AI Portrait Sketch Generator Display Kit with ESP32 + Stepper Motor
AI Portrait Sketch Generator Display Kit with ESP32 + Stepper Motor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Watch as an ESP32-CAM snaps your photo, transmits it to a cloud-based AI API, and a precision pen plotter draws a stylized vector portrait on paper — a live intersection of computer vision, generative AI, and motion control. This kit turns a simple idea into an interactive art installation that blends creativity with cutting-edge hardware.
What You'll Build
You'll assemble a standalone device that captures a face, processes it through the Anthropic API to generate an SVG sketch, and then uses dual stepper motors and a servo to draw the portrait stroke by stroke. The final machine becomes a captivating demo for tech-art exhibitions, maker portfolios, or deep-dive explorations into real-time AI integration.
What You'll Learn
- Integrate ESP32-CAM with cloud-based AI APIs for image-to-SVG conversion
- Control dual NEMA 17 stepper motors and a servo for accurate pen movement
- Implement G-code-like motion planning using CNC shield and A4988 drivers
- Debug latency, alignment, and pen pressure challenges in AI-driven plotting

Who This Kit Is For
This advanced kit suits final-year B.Tech ECE/EEE students from IITs, NITs, VIT, or BITS Pilani crafting AI-mechatronics capstone projects; tech artists building interactive installations for exhibitions; and professionals prototyping AI-driven hardware for Smart India Hackathon or research labs. If you already have experience with MCUs and basic soldering, this plotter will push your skills into generative AI and precision motion control.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on your kit box to launch the AI companion; it understands this exact build. If you need human help, WhatsApp our support team — they typically reply within hours.
Does the kit include an AI API key or subscription?
No, you need to sign up for a free-tier Anthropic API account. Our build guide clearly shows how to generate a key and link it to the ESP32 firmware.
Can I modify the drawing style or use a different AI model?
Absolutely. The open-source firmware lets you edit the SVG generation prompt to alter line art style, or swap the Anthropic endpoint for any compatible image-to-SVG service. All code is documented.
What pen and paper work best with this plotter?
The spring-loaded holder fits standard fine-liner pens (0.5–1.0 mm) and draws on A4 or smaller paper clipped to the base. You can experiment with gel pens, markers, or brush pens for different artistic effects.
ESP32-CAM captures face, sends to Anthropic API, returns SVG sketch, stepper plotter draws it on paper.
