This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.
This is slightly different than eBay Arbitrage. Find a distributor that will sell to you at their discounted prices. List these items online. Buy and ship to your heart's content. Basically, you become a reseller of computers and other hardware. Another thought here is to sell computer parts. Can you find a part that seems to be in demand? If you can supply the demand, you may just have yourself a part-time business.
Etsy. Are you crafty? This is one of those websites where, once again, it helps if you have a real skill. If you're artistic and are the type of person who can make custom jewelry or refrigerator magnets with the best of them, Etsy is the place to sell it. For the rest of us, we must find another website to go to, so we can earn money to buy things from the crafty people at Etsy.
Find work. When you first start out, you may have to accept work writing about a topic you don’t find all that interesting. You must keep an open mind and be willing to accept work that may not be in your desired field. However, as you continue to write, you not only learn about more topics, but you also build your reputation. With time, you can be choosier about assignments you want to accept.[19]
These are sites that post short tasks that pay per piece. These tasks may involve anything and everything, including data entry, writing, tagging, surveys, and more. Most don't pay much per piece, but the key to earning substantial extra money with them is getting fast at the tasks you do accept. Below are a few sites to consider trying that pay for short tasks:

If you have an eye for design and some experience of creating websites, then you could offer your services as a freelance web designer. You will need to create your own stylish website, and have a few other projects that you can show potential clients to demonstrate your skills. You will also need to initially spend time emailing businesses to promote your services and find work.
I understand the need to build a profile, but again, after several minutes of answering repetitive questions, I am either told I don’t qualify, or I’m sent an email which contains a broken link, or…you get the idea.  I would gladly spend 30 – 45 minutes answering a survey, submit, and earn the amount of $ it said it would pay.  But, these last four days have been a royal waste of time. 
Amazon Mechanical Turk is a service that lets you make money online through doing paid microtasks. Each task is something simple that requires human interaction like rating search results, checking for the right spelling on search terms, categorizing the tone of an article, or even basic translating. You can do these tasks from anywhere you want and make money online from the world’s largest e-retailer.
You can earn above average rates of return because peer-to-peer lending eliminates the bank function. That means that you participate in nearly the entire interest rate being paid by the borrower, rather than the less than 1% that you will typically earn on certificates of deposit. And you can reduce your risk by investing in slices of hundreds of different loans.
Right now on Upwork, they are looking for more writers. Set up a profile and start offering up your fast writing skills. You can make decent money with freelance writing and some people are able to make it a full-time business.  Check out this interview I did with a freelance writer who has had a lot of success and shares how to start a freelance business.

VIPKID provides an international learning experience to children in China between the ages 4-12. Headquartered in Beijing, the company offers fully immersive one-on-one English language instruction provided online by highly qualified teachers.

 @Philip Taylor The point is that this is design is specialized job and is not just a side job. Just because an individual may know a thing or two about the technical aspect of a program does not warrant them to fill that role as a designer. There’s more than just drawing a mark in a program. There’s strategy in brand development, marketing, etc… This is insulting to the creative industry to label logo and branding as a scheme to make extra money.
Get paid for your opinions. Taking surveys online can be a relatively quick way to earn enough to afford a few extras. Harris Poll Online, for example, awards points for the completion of online surveys, which can take between five and 25 minutes to fill out. Survey takers accumulate points and can redeem them for gift cards from retailers such as Amazon and Starbucks. Other online outfits that will pay you to take surveys include SurveyClub, Global Test Market and Swagbucks. There's no cost to sign up.
Cafe Press: This website allows you to create digital designs that can then be sold on the platform. You'll earn a commission for everything that sells and you'll never have to deal with printing, warehousing, customer service and so on. The site has over 2 million independent designers that have created products being sold online here. If you have some graphic design skills, then this is a great potential source for your web-based income. 
5. Fiverr – Fiverr is a great place to make a few bucks or spend a few bucks if you need some of the services people offer. Basically, everything is $5. You either pay $5 or charge $5. They call them “gigs.” You can offer your services however you choose. If you sell art and you’re fine selling pieces for $5 each, that’s a gig. If you’re a graphic designer and you want to offer your services for $10/hour, simply offer a 30 minute gig. If they need two hours of graphic design, they pay you $20, or $10/hour by buying four gigs.
Set up the site. Choose a website building platform, such as WordPress, Joomla or Drupal. Next, choose a domain name and web hosting for your site. The domain name is your web address. Web hosting is a service that connects your site to the internet. Once you have your domain name and web hosting, go to the control panel of your hosting account and install your website platform. Design your website by choosing and installing a theme.[9]
Prior to that group, they had an online community for teachers looking for lesson plans. That probably sounds pretty random, but it's crazy the type of communities you can build and rally people around. If it's something that you're passionate about yourself and you want to connect with others that have that same passion, then an online community is something you should definitely consider.
