Microsoft just released its "Fall Creator's Update" with support for "Mixed Reality" - We take a first-look at Acer's headset, then Megan Morrone tries her hand at soldering when we assemble Skully v2!

Let's show off Microsoft Mixed Reality!

Acer AH101-D8EY Windows Mixed Reality Headset (w/2 wireless controllers)

• Same price as the Occulus Rift, but with better sensor tech & controllers
• Uses what they call "World Scale" VR/MR - It's what the rest of the industry call "inside out" tracking - That means there's no external hardware that you have to install
• Six degrees of freedom (Roll, Pitch, Yaw, forward/back, up/down, left/right)

Specs

• 1.35lbs
• 13 foot cable. (HDMI + USB 3.0)
• Dual 2.89" HINGED 2880 x 1440 LCD displays (90Hz refresh) (1,440 x 1,440 per eye) (706ppi)
• 100 degree Field of View * Proximity sensor, gyroscope, accelerometer, magnetometer
• Trackin Camera
• Bluetooth Sync
• Spatial Audio
• Motion Controllers

Acer Aspire 7

• 7th Gen Intel QUAD CORE i7-7700HQ * 8GB DDR4 (Expandable to 32GB)
• 256GB Intel PCIe SSD * 15.6" 1920 x 1080 LCD
• Nvidia GeForce GTX 1050 (2GB GDDR5)
• Gigabit Ethernet + 802.11ac
• 1 USB 3.0 + 2 USB 2.0
• HDMI * USB-C 3.1
• 3230mAh LiPoly Battery (7 hours)
• 5.29 lbs

The WS2812 Ring has 6 pads, we need three of them: GND, VCC, DIN

• GND to Arduino GND
• VCC to Arduino 5V
• DIN to Arduino Digital Pin 3

16 LED WS2812 5050 LED Ring

Arduino Nano

STL and Code

Let's put it all together!

1. LED ring is snapped onto LED shelf
2. Arduino is glued into the base caddy
3. LED shelf is screwed onto their mounting posts (2 screws)
4. Skully is attached to Deck (3 screws)
5. Deck is attached to base (2 screws)

Halloween isn't just for kids! It's the perfect holiday for makers and DIY'ers to show off their creativity! Megan and Padre stir up some Halloween delights from the dollar store, then jump into 3D design for an arduino-controlled Ghoulish delight!

"Project Skully"
Overview
We're fast-prototyping a Halloween decoration that uses IC-controlled LEDs and an Arduino to create an over-the-candy lighting effect.

Parts List
16 LED WS2812 5050 LED Ring
Arduino Nano
HC-SR04 Ultrasonic Module

Also Need
4 x M3 screws
30 AWG Silicone Wire

3D Parts

1. Skully_Skull
2. Skully_Deck
3. Skully_LEDShelf
4. Skully_Base

Original Skull by 3DWP

Here are the 3D Parts & the Code
https://www.dropbox.com/s/ti5vi23oxli3dtu/KH351_Skully.zip?dl=0

How do WS2812 LEDs work?

• You need three pins: GND, 5V (or 12V) and Data
• The data moves down the string of LEDs, each one takes three bytes from the array being passes (red, blue, green) and sends the remainder of the array down the string.

Let's put everything together!

1. Show the code
2. Open it up to show the connections

From the SR04

• GND to Arduino GND
• VCC to Arduino 5V
• Trigger to Arduino D7
• Echo to Arduino D8

From the WS2812

• GND to Arduino GND
• VCC to Arduino 5V
• DIN to Arduino D3
