After upgrading my Galaxy Note 3 to Lollipop, I ended up losing my root access. That just won’t do, so it’s time to cover rooting the Galaxy Note 3!
What Is Rooting?
Root itself is a user account within Linux that has elevated permissions. It’s similar to an Administrator account when working with Windows. A root account has permissions to read/write/execute any file on the Linux/Android platform and is often required to run any sort of custom rom on the device. The process of gaining access to this account is called “Rooting”
For a while now Kevin B has been working on writing a library for communication using the NRF24l01 radio with the Arduino’s. The idea is to use them for home automation purposes. But of course that’s only one piece of the puzzle… what good is home automation unless it’s also internet ready?
I took it upon myself to start looking into that portion, since it’s right up my alley (between server-side scripting such as PHP along with a database such as MySQL, and the API needing to working with Android of course).
Over the weekend I decided to pull out some of my cheap strip LEDs and put them to good use with a little bias lighting!
What is bias lighting?
Don’t feel bad, up until a few days ago I hadn’t heard of it either! Bias lighting is the effect that can be achieved by placing a light source behind your television. Surprisingly, this has been around for a very long time but is only now becoming more main stream with things like the Phillips Ambilight+Hue system, as well as more and more manufactures placing some form of lighting directly in the rear casing of TVs. But there’s no need to buy a $2000 TV just for some lights (average price of an Ambilight TV at time of writing).
A while back I made a trade with a co-worker for an old netbook in exchange for a Raspberry Pi Model B+. In case you haven’t heard of the Raspberry Pi (…what rock have you been hiding under!?!), its a small credit-card sized computer, originally designed as a low cost and low power solution for schools to teach kids more about programming in languages such as Python. But because of its small platform and low cost, it quickly became very popular in the hacker community as well. My Raspberry Pi has just been sitting on the shelf for a little while now, I figured it was time to blow off the dust and power it up.
I have a co-worker that picked up an old DSC PC5010 alarm panel (for free, you can’t go wrong right…) and since I had fun writing about the Honeywell Lynx Touch Backdoor, I figured I’d give this a go and see what happens. The problem… the panel had installer lockout enabled.
You can tell when a panel has installer lockout enabled because you will hear a distinct 8-10 clicks from a relay when the panel is initially powered up (see video directly below). When the panel is locked out like that it blocks the ability to default the panel back to factory (even by hard wire reset), so unless you have the installer code, you’re SOL…
