Ateneo Physics Department now has an Electronics Laboratory at the Science Education Complex

Electronics Laboratory at SEC C 107

by Quirino Sugon Jr.

At Science Education Complex Building C Room 107 is the Physics Department’s new Electronics Laboratory. The entrance of the laboratory is near the Mateo Ricci Study Hall.  But the normal way to the lab is through SEC C 106 via a narrow door.

In the Electronics Lab are three tables.  Each table is equipped with oscilloscopes and function generators.  Oscilloscopes are used to see how the voltages vary in time between two points in a circuit.  Function generators, on the other hand, are used to generate voltages varying in a particular way in time defined by amplitude, frequency, and phase.  The wall across the tables contains power supplies, resistors, diodes, and transistors.  The opposite wall is a large white board.  Between the walls is a sink and a window that opens to a view of the  JGSOM Student Enterprise Center (JSEC) where students run food stalls.

Ateneo Physics News interviewed Numeriano Melaya, the Physics Lab Technician who supervises the Physics Laboratories in SEC C, regarding the new Electronics Laboratory.

1.  How did the Electronics Laboratory came about?

In 2001, the General Physics Laboratory transferred from Faura Hall to the Science Education Complex . There are two rooms in the General Physics Laboratories: the preparation room and the maintenance shop for the laboratory. In 2004, it was decided that the preparation should be located between the two labs, leaving the end room vacant. This room became the extension of the workshop.  Because the workshop is small, we requested for one machine shop: a small building outside the General Physics Laboratory.  The machine shop was built in 2005 during the time of Fr. Daniel McNamara, SJ. After two years, the JSEC was built. In 2010, the work shop was demolished and transferred to Faura Hall. The preparation room became vacant and became a stock room of old equipment.  Later, it became the research room of Fr. David Skelskey. When all equipment was transferred to the new machine shop in Faura, such as the lathe and milling machines, we requested that the other room in SEC C 108 be renovated.  This was done in 2011 and Fr. Skelskey transferred there.  Then we requested  that the storage room be made into an  into an electronics lab. Our request was approved.

2.  Were there any difficulties when the Electronics Lab was proposed?

When we applied for the renovation, we submitted quotations from the contractors, but the budget was not included in the 2011 budget.  This 2012, we were asked to coordinate with the Office of Adminstrative Services for the remodeling.  I thought our request was disapproved.  Coincidentally. Fr. Jett Villarin, SJ came during the recruitment for his AJSS (Ateneo Junior Summer Seminar). He asked why is there a storage room. I said it was proposed to be made into an Electronics Lab.  Two days later, the Director of Purchasing informed me that he wants to meet with me, Mr. Ivan Culaba, and Architect Canlas.  We met and we agreed to push through with the Electronics Lab before the start of classes on June 2012. After three weeks, the renovation was finished.  Now the students are using it.

3.  What is the significance of the Electronics Lab?

Before, the teachers of the ECCE Department handles the teaching of the electronics course, because we have no facility for the Electronics Lab.  Now, the physics department offers this course for its students.  We still need ten function generators and oscilloscopes.  Yesterday, we asked for quotations for digital oscilloscopes–not necessarily high end. The Lab is small, just good for 12 students with a maximum of 15.  But the lab is now similar to that of the ECCE department.  We will still update the lab equipment every year.
