Trying out a new light source for our foldoscopes!

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!

    Fantastic hack. How much does the light cost?

    Thanks for sharing this hack. It’s wonderful.

    Also; as an important safety note – whenever anyone in the community tries a new light source – just check its lumen. If the light is too bright to look at directly – it’s too bright for your eye. Better to start very dim and slowly increase intensity.
