One dollar microscope.
What it does
Two dollars microbiological incubator. We want to manufacture and distribute 1 million devices worldwide, so that in even the most disadvantaged areas, there was an opportunity to do microbiological research and educational tasks.
How I built it
Designed simple PCB board with integrated heater in KiCAD. The etching was made in the ferric chloride solution. Then we soldered microcontroller and transistors to PCB. To speak about the code, we were working in Cube IDE studio. We connected all the temperature sensors, calibrated them and made a necessary temperature of 37 Celsius using PID-controller. Our last step was putting all the invention in the box. Then we closed it and waited for our bacteria to grow.
Challenges I ran into
It was to hard to make a homemade PCB board. We had troubles with soldering microelectronics. It was hard to simulate and compute temperature.
Accomplishments that I'm proud of
WE BUILT FULL HARDWARE PROJECT IN 24 Hr!!!
What I learned
We learned a lot of programs for electronic making.
What's next for AESTOUS
Build new version for mass market production. And add new improvements.
