I’ve loved my Foldscope, using it with the small magnifying light source as well as holding it up to the natural light. However I wanted to find another lightsource that would be:
1. battery operated
2. dimmable (and not too bright for your eyes)
3. fairly cheap, yet easy to find (!)
This past week I tried it out in my course at Bard College in NY, using a battery operated LED tap light I bought at a local hardware store (I purchased a 6 pack, plus batteries and remote for $34, but it was not on sale, and I suspect they can be sourced more cheaply).
It is remote control operated, has brightness flexibility, and with a flat surface, I could easily attach a magnetic coupler to the light. The light could also be dimmed to 10%, and gradually raised, if needed, as could a filter be taped onto the surface.
Students found it easy to use, and I’ll continue to work with this hack in the future!
