Ask HN: What is your money-making side project outside programming?

1134 points| napolux | 6 years ago

Always wondered this. Sometimes I feel the need to do something else outside my field, and possibly get some money out of it.

Breville coffee grinders are impossible to get internal parts for. I designed a 3D printed upgrade for the main wear-part in their BCG800XL and BCG600SIL Grinders.

The storefront is through ShapeWays[1] and I use iFixit[2],[3] to drive the traffic. It passively makes enough to cover my own coffee needs forever. I spend about 20 minutes per month fielding questions. This all happened because my grinder failed and I could not get parts.

My wife bought your part and it worked perfectly. She was really happy when she found it. Thanks for making this part available.

I use a super cheap hand grinder I bought off amazon (the stainless steel one that there are 100 different variations of on amazon). There is a plastic part that breaks after about 6 months of usage. Someone modeled and uploaded a replacement piece to Thingiverse. The grinder is cheap enough that it is disposable, but since it is so easy to print a replacement piece with my $179 3D printer, I haven’t needed to throw it away. I hope that at some point 3D printing becomes more accessible and affordable, and with more materials, that more and more products are repaired instead of replaced.

I recently ordered a part for my daughters dresser drawer - the Kenlin Rite-TrackII, and paid $12 for four including shipping. 6 to 7 years ago I paid $68 for a single part. To my surprise when I opened my recent plastic mailer envelope, I discovered it was a 3D printed piece. Any idea how one can 3d scan a part for exact copy?

Thanks! My 800XL grinder failed a few months ago, now I'll be taking it apart and buying your part if necessary.

I buy cars, repair them and recondition them to my level of satisfaction, and send them back out the door, typically targeting 55-65 year olds. I focus mostly on entry level luxury crossovers around 7 to 10 years old, though starting to also do hybrids since there’s more profit in it since everyone is seemingly allergic to batteries and pack replacement/rebuilds.

Parts are cheap, I listen to music or a podcast, I do all the “PITA” repairs (replacing wheel bearings, ball joints, tie rods, full brake service) that are really just labor in terms of professional repair cost, perform additional rust prevention, and for sale it goes when I feel a new grandma or grandpa would never give a hesitation to load it up with all their grandkids. They also see a very thorough interior cleaning, and a full exterior detail (including paint correction when required).

It has bought every very nice tool I could ever want, most are 20-30 hours of labor including acquisition, and I’m at the point where I have repeat customers (the put a 2nd alongside the first) and have direct referrals. Now the profit mostly goes towards putting a 2nd interesting car in the garage, and some towards moving up the ladder to try to earn more per vehicle.

Selling cars isn’t bad when you don’t have employees to pay, and it lets you sell really high quality stuff. I keep thinking of how much I couldn’t justify doing, and how much my product standards would suffer if I had to pay help.

Can you make YouTube videos about it? I watch Chris Fix all the time, not for educational purpose (I don't own a car), but because they are so freaking satisfying to watch. Seeing things go from 'meh' to 'wow.'
[+] ryandrake|6 years ago|reply
As an amateur shade tree mechanic myself I have so many questions! Feel free to ignore if you feel you'd be giving away your secret sauce.

1. Where do you find buyers? I'd be concerned about inventory either piling up or taking too long to sell at a price that even breaks even when you are spending time/money on fixing.

2. Do you feel your value-add is more on the sales side as a broker or is it in the repairs? I know people who just flip cars and do extremely minimal "freshing up" and are also profitable/successful.

3. How do you keep up with the increasingly locked down and opaque ECUs and other systems? More and more diagnostics require factory wizardry these days.

4. You implied that you do paint and body work. Where/how did you learn and become proficient? Most auto repairs are pretty much "follow the steps" work anyone can learn from YouTube, but body work is artistry.

5. Do you worry about liability? I'm OK fixing my own car since if I screw up it's my ass on the line. I'd be less confident in sending the car off to grandma, even if I knew what I was doing.

There's definitely a benefit to working on the same model/series more than once. Three fourths of my amateur mechanic hours are split between asking "now why won't this darn thing come loose?" and "Oh! So I didnt't need to take all this apart to get to this piece!"

Launched in 2016 for free. Started making money in 2018 with $3,000+ MMR. Referral only (side) business. I work full-time as an engineer/principal in growth.

I conduct a form of ethnography, embedding myself in the lives of consumers the way Margaret Mead did among Samoans. I interviews my subjects and the people around them, itemizing the contents of their home (photographing and videotaping), and accompany them as they progress through their day. Then I sift the resulting information for weeks, even months, looking for connections and telltale behaviors.

The service is used mostly by founders for small businesses and startups. I takes questions about sales figures and product lines and reconfigures them into questions about worlds, the context in which people unthinkingly live their everyday lives. The idea is that examining the beliefs and unconscious biases that people have will eventually yield profitable insights for these businesses.

So far, I've done market entry for a few Chinese companies into Japanese market, helped indie game design company launch a successful game, a boutique lingerie shop launch a new summer line, street musicians, and a few cafes and bars.

I do this on the side with hopes to go full time into it soon.

I established DamnInteresting.com in 2005, a place where myself and handful of others produce original long-form non-fiction in article and podcast form. Despite plenty of traffic, it didn't reach the break-even point for several years, because I despise advertisements and I refused to add them to my site. I funded the project in other ways, such as donations, publishing a book, licensing content, etc.

Nowadays it still only earns a little every month, but that's mostly owing to a rise in expenses (e.g., I pay the contributors more). But profit is secondary for me, my primary motive is to have an excuse to research and write this stuff, and for intelligent people to consume it.

Kudos and thank you for resisting advertising and figuring out an alternative business model. It would be awesome if there was a whole alternative Internet like this, where ads (and selling user info) was forbidden.
[+] sink|6 years ago|reply
Thank you! I found your site long ago and I’ve enjoyed every article. I often wondered what your plan for it was and would be. This puts a little closure on it. I feel the same way about advertising and wonder what alternate business models could happily maintain such a place while keeping it mostly free and open.

Wow, I always thought damninteresting.com was wildly profitable. Not sure why - I have been reader since the early days and always found the content to compelling and "sharable" - I'd have imagined that it would be extremely profitable.

I suppose without ads there isn't a lot of high-monetization opportunities.

Thanks a lot for creating and maintaining the site. If you ever need any help with the design and front-end development of your site, let me know - I'd love to volunteer some time to the site that I love so much.

I make and sell staff paper notebooks for musicians: https://www.themusiciansnotebook.com/

I'm an avid saxophone player and am taking evening classes in theory, so I made this to solve a problem that I myself had. Nothing else like it on the market!

Every part of this notebook is automatically generated with a bunch of python scripts: the cover design, the interior, the line placement, the margins. The program basically spits out a PDF which I can then send to print shops (which is the hardest part of the whole thing!)

The product is good, people like it, and the hardest part for me right now is sales - trying to get stores to carry it, or get traffic to the site to drive sales! If you know anyone who might be interested...

edit: Okay I've opportunistically created a coupon code THANKSHN for 10% off.

Two things, both of which I stumbled into accidentally -

I make lots of jellies once the berries in the garden are ripe; I bought a house in a rural area a few years ago and it came with loads of berries. Might as well put them to use.

It is all done manually (in part because it is meant to be a diversion from my engineering job) - red- and blackcurrant and gooseberries mostly. Last year the harvest was some 1200 4oz glasses of jelly - some 1150 more than my family consumes. Sells by word of mouth.

Also, as my mother is quite into weaving tapestry and it was hard to find the exact hues she wanted for her yarns, I started dyeing for her, using traditional colouring. Turned out there was a (veee-eeery small!) market for that kind of thing, and I now make small batches for some 30-35 weavers. Again, fully manual as the idea is to do something completely different from my full-time job.

I've written a couple of books that sell on Amazon and Apple iBooks - it takes zero minutes per month work for me, but brings a nice little side income. I won't get rich, but it's nice to have the money come in for doing nothing after I hit the "publish" button. Even the printed books cost nothing.

I'm about to hit publish on a photo coffee-table book from my three years around Africa, and I'll write an Africa guide book and The Road Chose Me Vol 2 in the next 12-18 months.

* The Road Chose Me Volume 1: Two years and 40,000 miles from Alaksa to Argentina (https://amzn.to/2vfCYvn)

Stories and lessons from two years driving my Jeep Wrangler down the Pan-American Highway

* Work Less to Live Your Dreams: A practical guide to saving money and living your dreams (https://amzn.to/2OD6UtA)

An eBook about how exactly I can afford to take years off work to do what I want and live my dreams.

* West Africa Myths, Misconceptions and Misnomers (https://amzn.to/2veyQMt)

After driving the length of the continent, I collected a bunch of information that is extremely helpful to anyone else thinking of doing similar. The vast majority of the Western Worlds "knowledge" of West Africa is so out of date it's useless. My book is from info I learned during my drip from mid 2016 to late 2017, so it's relevant

I taught myself circuit board design and found a niche market that I designed a few products for that sold like gangbusters with zero marketing for a few years until the market cooled off and low cost knock offs started entering the market.

I also found that you could use the same CAD program that I learned to design PCB's to draw outlines to cut out on the laser CNC machine at the local maker space. I ended up finding a niche on ebay building open air computer cases. Because of the economics of shipping large items from overseas and the low cost of the materials I was using I was able to under cut the imports on price by like 60% and still make a nice amount of money on a $/ hour basis.

In hind sight the best way to find these kinds of opportunities is not to be looking for them. You really just need to get a really deep understanding of a hobby or industry or market that interests you in some way and once you have that then these sorts of things kind of pop out of the woodwork.

About 10 years ago and ten years into my career, I had been working and stayed at the same job way too long and both my salary and career stagnated.

I had two part time money making side projects. I was a part time fitness instructor and had some rental real estate.

Teaching fitness classes was fun, I made a lot of friends, and it gave me a release valve from working at a computer all day. Real estate was a headache.

Around 2008 -2011, a few things happened. The real estate market crashed and I did a few “strategic defaults”, I realized I could make a lot more by getting better at software engineering and job hopping, and I got married and gained a wife and two (step) children.

I gave up all of my side projects, concentrated on my career, started building a network of recruiters, former coworkers, and former managers and doubled my income over the next 8 years (not bragging, I still make about the average of principal engineer/architect/team lead in my area).

Even looking over the next two to five years, I should be able to increase my income by 50% (working for local companies) to well over 100% (if I can get into Amazon) as some type of cloud consultant, “digital transformation consultant”, or “Architect”. The only thing stopping me now is the travel requirements. I want to wait until my youngest completes high school.

But, that means I can’t juggle my job, family commitments, working out, filling in some technical gaps and a side job/business.

So no side business.

I raise bees and sell the honey. Good for a few thousand a year and the money makes up for the stings. I have a couple of dozen chickens and sell the eggs, but this makes very little money since eggs are so cheap in the super market. It pays for the feed and that's it. I wrote an Amazon book on how to play harmonica in the style of Sonny Boy Williamson II that sells steady and makes me beer money. I sell a couple of my Science Fiction short story collections on Amazon. "Error Message Eyes" and "Frogs in Aspic", but after a good first year they sell only a couple of copies a month. I sell four or five Science Fiction stories a year, but only occasionally do I get pro rates. It's nice to see your name in print, though.

Not really a productive venture, but it was profitable. I used a 3% cashback credit card on a financial company's money sending service with no fees, and sent my sister $3,500 every two days. She'd then eventually pay me back through bank ACH (also free). Then I'd pay off my credit card every week so my credit balance remained low. Made about $1,500 a month for a year, before they stopped giving cashback for transfers.

I did a coffee kiosk once. It went well, but required a large amount of energy and focus.

We did a little twist on the business model. Starbucks sells nice places to sit down. We sold drugs. The model, from logo design to promotions, was designed to create a habit loop where people would get their morning coffee from us.

It was so profitable that I seriously considered making it my full time career, expanding cafes all over the country. The only thing that changed my mind was 1) the startup boom 2) dealing with minimum wage workers is extremely depressing. The tech industry has its abundance, whereas with food and drinks, it was clear that income was limited and had to be managed carefully.

In addition to regular index fund investing I trade options sometimes. Been doing it for about 6 months now and I'm up about 90%. I am a lot more conservative than most options gamblers but it's still pretty risky. I put all my gains into high earnings stocks (currently buying STX and LYB) and at this point since I've almost doubled my principal, I could lose basically all my money currently allocated to options and have only lost 10% from my initial investment. I do it somewhat as a way to earn money but mostly for the experience, since I think it helps me learn a lot about how equities are priced and how the market reacts to news and macro events.

Rather than continually making bets just for the sake of making bets I only make trades when I think a stock overreacted to bearish news (meaning it's likely to rebound to its old price given that the business' fundamentals are unaffected), was oversold due to underperformance of other stocks traded alongside it, or is greatly overvalued due to some irrational hype (Lyft and most canadian weed stocks). And I sell quickly if the option loses a lot of its value or if the option greatly appreciates to lock in profits and limit losses.

For the past few years I've been buying, renovating, and selling small-ish houses. My dad was a contractor growing up so I picked up most of the necessary skills helping him out during middle and high school. I mostly work on weekends and holidays which makes it a bit slow going, but I've made a reasonable amount of money. Even if the money was worse I would still probably do it, I really enjoy both the physical aspects of the work and seeing a house go from a beat up old husk to a shiny new place! I have to contract out some of the work (electrical mostly) because I'm not a certified electrician, but otherwise it is a one man show.

I do electronics repair for cars. For many older and rare cars it's usually no longer possible (or desired) to replace broken electronic components such as the engine or transmission controller. So owners contact me to have the part repaired instead of replacing it.

The repairs are usually not that challenging for me, and it won't make me rich, but it's a great way for me to clear my head from challenges with my tech startup. It also gives me access to some very rare and expensive cars. Obviously you need to test drive the car if you just fixed the ECU ;-)

* Act as a standby for dish pits at the local restaurants - filling in only when someone doesn't show since I don't want to take what could be a lifeline job for someone AND having a standby like me means they can keep their job instead of just being a no-show

* Write articles for other people - usually on topics I really don't have a lot of knowledge or feeling about to start.

* Mow lawns - I'm allergic to grass. Builds character.

* Labor - the harder the better. Beats the gym and there is no better way to turn a Budweiser into a $100 beer than sweating your tail off digging a ditch.

* Help startups bootstrap or otherwise avoid "the man" while they find their dream.

* Sell chicken eggs when the hens push more than I can French toast.

* Make films, music, stories, pamphlets...often these cost more than they make, but I refuse to call them losses. Slightly passive income stream.

* Consult - since I was 11 in '81 I've been paid for helping people with their broken technology. I'm not exactly on the edge of all tech like I was, but I still serve a purpose.

* This is an odd one, but I have found it at least as profitable as a few side projects over the years. Be lucky. Actually look for money on the ground ($143 last year), win prizes, expect financial benefits from transactions, assume your (educated) choices will make money.

* Sell plant starts - a little late for this year, but it's one of those things you can save seeds from your regular groceries / food prep at home and early Spring...ba-da-bing ba-da-bang...kind of almost free plants!

* Investment clubs - getting a small community of a tech nerd, business geek, social butterfly, and either an accountant type or law dog, plus whatever else you happen to be friendly with, you can end up with a very smart engine for investing. Invest in either public stock, local businesses, people with ideas, or projects of your team's own creation.

Have fun, and profit!

I'm a lawyer who doesn't do much (any) marketing. But when someone gets referred and calls or sends an email asking for help with setting up an LLC, helping wind-down or sell their business, or even something small like reviewing an NDA, I can jump in.

I'm solo, so I don't have any overhead and I can charge far less than anyone else. This is also entirely a side gig, so volume is so low that I can be responsive, helpful and more like a thought partner who is also helping out on legal.

Probably going to be downvoted, but I do adult webcam stuff, mostly with private already established regular clients. My net profit can be as high as $1200 per week, $800 on the low side, for a few hours of “work”. I generally use it as a fall-back income when I’m in-between tech jobs but I do it if I’m employed or not to keep my paying client list fresh for when I need it. I could make a lot more, I have a “cam friend” who makes $5k/week regular but he does it full time and markets himself and such. I put the minimal amount of time & effort into it.

Three things for me:

1) I own a small rental property in Florida that is fairly low maintenance and pays for the mortgage + a small amount each month on average. This is a long-term ROI play since after taxes, maintenance, repairs, and everything else it ends up being close to a wash until the principal to interest ratio on the mortgage payments improves after 5+ years. I only say this because everyone and their brother in my age group seems to want to retire on rental properties, but in reality it's really not that great.

2) Basic ETF investing in a combination of value-oriented and dividend-oriented ETFs. This is, in my opinion, the only way to get truly passive income with literally zero ongoing effort.

3) I design and 3D print props and cosplay pieces on a referral basis for commission. In reality it's a horrible way to make money since quality 3D modelling for 3D printing is time consuming to the point of the hourly effective rate being lower than minimum wage, but I enjoy it, so it's kind of a semi-paid hobby.

Makerpad.co - I teach people how to build projects without code. I’m collaborating with companies now to help provide educational content on how to use the tools for a non-technical project or business. Last 4 weeks revenue is around 30k (from memberships and companies paying to be listed and create the content which isn’t released yet). It’s pretty much all profit too as I do it solo with little overhead.

There’s a huge interest growing around building without coding and any technical people are also jumping in too.
