  • Flea Systems - Flea86 [2012]
    This is an entire PC-compatible single-board computer implemented with an 8051 microcontroller (!) running an x86 emulator.

    I've been able to find very little about the Appotech AX-2005 System-on-chip, just the first page of its datasheet (it runs at 125Mhz):

  • Gigatron – TTL microcomputer
    This TTL computer looks like an interesting design:

    - It implements an 8-bit RISC CPU with an 8-instruction CPU using a surprisingly small number of chips: just 36 standard TTL chips, a ROM, and an SRAM chip.

    - The VGA output is generated entirely in software with no additional graphics hardware (other than a resistor DAC). User code runs only during the hsync and vsync periods.

    - The ROM kernel takes care of all the VGA timing and runs a virtual machine which presents itself as a 16-bit CPU and includes an interpreter so programs can be written in a high level language.

  • Nixie Tube Clock | 0x7D.com
    A very nice project report on the design and build of a simple Nixie tube clock including an unexpectedly in-depth section on the design of the custom flyback boost converter. The tubes are driven by individual transistors, controlled by an stm32 uC, powered and programmed over USB-C, and housed in a custom machined stainless steel case.
