This presentation goes over the problems I encountered when creating my device

1. Cheap-o-racer
The struggles of development
By: Karl M. Estabaya Tech Z

2. The short version
Basically, I wanted to create an attachment to my gaming
controller which enables me to play racing games like F1
2017 as if I were in a racing simulator, like the ones in
timezone...

3. The first prototype

4. Cheap-o-cardboard

5. Things to note:
-It only had a steering wheel.
-No gas & brake pedals… yet!
-Main purpose was to prove steering design
works.

6. Early problems
Joystick attachment
When turning right, the band that
attaches to the joystick would get stuck
on the right joystick, preventing a full
turn
Stability of controller stand
Since the stand was not heavy enough and
there was no clamp holding it in place,
it would literally fall apart if I let go
Sturdiness of steering wheel
Since the shaft was made of paper,
it would bend easily under pressure
Just like me lol :)
Considerable bend in
the shaft
Attachment collides with right
joystick when turning
I had to hold the whole stand so it
doesn’t fall apart lol

7. Major improvements

8. Cheap-o-awesome

9. Things added:
-now has gas & brake pedals!
-stronger materials for major components.
-can be set up anywhere!

10. improvements
Joystick attachment
The distance between the band hook and
the joystick was lessened to allow for
more rotational freedom
Stability of controller stand
Controller is secured in place by a MDF
based stand and a velcro strap. Although
not shown in picture, a mini clamp held
the whole stand firmly in place
Sturdiness of steering wheel
The shaft does no bend at all
anymore, and the wheel is secured
in place by an end cap
Shorter band attachment
allows more freedom when
turning
Shaft made of PVC pipe +
end cap makes the wheel
more stable
A stand made of laser cut MDF
+ a velcro strap + a mini clamp
make the whole device very
secure unlike me lol

11. add-ons
Pedal attachment
A hook was attached to the pedal
button, allowing two peices of
string to run down to the ground
and attach to the pedal’s hooks; As
the user steps on the foot pedals,
the pedal buttons are also pressed

12. As nick fury once said:
“No matter what, trouble still comes
around”

13. Newly formed flaws

14. Pending issues issues:
-foot pedal base slides around too much
-steering wheel is too thin and small
-string sometimes unhooks itself from the
foot pedals

15. BUT DAMN…
It works though
Don’t believe me? See for yourself!

16. Cheap-o-Racer being tested during the exhibit
IT WORKS :)

17. Overview of complete components :)
