Sci Fi Your Pi: PiDesk - Project Update #10

Project Update

Project Update #10 already and only one week away from the challenge's halfway point. Time to kick things in a higher gear. That's why I've done something slightly more technical for this week's update: I've created my own capacitive touch breakout board!

 

As you may have seen over the course of the project, I've been using the Touch Board as a capacitive touch input sensor for the Raspberry Pi. I used it because I had one and thought it was the perfect opportunity to use it, since I never had (like many other boards I own ...). Unfortunately, for others trying to recreate (parts of) this project, it is an expensive investment at about €76 (post-kickstarter). That's why I set on a quest to reduce the cost of that component and ended up succeeding with a cost reduction in the range of 95%!

 

I've used the Atmel AT42QT1070 touch sensor ICAtmel AT42QT1070 touch sensor IC on a custom-made breakout board to convert up to five of the Pi's GPIO pins into capacitive touch inputs. The cool thing about this little breakout board is that it could be used in combination with other SBCs or microcontroller boards! The board was designed in Eagle and produced via SeeedStudio for €10 including shipping, for 10 boards (I did receive 20 though ...).

  • Hi Frederick,

     

    Project Update #10 already and only one week away from the challenge's halfway point.


    Halfway point? What do you intend ?

    Next week is week 9 of the challenge, out of 18 weeks. So halfway point image

    Your answer is what I supposed to be image So, just as what I though initially the Challenge will end in next 9 weeks., if I am not wrong. But I have read - about the week after the challenge officially started - discordance in the ending date in different parts of the E14 site. So I asked for details to writing this email on last May 12

     

    1: it is the challenge reference that will be judged at the end of the challenge or it is expected that before the end I do something else too?

     

    2: In the last documents on the SciFi I have read that it ends on the end of July, somewhere else (the press document) that it finishes in September and on the application rules I have read that all should be sent not later than the midnight of August 25. What is the real deadline ?

     

    And the same day he answered me the following:

     

    Enrico, I have updated the documents.

    To clarify, final entries must be received by July 20th

    We will announce the winners the first week of August.

    So as far as I know, only 4,5 week remains to the end. I had to change the project timeline plans when I had this news. What do you think about ?
