything
slots together neatly. The acrylic
pieces are all laser cut, including a
neat speaker grille, so there are no
nasty rough edges.
The supplied 5 W speaker simply
slots onto four bolts holding the
translucent front acrylic layer in
place. Fortunately, the speaker
comes with a length of dual wire
already connected, so there’s
no need to solder it. We’re not
sure why the wire is much longer
than required, though; while you
could always cut it to size, we just
wound it round the bolts at the rear
of the radio.
Unless you opt to buy a couple
of Pimoroni’s ingenious hammer
headers separately, you will need
to break out the soldering iron
to attach the supplied standard
male and female headers to the Pi
Zero W and pHAT BEAT. The latter
then slots onto more bolts at the
rear of the radio, with the Zero W
mounted on top. The speaker
wires are inserted into a couple of
the terminal blocks on the pHAT
BEAT, with the latter’s dip switch
set to mono to combine its stereo
channels. With that, your internet
radio is built!
