Online? If yes, which platform do you use?

If you're going long term, the platform doesn't matter at all. With short-term trading quants have a huge advantage (I went through an interview at a hedge fund, I know how smart they are, but their downside is that they have to have high sharp ratio to attract investment). I'm always looking at 5 year+ investments only

What's their typical threshold for Sharpe ratio?

I licensed my house as a winery, and run a hard cider company with my girlfriend. We sell to some stores in our area, and do our local Farmer's Market during the summer.

It's been very satisfying making and selling a physical product.

The profitability part isn't quite there yet. But we're working on that.

I am a corporate drone and not a programmer, but anyways; I sell computer chips on the Craigslist of my home country. Mostly Intel CPUs, genuine and not engineering samples. Wherever eBay can't reach due to import tolls, there is a market. Profits are at around 30% margin. It feels fun and does not feel like work. It has helped me save up to some nice vacations. Going to Japan in the summer. This activity is somewhat…

I am reading all these comments with joy. I picked up options trading as a side gig, it works sometimes, it does not work some time. I am satisfied with it, but reading this thread made me wonder if I should not try something "real". If there are other similar threads, please do link to them. This Sunday will then be productive :)

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…

When I look up MMR I get "measles, mumps, and rubella." I assume that isn't what you're referring to.

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 basica…

I think most users went digital, like iPad or kindle. There're apps where you can type notes or search and buy existing sheets. Of course paper is better for kids or beginners, so you could push your product in that niche.

BTW those digital sheets are pricey, so I wrote some scripts to generate PDF for my kindle, the output looked quite neat. I used LaTeX, Lilypond and perl to comb out unsupported stave notation from songs I ripped from public sources.

Attempting to make money making side projects and instead just expensing servers and subcontractors and getting the tax refund from everything my employer withheld by April

You aren’t really making money here. Just getting the money you made back.

Clever. Do you have the intention to make more replacement parts for other products?

I would like to if time permits. There is a huge untapped market here. The difficulty is in locating the parts that are both unavailable and 3D printable. I keep it in the back of my head as I repair other items. So much expensive stuff ends up in a landfill over a tiny part. I could see someday having a github project for replacement parts, each one iterating and getting better an better -- far beyond the original.

I recently had to replace the side wheel motor assembly on a Roomba. The motor and housing were fine, but the gears inside had worn out. I think they were just made out of ABS, so if they were printed in Nylon they would be a lot longer wearing. Roomba do make their robots (at least the 620 I have) repairable and a replacement of the whole assembly was only £20 so I'm not sure if the margin is there, but it is a bit wasteful when the only issue was the gears.

I've also considered creating some upgrades to the stock parts, but it's on my "some day I'll get around to it" list.

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 co…

Is it good grade plastic? Do you print it yourself?

Want to team up on an a milk gallon jug attachment to pour cleanly?

Firefighter/medic and wildland fire contractor. I pull in about 15% of my base tech salary doing a few hours of work a week and one wildland fire deployment per year. It's a hobby that turned into a side profession and feels great to help people.

The increased risk of cancer is a big downside.
