A very small Ben 10 Omnitrix

I have had this toy for weeks and since I have some free time tonight, I decided to open it up. I was fascinated with this toy because of its design, nevermind if it resembled an Onmitrix. If you look at it long enough, it could be a limpet mine, a door security seal, a time-bomb, some equipment you can attach to another prop via magnets, etc. The main aim is to open up the toy and see how much space it has inside it. Not only that, how much plastic I would need to carve way if I needed more space, especially if I wanted to put in bigger sized batteries in there.

So what will I modify the toy to be? Only time will tell but definitely, I want to have lots of green LEDs in there!

So, this is the toy, which measures about 2½" x 2"

When I removed the green lens, there is only 3mm depth
so this means I would have to remove the plastic more
as a normal circuit board is about 1.6mm thick and
a normal LED is anything from 1mm to 7mm tall. I
am suprised the green LED is so bright!

The toy opened. Although it uses a small loudspeaker,
but by housing it in a small resonant chamber and
with some slots as speaker grill, the sound is quite
loud. This design is very similar to the Playmates
toys for Star Trek. Unfortunately, if I want more
space, there is a LOT of plastic I need to remove.

Minutes after I closed it back, Kristine came over and
started to model the toy for me.... ha ha ha ha ha
