      On August I was contacted by Ben from Seeed Studio to review the Fusion service. I received a coupon, which could be used only to order PCB.

      To define the Fusion service, I take this text from its website:

      Seeed Fusion Service offers one-stop prototyping services for PCB manufacture,PCB assembly and other electronic and mechanical customized services such as CNC Milling, 3D printing and PCB layout services.

      I didn't have at that time a design but I had something in mind that uses communication technology. I was experimenting using LoRa technology and I thought, I could managed to design a b...

      Happy New Year!

      This week has been a very busy one for me. But 2017 starts, and I have some new codes to publish!

      How I start? Ok, I've been working (may be playing) with Android Things using a Raspberry Pi v3, and I've been rewriting some of my libraries!.

      First, I thought, let's try SWIG and wrap the C/C++ codes to use them with Java. But, then I realized, that I needed a wrapper in wrapper, which I think is not possible (I am not an expert with these things, so if I am wrong, please leave a comment, I would appr...

      Hi everybody,

      I am back again! After almost a-two whole week(s) of code cleaning and updating I've just uploaded two 'new' libraries:

      CC++ RF24: https://goo.gl/3fTmlJ
      RF24Network: https://goo.gl/KONmkU

      These libraries are an extension to the great nrf24 libraries provided by TMRh20 and allow to connect the nRF24L01+ to the following TI-Launchpads:

      In the following days I am updating some example codes for CCS (Code Composer Studio) and EAGLE files.

      Stay tuned!!!

      I am calling this project DIVA (#ProjectDIVA), a...

      Hi everybody!

      I have just uploaded two repositories related to the EK-TM4C1294XL!

      You can:

      C Take photos over serial interface: https://goo.gl/8PlS7y
      Stream (slow) video via webserver: https://goo.gl/gQDFTO

      Connect the OmniVision ov7670 -old but everywhere- (version with FIFO AL422B) to the LaunchPad Tiva™ C Series EK-TM4C1294XL and take photos over serial interface, or use the http webserver to get a (slow) video streaming.
