Apple’s airplay system is great for streaming music around the house to big speakers, but expensive because you need to buy their Airport Express Router or an AppleTV to make use of it. Those devices are great, but they offer a lot more functionality that what I need. I just need an access point to be able to send music to my speakers. Most of my systems are not connected to TV’s and I’ve got a very powerful router already. So this is what I’ve landed on. This project is one I’ve been working on for a while now, trying …

Today’s project is a simple one. A basic introduction to both FreeCAD and QR codes. You’ve probably seen QR codes around, posted on the wall, online, or on the product manual of some device you bought. They can be used for a tremendous number of things and are essentially an easy gateway to download an app, navigate to a website, or give out your phone number.

So below I’m going to link to PCPartPicker, a great site that helps …
