Getting Started With Windows IoT Core on Raspberry Pi
How we got up to speed!
by Rick Lesniak
There are lots of resources and tutorials on the web for getting started with Windows 10 IoT Core. But we thought it would be useful to document the process we went through to get up to speed with Win IoT on the Raspberry Pi.

Fake TV Light for Engineers
When fake "FakeTV" is too fake
by Phillip Burgess
Sometimes simple ideas get hung up on the most persnickety details. This NeoPixel project makes a window look like someone’s home watching “Wreck-It Ralph.”
Windows Tools for the Electrical Engineer
Do the best with what you've got
by lady ada
You're an electrical engineer. And you have to run Windows - because a vast number of utilities and eval tools are Windows only! Or perhaps you're running windows out of choice. No biggie, either way you can make your environment pretty flexible with some tools.

Programming Microcontrollers using OpenOCD on a Raspberry Pi
Native GPIO bit twiddling your way to success
by lady ada
OpenOCD is great because its cross platform, open source, and has support for a vast number of chips & programmers. You can use OpenOCD with dongle-programmers such as J-Link and ST-Link or even an FTDI chip. But, if you have a spare Raspberry Pi (and who doesn't these days?) you can use it as a native OpenOCD programmer with just a few wires.
Arduino Package Tracker
Have your Arduino tell you when your packages arrive.
by Vaughn Shinall
This guide will show you how to build an Arduino package tracker that will alert you when an anticipated package arrives at your door. Using an internet-connected Arduino, a proximity sensor, and Temboo, we’ll build a device that connects hardware to web services in order to track packages and notify you when they arrive.
Supernova Poi
They'll be able to see you spinning from Planet 9

These prodigious POV poi pack a pretty punch. Super fast and super high resolution Dotstar LEDs a giant 2200mAh battery, easy control with an infrared sensor and remote, and a galactic amount of memory so you can upload hundreds of images and spin all night.
Atmega32u4 Breakout
8 bits + USB = <3
by lady ada
We like the AVR 8-bit family and were excited to see Atmel upgrade the series with a USB core. Having USB built in allows the chip to act like any USB device. For example, we can program the chip to 'pretend' it's a USB joystick, or a keyboard, or a flash drive! Another nice bonus of having USB built in is that instead of having an FTDI chip or cable (like an Arduino), we can emulate the serial port directly in the chip. This costs some Flash space and RAM space but that's the trade-off.
LIGHTSHIP: LED Animation over WiFi
