Hello Mr. Castillo,
I came across your website. I don't remember you doing websites before. I guess you learned it just recently. I moved to Las Vegas with my cousin who was also a graduate of Sam High School.
Glad to know you are doing websites now. Thanks for you teaching us electricity by way of the house project.
I learned to install lights and switches in the house saving us money. LOL.👍🏻❤️😂

HI, Mr. Castillo,
I remember the light transmitter you demonstrated in our class in physics. You tried to encourage us to take the challenge of assembling it for the science week project. Too bad none of us dared to accept the challenge. I thought it was too difficult for me. But it was a very interesting demonstration of how light could be used to transmit music by, to use your own words 'making music ride in the light'. I forgot the term you used for that. LOL. 😂
Anyway, congratulations on you website. I am impressed.👍🏻

Our electronics club in school helped me prepare for the electronics and communications engineering that I pursued. Thank so much, Mr. Castillo. You are an awesome teacher.

I remember the light music transmitter project that you showed us in our physics class.
I wished we had that for our mandatory project in addition to the houselighting one from which i learned how install bulbs and switches in the house. A good one Mr. Castillo.

like history repeating itself...i still remember assembling a superheterodyne radio when i joined the electronics club.. in 1974 i guess..you were the instructor...i think i still have it somewhere...it encourage me to take up electrical engineering.and..i guess the rest is history
