this is a really simple lens you can put together to get nice macro shots for any mobile or tablet camera. i have seen this a few times before but i have seen ways that could damage the device or just take to much time.
Step 1: Materials and Tools
the materials you will need are:
clothes line peg (plastic)
engraver/drill with small drill bit (size of lens)
any circular cutting tool
For this I used an old engraver I had in my room
Step 2: Getting The Lens
all we need from the laser pointer is the lens. so pull it apart and carefully pry out the lens. It should only be something like 5-8 mm wide. Before we move onto the next step try putting the lens over the camera and holding something just above the lens until the picture is focused, this is hard because even the slightest movement can move it. I noticed as i held it above the lens it would move every 3 quarters of a second or so, I realized this was just my heart beat which slightly moved my fingers.
Something else I noticed was that because this lens was from a laser pointer the focus point was really small. This is because the lens was made to focus the red light into a tiny beam and not for photography.
