This one does require a PCB which I plan to make available soon. I have designed a new and improved version, see
#PIXELSTICK PHOTOS SOFTWARE#
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.
#PIXELSTICK PHOTOS PDF#
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. If you’re interested, jump to Kickstarter official site for more details or check out the following demo video first.This is a feature rich variation on the PixelStick used for light painting photography. At the stick’s centre is a processor and control panel, the brain of its operation.
Each LED corresponds to a pixel in an image, it can be 1 to 198 pixels tall, but thousands wide.
#PIXELSTICK PHOTOS FULL#
Pledging $300 will let you own the LED light bar. The Pixelstick is made up of 198 full colour RGB LEDs inside a lightweight aluminium extrusion case. Apart from that, the light bar is powered by 8 AA batteries.Īt present the team of Pixelstick is raising fund at Kickstarter. Moreover, Pixelstick reads images created in Photoshop so you easily create all kinds of light paintings. As we can see from the images, Pixelstick consists of two 3′ section of aluminum housing connected using a central bracket proving a mounting point for its handle, and the LED light bar totally contains 198 full color RGB LED lights, using a small mounted box the LED light bar reads images from an SD card and display them, one line at a time in order that you can use long exposure photography to take catchy light painting photos. Pixelstick is an innovative creative tool designed to offer you an easy way to take various amazing light painting photographs. Need a simple way to create awesome light painting photos? Take a look at Pixelstick, the LED light bar should be able to meet your requirements.
