DIY Airsoft Chrono [PC-based]

Chrono or Chronograph, the term used by Airsofter and Paintball players to refer to the device that measures the muzzle velocity of firearms. This is also called MVMD, short for Muzzle Velocity Measuring Device by the British Army. Muzzle Velocity is the velocity of the bullet as it exits the barrel of the firearm.

A year ago I was an active Airsofter in Iligan who's more interested in modifying and improvising AEGs (Automatic Electric Gun) rather than playing airsoft. I have made my AEG susceptible to high current burns by using locally available MOSFETs. I have improved velocity by replacing cylinder gaskets and spring. I have increased the rounds per minute by altering the armature windings of the drive motor. And most of all, I have made my own cheap alternative PC-based Chrono.

I have posted an artivle before that details the development of my chrono but unfortunately the online forum was hacked/deleted by webmaster of proboards.com due to some violation in the contents. So, …

Handcuffs

It's been almost a year now since I've been writing Java codes since I was deployed to my current project. I used to write .NET C# codes for almost 4 years back in the academic world. Just yesterday, I was given a change to apply my .NET skills again to solve a real-world problem and fix a bug in a special browser application. In my experience in Java, I have been using "throws" keyword when writing a library to require the caller to catch exceptions that could possibly occur in the library. This feature is called "Checked Exceptions". But, I was surprised to find out that C# does not support this feature. So, i did a few searches on why did'nt Anders Hejlsberg, the lead designer of C# Language, didn't include this when in fact I find it useful when I was writing in Java. Then I found this interesting link which describes the reason behind this.

The converstation in the article state clearly that the designer decided not to include checked exceptions…

Journey to a Smoke-free Life

It's been a week from now from the very day I decided to quit smoking. It was not easy but I made it this far. What made me decide to quit is that when I noticed that the system is failing, I should do some precautions. I call my body a system of systems. I just had a cough, chronic sinusitis and allergic rhinitis for two(2) long weeks. It's not supposed to be like this long (2 weeks) before it heals on its own. I was thinking maybe I'm getting old and I need to change something to the routine to fit the current state of the system. So I tried changing flavors, from Beer to Cocktails, from more rice to more veggies, and from smoking to not. Two days after, my observation was that the system is now healing on its own. Maybe I am right. Until then I never get back smoking and I am hoping I can do this until I reach a state of a smoke-free life.
