At the beginning of October I wrote a blog article called White Hacking: WeMos and SquirelCrawl!. I used the WeMos (ESP32) and the firmware provided by Hacker Arsenal to do a captive portal. As you known, a captive portal is a web page which is displayed to newly connected users before they are granted broader access to network resources [wiki]. This can be used in combination with evil portals to obtain login credentials. The firmware provided by Hacker Arsenal has mul...

And once again! Word files with Macro! But this time, I was the first one to report it to VirusTotal and Hybrid-Analysis! :)

I was surfing the services that Google offers, I found the Geolocation API. As Google describes the API: it returns a location and accuracy radius based on information about cell towers and WiFi nodes that the mobile client can detect. As I was writing the last post using MicroPython, I thought the WiPy 2.0/3.0 could be a nice "mobile client".
To use the API you need to get an API key from Google. As a standard user of the API, you get:
- 2,500 free requests per day, and
- 50 r...
I don’t have any Belkin WeMo system or Philips Hue light bulbs. However, I have two ESP32 running MicroPython (see my last article), and a W2812b LED strip, and I thought I should be able to say, "Echo/Alexa, turn on the kitchen light" or "Echo/Alexa, turn on the blue light" and It should work with this setup.
And... it works as you can see in this video!
If you are interesting in only using the code, then click here. Otherwise, you can read the complete story... ;)

Another quick tutorial, this time for MicroPython on ESP32/ESP8266. You can find all the information that I'm writing in this post in different articles on the Internet but I've not found anything that summarizes all the topics. That is why I am writting this article. I included some links at the end of each topic to extend the info. Feel free to visit them, if you want more information, or write a comment I will try to reply it ASAP!

I was surfing the web for new hacking software and hardware tools and I found the Hacker Arsenal website. This website offers "ARTILLERY FOR CYBER WARRIORS" as they said; it is basically hardware and firmware for pentester. In summary, they have actually three products especially for Wi-Fi Sniffing.
I found the
Winx-Portable(update 17.10.2017: they are not offering this product anymore, they are offering the WiNX) on the website and I thought ... This article is outdated! I wrote the following new articles:
- #ProjectDIVA: Android Things 0.8.1 getting started!
- #ProjectDIVA: Android Things v1.0!
As the title says, this is a getting started with Android Things. It should be my first post, but, it's better now than never. I'm posting this to summarize the steps to install Android Things on your Raspberry Pi.
Some parts of this article maybe outdated! I wrote the following new article:
ProjectDIVA: Android Things 0.8.1 getting started!
Google announced Android Things on December of 2016. It's a modified version of the Android that we all know, but for Internet of Things (IoT) devices. The architecture of the SDK is described in the following figure:

Yesterday I received an email from an address that should look like my boss email address. It was something like this: "Boss.Name@our-institute.uni-hannover.de email@example.com" with the subject:

Android Things DP5.1 is out! and the bugs were fixed!!! You can check the release notes here!.
You don't need to change the
config.txtfor the display settings and the debugger issues were solved and it is working again (tested! - it stops at the breakpoints)!
You can download the zipped image using the Android Things Console! Check this post for more information!
There are some problems with my two Android Things repositories and the applications are not working as expected :( but I will be updating the GitHub repositories this weekend!
Stay tuned! and have a nice friday!

Android Things DP5 is out and of course, new features are available.
The most important features are:
- Runtime Pin Configuration
- OpenGL 2.0 Support (that means hardware acceleration on the RPI!)
This time you need to use the Android Things Console to download the image as follows:
- Go to: Android Things Console and sign in using your Google credentials
- Click on: Create a new Product
- Go to: Factory Image
- Select: Empty Bundle (if you don't have any app) and the Android Things v. OIR1.170720.015
- Click on: Create Build Configuration
- Make a coffee or just wait a coupl...

Two posts in one day! Now the SensorTag CC2650 is running on Android Things. The Raspberry Pi 3 can be used as a sensor hub, and the SensorTag can be connected to it using BLE. I modified the original app and now it is working on Android Things! Minimal changes were required, especially on the files related with the user interface. Moreover,
WebViewis still not supported on Android Things.
The code can be found here:

I've uploaded a repository for the Texas Instrument SensorTag CC2650. I updated the open source TI repository, which can be found here.
Due to licensing restrictions (I do not know which ones) Texas Instruments was no longer able to keep the open source code in sync with the SensorTag application in Google Play. That means, the new version in Google Play has more features than this one. But this is open source, and can be modified and extended! I am planning to collect the sensor data and publish on a G...

I've recently updated the
nRF24Thingsproject. I introduced some changes to the database main table (
sensors) and to the handler class
DatabaseHandler. Additionally, I added a second table for the payloads (
payload). The two tables are related using the foreign key
nodeID. I added some search options for the payloads: search by payloadID, nodeID etc.
The main idea of this project is to measure the humidity, temperature, air quality etc. of a room with multiple sensors (may be using the Pi...

I had some humidity problems in the basement and I thought I can buy a dehumidifier. I bought this one on banggood Dehumidifier 500ml. I knew they are not good enough, but I wanted to try.
This type of dehumidifier uses a peltier element to cool an alumium disipator (peltier cool side), which condenses the humidity. The condensed humidity drips into a water tank until it is full. Then, a switch is triggered and the system stops. The peltier hot side has a bigger disipator and together with a fan disipate the generated heat.
