The Badge.Team mascot
In summer 2020, I started volunteering for the MCH2022
That is when I realised. There is no way to perform transformations. There isn't even a way to draw a triangle!
So, I got to work creating some better graphics for them. And now, for the MCH2022 badge, I was asked to write the graphics stack.

GR8CPU Rev2, an 8-bit breadboard computer.
GR8CPU is my project to build a fully functional computer on breadboards.
The first version i built, GR8CPU revision 2,
has easily over 600 wires, 74 integrated circuits and 79 LED lights. It is an 8-bit architecture with
simplicity and processing power in mind. The CPU has access to 256 bytes of RAM,
and i have written a fully functional
As of now, I'm working on building my second one, GR8CPU Rev3. The first CPU was loads of fun to work on, but my ambitions are higher: with 65536 bytes of memory, improved arithmetic and a much higher speed by design, this CPU is a contender for the most complex breadboard CPU ever made.
Whereas the flagship program for GR8CPU Rev2 is a game of
GR8NIX, first time running a program.
GR8NIX is an operating system inspired by Unix,
a simple multi-user, multitasking operating system made in the 1970s.
Modern operating systems based on unix's ideas include Linux,
MacOS and Android,
GR8NIX is written in assembly, for GR8CPU Rev3. It is made of over 2000 lines of hand-written assembly, totalling over 5 kilobytes and counting.
