Maker Faire Rome 2023
GALDEANO, DIY Calculator with simbolic math
The heart of the machine is an esp32 with 4 Mb of SPI RAM. The PCB is a custom one, as it is the keyboard. The display (320x240) is an ili9341 with a touch sensor (resistance). It runs a custom micropython distribution with LVGL graphics with the math engine (Eigenmath) as a module. The program runs in the data partitions and it is easily customizable and extensible.

I have been working in IT for 30 years, now I work for the public health services in my region. Electronic has been a hobby for me since I finish my science university studies, but now my children have grown enough to allow me to create things.
