Painting with LEDs and a wiimote

Think Big

leave a comment »

Back to work, the time I can spend on the liightbrush is now seriously limited. Nonetheless, the v2 is on the way, with almost 7 times more LEDs (as shown below) and wireless connection to the PC through bluetooth. I am still looking around for proper material to scatter the light. Most parts should be in late this week, and I am targeting to get the work done by the end of next week.

Music at the crossing

leave a comment »

A request for an animal crossing character came in, which I couldn’t refuse. This picture teaches something valuable: a black background on a picture isn’t always as black as I would want it to be. I need to ensure that it is true black in order for it to be completely transparent, otherwise there might be some lost pixels, basically black to the eye but that get translated to colored LEDs nonetheless, as seen with the blue dots below.

As a bonus (lucky you), here is a mix of yesterday’s two pictures.

Confined spaces make the picture that much more real thanks to the reflections, but at the same time that much more surreal (go figure). The picture below is named “got lost?”, because giving it a name just make it seem like it’s art.

Neighbors are beginning to wonder what are these flashing lights at night. And when there’s something strange in the neighborhood, who are you gonna call? (thanks Nicolas for the idea).

The good Dr Zoidberg did not get the proper picture he/it deserved. Now, it’s done.

Looking ridiculous

…ly fun, of course. After getting many (almost 2) questions regarding how exactly was the painting done, here is a brief dark/shaky cam video showing the whole process.

 

That is what the result looks like:

(before anyone tries to do a frame by frame match of the video with the picture, this picture was not taken on the same run)

A delicate balance

with one comment

Colors and contrast of the light paintings are highly sensible to ambient lights. It is quite difficult to find the correct amount of lighting for good rendering, when aiming at twilight to get dim natural light, the window of opportunity is very limited. Here is the best I could manage tonight.

And here is an example of how washed out the colors look if you have too much lighting around.

In broad daylight

leave a comment »

Rainy day at the beach… not much to do, and I don’t feel like waiting for the sun to go down in order to continue my little experiments. Good reasons altogether to try light painting in (almost) broad day light, meaning inside an apartment during a storm. Here’s the result, looking pretty good to me.

I’ll be on the train most of the week end, but expecting to start working on the next phase (putting all I’ve learned together) when I arrive.
