CartoLucci: A Candle-Powered Christmas Card


If you’re looking for a last-minute Christmas present, you probably won’t have enough time to reproduce [Helmar’s] candle-powered Christmas card. He’s been working on it for a few years now, since his first prototype in 2010.¬†Though he pieced together the original card with parts lying around his workshop, the most recent iteration looks like it belongs on the shelf in a store.

We last saw [Helmar’s] work two years ago, when he shared his Full Color Laser TV. This project is a bit more compact: the circuitry was printed with conductive ink on the cardstock, and all the required components are held together by conductive adhesive. To power the electronics, he decided against a battery and instead chose to embed a solar cell on the inside of the card. Placing a lit candle inside the open card provides enough juice for the exterior of the card to shine.

You can see a video of both the current and prototype versions of [Helmar’s] cards after the break.

          1. There’s some sort of idea in there for “this message will self-destruct”. An audio message stored in paper electronics, powered by it’s own catching fire.
            Maybe print a few thermocouples in there.
