- Yes, you can implement a few logic-like elements without electricity.
- Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. Now, most logic gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).

- [Easy RISC-V](https://dramforever.github.io/easyriscv/)
* an interactive tutorial created by dramforever that introduces the fundamentals of RISC-V assembly programming through hands-on experimentation. Inspired by Easy 6502, it uses a browser-based simulator to let learners observe every step of program execution — from instruction decoding to register and memory state changes — without requiring any software installation or toolchain setup.
* The tutorial focuses on the minimalist yet complete RV32I + Zicsr instruction set, guiding readers from their first simple instruction sequence (addi, ebreak) to more complex topics such as arithmetic and logic operations, branches, jumps, memory access, stack management, function calls, control and status registers (CSRs), privilege levels, exceptions, and even the construction of a bare-bones operating system.
