Have you ever wanted to build something but you had no idea what to do? Just as authors sometimes have “writers block” it’s also true for developers.
This is not just a simple list of projects, but a collection that describes each project in enough detail so you can develop it from the ground up!
Each project specification contains the following:
All of the projects are divided into three tiers based on the knowledge and experience required to complete them. These tiers are:
Below you’ll find 5 projects for each of the tiers (15 in total), but there are over 30 projects (at the moment) in this GitHub repository. We are adding more projects periodically and you are welcome to help! (More about this in the Contributing section below 😉)

Description: The ChristmasLights application relies on your development talents to create a mesmerizing light display. Your task is to draw seven colored circles in a row and based on a timer change the intensity of each each circle. When a circle is brightened it’s predecessor returns to its normal intensity.
This simulates the effect of a string of rippling lights, similar to the ones displayed during the Christmas Holidays.
Description: It’s important for Web Developers to understand the basics of manipulating images since rich web applications rely on images to add value to the user interface and user experience (UI/UX).
FlipImage explores one aspect of image manipulation - image rotation. This app displays a square pane containing a single image presented in a 2x2 matrix. Using a set of up, down, left, and right arrows adjacent to each of the images the user may flip them vertically or horizontally.
Description: Practice and test your knowledge by answering questions in a quiz application.

Description: The purpose of String Art is to provide the developer with practice creating a simple animated graphic, using geometry in the animation algorithm, and creating something that’s visually pleasant to watch.
String Art draws a single multicolored line which smoothly moves until one end touches a side of the enclosing window. At the point it touches a “bounce” effect is applied to change it’s direction.
A ripple effect is created by only retaining 10-20 images of the line as it moves. Older images are progressively faded until they disappear.
This project is very close, but has a small enclosing window and is monochromatic. Daniel Cortes
Description: The classic To-Do application where a user can write down all the things he wants to accomplish.

Description: Battleship Game Engine (BGE) implements the classic turn-based board game as a package that’s separated from any presentation layer. This is a type of architectural pattern that useful in many application since it allows any number of apps to utilize the same service.
The BGE itself is invoked through a series of function calls rather than through directly coupled end user actions. In this respect using the BGE is is similar to using an API or a series of routes exposed by a web server.
This challenge requires that you develop the BGE and a very thin, text-based presentation layer for testing that’s separate from the engine itself. Due to this the User Stories below are divided two sets - one for the BGE and one for the text-based presentation layer.
BGE is responsible for maintaining game state.
startGame()function to begin a 1-player game. This function will generate an 8x8 game board consisting of 3 ships having a width of one square and a length of:
startGame()will randomly place these ships on the board in any direction and will return an array representing ship placement.
shoot()function passing the target row and column coordinates of the targeted cell on the game board.
shoot()will return indicators representing if the shot resulted in a hit or miss, the number of ships left (i.e. not yet sunk), the ship placement array, and an updated hits and misses array.
Oif they were targeted but no part of a ship was at that location, or
Xif the cell was occupied by part of a ship.
startGame()which will generate one board for each player randomly populated with ships.
shoot()will accept the player number the shot is being made for along with the coordinates of the shot. The data it returns will be for that player.
statsin place of target coordinates. (Note that this requires the
gameStats()function in the BGE)

Description: API’s and graphical representation of information are hallmarks of modern web applications. GitHub Timeline combines the two to create a visual history of a users GitHub activity.
The goal of GitHup Timeline is accept a GitHub user name and produce a timeline containing each repo and annotated with the repo names, the date they were created, and their descriptions. The timeline should be one that could be shared with a prospective employer. It should be easy to read and make effective use of color and typography.
Only public GitHub repos should be displayed.
GitHub offers two API’s you may use to access repo data. You may also choose to use an NPM package to access the GitHub API.
Documentation for the GitHub API can be found at:
Sample code showing how to use the GitHub API’s are:
You can use this CURL command to see the JSON returned by the V3 REST API for your repos:
curl -u "user-id" https://api.github.com/users/user-id/repos
Description: Knowing how to spell is a fundamental part of being fluent in any language. Whether you are a youngster learning how to spell or an individual learning a new language being able to practice helps to solidify your language skills.
The Spell-It app helps users practice their spelling by playing the audio recording of a word the user must then spell using the computer keyboard.
Description: Surveys are a valuable part of any developers toolbox. They are useful for getting feedback from your users on a variety of topics including application satisfaction, requirements, upcoming needs, issues, priorities, and just plain aggravations to name a few.
The Survey app gives you the opportunity to learn by developing a full-featured app that will you can add to your toolbox. It provides the ability to define a survey, allow users to respond within a predefined timeframe, and tablulate and present results.
Users of this app are divided into two distinct roles, each having different requirements:
Commercial survey tools include distribution functionality that mass emails surveys to Survey Respondents. For simplicity, this app assumes that surveys open for responses will be accessed from the app’s web page.
Libraries for building surveys:

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.
Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.
There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.
To give you an idea of how long the app development process takes, here’s a short guide.
_Average time spent: two to five weeks _
This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.
All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.
Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.
The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.
The outcomes of this stage are app prototypes and the minimum feasible product.

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?
Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.
Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.
To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.
What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.
You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.
Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.
You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.
You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.
As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.
Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.
As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.
All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.
This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!
Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.
Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.
What advantages can you get from micro-mobility? Let’s take a deeper look into this question.
Micro-mobility can offer several advantages to the people on your campus, e.g.:

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.
Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.
In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.
A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.
And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.
Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.
It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.
