Do you have any pictures of the whole device? What is the overall size? How long does the watch battery last? I would assume quite a while since it is an LED

- tedsanders 13y agoIt's like 6" by 3" by 1/4". You can see the size in the TED talk or on the website: http://www.foldscope.com/#/scienceeducation/ http://www.foldscope.com/#/scienceeducation/ Honestly, I'm not sure how long the battery lasts. I've mostly worked with the versions that have no backlight (to use them, you hold them up to a lightbulb or to the sun).
