For many years (since the 1990's), the SETI institute (the Search for Extra-Terrestrial Intelligence) has had far more data than they could deal with alone. To get some help with this, they decided to send out all the data to the rest of the world. In the last 15 years, Cal State Berkeley has been making this data and many other MASSIVE projects available to everyone who wants it, via BOINC.
What is BOINC?
BOINC stands for Berkeley Open Infrastructure for Network Computing. It's the inevitable result of what Scientists and Researchers developed after they realized that they could get the world's computers to help them decode the universe. BOINC is effectively what Crypto mining was before Crypto; using many computers across a massive network to solve problems that one computer would take too long to do.
Why Do This?
The likelihood of making money from this project is much lower than making money from mining Crypto. There are some projects that do offer rewards for completion, but the prizes are small, and you do not get incremental awards for progress. So, you are doing this because you like the idea of helping the world solve problems, that one small group could not do alone. Participating in BOINC is almost purely altruistic.
Tricks to get more out of the App
Alter your options: Go to Preferences, Check the "Show advanced preferences and controls", scroll down. Set "Max battery temperature" to less than 35 C. I used 32.7 C (90 F). This will keep the phone from ever getting too hot.
Perk has been around for several years and although it's certainly not in it's Hey Day any longer, it still a candidate for passive income if you know how to play it right.
What is Perk?
Perk is a company that pays you to perform tasks. There are several tasks
(1) Sign Up
(2) Watch Videos
(3) Take Surveys
(4) Play Games
(5) Get Paid
The creators of Perk know that people like money, even if it's a tiny amount of money. A little money here and there over time becomes a lot of money. But you probably already know, that they're making for more from the tasks that they give you, than they pay you. So...
Why Do This?
Perk exists in the "grey" area of typical business practices. If you do the things listed above, they will in fact pay you. But the amount that is paid minuscule as is the skill required to do such. However the grey area allows that people with a little knowledge to do something that most people are not willing to do.
Most people who encounter the Perk Suite, do some survey and watch some videos, but realize all to quickly that they may never reach the minimum payout and that leaves all that profit for Perk. But to those who persevere will find the ...
Tricks to get more out of the App

You may have heard of this on the internet; how you can run this on your phone and make some extra money. It's definitely a real thing. Using your spare data, HoneyGain will pay you for any bandwidth that you're not using via your phone.
You're already going that way, why not get paid to do it? Roadie is an economical service that is similar to the original intent of Lyft / Uber. The idea is that you're already heading in that direction, why not go a little further out of your way to take another item with you. Current delivery services pay their drivers a wage to deliver, but those services are already created for that purpose.
You'd never guess that you can make money just for driving your car. Not for driving and picking stuff or people up, like for Uber / Lyft / Postmates, etc... but for literally, just driving. That's the concept for Smiles.
How does it work?
Smiles is an insurance analysis company that has created an app to track what people do while driving. Smartphones are more than just pocket computers, they have all sorts of sensors that can detect things like GPS location, speed, acceleration, deceleration, even ambient temperature. These are things that Smiles needs from drivers. They need to collect as much data as possible to help in their insurance analysis of how people drive.
They need the data and they have figured out that most people are willing to give it for a pittance of payment. But they need you to actually move further than a few hundred yards.
Payment is $0.03 per mile up to 110 miles per day ($3.30 per day)
Without digging too deeply into the Internets you will definitely find some shady stuff. SwagBucks sounds like a great deal on the surface. Do Stuff, Get Paid, right? There's no two ways about it, how much time are you willing to spend doing stuff, to get cash and gift cards?
Have you ever wondered if there was an app that would pay you to do simple tasks? Well, there is, in fact there are many, but unlike so many of the apps out there, this one is made in Germany and therefore has a very different take on simple tasks.
