Microsoft Surface Pro 3 – IMPRESSIVE!

OK, Microsoft!  You’ve got my attention!  I have to admit, I used to be a MSFT fanboy, especially because the development tools they offered were the best around at the time.  Back in 2005, I even attempted to build my home automation system using .NET and Flash and built in-wall touch screen (DIY: Inwall 15″ LCD touchscreen).  I had Window’s CE phones (the first “smartphone”), HD-DVD (yup, I supported that), Viewsonic Smart Displays (remember those?), I use Microsoft Media Center with Extenders (MSFT abandoned it).  See, the problem is that MSFT has not stuck through with the great technologies it has created — they release something and right when you think it’s going to go mainstream, they back out and kill it.   I made the switch to Apple’s ecosystem once the iPhone came out and learned to develop in Objective-C.  I’d rather invest in technology that improves (slowly) overtime than ones that come out strong and then nothing comes of it (dies a slow death).

(This is part of a multi-part series on building a FPV mini 220mm 240mm quadcopter)

I've been looking at different frames for the quad I'm building.  The proven 220mm "H-Quad" style frame by Blackout (known as the Blackout Mini H Quad Frame w/ Power Distribution Board) is highly respected and top on my list.   However, many of those have already been built and you can find many awesome videos on YouTube showing it's capabilities.   Steve sent me a forum post at RCGroups.com about a new 240mm folding mini H quad frame by Bay Area Heli called the Nemesis 240mm Mini folding FPV Quad.   It comes in either G10 and Carbon Fiber material.

DIY: Building a Mini (220mm) Quadcopter Part 6 – 12V Step-up Voltage Regulator

The last part ordered was the FPV Camera and that operates at a voltage of 12v.  Since I will have a clean 5v provided from the video transmitter (to be selected later), I need a 12V step-up voltage regulator.

The Omni Notifier, Sends Email and Text Messages From Omni Panels

omni-notifier Leviton Security & Automation (formerly HAI) has released a new module that brings email and text notifications to any Omni (Pro II, IIe, LTe) or Lumina (both) control system.  It uses one of the RS-232 ports on the controller and needs an ethernet connection (in addition to the one that is probably already connected to the Omni panel) -- the best part -- it requires no service contracts to use!

DIY: Building a Mini (220mm) Quadcopter Part 5 – FPV Camera

What makes the quadcopter I'm building different than say a DJI Phantom?  Well, the main difference is that I'm building a FPV (the First Person View) quadcopter and to achieve the FPV part you need at least one camera (I'll be installing two, one for the FPV and the other to record HD video -- more on that in a later post).   The FPV camera broadcasts via a transmitter (will be selected in another post) to the ground station which can either be a simple video display with a wireless receiver or video based goggles (also to be selected in a future post).

The video from the front mounted camera is what you will use to fly (or steer) the quad in the air without needing line of sight view -- you see what the copter is seeing.  The video signal also has superimposed telemetry data (via the OSD module).  As this is technically the "eyes" of the copter it's important to have a high quality camera that has a high dynamic range and provides clear sky and ground exposure.

DIY: Building a Mini (220mm) Quadcopter Part 4 – The Battery

You need batteries to fly a quadcopter.  The battery we selected will be used to power the receiver, flight controller, the OSD, FPV video camera/transmitter and to power the four motors that spin the propellers and give the quadcopter the lift it needs.   As you can see, the battery is very important and also adds the most weight per single item.   We've selected the Turnigy nano-tech 1500mah 3S 35~70C Lipo Pack to power our copter.
