cheap microscope to help against malaria

Looks promising for malaria blood testing. They claim to make this product cheap. Could be, but to me looks not easy enough: phone disassembly, Motorolla specific phone (= to by an extra phone), looks like use only one type of light, automated sample glass movement.

It is hard to judge, maybe all this complexity is still needed (compare to 1$ solution), however, I'll make my own 10$ idea:

Passive lense adapter for 1-2 similar most popular phones on the African market (remember about malaria).

Two holes: 1 for a camera, 1 for the flash. On top sliding color filters.

Flash reflectors spread the light from the phone flash more evenly.

Fixed optimized for the distance lens (or several of them) - the phone is pressed firmly to the top.

On the bottom: slot for sample glass (or film) with a hook to rotate the sample.

The glass is on the angle to make a slight 3d rotation.

The idea of work: A person with a popular not expensive android phone put the phone on top of the adapter, the semple to the slot. There are 2-3 positions of sample rotation (bottom) and 3-4 filters. The app asks to make 6-12 pictures to the cloud (more pictures, much easier for an AI algorithm to detect; color filters create better spectrum like analysis), but I think pre-trained neuron network should work autonomously (with send to the server as an extra option).

1 picture rotate filter, another rotate position... step by step 12 pictures.

As a small analysis. There was another project for malaria (supported by Gates fund):
