This Hackaday article details likeablob » 's Denki-Kurage, a desktop electric jellyfish project inspired by Bladerunner. The project utilizes a Cheap Yellow Display (CYD) – a small touchscreen with an ESP32, USB, and SD card socket – to create a visually appealing and interactive desktop piece. The jellyfish’s "swimming" is controlled by adjustable current, adding to the aesthetic. The build is straightforward, involving flashing code via a web flasher, 3D printing a frame, and attaching the CYD. It's a fun and whimsical take on the CYD platform, moving beyond typical control panel applications.
The article details how the Intel 80386 CPU implemented backwards compatibility with 8- and 16-bit software. It explains the use of SRAM for register storage, a triple-ported register file, and a 'shuffle' network to handle different bit-width reads and writes, including interleaving the bottom 16 bits of the registers.
