    In this session, we began integrating the motor that will drive the entire clock. We used a stepper motor (28BYJ-48) controlled by an Arduino to achieve precise and slow rotation—one full turn per minute.

    We uploaded a simple test script to rotate the motor exactly 360° in 60 seconds. We mounted the first gear (seconds) directly on the motor shaft and observed its performance.

    The test was successful: the motor ran smoothly and maintained consistent speed. This confirmed that the motor is suitable to serve as the driving force for the entire mechanism. Next, we plan to connect the gear train and observe the transmission to the minute gear.

    Once the gear models were ready, we exported them as SVG files and prepared them for laser cutting. We used 3mm plywood for the prototypes.

    The laser cutter allowed us to produce gears with very precise tooth profiles. We adjusted the power and speed settings to avoid burning or warping the edges. After cutting, we manually sanded and cleaned the pieces to ensure a smooth rotation.

    Seeing the wooden gears come to life was a big milestone—it gave us the first physical components of our future clock. We then began testing the gear meshes to verify alignment and motion transfer.

    With our project back on track, we focused on designing the gear system required to transmit motion from the seconds gear (1 rotation per minute) to the minute gear (1 rotation per hour), and then to the hour gear (1 rotation every 12 hours).

    Due to the constraint that no gear can have more than 60 teeth (because our model will be too big otherwise), we had to carefully calculate the gear ratios. After testing different configurations, we settled on multi-stage gear trains to achieve the necessary reductions.

    Using Fusion 360, we created digital models of each gear and ensured that the teeth meshed correctly. We double-checked the spacing and pitch diameter for each gear pair to avoid slippage or backlash. The result was a clean and efficient gear system that met our timing and mechanical constraints.

    After evaluating the feasibility and educational value of both ideas, we decided to return to our original project: designing a fully mechanical clock. We realized the clock offered more opportunities to apply precise mechanical design, gear calculations, and creative problem-solving.

    In this session, we finalized our commitment to the gear-based clock and started focusing again on the mechanisms that would ensure accurate timekeeping. From this point forward, all sessions will be dedicated to building a reliable, motor-driven mechanical clock.

    Initially, we planned to build a mechanical clock powered by gears. However, after exploring the design details, materials, and complexity involved, we decided to shift our focus towards a new and exciting project: an electric frisbee launcher.

    During today's session, we created detailed plans for our electric frisbee launcher, deciding to use a single motor for simplicity and efficiency. We also began documenting our project on Hackaday. The launcher will operate using a single motor-driven wheel that spins rapidly, transferring kinetic energy to the frisbee and launching it accurately and consistently.

    Today, we made progress on our exciting project of creating a mechanical clock with gears. We started by exploring the details of our project, using Fusion 360 to visualize and design the gears. We also created cardboard models to better understand the structure and operation of our clock.

    Next, we thought about the materials to use, deciding to opt for wood due to its durability and aesthetic appeal. We discussed the number of gears needed and the number of teeth for each gear to ensure smooth and precise operation. 

    We made a sketch and a maquette with cardboard to visualize our project
