![]() ![]() Note that this is very lousy way of blending images. running the octave script in the images directory which will generate "out.jpg".extract frames from recorded video file ("ffmpeg -i my_video-1.mkv -f image2 image-%3d.jpeg").record the scene as video file (I used webcam and guvcview app).Since this is a quick and dirty hack I created an ad-hoc method for this using the following steps: Using any approach should give better results than the following method :D. This approach is simpler and there are apps for mobile phones for that (haven't tested any of them). Another approach is to combine lot of short exposure photos. Getting the final imageīest results can be obtained by using long exposure on DSLR camera. ![]() It just resizes image to the height of 32px, saturates colors (arduino code does not use PWM so we have only few colors available) and creates arduino code that can be copied directly to arduino IDE ( Adafruit HL1606 library needs to be installed).Ĭurrent code is limited to 32 RGB leds (1m of LED strip). To convert image to arduino code I created very simple web app located at. DI, CI and LI pins from the strip are connected to arduino pins 5, 6 and 9 (it is also possible to connect it to SPI pins for faster communication) and Adafruit hl1606 library is used. The whole device consists of an arduino, LED strip and a power supply (batteries are recommended). I had a RGB LED strip with HL1606 drivers laying around so decided to make this quick and dirty hack. The whole idea is to paint the picture row by row (or column by column). This is very simple device for light painting on long exposure photos, inspired by pixelstick. ![]()
