The fourth version of the RC car PCB builds upon the third version by switching to a ceramic antenna and utilizing a four-layer PCB design.

My inspiration comes from this piece (blot.hackclub.com/editor?src=https://raw.githubusercontent.com/hackclub/blot/main/art/2DLight-Will/index.js). My first thought was that it seemed to be blocking the light coming from the center, so I thought I could create an opposite work—one that enhances the energy coming from the center. My theme is water wave diffraction. When water waves pass through a slit, they create diffraction, which adds curves to the originally uniform parallel waves. I added lines perpendicular to the wavefront to enhance the sense of radiation.

This time, I created the third version of the remote control car PCB. The goal was to make the PCB as small and inexpensive as possible. Due to the reduced size, I had to spend more time on layout and routing. Additionally, my lack of knowledge regarding RF ICs and antennas led to several issues during this part of the design. They took up a significant amount of space, and I believe there is still room for improvement. I plan to optimize this aspect of the design in the next version.

I originally planned to use the MSP430 to make an oscilloscope, but due to certain issues, I decided to switch to the ESP32.
The next step for this project might be to add external circuitry to reduce noise.

I attempted to create an oscilloscope using the MSP430, but after numerous tests, I still couldn't read any data through the serial interface. I suspected it might be a hardware or configuration issue. Ultimately, I decided to switch to using the ESP32 for building the oscilloscope. Despite this setback, I believe the experience was valuable, as I learned a lot about the principles of oscilloscopes.

#arcade I made a PCB for a remote control car, featuring an ESP32-C3 as the main control chip, a USB-C interface, and the ability to control two motors.

This summer, I want to go out with my friends, but it's very troublesome to figure out everyone's availability.So, I want to set up a website where my friends can enter their available times.
