Using Distance Sensor in Arduino (HC-SR04)

There is a component which can be used to measure distances by emitting ultrasonic wave to an object and calculating the time it takes for the echo to come back (from the time the sensor emitted the ultrasonic wave. Generally, the echo goes back to the sensor at two times the distance (First distance is from the sensor to the object, second distance is from the object back to the sensor). The speed of sound is calculated at 343 meters / second. If you recall your Physics class in intermediate school (or even college), you know that: velocity (v) = … Continue reading Using Distance Sensor in Arduino (HC-SR04)

El Chavacano: Lenguaje del mi lugar de nacimiento.

I have always been used to hearing our local dialect in my beloved city of Zamboanga: I was born and raised there basically. However, having been there for more than two decades, I had not spoken the dialect fluently until I stayed in Makati City in 2008, where I stayed in a boarding with my fellow Zamboangueños. I had to equip myself with the accent and some hondo palabra (deep words) to be able to adapt my fellow boardmates and other Zamboangueños whom I would be meeting then. A large percentage of Chavacano’s words came from Mexican Spanish, with influences … Continue reading El Chavacano: Lenguaje del mi lugar de nacimiento.

The shots below are pictures of these hills which I took myself on top of another hill. Here they are: Continue reading Chocolate Hills

Aerial View of Taal Volcano

We were headed to Bohol Island, part of the Bohol Province in the Visayas region for an official business trip. As the Philippine Airline took off from Terminal II of the Ninoy Aquino International Airport in Pasay City, Philippines, I was lucky to have a view of the Taal Volcano from air without much cloud to cover the “smallest volcano” in the world. I never doubted to take shots of the said volcano. Images below are the the pictures of Taal Volcano, minutes after the plane took off the terminal in NAIA 2.

Manila Bay Dusk

I always wanted to take a photo of the sunset via Manila Bay perfectly. I mean I need to see the sun set before my eyes on the horizon and capture that moment. Whenever there are instances I feel that the day would be great and that clouds will not be filling up the horizon part where the sun sets, I would take time to go to MOA (Mall of Asia, Pasay City Philippines) and wait for the right time to take photos of the moment. However, never in my time that I was able to take the “perfect sunset.” … Continue reading Manila Bay Dusk
