Biggest question that comes to my mind - if you can make this profit so consistently, why not triple your rig? Or even x10, or x50?
That’s the plan! But I’m already at 80% maxed out on a 30A 240V breaker. Sure I could add more breakers, but I really don’t want to turn my basement into an industrial mining zone (not to mention the HOA might have a thing or two to say). I’ve already used some soundproofing (Rockwool) in the room that all the mining equipment is in, the noise is real! Also I need more airflow, I’m exhausting extra heat out a small b…

#213Open Source Hardware! Specifically a USB Oscilloscope: https://espotek.com/labrador Sell maybe $1k/mo of these through the website and another $3k through Amazon at a margin of around 50%. The biggest things that I see a lot of people get wrong in the hardware business is the importance of manufacturing and logistics. It doesn't matter that you're constantly producing new and improved revisions of your board if you'r…

#215My little hardware book, Computer Engineering for Babies launched on Kickstarter a few months ago and blew my mind by raising almost $250k. It’s a simple book with buttons and LEDs to demonstrate different logic gates. I just shipped out the first batch of books a week ago and now waiting for the next batch of books. It’s gotten pretty demanding pretty quickly but I’m really excited about it. I’m hoping I can soon em…
Curious if you were aware of the Baby University books from Chris Ferrie, and if so, worried about potential lawsuits?

That’s a $30,000 rig at least. So 300 days of mining before you just break even. I’m sure that in 300 days it will only be able to mine a fraction of what it does now due to increasing difficulty. I’m not seeing how this truly works out.

#217I made that cool frontend for FTP server with an interesting twist as I've abstracted:
1. the backend storage: meaning it connects to a wide range of existing storage like FTP, SFTP, S3, Dropbox, ...
2. the authentication layer: meaning you can use your own identity provider to put your S3 buckets behind your corporate SSO
3. the authorization layer to create business rules
At its core, the software is a framework to develop file manager like web applications by implementing a simple interface (https://github.com/mickael-kerjean/filestash/blob/f7a4e52703...). This does enable all sort of interesting use case. For example, the mysql implementation shows database name as first level folder, tables as second level folders and each row in a table is shown as a file within the table folder which a user can edit directly through the generated form built from the schema information. That way people who are used to the Dropbox interface can edit the database directly, create shared links, search through stuff without having to know about sql
Most of the money comes from companies who needed various degree of customisation and support or didn't want to host on premise.

#219I own 4 shares in the S&P 500. I developed trading strategies to sell my shares and buy them back at key points using Fibonacci retracements. Best business ever. And if I leave it it still makes money. I’m nowhere near $500/month but learning to trade simply has taken me years and I’m very proud of my smol accomplishment.

You could say I’m “wasting energy” for “monopoly money”, but that monopoly money gets converted to fiat dollars, which I use to pay taxes and feed my family passively while I’m at my actual job, or sleeping. If instead of mining I were to work a labour intensive job as a side-gig, moonlighting, driving there, how much more or less energy would that “waste” on gas? At least I’m recycling my exhaust heat into heat for…
I'm curious if you've ever worked out a ballpark "hourly pay" for your crypto mining operations. By that, I mean: (hours spent on research, hardware acquisition, setup, and maintenance) / (net profit, after accounting for hardware depreciation and obsolescence)
