Let's begin

To start making the camera, Sourcing for the right parts is crucial . For the "backbone" of the camera, I made use of the following
1. PVC strips of various sizes. (Dimension will be provide for those interested)
2."main stem" of a dropper for its objectives. (I will send the cut version to you if you are making one)
3. And a plastic rod smaller in diameter than that of the objective made in step 2. For its Zooming objective

And next decide on the dimensions of the final product.
