Assembling Mood Light This tutorial will guide you through how to assemble your Mood Light kit. Use Mood Light as a night light

on your bedside table, or just sit it on your desk or bookcase.

It uses our Unicorn pHAT RGB LED board that has 32 programmable pixels that you can code in any one

of a zillion ways - have it fade through all the colours of the rainbow, use it to reflect your mood on

Twitter, have it fade through colours that match sunset and sunrise, or flash when someone mentions you

on Twitter.

The assembly will be split into two parts: soldering the headers to your Pi Zero W and Unicorn pHAT, and

assembling and screwing together the acrylic pieces.

It should take around 30 minutes to assemble everything.

Soldering the headers Both the Pi Zero W and the Unicorn pHAT boards will need a 2x20 pin header attached. Your Mood Light

kit comes with a male 2x20 pin header for the Zero W and a female 2x20 pin header for the Unicorn

pHAT.

We have a guide here that you can follow to learn how to solder headers to pHATs. Soldering the male

header to the Zero W is essentially just the same process, except the header should be soldered on top. The

photos below show how each header should look when soldered.

If you don't own a soldering iron, or you're just not a pro-solderer yet, then you could use one of our nifty

hammer headers that don't require any soldering at all. Our hammer header kit comes with a male header,

female header, and a jig to safely and securely attach them to your Pi Zero/Zero W and pHAT.

Assembling the acrylic pieces You should have the following pieces:

clear frosted front layer

yellow lamp fitting insert

white middle layer

white back layer

2x white leg retainers

2x white legs with rubber feet attached

6x M3 white nylon bolts and nuts

4x M2.5 white nylon bolts and nuts

Before you do anything, peel the protective film off all of the pieces of acrylic!

Take the frosted front layer, with the side that has the etched lightbulb design on facing upwards and push

through the 6 M3 white nylon bolts from the front. Flip it over and lay it face down.

Now, take the white middle layer (the one without the rectangular cutouts) and place it on top of the front

layer, sliding it onto the bolts.

The remaining white layer goes on next, and the yellow lamp fitting insert fits into the gap at the top.

You'll now need to attach your Pi Zero W to the frosted mounting plate. Place it on top of the mounting

plate so that the header sits in the cut-out, and use the four M2.5 bolts and nuts to attach it, trimming the

excess bolt off with a pair of snips if you wish.

Clip the mounting plate with Pi Zero on into the slots on the two legs as shown in the picture below. The

little clips should hold the plate in place.

Take the two white leg retainers with the cut-out curve at the bottom and slot one onto each leg, and then

place them onto the other layers, so that the protruding parts of the legs fit into the recesses on the back

layer.

Bolt everything tightly together, securing the 6 M3 bolts with the nuts, and trimming the excess bolts off

with a pair of snips if you wish.

Attaching the Unicorn pHAT All that remains is to fit the Unicorn pHAT. Pop it on top of your Zero W's male header, being careful to

ensure that all of the pins are lined up correctly.
