I. Abstract

A. Purpose

The purpose of our project “Virtual Vernier Calliper” is to measure inner, outer diameter and the depth of an object without the presence of the real vernier caliper with the use of your own computer.

Here are the following samples:

Nokia C3 Cellphone (length): 27cm

Nokia C3 Cellphone (width): 53.95cm

Cherry Mobile Flare Cellphone (length): 59.30cm

Cherry Mobile Flare Cellphone (width): 30cm

MyPhone Cellphone: 52.50cm

Ping Pong Ball: 16cm

CD Case: 66.80cm

QCPU library card (length): 42.85cm

QCPU library card (Width): 30.30cm

Sim Card: 11.85cm

Cellphone Battery Cm-9b (length): 30.60

QCPU I.D (length): 40.30cm

QCPU I.D (width): 25.50cm

Mongol Ballpen (length): 67.65cm

Mongol Ballpen (width): 6.10cm

One peso coin: 11cm

Five peso coin: 12.25cm

Melvin’s Ring (radius): 7.45cm

Baller (radius): 28.20cm

Sharp Calculator (length): 68.65cm

Sharp Calculator (width): 38.05cm

Pencil Sharpener: 24.65cm

Compaq mini net book: 91.5cm

A4tech Mouse (length): 54.50cm

A4tech Mouse (width): 23.50cm

B. Procedure used

To make our project “Virtual Vernier Calliper” possible, we research on how to use a vernier calliper and our professor taught us well. We search images in web as a reference and use our programming skills on using Visual Basic Studio in our Programming 3.

C. Result

The result of this project is we emulate a calliper on a monitor you just put your object on the monitor of the computer then measure it, and the advantage of it is you don’t need to solve the exact measurement when the main scale is not a line at the secondary scale of the Vernier calliper.

D. Conclusion

I therefore conclude that this project “Virtual Vernier Calliper” will help us...
