2+3 LED Throwies
GRAFFITI RESEARCH LAB (graffitiresearchlab.
com) is dedicated to outfitting graffiti artists with open
source technologies for urban communication.
1. Test the LED
Pinch the LED’s leads to the battery terminals,
with the longer lead (the anode) touching the
positive terminal (+) of the battery, and the
shorter lead (the cathode) touching negative (–).
Confirm that the LED lights up.
2. Tape the LED to the battery
Tape the LED leads to the battery by cutting off a
7" piece of strapping tape and wrapping it once
around both sides of the battery. Keep the tape
very tight as you wrap. The LED should not flicker.
3. Tape the magnet to the
battery
Place the magnet on the positive terminal of the
battery, and continue to wrap the tape tightly until
it’s all done. The magnet should hold firmly to the
battery. That’s it — you’re ready to throw (or make
a few dozen more). Throw it up high and in quantity
to impress your friends and city officials.
• Throwies naturally chain
together in your pocket,
making multi-segmented
throwie bugs, which will
also stick to metal surfaces
if they aren’t too long.
• Your throwies will shine
for about 1–2 weeks,
depending on the weather
and the LED color.
Kirk von Rohr
NOTE:
The battery’s positive contact surface
extends around the sides of the battery. Don’t let
the LED’s cathode touch the positive terminal, or
you’ll short the circuit.

Build your own mechanical device to replicate images

2+3 Image Duplicat
or
With a few everyday items, you can make a
pantograph, an image duplicator that allows you
to use one pencil to trace an image while another
pencil follows its path in parallel to draw a copy!
1. Cut out and position strips
Cut 2 cardboard strips measuring 2"×4", and 2
more 2"×8". Place them at right angles, with the
smaller pair on top of the larger (Figure
1
)
.
2. Link strips with paper clips
Cut 4 tiny holes in the strips and slip paper clips
into 3 of them, as shown in Figure
2
. Bend up
the end of another paper clip, as shown, and tape
it to the top of a paper clip box.
3. secure to table
Cut 2 holes in the strips just large enough for 2
pencils to fit snugly and stand erect, as shown in
Figure
3
. Slip the tiny hole at the end of the left-
hand strip over the paper clip that’s taped to the
top of the box, and tape the box to the table.
Place a second paper clip box under your
image duplicator where the 2 large strips meet,
to keep it level. To ensure that pencil A presses
against the paper properly, you can add weight by
taping a AA battery underneath the strip.
Use It.
Place the original image under pencil A, and a
blank sheet of paper under pencil B. Trace the
original design with pencil A. Pencil B will follow
along, drawing the image on the paper.
Experiment with different lengths of strips to
make larger and smaller copies of the design.

Show off your mobile photos and your phone
hack savvy by turning your smartphone into an
inexpensive projector

PHOTOJOJO (2006-2018) was a majestic unicorn
of an online community and photography gear store.
Today the team carries on as purveyors of photo books
and prints at Parabo Press. parabo.press
Slide projectors are great, but outdated, and
digital projectors cost a bundle. Fortunately, you
can make your own.
1. Prepare the projector box
For best image quality, paint the inside of your
shoe box black or tape up some black paper. On
a short side of the box, trace the outer edge of
your magnifying glass and cut it out. Cut a small
hole at the back of your box for your phone’s
power cord. Tape the magnifying lens in place,
and make sure there are no holes to let light in.
2. Make a stand and flip it
Bend your paperclip into a cellphone stand. When
light passes though the lens, it gets flipped, so
the picture from your projector will come out
upside-down. Visit makezine.com/projects/5-
smartphone-projector for instructions on how to
achieve a screen flip.
3. Find your focus
Project onto a bare white wall. Position your
phone in its stand near the back of the box and
walk the box forward or backward until the
image starts to come into focus. Fine-tune the
focus by moving the phone forward or backward
in the box. Set your phone’s photo app to
slideshow mode for a hands-free experience. For
best viewing, turn the screen brightness of your
phone all the way up, put on the box top, cover
any windows, and turn the room lights down.

om Memory Game
Memory is the perfect game. A kid can play it
solo or in a group, it can be easy or challenging,
and it’s educational to boot.
1. Prepare your IMAGE pairs
Cut out matching image pairs from paper, such
as numbers, colors, or words. (Here I used paint
swatches.) Trim them all to about the same size.
2. Cut Your CArds
Find a template for your memory cards — a
cassette tape box, coffee mug, etc. — and cut out
identical faceup sides from your fancy paper for
each card in your game.
Also cut out a facedown side for each card —
this can be from the same or different paper as
your faceup side. These don’t have to be identical,
because they won’t be facing up at the start of
the game.
3. Glue and laminate
With a glue stick, lightly stick your faceup and
facedown sides together, then stick one memory
game image on each facedown side.
Laminate your cards for durability, or take them
to a copy shop to be laminated.
Use It.
While simple identical color matches work well
for a memory game, consider tweaking your
game toward a specific educational experience
or a specific kid. Try matching colors with color
words, for instance, or pictures with Spanish
words, or math equations. Keep your kids
guessing!
