<h3>LED-Goggles</h3> Video: https://youtu.be/fps8PyKuKQE Recently, I experimented with NEOpixels and one result are these mini goggles in a special style designed for my kids. The pixels rotate around the eyes and create a nice effect while the child can look through the goggles without any disturbance. The electronic is based on Arduino and the great adafruit neopixel library. There are more than 30 different programs of moving colored pixels that you can choose from. Two pushbuttons control the neopixel program, allowing you to scroll through the list forward and backward by pressing up and down. The included Arduino sketches are easy to expand if you're familiar with arduino programming, and I tried to comment the code as much as possible. In front of the goggles is a LDR that controls the brightness of the LEDs. If it's dark, the LEDs are darker; if it's bright, they're more brilliant. You can adjust this in the Arduino sketch as well. To hide the LED rings from the front, I used a paper ring laminated in transparent film (as filterscreen), giving a nice translucent effect. <h4>What you need</h4> 2 x Adafruit Neopixel rings with 16 Neopixels. I used standard types RGB SK6812 that fit exactly in part P3. I wired everything with wire-wrap wires in different colors. The controller is self-made (PCB-Files attached) and Arduino compatible, using a TQFP Mega328. To program it, you need an FTDI-breakout board connected via small wires and pin contacts. The arduino sketches are attached in the file section. As power supply, I used a small LiPo of 3.7 V that finds its place in the small electronic box as well.
