My Kickstarter failed, so I open sourced it

Summary

In this engaging video, the creator revisits a failed Kickstarter project after discovering an old project box. Inspired by this, they aim to remake it with an open-source approach using ESP32 technology for easier accessibility. The project features a 3D-printed car with minimal moving parts, a color sensor, and a magnetic switch to enhance functionality. A neural network is integrated to process color data, enabling Mario Kart-inspired game mechanics. After overcoming challenges in assembly and design, the project culminates in a fun, interactive toy for kids, with all design files available for others to recreate.

Q & A

What inspired the creator to revisit their old Kickstarter project?

The creator found their old Kickstarter project materials while organizing and felt inspired to recreate and improve upon the original design, making it open-source.

Why did the creator switch from an ARM microcontroller to the ESP32?

The ESP32 is more affordable, easier to use, and has a larger community support compared to the ARM microcontroller and Bluetooth module used in the original project.

What are the key features of the new 3D printed car design?

The new design focuses on simplicity, minimal moving parts, integration of a color sensor and a magnetic switch to prevent false triggers, LED lights for realism, and a rechargeable battery system.

How does the magnetic switch function in the project?

The magnetic switch prevents the color sensor from triggering unnecessarily when the car is on a colored surface, allowing it to only activate based on specific conditions.

What is the significance of using a LiPo battery in the project?

LiPo batteries provide a quick power draw and recharge, making them suitable for powering the car while simplifying the charging process with a built-in circuit.

What challenges did the creator face while 3D printing the car components?

The creator struggled with printing precise components, especially the wheels, which required switching to a resin printer for better accuracy after several failed attempts.

How does the creator plan to implement AI in the car project?

The creator designed a neural network that processes data from the color sensor, allowing the car to recognize different colors and respond with actions inspired by Mario Kart gameplay.

What type of game logic is used in the car's functionality?

The car's game logic includes elements like speed boosts and spin-outs, triggered by specific colors and shapes that correspond to actions similar to those in Mario Kart.

What materials and tools did the creator use for assembly?

The assembly involved using a pick-and-place machine for efficiency, double-sided tape for securing components, and 3D printed parts for the car and controller.

What is the final goal of the project for the creator and their family?

The creator aims to provide an engaging and educational experience for their kids, encouraging creativity and interaction through play with the completed car project.
