Homebrew Console -Baby Steps

WIN_20160227_12_47_57_Pro

 

This is my second attempt at creating a  game console. This makes use of laser cut palstic parts for the enclosure, it makes use of a raspberry pi and mame.  The game play is not very good. However it feels good🙂.   But I am still learning and after many attempts – I will finally build an awesome game console.  Nividia Jetsons dev board is very powerful but expensive at the same time.  May be I will get one when get a deal somewhere.

Humble Beginnings

This is my first attempt at creating a game console.  It is a PIC based design.  I used an existing kit, studied the circuit and assembled it together.  This  video game console is essentially a microprocessor/ micro controller based circuit with few resistors for interfacing with the video and few switches which work as input to the game console.  You can get an idea on how it is done using  Cornell University Final Projects and  Video game console design course.   Adafruit  industries and  XGameStation provide game console kits.  Meanwhile I will be looking at Ben Nanonote and Open Pandora Hardware design to learn how to design my own awesome little game console.

I will 3d print my own console enclosure for this tiny little project of mine and its going to look awesome!.

Mindmapping with Vim!

 

 

I have used several tools mind mapping before ( freemind, xmind, vym and their likes), but vim is my favorite editor and wanted to do everything from vim itself. To do mind mapping in vim, my solution is to use the DrawIt!  plugin.

Concurrent Android Programming

My brief notes on concurrent programming facilities available in android. I will update it i find something interesting, do comment if you think that I missed something.

The passionate programmer ?

I just finished reading the book the passionate programmer by Chad Fowler ( No! , he is not related to Martin Fowler!) .  Although i do not necessarily agree with all his views. Here are the few take away points for me.

 

  • Try to understand business domain which you are working for ! – I am a typical techie who considered business meetings to be a complete waste of time, from now on i will at least make an effort to understand it better
  • Do not stagnate keep learning something new everyday!
  • “Whoever can be trusted with very little can also be trusted with much, and whoever is dishonest with very little will also be dishonest with much.” – Even if the job is boring and trivial try to do a good job instead of avoiding  or procrastinating.  I was very immature at my first job at Microsoft – this is a key thing!.   Employers do not want a super hero, but some one who can execute well and is pleasant to others.
  • Take some more risks! 

How do i actually write an operating system ?

This my answer to quora query. I thought it is good to archive it here.

 

How do I actually start writing an Operating System?

I want to know the baby steps to be followed. I have read all the introductory articles on http://wiki.osdev.org.
I want to know how do I actually start writing code which can be executed independently of any Operating System. How do I write the assembly code which will enable my machine to execute it directly? What all do I need to learn for that? Also, what are the prerequisites and what are the tools needed for writing an Operating System?
I have read the theoretical concepts of Operating Systems and I have also gone through the Linux source code but I couldn’t understand much.
was at your place initially therefore I hope I can help. First thing you want to do is finalize on what you want to do. Most of the operating system tutorials start with a simple boot loader.  Read the intel manuals and learn them well . I believe it is easier to start with a real mode operating system because bios does lot of work for you .
Answer :
Yes you should have a moderate knowledge of x86 assembly to write an os .

Synfig Animation

I learned to do cut out animations in Synfig. I am all set to make animations using Synfig.

I will finally make the series – The Sandman Chronicles. The idea is simple just like any Indian movie the main story remains the same – the trick is the come up with interesting variations. The world is tormented by a mega cruel villain, all the the super heros in the world put together could not save world. Finally it’s upto Sandman ( the last super hero to save the world), Sandman does something really silly and saves the world.
