A simulator for sketching and testing mesh network routing strategies

hacked library and test sketch for controlling blackmagic micro cameras from an arduino over sbus

I do sketches in Grasshopper and Three.js, the former I use to test out architecture concept, whereas the latter is just for the pleasure of interactive visual effects on web. Feel free to use it for your own purpose. I'd be happy if anything from my sketches can contribute to your own work!

This Arduino sketch (WIP) turns an ESP32 into a dynamic Pwnagotchi trainer, generating random Wi-Fi networks, broadcasting beacon frames, and hopping channels to simulate real-world conditions. It helps Pwnagotchis learn to detect, deauthenticate, and capture handshakes, boosting their penetration testing skills.

This Arduino sketch expands the SBUS using an Arduino such as a small Ardiono Nano or ProMicro making the full 16 channels available on your FrSky compatile RC receiver (such as the XR8 or XR4) which would otherwise be limited to just a few PWM ports. This sketch gives additional possibilities with your RC projects such as proportional or pre-set control of servos, switching on landing lights, ativiating buzzers, launching parachutes, reading sensors on your RC model as remote telemetry data, etc. How it works? The arduino sketch merely "sniffs" the SBUS data arriving on the serial port and split the package into 16 channels. You are then able to configure and map the Arduino pins to any available RC channel as you like. It's only limited to the number of channels and the number of free I/O ports on your Ardiuno. The Arduino can be added 'in-line' with any other SBUS device on your RC model. Please note that only limited testing has been done on using various RC cars and drones. so don't use this device for any critical or non-critical control of your model without thorough testing. You use the solution and code at your own risk.

A single player game in SpriteKit created completely programmatically without the use of .sks files and Xcode Scene Editor. Implemented continuous integration using Jenkins, Fastlane GitHub, and Unit Tests into one continuous integration system. So everything is automated from the first commit to the email notification at the end from Jenkins when the build finished. I used Firebase as a backend and implemented its Sign up/Login with Facebook and Anonymously into the app, and saved users data like: UID, email address, username and profile image into Firebase Database and Firebase Storage, likewise, I implemented a persistent store so all user data is saved after the user quits the app. During the development of the app, I followed the MVC design pattern, likewise, I used Sketch for creating most of the UI.

An AI-based mobile application that is able to diagnose Parkinson's Disease using two independent tests that require only a pencil and a paper. Based on the 2017 research paper Distinguishing Different Stages of Parkinson's Disease Using Composite Index of Speed and Pen-Pressure of Sketching a Spiral by Zham et. al. The trained models were deployed using a Flask backend server, along with a Flutter based frontend mobile application frontend to interact with the REST API.

# Employee Database: A Mystery in Two Parts  ## Background It is a beautiful spring day, and it is two weeks since you have been hired as a new data engineer at Pewlett Hackard. Your first major task is a research project on employees of the corporation from the 1980s and 1990s. All that remain of the database of employees from that period are six CSV files. In this assignment, you will design the tables to hold data in the CSVs, import the CSVs into a SQL database, and answer questions about the data. In other words, you will perform: 1. Data Modeling 2. Data Engineering 3. Data Analysis ## Instructions #### Data Modeling Inspect the CSVs and sketch out an ERD of the tables. Feel free to use a tool like [http://www.quickdatabasediagrams.com](http://www.quickdatabasediagrams.com). #### Data Engineering * Use the information you have to create a table schema for each of the six CSV files. Remember to specify data types, primary keys, foreign keys, and other constraints. * Import each CSV file into the corresponding SQL table. #### Data Analysis Once you have a complete database, do the following: 1. List the following details of each employee: employee number, last name, first name, gender, and salary. 2. List employees who were hired in 1986. 3. List the manager of each department with the following information: department number, department name, the manager's employee number, last name, first name, and start and end employment dates. 4. List the department of each employee with the following information: employee number, last name, first name, and department name. 5. List all employees whose first name is "Hercules" and last names begin with "B." 6. List all employees in the Sales department, including their employee number, last name, first name, and department name. 7. List all employees in the Sales and Development departments, including their employee number, last name, first name, and department name. 8. In descending order, list the frequency count of employee last names, i.e., how many employees share each last name. ## Bonus (Optional) As you examine the data, you are overcome with a creeping suspicion that the dataset is fake. You surmise that your boss handed you spurious data in order to test the data engineering skills of a new employee. To confirm your hunch, you decide to take the following steps to generate a visualization of the data, with which you will confront your boss: 1. Import the SQL database into Pandas. (Yes, you could read the CSVs directly in Pandas, but you are, after all, trying to prove your technical mettle.) This step may require some research. Feel free to use the code below to get started. Be sure to make any necessary modifications for your username, password, host, port, and database name: ```sql from sqlalchemy import create_engine engine = create_engine('postgresql://localhost:5432/<your_db_name>') connection = engine.connect() ``` * Consult [SQLAlchemy documentation](https://docs.sqlalchemy.org/en/latest/core/engines.html#postgresql) for more information. * If using a password, do not upload your password to your GitHub repository. See [https://www.youtube.com/watch?v=2uaTPmNvH0I](https://www.youtube.com/watch?v=2uaTPmNvH0I) and [https://martin-thoma.com/configuration-files-in-python/](https://martin-thoma.com/configuration-files-in-python/) for more information. 2. Create a bar chart of average salary by title. 3. You may also include a technical report in markdown format, in which you outline the data engineering steps taken in the homework assignment. ## Epilogue Evidence in hand, you march into your boss's office and present the visualization. With a sly grin, your boss thanks you for your work. On your way out of the office, you hear the words, "Search your ID number." You look down at your badge to see that your employee ID number is 499942. ## Submission * Create an image file of your ERD. * Create a `.sql` file of your table schemata. * Create a `.sql` file of your queries. * (Optional) Create a Jupyter Notebook of the bonus analysis. * Create and upload a repository with the above files to GitHub and post a link on BootCamp Spot.
