Hi! My name is Nuno Santos and I’m an Electrotecnics and Computers Engineer. I live in Lisbon, Portugal and I work as a full stack developer in my daily job.

I created this blog to share what I’ve learned through my course, my professional life and my free time working with electronics, programming or learning about technology. I also have a YouTube Channel where I post some video tutorials.

  1. hi.
    did you ever try to use the Linkit 7688 Duo with arduino and REST API?
    To me it seams to lack that part on openwrt side.
    Im not able to make it work as my yun works…
    If you have. Pleas send me a note.

    1. Hi!

      Sorry never used Arduino on the Linkit :/ Just played a bit with Python at the time I was more actively working with it.

      It’s a very nice board nonetheless, very powerful and cheap, I hope to have some time to get back t it.

      Best regards,
      Nuno Santos

  2. Hi Nuno, I tried to leave a comment on one of your excellent blog entries but I don’t think it worked. If this comment works, I will leave more details here instead – hope you don’t mind.

  3. hi Nuno, fisrt of all thanks for your excellent Blog and useful tutorials. i had a problem with my project on ESP8266 that didn’t found any clear solution to solve it, could you please help me on that ?

    the issue is i want to config ESP as AP mode to route incoming ulrs to another one, for example:

    first run esp as AP mode, then i connect to it with my phone, and in my phone browser i enter this address “http://www.testwebsite.com/123,1234,12345” now i want to parse url and extract all numbers “123 1234 1234” then redirect/re-route to new url “http://www.newwebsite.com/123,1234,12345”

    for clear explanation.. you think i want to config my ESP like repeater, with manage on url.. the purpose of this project is, redirect all external urls to my local host web server “like xampp”

    could you please help me to handle this project ?

    thanks alot

    1. hi, Sorry for bothering you again 😀

      did you get the main purpose of the project ?
      i just wanna know is it possible to implement this project on ESP ?
      if it possible, could you please take some tips to do ?


      P.S: i searched for “captive portal” but i think it doesn’t help too much.

  4. i am facing issues with ds3231. I configured ds3231 with esp8266 as per your instructions. Initially it was fine after few days it is not giving the proper data. data is not incrementing. continuously i am getting 2000/1/1 0:0:0

    1. 1/1/2000 is the date of the clock after power up with no battery connected to the ds3231 battery pin so you have either no battery connected or the battery is flat so that the ds3231 always starts at 1/1/2000 at power up

  5. I just want to say a BIG BIG Thank you for your Blog! I just started learning to handle ESP32 and have to use it at work ( and play around with it) and your Blog is so much of a help with it!!!! Please continue doing what you do here!

    1. Hi!

      No, we are not related and I never met him 🙂 It is just a coincidence because Santos is a very common last name here in Portugal.

      But it is actually a funny coincidence that we are both from Portugal, write about the same topics and have the same last name!

      Best regards,
      Nuno Santos
