About:

This self-powered stipple light display beautifully commemorates a memory between you and your loved ones while operating entirely off the grid. Inspired by Matthew Hamilton's Trichrome Stipple Light project —developed for a lab64 workshop—this lamp combines laser cutting, 3D printing, and hand-soldering surface-mounted components. Under the hood, the lamp leverages an energy harvesting chip with maximum power point tracking (MPPT), analog circuit design, solar panels, and a LiPo battery.

Features:

Stanford lab64 Week 10 MakerSpotlight (12/5/24)

Concepts Utilized:

Maximum power point tracking to optimize solar panel's load impedance to increase harvested energy

Low-power circuit design to enable perpetual operation from solar power alongside a 300 mAh battery

Mechanical CAD design to manufacture 3D printed and laser cut components that fit with the correct tolerances
