Hart Mesh Learning Initiative
The Mesh Learning Initiative (MLI) seeks to introduce elementary, middle and high school students to cutting-edge communication technology through the use of Meshtastic devices. These devices, based on open-source LoRa (Long Range) technology, allow students to explore practical applications in wireless communication, electronics, and programming. The program will provide students with hands-on experiences in building their own communication networks and learning about the impact of wireless technologies on real-world issues like disaster response, remote communication, and environmental monitoring. This project aligns with our mission to equip students with essential STEM skills while fostering teamwork, problem-solving, and innovation.
This initiative has partnered two other campuses, Gus Garcia YMLA and LBJ High School. Each program has a dedicated node and program name:
Hart: HMLI- Pronounced Him-Lee
Gus Garica: GMLI- Pronounced Gim-Lee
LBJ: LMLI- Pronounced Lim-Lee
In addition to our campus partners, we also have partnered with 3M, Oracle, AnyCubic, and the University of Texas communication department for support.
Our largest partner is the Austin Mesh, a community driven project with over 450 members. This group represents a wide range of expertise that includes 3d design/printing, radio/IT communication, electronics, and much more. You an learn more about their mission and ongoing projects at their website
The MLI is broken down into 3 Phases
Phase 1: Introduction to Wireless Communication and the Meshtastic System
-
Students will be introduced to the basic concepts of wireless communication, radio frequencies, and the use of LoRa technology.
-
They will learn about the Meshtastic devices, how they work, and how they can be used to create a mesh network.
-
This phase includes building and deploying HMLI,GMLI, and LMLI nodes to connect the campuses, and then connect to the greater mesh network
2. Phase 2: Hands-On Workshops and Device Setup
-
In small groups, students will assemble Meshtastic devices, solder components, and configure the devices for use in a mesh network.
-
Students will write simple code to control the devices and establish communication between them.
-
This phased includes regular radio communication checks with the partner campuses, designing and testing new deployment systems (pole mounts, magnetic mounts, etc.) This phase will also include the development and integration of solar power systems in to HMLI,GMLI, LMLI nodes.
3. Phase 3: Real-World Applications and Problem-Solving Challenges
-
Students will be given real-world scenarios where they must use the Meshtastic devices to create a reliable communication network.
-
Challenges may include simulating a disaster response situation or setting up remote communication systems in an area with no cellular service.
-
Students will present their findings and solutions to the class.
-
This phase will include development and deployment of weather telemetry systems into HMLI, GMLI, LMLI nodes allowing for weather data tracking for student projects and be shared in real time with National Weather Service.
