Day 3: Intro to Stepper Motors: Why should I even bother spending my time understanding stepper motors? What’s the purpose of writing code, and what does a “good reflection” even mean when I’m drowning in questions? I’ve thrown every spare moment of my life into chasing new things—new ideas, new tools, new possibilities. But I never stop to look back. The further I stretch my gaze, the smaller I become, as if I’m collapsing under the sheer weight of everything I’m supposed to learn. It’s ...

Goal: Build a 3D scanner. Explore Arduino, Stepper Motors, Sensors, Math, and CAD How Should I read a report? How should I implement math to tune my data What should I do with a 3D scanner? What limitations do I have? Day 1: Analog distance sensing What is Analog vs Digital? Analog Sensing: Produces continuous data that varies smoothly over (T)ime. NO DATA DELAY Directly reflects the data: Output voltage/current changes proportionally with the measured quantity. However, since ...

Who’s Fire When there’s a fire there’s a claim Not the witness Not the wise But the glory But the name All must be one All must be none The clown on the Chair Heard the Fire The Clown said That must be mine The Clown’s Dog Barked and waved Pissed a few ink On history’s name When there’s a fire There must be a victim And there must be death For which the clown can save Not save the death, but sold the tears For the dog’s piss named history When the clown cry The dog cry The victim cry The Clown s ...

Robotic Arm What does a Robotic Arm Look Like? Gears End Effectors Anything Metal Not really: Since Robotic Arm is invented by Humans, we get to decide its function and look. Biomimicry: Before this project, I’ve started to think about biomimicry—how nature’s mechanisms can inspire robotic systems. In biological organisms, movement is rarely rigid or purely mechanical. Muscles, tendons, and joints interact fluidly to adapt to the environment with precision and efficiency. Biomimetic principl ...

Ronaldo’s Quote "I said this one year and a half ago and I will continue to say it: the problem is not the coaches. "I always give this example, it is like the aquarium. If you have the fish inside and he is sick, and you take him out and fix the problem. If you put him in the aquarium they will be sick again. “The problem of Manchester United is not only the coach. It is much more than that.” The Second Red Horror Last season (2024–25), we almost got relegated. Fifteenth. Out of ...

PNP The first unit of the Technology Seminar class asked us to collaborate and create a nameplate for the admissions team. Though I don’t have everything recorded, I still want to share some of my approaches and progress. Background Before this project, I already had some experience in CAD — I made my own PC case. It was my first big CAD project and took about a month… and it was painful. Here’s a little gallery walk: Looks cool, right? But it only looks cool. I didn’t leave enough margin f ...

My Pressure I always laugh when I saw this meme that our forefathers fought in the great war to save humanity and us from evil dictators, yet after their death they came to realize that the Gen Z now have depressions or pressures. It is a joke to them and to me. I thought, only those who experienced great trauma or great misfortune have the right to claim such honor. Others, are losers. A loser that is a failure in society. Nobody cares. Unfortunately, thoughts can be a crime. And I was sentence ...

CMOS “What we didn’t realize was that it would reduce the cost of electronic functions by a factor of a million to one” - Jack Kilby Complementary Metal-Oxide-Semiconductors What is CMOS? CMOS stands for Complementary Metal–Oxide–Semiconductor. MOSFET Structure and Terminals The MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is the building block of CMOS. It has four key regions: Source: where carriers (electrons) enter the channel. Drain : where carriers exit. Gate : a metal elect ...

Phones Can’t Trap Us A gun doesn’t become notorious because it is made out of metal. A gun is just a commodity that is man-made. Nicolas Cage is not the War of the lords if there are no wars. Simply, selling weapons create such conditions for war. Drugs did no became a problem until laws permit it. Should we then ban democracy if it is such system that allows drugs to be legal? So recently when I was traveling around the globe. I often see banners,PSA, or healthcare ads warning us to not g ...

Short Story I was customizing air filter panels. Why? Because I’m being irrational with my money. Just kidding. I was messaging a Chinese factory that specialized in producing paneled air filters. Here’s how the conversation went: 1234567891011Me: How much for one panel, 155mm × 255mm × 10mm?Manufacturer: Sixty for one, or a hundred for four.Me: How about fifty for just one? I only need one.Manufacturer: Wait, let me check with my supervisor...Manufacturer: Our starting price is sixty, but we ca ...
