Images must be captured using a DSLR or other camera that has a long exposure setting and can only be captured in darkened rooms or at night. Designs need to be set up in Photoshop or some other graphic editing program. "Whether they've been slinging light since the Nixon years or they're just beginning, there doesn't seem to be any one thing that ties us together other than a love of the elegant and unpredictable nature of light."Īt $300, Pixelstick is an affordable luxury for photographers, but a steep learning curve could make it difficult for it to reach the mainstream. "If you search for light painters on Flickr, Tumblr, or Twitter, you'll see people of all ages, from all over the world," he says. Pixelstick quickly blew past its $110,000 goal on Kickstarter and has attracted nearly 1,000 backers, but according to Frazier, there aren't many common threads between practitioners of this flashy artform. The pair had been experimenting with long-exposure photography for years and wanted to move beyond the flashlights, iPhones, and other improvised light sources they had been using to sketch to something that offered more creative control. It's a collaboration between Steve McGuigan, a creative jack-of-all-trades and Duncan McCloud Frazier, a photographer/programmer. When loaded with graphics files and waved in front of a camera that has long-exposure capabilities, it creates illuminated images-rainbow swirls, ethereal graffiti, 8-bit animated GIFs, and even masterworks like Botticelli's Venus-that seem to hang in the air like ghosts. In a more technical sense, it's a 6-foot-long aluminum rod, housing a strip of 198 LEDs. Pixelstick is a modern magic wand, and by waving it in a darkened space creatives can conjure fearsome creatures, potent glyphs, and streaks of energy that seem to move under their own power. This one does require a PCB which I plan to make available soon.Pixelstick, a new gadget for light painters, gets loaded up with graphics, waved in front of a camera that has a long exposure capabilities, and creates illuminated images-even animated gifs-that seem to hang in the air like ghosts. I have designed a new and improved version, see The pixel address reversal is handled in the software because otherwise the bottom LED's would be upside down! So both LED's are connected in the middle. This is because I wanted to avoid running the wires down the length of the LED strip. One reader noticed that I didn't explain that the bottom LED strip (led1) is connected by the handle, not down at the bottom. These cards do not fit in the case! The Heltec units I've ordered from Amazon were original Heltec models and fit perfectly. The picture showed the Heltec devices, however the devices they sent were a cheap clone that has the display mounted flat on the board instead of on the plastic spacer. I recently ordered some ESP32 WIFI HELTEC kits from. If you build one of these without using the new PCB (which nobody except me has anyway so far!) make sure to comment out this line. Some of the wiring changed so there is an important change in the sketch. I am working on a new version with a PCB that also mounts the switch. Please let me know if I have missed any of the files or if I need to add more details or photos. You could also just solder the wires in the holes instead of using the jumper wires that I used for the first prototype. I mounted 90 degree angle pins on the ESP32 so I could put the wires on sideways. It is a bit of wiring but I made one that works from the wiring diagram. It has mounts for the SD reader, the level shifter, and the ESP. I added the STL file for the no PCB version. You can wire it by hand, or if you're interested I have designed a PCB holding the components that makes assembly much easier. It can be used with either 1 meter with 144 pixels, or two meters with 288 pixels total. You can control the painter with a single hand! It rotates to make selections and clicks to choose things. Instead I added a single dial/button that is in the handle. I originally used the touch screen like others but after use I felt it was too clumsy to use. I redesigned it using an ESP32 with a built-in display. Like many others I started building this thing with an Arduino Mega but I soon ran into memory and speed issues. I have attached a pdf file with a lengthy description of all the features of this design. Do a Web search for "pixelstick images" to see lots of example of what can be done with this tool. This is a feature rich variation on the PixelStick used for light painting photography.
