Why is this happening🧐?

Dear Foldscope community:

My foldscope and a few of my students’ make a shivering movement probably due to something dealing with the magnetic coupler. Can you help us? To better understand what I refer to, I have uploaded this video about a group of enchanting protozoa known as “bell animalcule” Thanks in advance!

    Hi Cristina:
    I spoke to @Manu and @Jim about it some time back and it seems to have to do with something called the voice coil. I have noticed it in the new iphones and pixel 3. Manu tells me that the system stabilizes after the initial sputter. Perhaps they may have made more headway on how to fix/prevent this.

    Hi, Laksiyer! Thanks so much for your comment. It happens, as far as I know, with my IPad and a few iPhones. I will tell my students to pursue trying to see if they do stabilize. Thanks again.
