maybe a calculator

MK-61 and stuff

This is a collection of mildly cohesive projects related to Soviet programmable RPN calculator emulation, period-accurate displays and their decent modern imitations.

ИЛЦ2-12/8Л module

Standalone VFD Module

OLED imitation

SH1122 256x64 grayscale OLED is used to fake the VFD look. It's not the real thing, but pretty close.

A part of mk61, it is also available as a standalone minimal project/library: vfd-imitator

MK-61

Based on mk-61 project by sergev and emu145 by fixelsan.

Runs on Pi Pico. Eventually wants to become a usable calculator with buttons and stuff. It will use either of the two displays above.
