I finally got time to hack together the prototype for the class project for my class this weekend. We’re going to be using the RaspberryPi to connect to Plivo and make phone calls, nominally to our Mom’s. I thought one button was boring so our call Mom Button class will actually have 4 buttons suggested as:
* Call Mom
* Call Dad
* Text Mom “I love you”
* Mother’s day special
For more details or to sign up see Meetup.

Next Saturday I’ll be teaching another class at my hackerspace, the MakerBar in Hoboken. This will be my third Raspberry Python class. Following up on the initial class, and the train class. Like the others, this workshop will cover the basic use of a Raspberry Pi, but it’s coming together really well, I’ve got a Pi sitting on my desk chattering inane things from my twitter feed at me and actually, it’s proving more useful than I expected. Just in developing the project I’m finding more out about my friends than I had before–mostly some corporate feeds to unfriend and some friends to check up on.
The class will run about 2-3 hours so we’ll have time to get our Pis setup, on the latest version of Raspbian, which already includes NTP, and really dive into the programming and improvement. Since most of our time and effort will be software, the hardware is perhaps not so impressive, no loop of train track here, but this is a picture, of the prototype
If you’re interested in coming, please rsvp at meetup here. And if you need a Pi or SD card, leave a comment there, a few are on order so we should have some.

By the end of the week it will be February and my hackerspace, MakerBar, will be on to our February theme, it’s about time. The members are talking about clock and calendar projects and there are two clock classes in the works; Raspberry Python – Talking Clock Feb 9th and ChipKIT for Organic Lifeforms: Clock Edition Feb 23th.
This then is the first clock of February, a ChipKIT Uno32 with a ChipKIT Basic I/O Shield attached. As befits a beginning this is a very simple project.
Step 1 Solder in RTC Crystal (based on instructions here)
Step 2 Attached Basic I/O Shield (got this for contest here)
// Initialize the RTCC module
// Set the time to something sensible
// Format the time and print it.
sprintf(date,”%02d/%02d/%02d”, RTCC.day(), RTCC.month(), RTCC.year());
sprintf(time,”%02d:%02d:%02d”, RTCC.hours(), RTCC.minutes(), RTCC.seconds());
//Clear the virtual buffer
//Chosing Fill pattern 0
//Turn automatic updating off
This clock will become the basis of the class project for the February 23th class, ChipKIT for Organic Lifeforms: Clock Edition. The clock in that class will not rely on this shield and will have functionality this clock does not, like setting the time, and time permitting an alarm.
