This is a small monocular/instructable about my discovery, when playing with lenses. The dimension of this small monocular are about 15x10 mm ... but I'm not sure about the magnifying ratio. I would say something about 3-6 times (or maybe more).
Step 1: What do you need...
You need just 2 main items :
1. lens from the small SPY camera
2. lens from a (broken) green laser pointer.
Then you need :
3. something that would hold the lenses together in a fixed distance to get a sharp picture (in my case = washers)
4. glue gun
