3c. Dab a bit of solder flux in this joint (Figure
P
),
then heat both the rod and the solder pad with the
soldering iron, and patiently wait for the solder to
melt.
3d. Double check that the filament is aligned
well enough (Figure
Q
). Remember to be kind to
yourself — you're making a unique object!
3e. Do steps 3a–3c for the other two filaments,
positioned on either side of the center filament.
You might consider using heat-resistant Kapton
tape to help you align both sides (Figure
R
). Keep
going, you’re doing great!
3f. At this point, you can test that your solder
joints are good and the orientation is correct,
using alligator clips and a 3V power source. Here
I'm just using two alligator clips connected to a
2032 coin cell battery to make sure each filament
will light up properly (Figure
S
).
4. SOLDER THE BOTTOM RING
4a. Using the same incredible maker tenacity
you’ve been demonstrating this entire time,
carefully position the bottom ring so that the front
V touches the ends of the LED filaments and the
backside touches the battery holder’s solder pad
(Figure
T
). This can be tricky; again, take your
time and try not to break any of the filaments.
4b. It’s OK if there’s a small gap between the ring
and the battery holder pad (Figure
U
) — you
should be able to fill this gap with solder. Dab
some flux on both the battery holder’s solder pad
and the brass rod (Figure
V
). Heat up both the
rod and the pad, and apply solder.
4c. Bend each filament’s solder pad outward
and ensure that they stay inside the ring (behind
the brass rods). Three more solder points with
more flux here, and you’re done (Figure
W
)! You
can use some fine-grit sandpaper to smooth
any pointy bits, and steel wool to get the brass to
shine.
Now you can put the battery in the holder and
see your creation glow!
SCI-FI SPLENDOR
This ring is elegant enough for a glam night
out, but I've also worn it casually around my
workplace. A single 1220 coin cell battery should
last the entire day — my last one went 15 hours,
so I had to pop out the battery because I didn't
want to waste the energy when I went to bed.
I love being able to incorporate a bit of glowy
magic into my everyday, and I hope this guide
helps you to make a little retro-futuristic, sci-fi
inspired magic of your own!
