VFD Clock Connects to the Internet


Here is, finally, one week later than planned, the sequel to my initial Ice Tube VFD clock .

It is able to :

  1. get the time from the internet and automatically synchronise itself (why have to set the time and use a battery to keep it running when disconnected, if we have Internet access ?)
  2. periodically fetch some weather data and display it
  3. do searches on Twitter and display the 1st result

So rather than “simply” displaying the time, every 15secs it alternates between the time, the weather and a Twitter message.

Twitter – PSP (java) – Arduino (Peggy2)


Pictures of the final installation, WORKING !

Final installation, on the kitchen table...

… so it all started, after I managed to make my Peggy2 LED board work, and I was wondering what to do with it…?

What else more obvious than display Twitter messages on it?

Now here’s the high level “design”:

– Peggy2 board with an Arduino microcontroller on it, should receive data serially, either over wire or IR

– how to get the data from the internet ? I don’t want to use a ethernet shield or wireless one, and it turns out I’ve been for so long annoyed that I have a PSP lying around and not being used… So let’s use it, it has wireless and can be programmed in Java (J2ME) be using the PSPKVM (greaaaat job guys !)

So there are 2 problems:

1) program the PSP to connect to the internet and download tweets from there

2) communicate between the PSP and the Arduino on Peggy

1) PSP to twitter.com
