So we have an OpenVR headset now. We will need some stereoscopic content to enjoy OpenVR. There isn’t much you can do without setting up some drivers and softwares.

You can watch 3d stereoscopic videos or movies but that will be nowhere near as immersive as a head-tracking enabled 3d game.

So we need “3d”, “head-tracking enabled” games.

Let’s see what options do we have for rendering games as side-by-side 3d;

OpenVR – 2 : Software

In an earlier post, I mentioned story of OpenVR project. I will guide you through building an OpenVR headset, in this post.

OpenVR hardware consists of several parts; electronics, case and lenses.

Before we begin building an OpenVR, let’s make a list of requirements.

How I got interested in Oculus Rift?

I can’t say I’m a huge gamer. I do enjoy playing games though. But when it comes to innovative *HCI devices, I’m very enthusiastic. That’s how I got really curious about experience offered by Oculus Rift, a total new way to experience reality, in a virtual world.

Curiosity alone was not alone for me to buy a Rift though. So I postponed buying a Rift for some time.

I’m building and flying custom multicopters. I was using a monitor to display camera feed from my quadcopter. It is nowhere near as immersive as flying it with a video glass. So I realized I needed a video glass to fly it *FPV.

FPV glasses cost around 150-300 $ and the highest *FOV is only 40 degrees. Compare that with 110 degrees FOV of Oculus Rift and 300 $ price.

It would be plain stupid to invest in FPV glasses. So it was now clear that I needed a Rift. It could serve me as FPV glasses, Gaming Goggles and for all other cool things you can do with a Rift; like watching a 3D movie.

Maker’s Dilemma : Buy or Build?

As a maker, you’ve got two options to acquire a new gadget. You can just buy it, or you can build it from scratch!

SmartWatch 2.0 – Just Open Sourced!

There has been a huge increase in demand for smart watches in last couple years. There are many options in the market, yet there is no open source alternative, neither any initiative. I always loved open-source software & hardware thus i decided to turn my smart watch project into an initiative for creating a smart watch alternative for all the other options out there in the market.

Both software & hardware design is very primitive so far but I am totally sure it is not far that we have fully functioning smart watches on our wrists that we can hack, modify & re-design for our every need.

Imagine having your computer, smart phone and your tablet on your wrist, SmartWatch is more than that because it packs all that computing power into a wristwatch form that you can actually wear in daily life. It is a dream waiting to become reality. Let’s make it!

Arduino Ethernet Shield has arrived.

Hi fellows,

Last week , my delivery – the arduino ethernet shield – from Farnell has arrived. I was totally excited about it but i didnt have much time to play with it last week because i had visa exams.Finally , yesterday i had some time to play with it. I tested some of the example source codes on it and i have to admit that it was dead easy to set up & get to running.There is a plethora of source codes available for the shield , not just source codes but also lots of demonstration videos of what others made with it.This – The Sharing – is one of the reasons i love Arduino Community. A community of makers and enthusiast those help each other . It is a community where imaginations come alive and get in touch with the physical world in a collaboration and im grateful to be part of it :P

Update on the Open Source Bluetooth Watch Initiative

It has been more than month since Open Source Bluetooth Watch Initiative first announced.There has been some improvements.Hardware side of the project completed.But there is a lot to do on the software side to make it a nice developer-friendly watch.So i started programming an API for the watch.But this last month has been very very busy for me.But still there has been somethings done.

Hardware Updates :
5 pushbuttons added for navigation.
Tilt-Sensor added.

Software Updates:
I designed watch UI on top of Vertical Screens called Widgets.In these Widgets, we’ve got buttons , labels etc.

There still some lacks & issues to solved.As soon as i have some free time i will work on those and release source code with Android & Maemo Apps. to talk to watch.If there is anything about the code that is bothering you please dont hesitate to comment or contact me :) .Suggestions are welcome.

Here is a scheme of the Class Structure:
