light painting

Light painting seems a logical progression to the led pov sticks. As the WS2811 leds aren’t too good for the POV work, I thought that I may as well use them for something else. They are fine for use in slower moving projects and static projects so I put together a light staff for light…

ws2811 and POV

well, I have been experimenting with using the ws2811 high density strips for persistence of vision batons (pixel poi) using the Teensy3 to run the show. Unfortunately, the chips inside the WS2811 leds just aren’t fast enough, as you can see from the image below: the problem is that the frequency of PWM is too…

FastSPI_LED2 Teensy 3 and const array access

So, I am moving my Graphic (Pixel) POI over to using a different LED and Microprocessor. The reason for this is to experiment with using a high density prebuilt strip of LEDs. These strips are 144led/m, individually addressable. To do this I need to use the new driver library for FastSPI. The new library is…
