A spherical Persistence Of Vision device using WiFi and BLE #POC #WiFi #Bluetooth #NeoPixel #DotStar @H0meMadeGarbage
Via Home Made Garage comes a spinning persistence of vision (POV) display. Using multicolored addressable NeoPixel or higher refresh DotStar LEDs, the device uses WiFi and Bluetooth to receive commands.
This road is going to make a spherical POV (Persistence Of Vision) device using wifi and BLE. Up until the last time, we were able to confirm the operation related to wireless, so from here it is finally assembled for POV!
This time, we compared how much afterimages can be seen by actually rotating two types of LED tapes.
Dotstar has a very high refresh rate and is suitable for POV. However, it is difficult to obtain in Japan and is expensive (mainly shipping costs …), so I compared the operation with the popular Neopixel to see how profitable it is.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
