Neptune and Beyond

Neptune I in all its glory is mostly a simple Moore state machine and was (mostly) a success. I say 'mostly' because most of the code, in retrospect, is very messy. I would love to take the time to rewrite it (which I actually might do). It is slightly tedious to do because it can get very hairy in certain modules, especially the core module which instantiates every other module in the system.

Neptune I: Introduction

Sometime in the third quarter of 2013, I ran into a YouTube channel, called madmaxx. He was working on quite an interesting project, an 8-bit computer made up entirely of basic gate level CMOS Integrated Circuits. It caught my attention.

Serial Displays

One of the most satisfying and fun parts about designing Neptune I were the displays for the front panel. They were simply thirteen seven segment displays, which seems simple enough, until you realise that each of those displays requires eight inputs to run. Unfortunately, I could not afford to have (or possibly think of controlling) 104 outputs just for the displays.

The Human Brain and Reality Simulation

The neural simulation above contains 16,777,152 neurons and 2,142,113,089 synapses. That's huge, but it's not even remotely close the number in a real human brain. That squishy thing sitting above your face has hundreds of billions of neurons and hundreds of trillions of synapses that unite into complex connections which make everything possible.

The Singularity is Boring

The 'singularity' is boring, very boring. Let me clarify, technological singularity is boring, very boring. So boring, that the very boring picture here is perfect. So boring, that the word 'boring' has now been semantically satiated.

Human Behavioural Psychology

Wonder what this represents. This one dates almost to about two years ago, probably around the time I started to first indulge in Psychology. I don't really have much formal knowledge in the field itself, but it outlines what goes on in my mind well.

Binary Number System

If you don't understand the joke above, I recommend you read through the post. As I'd like to keep this series as detailed as possible, explaining binary really quickly wouldn't hurt. Binary is a number system, just like the decimal number system that we use everyday.
