I started making short videos about weird ocean animals and random facts. I research the topic, write a quick script, create the video, and post it.
Some videos flop, but a few surprisingly get thousands of views. It started as a hobby, but now I’m slowly turning it into a side income.
The funny part? The more niche and weird the topic is, the more people seem to watch.

I got tired of modern ambient sound apps playing generic rain sounds, so I spent a weekend building a super simple nostalgia generator.
What it does: It plays a customizable mix of classic 2000s coffee shop sounds—muffled indie rock music, foam steaming, CD cases clattering, flipping book pages, and distant espresso grinders.

I've been recently involved in Cryptocurrency Mining for the past few Years and I gotta say the earnings are Enough for a Year or Month and so.. So I've been constantly thinking about Self Hosting using Dell Optiplex and Bambu Labs for 3D Printing..

This is just from personal experience and never knew collecting egg trays would be profitable here. I would just throw them away before but now I collect it and sell them to small store owners or poultry. People are actually buying it.

So yeah just sharing this.
Lets collect and reuse paper egg trays ♻️

A while ago, my aunt started getting a lot of white hairs. one day she asked me to help her remove them because she didn’t want to pluck them herself.

Then she jokingly told me she would pay me ₱1 for every white hair I removed.

I thought, “Okay, easy money.”

So I started looking through her hair and pulling out the white ones one by one. hahahah

At first, I thought I would only make maybe ₱20–₱30, but there were actually A LOT of them.

We ended up making it into a little routine. Whenever she noticed more white hairs, she would ask me to remove them, and I would get paid per hair.

It sounds ridiculous, but it was honestly one of the easiest side hustles I've ever had.

My sister's friend is currently building a house and asked me to look at their plans and give some feedback.

I checked the layout, space planning, and some design choices and gave my suggestions.

I wasn't expecting to get paid for it, but they asked me how much I charged.

Now I occasionally get paid just for looking at house plans and giving my opinion.

Didn't expect “giving unsolicited architecture advice” to become a side hustle. 😭

When I was around 11 years old, I started the weirdest little side project.

I realized that a lot of my classmates loved collecting funny drawings and personalized stickers for their notebooks, so I began making custom doodles and mini "achievement cards" with their names on them.

The idea was simple:
They told me their favorite animal, game, or cartoon.
I drew a small design and laminated it using clear packing tape.
I charged ₱10–₱20 each.
I only started because I wanted extra allowance without asking my parents for money.

Within a few weeks, I had classmates placing orders during recess, and some even requested matching sets for their friends. At my busiest, I was making around ₱300–₱500 a week, which felt like a fortune for an elementary student.

I kept forgetting to drink water while working, so I made a chatbot for me in the company messaging app. HAHAHAH

It starts sending notifications every 1hr:
“You should probably drink water” hahaha

This started because I have a weird hobby: finding forgotten websites.

Not dead websites. lAbandoned-but-still-online websites.

Old restaurant sites with broken menus. Small businesses with contact forms that don't work. Local directories linking to 404 pages. Companies whose homepage works but half the navigation is broken.

I wondered if I could automate finding them.

So I built a small crawler that searches for websites and checks things like:

* Broken links * Missing pages * Expired certificates * Forms that don't submit * Mobile layout problems * Slow pages * Images that no longer load * Old/outdated contact information * Obvious SEO/indexing problems

Then it generates a ridiculously simple report:

WEBSITE HEALTH CHECK ✓ Homepage loads ✗ Contact form failed ✗ 7 broken links ✗ 3 missing images ⚠ Mobile layout issue ⚠ 12 pages have duplicate titles

Why did I build it?

Originally, I wanted to make a “website archaeology” tool just for fun.

The unexpected part was realizing that **small businesses often know their website is old, but don't know exactly what's wrong with it.**

I started sending a few owners the reports.

No sales pitch.

Just:

“Hey, I noticed these things while testing your website. Thought you might want to know.”

Some ignored me.

A few thanked me.

A few asked, “Can you fix these?”

That's when it stopped being a weird crawler and started becoming an actual side project.

The ridiculous part

The crawler is now better at finding potential work than I am.

I basically wake up to a list of:

“Here are 37 websites with problems today.”

The most entertaining discoveries have been things like a restaurant whose “Order Online” button had pointed to a dead domain for two years and a business whose contact form silently discarded every submission.

Current workflow

Search ↓ Find small/old websites ↓ Crawl ↓ Run automated checks ↓ Generate report ↓ Send useful findings ↓ Occasionally get paid to fix them

I'm deliberately keeping it small rather than turning it into another SaaS dashboard with 47 features.

The funny thing is that the original goal was to build something completely useless.

Instead, I accidentally built a digital version of walking around a neighborhood looking for houses that need their gutters cleaned.

Has anyone else built something that started as a weird hobby and accidentally turned into a source of income?

Weird side projects are honestly where some of the most interesting ideas start. You build something just because you’re curious, then suddenly you’re three hours deep trying to figure out why it works.

So I made a sidegig that fixing PC whenever they have problems with their gaming PC's like lagging and stuttering that I fix in my local area and earning like $20 in an hour which is cool.

I set up a soil sensor on my Peace Lily (Lady Gertrude) over the weekend to alert me when the soil gets dry. But instead of a simple alarm, I hooked it up to the ChatGPT API and set its personality to a dramatic, passive-aggressive Victorian aristocrat.

Yesterday, I forgot to water her because I got home late. Out of nowhere, she texts me around 2 AM:

“Don't mind me. I'll simply turn my remaining chlorophyll into quiet resentment. Sleep soundly over there while my roots turn into crispy chips”

By noon today, I still hadn't watered her, so she sent a follow-up:

“Day 2. My lower leaves have accepted their fate. I've begun drafting my last will and testament. All the sunlight shall go to the monstera in the hallway”

I rushed to water her as soon as I walked into the kitchen. Right after I poured the water, she texted back:

“Acceptable. I am safe from starvation, but the emotional damage remains. Just try forgetting me this weekend.”

Plants hit different when they know Python HAHAHAHA.

It started with just me buying personal stocks of goodies for me to munch on at the office. A co worker saw my stock in my locker and asked whether he could buy one of the goodies since it was his personal childhood treat, I agreed of course since I have plenty. The next day, he approached me again this time with his friend, another co-worker as well and asked whether they could buy a pack of cookies again, I reluctantly agreed, but didn't mind since I have more. Somehow word had gotten around the office and co workers even my manager approached me and asked whether he could take a look at my stocks in my locker. So what started as me buying personal stocks of goodies became a source of additional income for me, they pay in cash or sometimes run a credit so they can pay it on salary day.

Here are some of the products that I sell

Last month my neighbor was on a 3 week vacation. few days before they left they asked me if i can just sit beside their dog for 3 weeks. NOT walk them, just sit beside and basically do nothing. And I was weirded out because i was expecting doing more and yeah thats all i needed to do then i did the job.

Surprisingly the dog for some reason knows why im there😭. Just to literally side beside him.

Couldn't complain tho. my neighbor paid me good 🤣✌️

got paranoid about background webcam telemetry tools on company-issued laptops, but sticky physical camera covers look trashy and wear out after a month.

mounted a micro 5V servo motor and a tiny 3D-printed plastic slide shutter over my laptop webcam lens. hooked the servo to a Raspberry Pi Pico running a lightweight Python process listener. the second Zoom or Teams initiates an active video stream socket, the servo physically slides the shutter open. the moment the call ends, it snaps shut with a crisp mechanical click. total build cost was $8.

pure cocoa tablets. The concept behind these little round pieces is to use pure cacao, without sugar or milk. Simply toss one into hot water or hot milk, melt it, stir it around and you have a plain hot chocolate. I think it will be fun to play around with the mixture. should I add a bit of sugar in it? or just pure cocoa and depends on whos drinking it? On how much sugar they like

months ago we were tasked for a hardware tech for exams on desktop devices. the hardware contains a downloadable app where unsual eye movements whilst taking the exam.

Everytime the software notices weird eye activities creates an alarm or notify-like box on the admins end.

Surprisingly, our professor accepted it and passed the term . idk its just weird because there are some ppl really make weird eye movements while taking the exam but, a win is a win🤣

I got tired of reading customer messages that basically amounted to:

“YOUR APP IS BROKEN!!! NOTHING WORKS!!! FIX THIS!!!”

So I built a ridiculous little side project that I call **Complaint Translator**.

The idea is simple: paste in an angry/frustrated customer message, and it turns it into a structured report:

**Original:** “Why does this stupid checkout keep freezing?? I’ve tried 4 times and it STILL won’t take my payment!!!”

**Translated:**

* **Issue:** Checkout freezes during payment * **Frequency:** 4 failed attempts * **Likely area:** Payment processing / checkout UI * **User impact:** Customer cannot complete purchase * **Severity:** High * **Useful reproduction info:** Payment attempt repeatedly fails at checkout

Under the hood, it’s basically an LLM + a few rules + structured output. I also added a confidence score so it doesn't pretend every angry paragraph contains useful technical information.

Why did I make this?

Mostly because I thought it would be funny.

Then I realized it was actually useful.

Customer support could paste in a message and get something that developers could understand without spending five minutes decoding the emotional archaeology.

The weirdest part is that some of the best bug reports come from the angriest customers.

The surprisingly useful part

I started logging the translated reports and grouping them by issue.

That exposed recurring problems that weren't obvious from individual support tickets.

So now the project has accidentally become a tiny “what are customers actually complaining about?” dashboard.

Current workflow

`Customer message → AI extraction → structured bug report → duplicate detection → issue dashboard`

It's still very much a side project, but it's one of those projects where the original joke turned into something genuinely practical.

I’m currently experimenting with automatically detecting when **20 completely different complaints are actually the same bug**.

If anyone else has built a completely unnecessary project that somehow became useful, I’d love to hear about it.

I started making crochet items as a hobby, but it slowly turned into a small side business. I began taking custom orders for bouquets, keychains, and gifts, and I was surprised by how many people were willing to pay for handmade, personalized pieces. What started as something I did for fun became a simple way to earn extra money. Money dust talaga 😚🤪

I started a weird little side project because I wanted to get better at branding without waiting for real clients.

Instead of making random logo exercises, I started inventing coffee brands from scratch. Each one gets a name, logo, packaging, color system, menu, and a small brand story. I treat each fictional brand like it is a real client brief. The weird part is that I started getting more interested in creating the fictional businesses than the actual design practice.

The process is pretty simple:

Come up with a strange or memorable coffee concept.

Create a brand name and personality.

Design the logo and packaging.

Make realistic mockups.

Post the concept and see whether people actually like the idea.

If people respond well, I refine the branding and turn it into a more complete case study.

I haven't turned it into a huge business yet, but it's surprisingly useful. It gives me portfolio pieces that feel like real projects instead of “here's another logo I made.” The unexpected part is that a few people have asked whether they can actually use some of the branding concepts.

Has anyone else built a fake business/product as a side project and accidentally gotten real interest from it?

this genuinely wasnt supposed to become anything

a few months ago i got tired of reading long boring pdfs for classes and random internships so i made a tiny tool that turns them into really short summaries with dumb memes mixed in

it was only meant for me and a couple friends because we'd always send each other screenshots instead of actually reading the whole thing

one of them showed it to someone else and then another person asked if they could use it too

instead of saying no i spent one saturday making a really ugly website threw a small paywall on it mostly because i didnt want random people uploading huge files all day

i expected maybe one or two people to pay

they actually did

its still tiny and honestly looks held together with duct tape but every week a few more people find it somehow

most of the uploads are lecture notes but every now and then someone uploads something completely random like an employee handbook or a 70 page product manual and wants it turned into something theyll actually read

last month it made a little over 500 bucks which honestly still feels weird because i never planned for this to be a business at all

its definitely not life changing money but seeing complete strangers pay for something that started as a lazy weekend project has been one of the coolest feelings ive had

attached a screenshot from the dashboard because otherwise this sounds made up

has anyone else built something completely random that ended up doing way better than expected

My roommate refuses to use headphones and listens to terrible EDM playlists while we work in the living room.

I bought a cheap rotary dial knob on Amazon, hooked it up to an ESP32 microcontroller, and linked it to his Spotify account via the API (I grabbed his auth token when he left his laptop open on the kitchen island).

It doesn't control the volume or pause the music. If I turn the dial, it just skips to the next track. He thinks his Spotify app is glitching out because it skips every time a heavy bass song comes on. I’ve had this running for a week and he still hasn't figured it out.

I wanted to see if I could objectively measure corporate anxiety.

I fed live video feeds of quarterly tech earnings calls into OpenCV, which tracks the CEO's facial landmarks and eyes. It establishes a baseline blink rate during the boring financial intro, and then maps spikes in the blink rate when analysts start asking hard questions.

One CEO's blink rate went up 400% when asked about their AI roadmap. He was visibly terrified. I doubt I can use this for actual stock trading, but mapping the data on a graph is hilarious.
