Build a flickering desktop candle that recharges using solar power and automatically illuminates when the lights go down.
No prior knowledge required!
Solar Energy & Harvesting: An approachable breakdown of photovoltaic solar panels and how light energy is captured and stored in rechargeable batteries.
Light Sensors & Automation: Exploring how light-dependent resistors (photocells) allow circuits to automatically turn on at dusk and off at dawn.
Circuit Assembly & Wiring: Hands-on experience connecting solar modules, charging circuits, and flickering LED components inside a custom enclosure.
Recommended Ages: Middle school, high school, and adults (Ages 11+).
Skill Level: Beginner friendly—no prior electronics, solar, or technical background required.
Ideal Event Types: STEAM programming, library maker sessions, sustainability/green tech workshops, and adult tech literacy sessions.
Max Attendance: up to 30 participants
First 15–30 Mins – Tech Intro & Discussion
An engaging opening discussion on clean energy, how solar panels generate electricity from light, and how simple sensors automate modern outdoor lighting.
Next 45 Mins – Guided Hands-On Build
Step-by-step guided assembly where attendees wire the solar panel, rechargeable circuit module, light sensor, and flickering candle LED inside a custom enclosure.
Final 15 Mins – Testing, Customization & Wrap-Up
Covering the light sensor to test automatic night-activation, verifying solar charging connections, troubleshooting wiring, and packaging up the completed project.
