ChatGPT for Hardware: Generate Physical Prototypes

UX vision

Simply drop in the datasheets for all the parts you're using, and GPT will:

• Generate firmware and wiring schematics to get you started.

Or describe your product vision, and it will:

• Suggest parts to use.
• Generate breadboard designs to help you create the first prototype.

Firmware

Generate firmware that will work using the suggested or selected parts

• Automatically finds the right libraries for your specific hardware architecture.
• Writes a program using those libraries.
• Produces test sketches to verify each component one at a time to help with wiring debugginga.

Hardware Awareness

The AI would need to understand implementation-specific details, such as:

• Detecting a satellite chip’s primary data interface (I2C, SPI, etc.)
• Looking up necessary additional hardware (pull-up resistor values, decoupling capacitors)
• If no values are found, defaulting to common values (e.g., 4.7kΩ, 100nF).
• A convention library would be used to inform design decisions.

Breadboard & PCB Support

The tool would default to breadboard mode and produce:

• Graphical wiring schematics for breadboards.
• The ability to easily convert designs into a PCB generator and have some sort of lcsc auto component selection to make jlc ordering and assembly super easy.

Example Use Case

This tool is designed for makers, like Elia building a VR vibration wristband, rather than professional engineers designing complex PCBs.

Example Prompt

Prompt: "I want to make a vibrational wristband that I can trigger with my laptop."

AI-Generated Output:

• Suggested Parts (with images and purchase links):
  • ESP32
  • Haptic motor driver
  • Coin-style haptic motor
• Suggested Project Structure:
  • ESP32 interfaces with the computer via Bluetooth.
  • Generates a block diagram showing component integration.
• Wiring Diagram:
  • Shows how to connect everything on a breadboard.
  • Includes an optional LED for debugging, with an explanation of its purpose.
• Firmware Files (for MCU (arduino, etc.)):
  • File 1: "Hello, World" test to verify wiring (LED blink, driver initialization).
  • File 2: Firmware with "building block" functions that utilize library drivers to provide simplified functionality to the user.
• Python Script (for laptop):
  • Interfaces with the laptop's Bluetooth chip.
  • Sends commands to trigger pulses on the wristband.

Existing AI PCB Generator

One example is Flux AI, but it's designed for users already experienced with PCB design, not beginners.

While AI-powered PCB generators exist, this tool would:

• Suggest components.
• Generate prototype designs and firmware that work out of the box.
• Enable rapid iteration for makers and hardware enthusiasts.
