My school project. It looks more dangerous than it is.

1. Creating a rollable hand-held
insect zapper
Ardee Guerrero, Tech X

2. Background

3. Fending off the world’s deadliest animal
I wanted to create something innovative and useful on-the-
go against the world’s deadliest creature-- The Mosquito.
And so with this passion project I devised
a way to utilize easily accessible materials to
create a makeshift insect zapper capable of
zapping.

4. Design Process
Portability?
Rollable?
Compact?
Safe?
Useful?
Easy to make?
Cost friendly?
Efficient?

5. My objective was…..
● To create a more compact zapper
● Has an easily rollable wire mesh
● Easy to use and handle
● Better portability

6. Acquiring a commercial insect zapper (racket)
DANGER LEVEL
I bought this insect zapper
near my home at an AllHome
Department store, with
pricing at
P199

7. Dissecting electrical components from Zapper
DANGER LEVEL
With the help of Sir Jason
Alcarez, I was able to dissect
the electric components
safely
The electrical components
have
● 500V Output
● Built LED light
● Rechargeable power
source
● Double (-) channel
Danger Factor:
As mentioned, this
thing is 500V :(

8. Creating coiled electricity channels
DANGER LEVEL
The idea was to create
straight paths for the
electricity to channel
through, thus I coiled wires
around sturdy bbq sticks.
Danger Factor: Alambre is
pointy and caused minor
scratches especially when
coiling.

9. Creating the wire mesh
DANGER LEVEL
Danger Factor:
Poking holes through
the cloth was a little
tricky…. Ended up
poking my fingers a
few times.
Alternating positive and
negative channels on ends,
gaps were a bit uneven for a
lack of care in creation.

10. Creating compact zapper case
DANGER LEVEL
Danger Factor:
Not necessarily a
dangerous task if one
is experienced with
laser cutting already.

11. Adding handles onto zapper case
DANGER LEVELDanger Factor:
The task wasn’t
dangerous to say the
least..

12. Mounting electric components to zapper case
DANGER LEVEL
Danger Factor:
With a small space to handle the
exposed wires, I always had to
make sure the component was
off and immediately mask the
wires with electrical tape.
Electrical component mounted
on, with hole for switch at the
side. Electrical tape was used to
ensure safer handling

13. Connecting the wire mesh to electrical component
DANGER LEVEL
Danger Factor:
If this thing was on while you
tried to connect the mesh,
things won’t look pretty for you.

14. The finished product
DANGER LEVEL
Danger Factor:
The accordion of death.

15. Testing

16. IT WORKS!!
…...But how well does it?
● ROLLS
● ZAPS
● COMPACT

17. Feedback- Mr. Ian Perez (Block A- Tech Y)
● “Maayos naman pagkagawa pero mukhang
delikado nga lang”
● “Kung ako, siguro baygon nalang or
something pero kung mage-exercise ako,
gagamitin ko to.”

18. Feedback- Mr. Leonard Pena (Block D- Tech Y )
● “Gusto ko yung fact na parang accordion
siya.”
● “Cool naman pero baka bigla lang ako
makuryente and ewan haha”
● “Pwede natin to gamitin sa room if ever”
● “Creative yung design”

19. Feedback - Mr. Bon Leif Amalla (Block G)
● “I think barbeque sticks was really smart,
buut it’s still pretty pointy on the ends and
there’s exposed wire”
● “Parang awkward yung paglagay ng hooks
sa dulo, although, functional naman siya so I
guess it’s good.”
● “Yeah I’d buy it if I were to use it during
hiking”

20. The common question…….
IS IT SAFE??

21. Admittedly zapped…...
8 TIMES

22. Things I should improve on
● SAFETY
● Craftsmanship of wires, cloth, casing, hooks.
● Optimization of space inside casing
● Containing exposed wires.
Learning…..
I was very happy with the journey I’ve had with my zapper overall.
There are so many things I’ve been taught to improve on (ehem
safety), but it came out looking like what I had in mind. It is functional
but it calls for many areas of improvement for the design process.I
aim in future creation of projects, I will take into mind these things. :)
