Electrical Engineering Experience:

My Personal Circuit Designs, Custom Applications, Projects, Research, Reports, …and more!

 

 

Aug 2013 –  ±15V Power Supply for my 8x8 RGBHV Matrix Switcher  (my Home A/V System)

This is a very standard circuit I designed, tested, assembled, and installed in a single weekend to restore operation to the 8x8 composite video matrix switcher I integrated into my centralized apartment A/V system.  This unit handles all HD Video switching to the (4) LCD/LED flat panel displays around my apartment.

 

    

 

Aug 2013 –  ±15V Power Supply for my 8x8 Composite Video Matrix Switcher  (my Home A/V system)

This is a very standard circuit I designed, tested, assembled, and installed in a single weekend to refurbish an 8x8 composite video matrix switcher I would later integrate into my centralized apartment A/V system.  This unit now handles video switching for all DVD players/recorders, security camera feeds, low-res cable tuner feeds (for SD recording), and play station in my apartment.

 

      

 

Dec 2012 –  Externally-Controllable +24V Power Supply for my BIAMP AudiaFLEX  (my Home A/V System)

Well aware of my strong background in circuit design / hardware design, my boss at Hoppmann Audio Visual gave me a top-of-the-line BIAMP AudiaFLEX digital audio processor that wasn’t working.  I was not surprised when I opened the chassis to find a failed universal power supply. 

 

I custom-fitted a 24V@3A external power supply inside the AudiaFLEX, along with this custom control circuit, enabling third-party power on/off switching via 3.5mm input port on rear panel.

•  Power on/off is controllable via CMOS/TTL digital logic, or contact closure (input mode is selectable via DIP switch). 

•  When nothing is plugged into the control port, the system operates in “ALWAYS ON” mode and sends power through to the motherboard.

•  When a control cable is plugged into the 3.5mm jack, the circuit enters “EXTERNAL CONTROL” mode wherein the system default is POWER OFF, unless a high logic level or contact closure is sensed on the control input pins.

•  A single bi-color LED [on rear panel] indicates power status: GREEN=ON; RED=OFF.

Oct 2011 –   Logic-Controlled Relay

A simple transistor switching/relay circuit I designed, tested, & assembled [in 4 hours of personal time] to satisfy a contract deliverable in a touch-panel-controlled audio system I programmed for my company.  It allows the digital logic output from a BSS Audio processor to trigger on/off the powered speakers hanging from the auditorium ceilings.

Mar 2009 –  Interviewed by a First-Year Engineering Student  (for credit in his Freshman Seminar class)

I didn’t know this underclassman but I expect one of the EE professors I had worked with gave him my contact info knowing I would be an indulgent interviewee.  I’m not sure if he was supposed to interview me in person, but due to my very busy schedule, I had him send me the questions and I responded in writing.  I selfishly over-indulged; going into deep description of what motivated me as a child and adult to pursue electrical engineering.  All-in-all, this piece of writing provides a unique perspective into my passion as an engineer.

 

Jan 2009 –   Letter of Support for Professor Mark Wharton  (by PSU AES)

Professor Ken Jenkins, the  Department Head of Penn State Electrical Engineering , personally invited me to write a letter of support for Professor Mark Wharton, an exceptional Electrical Engineer and circuit-design mentor who received nomination for an award recognizing his excellence as an instructor.  It was truly my pleasure to have had this opportunity to express my appreciation for his significant contribution to my development as an engineer & circuit designer.

Mar 2008 –  Power Amplifier Output Stage: BJT vs. FET (Research)

Written for ENGL 202 (Technical Writing), my comprehensive research on the subject quickly overwhelmed the strict 3-page limit of the writing assignment.  To stay within the page limit, I could only include ≈20% of the topics I researched.  As an appendix, pages 5 and 6 are my hand-written outlines for BJT research points and FET research points, respectively.

 

Feb 2008 –   2-Way Loudspeaker PVC Towers  (by PSU AES)

Jan 2007 –   Voltage Controlled Low-Pass Filter

This was a small piece of an application I intended to design that would have united all of my current automotive circuits (Bass-Activated LEDs & Engine-Controlled Neon Lights) under a single control structure with even more functions and a better design.  I halted my work on this project in September 2007 when I joined Penn State’s Audio Engineering Society (PSU AES) and launched the two-year Amplifier Design Project.

 

  

 

May 2006 –  High-Power Outdoor Tent Light

Features a fully-adjustable high-intensity tricolor LED array and 6V halogen bulb.  The light fixture secures tightly to the inside roof of the tent.  In LED-mode, the brightness of each LED array (red, green, and blue) is fully-adjustable so that the user may create virtually any color desired.  In Bulb-mode, the halogen incandescent bulb can be adjusted from “very bright” to “dim”.  The entire Tent Light application is controlled by a small, low-power wired remote.  Requires 12Vdc @ 1A max.

 

    

  

       

 

May 2006 –  +9V 1.5A DC Power Supply

Designed to power a SONY stereo boombox from an external 11V to 40V unregulated DC source.

This control panel houses the main power & function switching for my engine-controlled neon power circuit.  It also contains circuitry that integrates the bass-activated function of my LED circuits, plus additional features.

 

         

 

Sept 2005 – Automotive Neon Lights:  Engine-Controlled Power Circuit

Converts the 100mV square-wave of my engine's optical rotary sensor to a high-power DC supply voltage that increases proportionally with the rate of engine rotation.  The neon tubes are powered by the DC supply so that when my engine is idle, the neons are off, but as my engine RPM increases, the neons turn on & become increasingly bright.

 

   

   

 

Dec 2004 –   Designing Systems for EMC (Research)

This is a topic I researched for my own enjoyment while I was designing circuits for SPIRIT 3, a corporate/university-sponsored project to develop an experiments payload for an atmospheric rocket.  NOTE: This is an incomplete paper without citations, but I hope it will serve as a useful reference to some.

Topics include: Methods of EMI Transmission (impedance coupling, electric & magnetic field coupling, and far field coupling);  Areas That Affect EMC (Distance between source & victim, effective loop area, conductor quality, power distribution quality, and shielding).

The  improved version  of my  High School graduation project : better circuits, more functions, more colors, and a lot more LEDs.

•  Four types of high-intensity LEDs: Red, Green, Blue, & Amber.

•  Two sensitivity adjustment knobs:

o  COARSE Sensitivity Adjustment: varies the DC reference voltage of the comparator.

o  FINE Sensitivity Adjustment: varies the gain of the second amplifier stage that feeds into the peak detector circuit.

•  A switch lets me disable the LEDs facing the rear seats, and another switch lets me disable the LEDs facing my subwoofer box & amp in the trunk.

 

    

      

    

                                                                                                      

                                                                                                       

 

Feb 2003 –   Bass-Activated LED Circuit:  version 1

My  High School Graduation Project  for State College Area High School.  Red and blue high-intensity LEDs were mounted throughout my vehicle and controlled by this circuit.  The LEDs are triggered by a comparator circuit that turns them on when the audio bass (<100Hz) amplitude exceeds a reference voltage.  I adjust the sensitivity of this circuit by adjusting the comparator reference voltage via potentiometer mounted in the side control panel of my vehicle.  The LED brightness is also adjustable from the control panel, and there is a switch to select either blue LEDs only, red LEDs only, or both the blue and the red LEDs.

My EE Childhood: I was born to be an Electrical Engineer!

*written June 2006

August_1994__sHere I am (left), a few months before my 9th birthday (spring 1994), in the process of removing a motorized propeller circuit from a TYCO hovercraft and preparing to mount it to one of my extravagant LEGO Technic creations.

 

I was in my EE infancy back then; an adventurous young boy just beginning to realize the AWESOME power of electronic technology.  I had already spent years disassembling equipment and marveling at circuit boards, but I was finally developing a qualitative understanding of current and voltage, while taking full advantage of my family’s 1989 World Book encyclopedia volumes.

 

I was fascinated by electromagnetic phenomena.  I experimented with numerous home-wound electromagnets, and even constructed a single-pole DC pulse motor for extra credit in 4th grade (fall 1994) — *special thanks to my elementary school teacher, Mrs. Karen Boston*.  I would later construct the same DC pulse motor during a Physics lab activity as a high school Senior (Spring 2003).

  

Driven by an intense passion for electronic invention, I continued experimenting by creating simple security alarms, small motorized machines, and a variety of electronic ignition systems for homemade fireworks.  I also developed a passion for audio, and as an enthusiastic 10-year-old I began operating the professional sound equipment (mixers, power amps, etc.) during Sunday services at my local church, The State College Free Methodist Church. 

 

While serving as my church’s Sound Man from ages 10 to 12, I continued with my own research and electronic design/customization.  My interests expanded to include subwoofer & mid-range speaker box design, and more notably into the area of wireless electronics with a botched attempt at making a wireless remote ignition system for my ESTES model rockets. 

 

With the advent of my inquiries into wireless technology, it became clear that my elaborate engineering ideas had begun to exceed my limited abilities as a novice.  I wanted desperately to keep learning but simply didn’t know how.  My parents lacked the necessary scientific background to offer me any meaningful direction, so most of my more advanced ideas unfortunately never materialized.  Nonetheless, it seems I was gifted with an all-consuming passion for electronic invention; a passion that would then lay dormant until a great high school teacher, Mr. Douglas Ripka, gave me the knowledge & direction I needed to rekindle my fiery zeal and start learning and experimenting again on my own.

  

After completing my first Electronics course at age 15, I’d obtained enough background knowledge to begin independently studying EE textbooks.  With the help of Mr. Ripka in the years that followed, I gained impressive skill & extensive experience in all aspects of electronic circuit design, and have continued to this day on my lifelong journey of electrical engineering.
