While I was in Atlanta, my friend Matt Refghi spotted this little frog in one of the plants in the backyard. I then jumped to my camera and started taking some photos.

This little specimen turned out to be quite cooperative as a subject.


 Take a look at the pictures on my Flickr:

It's been three years that Matt Refghi has been trying to get me to go to Dragon*Con in Atlanta, Georgia.

Matt went to the two last ones and wrote up some nice posts about the top ten costumes at Dragon*Con 2011 and the top 5 costumes at Dragon*Con 2010.

Well, I have the pleasure to announce that I will be going to be part of this crazy feast! After having had a small glimpse of what Dragon*Con might be by attending the Montreal Otakuthon 2012, there is no way I will miss out on this for another year!

As the start date of Dragon*Con 2012 approaches (August 31st, 2012), the nights seem to get longer with all the enthusiasm building up!

You can expect tons of pictures to come out of it! I will try to post pics at the end of every single day, and keep you informed on what costumes to look for!

Take a look at the pictures taken during Otakuthon 2012. There were some pretty good costumes out there in this Con in Montreal.

If you are planning to go to Dragon*Con 2012, let me know!

If you are interested, I suggest you head over to the Dragon*Con 2012 registration page as soon as possibleas their "NEW limited number of Saturday Only passes" will only be available through the Dragon*Con store for 50$ until August 17th (tomorrow!).

So nowadays almost everything can be done with an iPhone.

I found this great app, Mobile Mouse Pro, that lets you use the iPhone as a computer mouse in the air. It achieves this by using the accelerometers for movement and its touchscreen for buttons and scrolling. You can also configure it to use the screen as a trackpad instead. You can easily access a complete keyboard by simply flicking down your iPhone.

While there is a free version, this app is brilliantly conceived and it is definitely worth it to buy the premium version.

As a collective birthday gift from my girlfriend and my brothers, I got an electric RC airplane, the Apprentice 15E RTF with the Spektrum DX5e Radio included. A pretty big one, I should say. I had to wait for about two weeks before receiving it, and then an extra week and a half before being able to fly it outside due to winds in excess of 12 km/h. These are pretty calm winds, although when starting to pilot RC planes, it is highly recommended to do so in absence of winds.

So I did some homework. I purchased a model airplane flight simulator and practiced controlling the simulated plane for a few hours...aka all night long! I was so excited about piloting it perfectly the first time. The only inconvenient was that the controls were routed to keys on the keyboard, as I did not have a dual stick gaming pad, nor any USB transmitter dummy. I recently found out that the DX5e could actually be plugged to the computer through the microphone port. Yes, the microphone audio jack! This was a bit of a shock to me at first, but come to think of it, what the transmitter sends to the plane is nothing but a signal. You see,  the only difference between the signal it actually emits to the plane (high-frequency signal like wifi devices use) and the one it outputs to the computer is that one is probably down-sampled to a frequency within the human audible spectrum (low-frequency signal under 22 kHz). This "scaling down" allows the signal to be audible to a microphone. The higher frequency signal will allow a longer range of transmission and facilitate some common issues with radio telecommunications (thus using a 2.4GHz frequency spread spectrum technology). This is how I understand it and I may be wrong, in which case I would gladly appreciate being corrected, as I prefer knowing facts as they are, and not simply as I believe them to be.

Anyhow, back to the main point.

As soon as the winds got below 6 km/h, I headed out to the closest baseball park I could find. Was I ever excited to make it takeoff and get it up in the air! And so it was, I was able to pull off a perfect takeoff and get it to fly over the baseball field a couple of times, and even make some loops and rolls. But then came the moment where I was starting to get stressed about the landing part of this adventure.

The wind was calm, without any gusts to worry about. The baseball field was pretty small after all, I'd have to fly in pretty low over the park adjacent to the baseball field, but not too low since I'd have to fly over the fence surrounding the field. At the same time I had to make sure that the plane was facing the wind straight on while landing, reducing the throttle to a minimum, shutting it off and just gliding to touch down. Everything went great, a little bumpy yes, but great for a first landing. My first flight was a success!

Having gained some confidence with this first flight, I decided I should take it on a second flight.

It went pretty much the same way the first flight did. Good takeoff, a few tricks, a couple laps around the neighborhood, going high up in the air, lining up for landing, reducing speed...

And then... a gust of wind followed by a counter-wind or something of the sort. Basically, there must have been a gap of wind that made the plane drop in altitude very rapidly. My reflex was to make the plane go up to gain a bit of altitude because it was still going too fast to touch down. Big mistake, I pushed UP on the elevator stick, thus making the plane peak down towards the ground. Fortunately, this is a foam plane and the foam absorbed most of the impact without breaking. The only casualties were the spinner cone, the motor mount and a few plastic clevises that were holding on to the ailerons and the wheel pivot. Gladly, it cost me only about 20$ to order a new set of the damaged parts. The battery itself, a LiPo battery, got bent slightly, therefore requiring to be quarantined for a while, as this type of battery is extremely delicate and is known to explode and burst into flames quite easily.

 It has now been a couple of weeks since this incident and I have finally received the replacement parts. In the meanwhile I have been practicing piloting the a similar model on the computer with my DX5e controller plugged into my sound card. The software I am using to accomplish this is SmartPropoPlus with PPJoy joystick driver and ClearView RC Flight Simulator. SmartPropoPlus is a driver that will listen to an audio port and decode the signal that a radio controller is sending to it. It then converts that signal to an emulated multi-axis parallel port joystick. The PPJoy (parallel port joystick) driver then takes the signal on the emulated parallel port and interfaces in windows, allowing to specify which channel controls which axis on the virtual joystick in windows. The RC Flight Simulator is then able to use the virtual joystick as a controller. Keep in mind that this so-called virtual joystick is being commanded by the external radio controller through the audio signal. I reckon this might not have been the best explanation ever, but when you understand the complexity of what is going on behind the scenes... it is simply fascinating! (I will soon post the links to the sites with instructions for installation)

I can't wait for the next calm, windless day!

Well I am now back from the land of kangaroos, koalas and vegemite, but most importantly, the Great Barrier Reef, the largest reef structure on this planet. I am an avid Advanced Open Water Diver and love taking my camera along with me whenever I dive.

Although the stay in Cairns was short, compared to the time spent in airplanes and airports, departing from Montreal adding up to over 28 hours (and that was only one way!), the rewards were indescribable! The conditions were not ideal for visibility underwater. It was quite windy during the few days that we were there, and the water was quite agitated, thus lifting up particles that would on a normal day be deposited on the ocean floor. But at the end of the journey, this is the GREAT Barrier Reef, and it just makes it all worthwhile!

We stayed on a liveaboard boat for 3 days and 2 nights. These were 3 days that could not possibly pack more dives than they did. I had the opportunity to dive ten times during these three days, and for about 45-50 mins each time. What limits the number of dives one can perform in a single day is the amount of nitrogen that your blood accumulates as you function in a higher pressure environment. And the deeper you go, the faster it accumulates and more time is needed in-between dives to eliminate it.

The underwater camera I have at the moment is a beginner level camera, the Sealife DC800, with a beginner level strobe flash, an Intova ISS2000. Nonetheless, I managed to take a few good shots and would like to know what you think of them.

P.S.: If you want to take a look at the not so good pictures, take a look at my picasa web album!
