Hey! Raymond here. I’m a product design engineer!

Pardon the rather empty portfolio. I’m trying to port my stuff over from Canva to a standalone domain… and it isn’t going exactly as planned. I’ll get there, though. One day.

(noun) A torrential flow of water refers to a rapid and forceful movement of water, often characterized by heavy rainfall that overwhelms the capacity of drainage systems.

TorrentLabs is my personal portfolio focused on generating as many ideas/designs as possible, acting as a playground sketchbook of sorts for my brain after work.

The skillsets.

What’s with all of the portfolio robots?

One of my hobbies that I like to do whenever I’m not engaged in some sort of engineering project is graphic design and 3D digital art. As a result, I’m often saturated in an environment where I would always end up doing some sort of CAD -- be it working on photoreactors or making a fighter jet that has practically no reason to exist. Nevertheless, a side quirk from this was that I got pretty good (and fast) at visualizing designs, a trait that got me further interested in the world of engineering.

I grew up in a robotics heavy environment, but I did not have the available resources to really financially support the building of multiple FTC competition robots. As a result, I spent most of my free time stuck to CAD, where I can truly express my engineering skills without financial constraints.

I love my 3D printers!

From receiving my first 3D FDM machine back in my freshman year of high school to managing a 12-printer Prusa/Bambu farm at my current job, 3D printing has always been a cornerstone of my engineering journey and my go-to tool for rapid prototyping.

Fun fact: I am Yummy Future’s resident printer farm parent :3

Machines I’ve worked on:

Prusa i3 Mk3s
Artillery Sidewinder X1
Bambu X1 Carbon
Bambu A1
Bambu P1s
Markforged Oynx One
Creality Ender 3 Pro/S
Creality Ender 5
Prusa SL1
Voron 2.4
Ultimaker S3

Materials I’ve worked with:

PLA
Nylon
CF Composite Nylon
PETG
RCF/PLA
TPU (all durometers)
ABS
PC

I am horrifyingly addicted to CAD.

also minecraft :/

In some way, it’s some sort of freedom for my brain — I wanted to see how creative my imagination can get when I didn’t have to worry about the constraints of the real world — yet . As a result, many of my creations here didn't stem from a pre-existing need. They were about exploration and the joy of creation.

In 2022, I got my first professional CAD certification as a PTC Onshape Associate.

Current Project(s).

Longboard LED Signaling System

Living and working in a college campus means that there will be pedestrians, cars, scooters and inline skate/longboarders everywhere. As a longboarder, I understand how much of a menace we are in society when it comes to right-of-way intersections and aggressive lane-changes down campustown.

Unfortunately, the only way for us to signal to other people that we’re changing directions or turning is to wave frantically in hopes that our arms can catch the attention of oncoming traffic.

This easy-install signaling device that I am working on will seamlessly attach to longboard trucks and automatically notify others of the rider’s turns, stops, and emergencies — hopefully giving drivers a helping hand in rider awareness.

Condor STOVL sUAS

Working on drones at work made me realize throwing things into the air are really cool.

Unfortunately, it’s pretty hard to get something to stay in the air for long. As a result, I’m challenging myself to design a catapult-launched flying-wing STOVL that will be able to loiter for long periods of time and be able to vertically land itself.

This is a personal project to educate myself on aerospace fundamentals and step into the hobby of RC flying.
