BitCard.4

Introducing the 4-Bit Card Computer from SuperCon!

Origin
Originally created for the 2022 Hackaday Supercon, is a hands-on learning tool designed for enthusiasts of retro computing and microarchitecture. Featuring a sleek black design, and soldermask with white and yellow silkscreen, this badge isn’t just eye-catching—it’s a fully functioning 4-bit computer emulator.

Developer
Designed by Voja Antonic, with code name Voja4 Badge, it serves as an interactive way to explore the fundamentals of computing. It's built around the concept of a fictional 4-bit computer, the "Voja4," offering users the opportunity to learn by doing—through programming, experimentation, and discovery.

What makes it special?

• Interactive Programming: Enter programs by hand, like the classic Altair 8800, or use a serial port for faster input.
• Simplicity at its Core: The instruction set architecture (ISA) is minimalistic and beginner-friendly, making it ideal for those eager to understand the basics of computer operation.
• Full Transparency: Witness the inner workings of the "Voja4" in real-time, from data processing in the ALU to memory operations.
• Powered by Emulation: A PIC24 microcontroller brings the Voja4 to life, enabling seamless operation and an engaging user experience.

Whether you're a seasoned hacker or just starting to explore computer architecture, the Voja4 Badge combines learning, fun, and nostalgia into one unique device. Dive into the world of 4-bit computing and experience the joy of programming with the Voja4 Badge!
