42 Open source and cheap radiosonde

Yamuna Phal proposal
We would like to make a cheap, open source weather radiosonde. Currently, radiosondes are launched in 92 different locations 365 days a year and cost upwards of $250. When they drop back to the surface, the radiosonde is rarely ever recovered and reused.

We would like to develop a prototype that offers a locating functionality. The radiosonde will consist of temperature sensors, barometer, humidity sensor, transmitter and receiver with a quarter wave antenna. In addition to transmitting pressure, temperature and humidity readings, the prototype will offer an option to add an additional sensor to measure research data such as carbon dioxide levels in the air to determine air quality and track variations.

Amphibious Spherical Explorer

Featured Project

The amphibious spherical explorer (ASE) is a spherical robot for home monitoring, outdoor adventure or hazardous environment surveillance. Due to the unique shape of the robot, ASE can travel across land, dessert, swamp or even water by itself, or be casted by other devices (e.g. slingshot) to the mission area. ASE has a motion-sensing system based on Inertial Measurement Unit (IMU) and rotary magnetic encoder, which allows the internal controller to adjust its speed and attitude properly. The well-designed control system makes the robot free of visible wobbliness when it is taking actions like acceleration, deceleration, turning and rest. ASE is also a platform for research on control system design. The parameters of the internal controller can be assigned by an external control panel in computer based on MATLAB Graphic User Interface (GUI) which communicates with the robot via a WiFi network generated by the robot. The response of the robot can be recorded and sent back to the control panel for further analysis. This project is completely open-sourced. People who are interested in the robot can continue this project for more interesting features, such as adding camera for real-time surveillance, or controller design based on machine learning.
