Student engineer · Project showcase

Engineers aren't born. They're built, one small project at a time.

I'm Sanjith, a high school student in Introduction to Engineering Design. This site shows what I've built, how I built it (including what broke), and how you can start your own engineering path this weekend.

Why build

Projects teach what lectures can't.

Classes give you the theory. Projects show you what the theory is for, and that's when it sticks.

01

Learn by doing

You remember the circuit you debugged for two hours far longer than the one on a worksheet.

02

Build the engineering mindset

Define the problem, test an idea, fail, adjust, repeat. That loop is the job.

03

Practice the real workflow

Requirements, design, build, test, document. Every project is a small version of how real teams work.

04

Stand out

A portfolio of things you made shows ability, not just grades. It gives you stories for applications and interviews.

05

Grow the soft skills

Planning your time, documenting your work, explaining it clearly, and not quitting when it fails.

06

Find out what you love

Mechanical, electrical, software, aerospace. Small projects are the cheapest way to try each one.

What I do in a projectWhat engineers do at work
Sketch ideas and list partsRequirements and design planning
Learn Fusion 360 through several failed attemptsDebugging and mastering professional tools
Rebalance a car's weight until it runs straightIterative testing and optimization
Write up what I built and learnedTechnical documentation and reports
Brainstorm with a team and give feedbackDesign reviews and team communication
The process

Every project follows the same six steps.

The finished build is the smallest part of the story. Click through to see how I work.

Lessons learned

Mistakes I made so you don't have to.

After every project I wrote down what I'd do differently. These are the lessons that stuck.

Let go of ideas that almost work

My fling machine's second idea went about ten times better than the first. I held onto the first one too long.

✎

Start drawing sooner

I put off my coffee-pot isosketch. Once I started, drawing made things easier than planning everything in my head.

Try it yourself before asking

On my ISO Shapes project I asked friends about dimensioning too fast. Working through it alone is where I'd learn most.

⚙

Learn your tools early

In Fusion 360 I wasted time hunting for tools. Once I learned where they were, I stopped needing help.

Every idea deserves a hearing

On the Mars Rover Challenge I learned that teamwork is a skill, and the best idea can come from anyone.

Persistence beats failure

My car failed, then failed again. We kept at it and built the fastest one in the class.

Projects

Things I've built.

From my Introduction to Engineering Design class and my own projects. Every one has a problem, a build, a failure and a lesson.

Cardboard race car prototype held together with duct tape, with wheels, wiring and a battery holder

Cardboard Motor Car

Built a car from cardboard and tape using required parts within strict length limits. Learned to distribute weight so it ran steadily. After setbacks, my partner and I built the fastest car in the class.

Fastest in the Class

The payoff for not giving up. My partner and I took medals, and our fling machine also launched farthest in class, over 100 inches.

Radar Sensor Project

An ultrasonic sensor on a servo, wired to a microcontroller and joystick on a breadboard, held up with painter's tape. Prototype first, polish later.

Fling Machine

Using only the given items, we built a machine to fling a cotton ball as far and as accurately as possible within a time limit. Our second idea worked about ten times better than our first.

CAD in Fusion 360

Puzzle Cube, ISO Shapes and Automata Box. I recreated dimensioned objects, built an interlocking puzzle cube, then joined parts, rounded edges and animated the finished box.

My path

One class led to the next.

This is the route I'm taking through my school's engineering program. Each course builds on the one before, and each has its own portfolio page.

Start yours

It's simpler than you think.

You don't need a lab or a big budget. You need a free Saturday and the willingness to be bad at it for an hour.

Pick something small

One problem, one weekend. Smaller than you think.

Set a time limit

A deadline keeps you finishing instead of perfecting.

Document as you go

Photos and notes. Your failures are your best content.

Share it

Show a friend, teacher or this site. Sharing makes you better.
