DIY LED Tester

This is my first attempt on documenting an instructable
I like to build thing's from salvaged part's which often include led's,switches , resistor's , capacitor's ,etc. etc. The problem i often face with those LED's is most of them are not working,so i decided to build a portable LED Tester.After thinking alot on what material should be used i decided to give it a try with plexiglass (coz i got a scrap piece of it for free)

Electronic's

-3v Li-ion battery
-battery holder (i salvaged mine from a motherboard)
-LED(optional)
-On/Off switch
-wires
-Solder wire
-Soldering iron

For construction of the casing
-Plexiglass
-Hacksaw
-Permanent Marker (for marking,not necessary to use permanent marker)
-Scale
-Instant adhesive
-Files(for shaping the plexiglass)
-Paint
-Xacto / Scalpel 

Most of my material's are taken from here and there,reusing  them to decrease the cost of the build
i know the pic's suck & are blurry but i badly need a good camera  :( .My parent's won't agree to buy one ,they keep telling it is not required.

For making the casing start off by marking the shape on the plexiglass with a pencil , when you are satisfied with the shape & size darken the lined with a marker.Pick up your cutting tool,if you are better equipped then good ,for me it is the old fashioned way.....with a Hacksaw.
If you are using a hacksaw then go with 25-30 strokes per minute,try and maintain a straight cut.
After you are done with cutting file off the rough edges.


The Dimensions i took were:- 5cm x 3.5cm & the thickness of the plexiglass was 5mm

Glue all the side pieces

The wiring for both the led's are done in parallel ,
