The Website of David Tsai
Why orange? Redemption. We march on. For L.

My name is David Tsai, and I am a high school student from New Jersey. I code applications, design websites, and write music all while balancing my schedule with homework and extracurricular activities such as my school’s award-winning Marching Band and Wind Ensemble as well as our F.I.R.S.T. Robotics Competition team.

If you want a website ranging from a small résumé-style portfolio to a fully-blown realtime website with a custom content management system, contact me for your very own custom-built website today. My extensive experience in web design started with the building of my first humble HTML document back when I was in second grade. Over the years, I’ve created websites for businesses including law firms and design studios as well as revising my own website to become the huge project that it is today. I know all about page optimization for fast loading speeds, user-friendliness, stylish designs, and browser compatibility (although my own website ignores this last one). If you want a fast website that works in all five major browsers, loads quickly, and is appealing to the user, drop me a line, and we’ll work out a deal.

Below is an activity feed that combines my posts from YouTube and Facebook. It used to include my Twitter feed, but Twitter has since blocked this server from accessing its API probably because someone abused the API from another website on this server.

Light-Dependent Resistor (LDR) on DC Power Supply

Now, I use a light-dependent resistor (LDR) as the load on a DC power supply.

Light-Dependent Resistor (LDR) Demo

I have my multimeter measuring the resistance of a light-dependent resistor (LDR) that changes resistance when light hits it. When no light hits the LDR, the resistance is greater than 60,000 Ohms. When light from my desk lamp hits the LDR, the resistance drops to about 3,000 Ohms.
