Pixelstick images text4/11/2023 ![]() ![]() The numbers indicate the cursor locations and dynamic information locations. Menu File ExplanationĮach menu file contains a list of numbers and the strings that should be displayed on the LCD. In this case the HSV values are converted to RGB before entering the RGB menu to preserve the color. ![]() The function that executes when the user enters a menu often adjusts the encoder counts so that they will have certain default or saved values when the menu loads.Īn example of the back button is when the user goes from HSV color selection back a menu to select RGB color selection. The list contains a function to execute continually while that menu is being displayed, a function that runs when that menu is entered, and function to run when that menu's back button is hit.įunctions that run continually would be things such as updating the LED string when making the general shape of a new wand or band pattern. Each struct contains an array of other indices in the menu table corresponding to it's parent menu and submenus as well as a list of 3 function pointers. See Menus.h, each menu has a corresponding menu struct organized in a large menu_table. That cost can be drastically lowered if a sparser LED strip is used since that is the main expense (I used two strips of 144 LEDs 1m long). Read this documentation and if you still have questions contact me ( UI is not very intuitive which tends to happen when you are controlling complex LED patterns via three encoders and an LCD.ĭespite my attempts to keep the financial cost low I still ended up spending upwards of $100 on this project. Multiple fonts supported as well as bold and italizied versions of those fonts.Ĭoming soon! (hopefully) Upload any image and have the pixelstick display that image as it is moved at a constant rate. Examples:ĭisplay any custom color on any portion of the stick (a wand).ĭisplay any pattern of colors or their repetition over the length of the whole stick (a band pattern).Īdd any custom string and display the text as the pixelstick is moved at a constant rate. The first company to make one is here: and they have an up and coming competitor here: but I built one myself for fun. But it also has some good creative potential to be used as a more 'traditional' light painting tool and I'm interested in exploring ways to integrate it with other, home made light painting devices.It's a programmable LED strip for light painting (long exposure photography). It's main appeal is the way in which it allows beginners to quickly produce very interesting results, simply by dragging a bitmap through mid air in front of a camera. As far as I am aware, the Pixelstick is the only purpose built manufactured light painting tool in existence. ![]() I started using addressable LEDs in the days before the Pixelstick existed, using a home made device known as the Digital Light Wand, created using the open source plans of its creator Mike Ross. Using the Pixelstick sort of blurs the line, as it requires bitmaps to be created on a computer, but that lends an interesting twist to the analog/digital blending of elements. What is the appeal with light painting and how does the Pixelstick help?Ī large part of the appeal of light painting is that in an era where computers are frequently used to create images which simulate reality, waving lights at cameras can turn this on its head, and use the real world to create imagery that looks like CGI. It's a highly engaging art-form, and I try to encourage awareness of this via workshops, artist residencies, community arts projects as well as private and commercial commissions. Since then, I've been waving lights at cameras with great gusto on a regular basis. My first attempts at light painting were in the late '80s and early '90s when I used E6 slide film with random light trails as a way to create beams of light when projected in conjunction with a bunch of slide projectors in a nightclub.
