Four Meter Light Paintings

HaD

We’ve seen some light painting before – waving a microcontroller and LED strip in front of a camera is a very interesting project after all. [Saulius]’ light painting stick is unlike anything we’ve seen before, though. It’s huge – four meters high, and is also very flexible in the field, drawing images served up from a smart phone.

To get his pictures onto his light painting stick, [Saulius] used the very cool Carambola, an exceedingly small board that also runs Python. The images were converted to a 128xWhatever .BMP file served to the Carambola over WiFi with a smart phone, Since the Carambola runs Linux, sometimes a kernel interrupt would mistakenly restart the drawing process. [Saulius] found a way around that by writing the drawing code in C and wrapping that in a Python module. The speed of C and the flexibility of Python, who could ask for more.

On the project page, you can see [Saulius] pulling off some very cool light paintings. Even though the Hackaday logo is the best way to get on the front page here, this pic is probably the most impressive

    1. Labas, Sauliau! Cool project, thanks for sharing. I’ve lurked here six years and this is my first time posting. I took pictures at the base of Gedimino hill and all through old town while visiting friends in Vilnius earlier this summer. Carry on!

  1. Its funny how people who build stuff like this, never have any clue of photography, compositionor lightpainting per se. I mean the images are ridiculous, but i respect the code and building.
