Hackster, YouTube Channel and Safe UsbKey Project

Hi,
 if you are a reader of this blog.. I'm still alive :)

I've built in the last year, a lot of project (#alexa, #arduino mkr1000, #arduino 101, #linkit smart etc), you can find on my hackster page: https://www.hackster.io/crazycoder1999/

I'm starting to make some video on my YouTube Channel .

Right now, I have a side project called Safe UsbKey Project : here is the playlist of the first videos.
I will stream live today a new episode on how to create a build environment for the board.

The idea of Safe UsbKey Project is to build a sort of filter/proxy between computer and usb key in order to protect computers against viruses and other attacks.
The project use the arietta g25 from acmesystems.it.

Tethering Indicator: start simple grow complex

I'm back from holidays... but during it, I did something on my tethering indicator project.
It was thinked as a simple application.. and now it is no-more a pure simple activity that talks with bluetooth..but something more complex.

The apps on the phone, is composed by 2 part:
- a service that make available data through bluetooth and show a notification whenever it is started.
- an activity that talks to the previous service for control and send command like: start/stop service.
It was not easy to understand how to make the activity bind and unbind correctly from the service, also when the activity die,  but after some test and research I did it.

This is a simplified diagram of the actual architecture :

I didn't released the code now, but I will do very soon, at least for the android server, when it will be enough good.
For now the program on the phone works.

A new project: a Tethering Indicator

Scenario
I usually take a train in the weekend and travel for 150 km with my Macbook or Tablet connected to my Android phone in tethering mode by bluetooth or wifi.
While I travel by the train, my phone is usually inside my bag and I only have in front of me the Macbook...  I check only sometimes the phone but it is mainly inside my bag.
During my travel the phone connection change a lot and pass in one of this state: no connection, only phone network, 2G or 3G.
What I'm searching to create is an app on the phone that talk with my macbook and regularly send information of the network state of the phone.


How should it work?
These are the step that I have in mind:

• I launch the apps on the phone and start the bluetooth server
• I launch the application on the mac
• I establish from the mac the connection with the phone
• On the Mac menubar, an Icon display the state of the phone's connection.

This is the basic idea.. but I have some new improvements in mind.

What have I done till now?
The first version of the mac client is in "under construction" state..  The application is capable to connect to the phone but I don't know, for now, how to put and change an icon on the menu bar for the various phone connection state... Need to go deep about it.

Android side is in progres: it is capable to create a bluetooth server and send informations to the connected client back...
Something on the android client will be visible tomorrow soon.

Other platform?
Of Course!
stay tuned.
