Magnetic QI charging phone mount for the car

What is my current setup?

For the past year or so I've used a Homespot NFC enabled Bluetooth audio adapter to stream music from my phone through the 3.5mm aux port in my car. Meanwhile my phone has been attached to the air vents with a Tetrax Geo magnetic mount. This is used with my Samsung Galaxy S5.

If you have a Nexus 5, this will work even better.

While it's been pretty good, there have been a few flaws:

  • The Tetrax mount requires an unsightly metal button to be stuck on the back of your phone though otherwise works fantastically!
  • The Homespot NFC audio adapter needs to be tapped with your phone each time you get into the car, pretty annoying.
  • The charger for the NFC audio adapter is quite large and takes up the cigarette port, meaning you can't charge the phone at the same time.

What's the plan then?

This is how I intend to improve my setup:

Raspberry Pi as an SMS Gateway

Today was one of those days where I thought I'd find something useful for my Raspberry Pi to do, rather than sit in a box unloved.

I was thinking how we send a lot of monitoring notifications as emails and how bad email is as a single method notification, especially if what you are monitoring is your connection to the internet... Internet connection goes down, how do you send the notification out?

I had a 3G USB dongle also sitting around doing nothing, so as a test I stuck a Pay+Go simcard in, made sure it had some credit and connected it to my Raspberry Pi.

This is how I got it to send an SMS (Will likely expand this post as I add features).
