Today I will tell you about a new project. POV Globe. Persistence of vision. A quick intro to POV or persistence of vision: Any AC voltage light is actually blinking on and off at a frequency of 60hz or 60 times per second. Our brains perceive this as constant light. It is this concept which we will be taking advantage of, in order to create a spherical image using a single row of LEDs. We used 58 led for each half. So you need totaly 116 leds. And will use a 3D printer for circle. You will find details on video.
Step 1: Equipments
This project has some materials as electronic and 3d parts.
- Arduino Mega
- WS2822 Adressable Led
- Proximity Sensor
- 608zz Bearings
- DC Motor
- 3D Parts
Step 2: LED Strip Assembly
We assemble led connections. We have two part led strip. All 5 V ,GND and DATAs will be together. You will see details on pic.
Step 3: 3D Parts Assemble
And now assembling 3D parts. Our circle made of 4 quarters parts. So you can see in pics. a half of circle has a 58 Leds as right and left.
And we use a system non cable for power. AS you can see in last pics, We are touch with a metal parts to power.
Step 4: Wood Supporting Assemple
as you can see we built a support with woods.
we continue to built supporting. Firstly we assemble power parts. and than DC motor connection.
Step 6: Let's Play
