Here’s a Fubarino contest entry for all those homebrew computer nuts out there. [Danjovic] modified an NTSC/PAL display adapter to show an ASCII version of the Hackaday logo when his board first boots up.
The build is based on [Daryl Rictor]’s video display Adapter intended for use with homebrew computers, microprocessor projects, and any other minimalist digital setup that needs an NTSC or buddy video display. It’s a surprisingly easy circuit, made of a few logic ICs and an ATmega8.
[Danjovic] modified this video display adapter with an easter egg: if one pin on the ATmega8 is shorted when the board is powered on, a neat Hackaday splash screen is displayed for several seconds before falling back to the stock display of a blinking cursor. [Dnajovic] converted the ASCII Hackaday logo with the help of a short Python script and loaded it onto the AVR with a small firmware change.
Video of the boot screen in action below.
This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
