Simple Smartphone Microscope - version with electronics

This is the repository for the simple electronic version of the Smartphone Microscope.

This microscope and the code for the ESP32 is a work of students from KL-Gymnasium in Erfurt. It was updated to the v3 version by UC2 core team.

Devices' features:

  • Simple microscope for smartphone imaging
  • Manual alignment helps to understand the principle of a microscope
  • Teaching the basics of electronics that are needed for more advanced setups

Parts

The Bill of Materials is always the most up-to-date version!

Modules for this setup

Name Properties Price Link #
Baseplate puzzle - 5€ Base-plate 8
Module: Z-Stage - ?? € Z-Stage 1
Module: Sample holder - 5 € Sample holder 1

3D-printing

To acquire the STL-files use the UC2-Configurator. The files themselves are in the RAW folder. The module can be built using injection-moulded (IM) or 3D-printed (3DP) cubes. Choose the APP_Smartphone microscope for this one.

In the end it should look like this (UC2_v2 cubes displayed):

Electronics (for dummies)

Don't have much experience with electronics? It's actually really simple:

  • When using jumper wires you can avoid soldering.
  • LED array - 3 wires + 2 wires for the button

  • Z-stage - 6 wires + motor connection + 2×2 wires for two buttons

  • Power the ESP32 simply with microUSB cables.
  • And it works just like that ;-)

Code

In the CODE folder you find the code for both the LED array and Z-stage.
