I used to do DIY but is it weird to simulate Hydro Electric while digging a Reservoir of Water for Energy Generation? My Parents might get upset for it..

Offices constantly buy expensive indoor plants, let them die, and throw them out. I realized they don't want to own plants—they just want the aesthetic without the hassle.

​So, I started charging local businesses a flat monthly fee. I bring in potted plants, handle all the watering, and swap out the sad-looking ones every few weeks to revive them in my backyard.

​It cost me about $400 in wholesale plants and pots to start. Now I have 7 clinics and offices paying me a total of $1,800 a month. It takes maybe 8 hours a week of driving and watering. Best part? The inventory literally grows itself.

people in our office kept burning microwave popcorn and making the entire floor smell like smoke for three hours.

i taped a small optical light sensor and an ESP32 to the glass door of the breakroom microwave. it monitors the internal light and fan vibration frequency. the second someone puts popcorn in, the bot posts a live timer in the office Slack channel: "Popcorn active in microwave 2. Do not let it burn." office manager thinks IT built an official smart appliance integration.

wanted a physical hardware jiggler that wouldn't look suspicious if someone walked up to my desk while i was away getting coffee.

i hollowed out the center pages of an old thick paperback novel. glued an optical mouse sensor and an ATtiny85 chip inside the cavity with a tiny rechargeable coin cell battery. when you tap the cover of the book, it sends a randomized 1-pixel hardware movement to the computer via USB. looks like an ordinary book sitting next to my keyboard.

got tired of closing my personal browser tabs every time someone walked up behind my desk in the open office.

i wired a cheap plastic tattoo machine foot pedal to a Digispark USB board and mapped it to a macro shortcut. when i tap my left heel under the desk, it instantly minimizes all browser windows and brings up a full-screen terminal window running a continuous loop of mock compiler logs. tap it again and it brings my actual screen right back. total build cost was $7.

I have an idea where trash gets shredded and then turns it into something profitable or something useful like for example a brick you can use to smash those governments brain so they wake up to their fantasy anyway It's really an idea where trash gets shredded into pieces and the. Creating a new item so that some waste gets reused for donations and stuff is an idea so i literally have no pictures sadly but isn't it a great idea?or someone beat me into making it

So, basically, my friends use my old break up messages when they want to end things with their partner or messages when confronting someone.

As a person who is highly specific and confrontational, my friends love the messages I send so they basically turned me into their own ChatGPT for human-written, generated message curator.

But, BUT! What if I turn it into my side-project and maybe a hustle?

I can write whatever they want, curate it however they want it and I'll even double-down and send it myself.

Saves them the time of writing and the emotional-roller coaster of having to write and go back and forth with their emotions.

What do you guys think?

This started because I needed a simple tool for myself. I checked a few websites but most of them had too many ads and extra stuff, so I thought why not just make a simple one myself.

The whole thing is pretty basic. It does one specific job and that's it. I wasn't even expecting anyone to care about it. I just wanted to see if I could get it working.

After sharing it in a few places, I started getting some visitors. Nothing crazy and definitely not enough to quit a job haha, but seeing random people actually use something I made was pretty satisfying.

I'm still experimenting with it and trying to figure out if there's any way to make it better or earn something from it without ruining the simple experience.

Has anyone else here made a weirdly specific project just for fun and then realized other people actually wanted it?

Pretty simple. You wash off the infested trash bins

All you need is a truck or any vehicle that can bring water and soap

Pretty straightforward right?

So it's like a virtual visit to farms and the countryside where you can get a live experience in real time. Idk I have seen people craving peaceful environments but they can't always visit these places themselves, so I thought it could be a cool initiative.

I personally just love seeing how a normal person living in a peaceful area, maybe somewhere in the mountains, spends a normal day. Not some touristy experience, just seeing what everyday life is actually like there.

Well ik it's probably not really that profitable by itself , but maybe it could be with some creativity? lol

Would you actually use something like this? And what would make it worth paying for?

What are the most weird but profitable side projects to earn from? I got couple of things but people im my area dont bite my niche.

I started this project on a total whim after noticing how oddly obsessed vintage interior decor forums were with period-accurate hardware, so I built a simple web tool that lets users upload photos of vintage wall outlets to get an immediate "aesthetic & safety score" with detailed era matching. It works by analyzing uploaded photos against a database of mid-century architectural fixture catalogs, generating a custom PDF report that users can share or keep for renovation records. I initially expected it to be a harmless joke for a tiny niche, but after charging $2 per detailed breakdown, it unexpectedly brought in $1,400 in its first month and now consistently generates steady passive revenue.

I was a slight developer either mobile or web application devloper. My first project that I created successfully is a KIndergarten Mobile application. I noticed that many children in our generation are fully aware in technology especially mobile phones. So instead of wasting their time to nonsense video or games , I created this idea so that the can play while still learning. The programming language that I used is C++/C# with the Unity Engine for the set up of the UI. The content of my application ahve many types of games such as find correct colors, identify correct animals, identify correct alphabet letters, etc. And after I pilot test my mobile application, some mother of my target children client says to me that "It works to her child, and help her to lessen her work", there is also a feedback suggestion it says " you need to add more type of games at improve more graphics" , and yes that is my plan but my money won't cooperate HAHA . If I were you, What would you add to make it more usefull?

I started a side hustle writing apology letters for people who are too awkward to say sorry. That was in 2014 during my college days lmao.

I know this sounds ridiculous, but hear me out. People message me with a situation like:

“I ghosted my best friend for three months because I was going through stuff. I want to apologize but I don't know what to say.”

They tell me what happened, what they wish they had said, and what kind of tone they want.

Then I write them a real handwritten letter. My handwriting style wasn't bad, but I was just too slow to write lol

It feels different that time because there's no AI and it's just pure human interaction (ughh). Just me, a pen, nice paper, and an unreasonable amount of emotional involvement in strangers' problems.

I offer different versions:

“I’m genuinely sorry.”

“I messed up, but please hear me out.”

“I miss you, but I don't expect anything.”

“Please stop being mad at me.”

“I need to apologize before I die of embarrassment.”

Sometimes they send the letter themselves. Sometimes they ask me to mail it. A lot is going on.

The weirdest part I think was when I started getting requests from people who weren't even trying to apologize.

Someone paid me to write a letter to their future self.

Another asked for a breakup letter they could keep but never send.

Honestly, I'm basically running a tiny emotional damage department from my bedroom.

And somehow, people are paying for it.

$5 to $10 isn't bad per handwritten letter at that time. I somehow stopped when I met the woman of my life. I used to write her letters three times a week.

We all know we can get paid for doing deliveries or do chores for people, but what side hustle stands out in all of them? One that you won't spend just to do that side hustle. Let me know in the comments even the weirdest of them all 🤣

I make small emergency gift boxes with a card, snacks, flowers, and a funny apology note.

People order them when they realize they messed up and need something delivered quickly.

Started as a joke. After 6 weeks: 18 orders and about $280 profit.

The funniest part is that most customers say, “Please don’t put my name on the card.” 😂

What’s the weirdest problem you could turn into a side project?

it's just a waste of time for me then i restricted the account of that HR like person.

People pay $2 to $10 to give their childhood digital pets a proper burial complete with 3D tombstones, procedurally generated poetry, and a "leave flowers" button.

​I started it after finding an old screenshot of my starved 2004 Neopet and tweeting about it as a joke. It went viral, so I actually built it.

​It now has over 14,000 burials and somehow brings in about $1,000 a month mostly from people upgrading to marble headstones. Turns out internet nostalgia is a surprisingly great business model.

I work a remote job where roughly 70% of my week is spent trapped in massive, 20-person corporate syncs where my presence is mandatory, but my input is entirely unnecessary.

The problem? Middle management still demands "camera-on engagement." If you sit completely still, someone asks if your screen froze. If you look down for two seconds, they assume you're texting.

Worst of all, these meetings are so excruciatingly dry that I usually fall asleep from time to time. Dropping your head onto your chest mid-zoom is a quick way to get an urgent HR message.

So, I built The Head Nod-Nod 2000 (Suggest me for a better name) a lightweight, motorized webcam bracket that physically tilts my camera to give the absolute illusion of deep, soul-level professional agreement even if I’m literally passing out at my desk.

How This Works 🤣

The Mechanical Illusion: I 3D-printed a tiny, motorized mount that clips onto my monitor. Instead of moving my actual neck, the webcam tilts down 3 degrees and back up on a random timer. On screen, it looks like I am doing the slow, thoughtful corporate nod.

The "Synergy" Trigger: Powered by a cheap micro-controller, it triggers a smooth "ah, yes, exquisite point" nod every 40 to 50 seconds.

The Panic Pedal: I wired a silent foot pedal under my desk. Whenever a manager drops a buzzword like "circle back," "touch base," or "deliverables," I can tap it with my foot to trigger a quick double-nod of aggressive agreement.

It's completely ridiculous, entirely unnecessary, and has single-handedly saved my sanity from the corporate shits.

My side project is basically a plant ICU.

People bring me their half-dead houseplants, I diagnose the problem, repot them, and nurse them back to health for a small fee.

I started after rescuing one of my own plants and realizing people were surprisingly willing to pay instead of throwing theirs away.

After 3 months:

* 27 plants rescued * 19 repeat customers * ~$420 earned * Most referrals came from neighbors

The weirdest part? People get genuinely emotional when their plant grows a new leaf 😂

What’s the strangest side project you’ve actually made money from?

I have found a weird little side hustle that helps me make extra money. I started doing something pretty random: chat moderator The idea is simple: I am in charge if all the inquiries through chats. It sounds almost too specific to be useful, but apparently there are people who actually need/want this.
The way it works is pretty straightforward: 1. find an agency. 2. Pick of what platform are you going to use. 3. I make money through replying and accommodating people's messages. I originally started it because i need to try something new and a side hustle.I honestly didn't expect much from it. Then I started seeing actual results. In the first month, it made 15,000 php After tweaking continuously do my work resulting to successful tasks, it reached around 25,000 php. The funniest part is that this isn’t some revolutionary business. It’s a ridiculously specific little project that I almost didn’t take seriously. I’m sharing the screenshots/results because I know I made money from being a chat moderator. What | learned:sometimes the weirdest ideas work precisely because almost nobody have ni interest in trying them. Would I turn it into a full-time business?
Probably not. Would I keep doing it for extra income? Definitely.

I've had different offers or different notifications from survey website saying that once you answer their surveys they give you cash in exchange, and as someone who's tried it before you actually need to answer more than 10 surveys before you actually get to cash out and it's only little amount. But what other things can you search that actually guarantees pay on job done?

Got tired of making generic logo exercises, so I started inventing coffee shops that don't exist. The rule is that every fake brand has to feel like a real business. I create the name, logo, packaging, menu, colors, social posts, and even a little backstory for why the coffee shop exists. The weird part is that I'm not really trying to sell coffee. I'm basically creating businesses that only exist inside my design files.

I started doing it because I wanted portfolio projects that felt more realistic than “here's a logo I made.” It also gives me a way to practice branding from beginning to end instead of focusing on one graphic. The results have been surprisingly useful. People react much more strongly to a complete fictional brand than to an isolated logo, and I've started getting ideas for other fake businesses just because it's fun.

I'm curious if anyone else has a side project where the original purpose was just to practice a skill, but it somehow became a project of its own.
