Fubarino Contest: Splash Screen On System Reset

logo

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 PAL video display. It’s a surprisingly simple 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!

  2. Both the original design from Daryl and the board from Danjovic have parallel inputs, not serial….
