      Hi there!

      I've created a new 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 Google Cloud IoT PubSub topic.

      The new code can be found here:

      I've recently updated the nRF24Things project. 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 PiCoBo's) inside and outside of it, and the doors and window...

      Hi there!

      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.

      Hi everybody!

      I've recently updated the code for the communication between the raspberry pi v3 and the rf24l01+ module using android things (0.)4.1.

      You need the following things:

      You can find more info about the project on https://goo.gl/XsRJtI .

      I'm making a smart dehumidifier, so stay tuned more info is coming this week! (Update: here the link!)

      I've just uploaded the Java codes for the rf24, rf24Network and rf24Mesh that work with Android Things. This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi. I think this can also work with NXP Pico i.MX6UL and Intel® Edison with minor modifications (especially in the BoardDefaults file).

      In this post you will find some explanations about Android Things (installing, connecting, debugging, speed, etc.), the wiring of the complete 'thing' , the Java code, the mod...
