Mainedrian - Fall 2013

A visualization of Maine population data in the style of Piet Mondrian.

I've been working my way through the Raspberry Pi series Baking Pi, tutorials for writing ARM assembly on the Pi. I've finally progressed to putting graphics on screen. #leveledup

Getting much closer to putting the Pi in Pintos.

I've been working my way through the Baking Pi tutorials for the Raspberry PI. Finally doing something other than blinking an LED on and off is much more rewarding and cooler to share with others.

As holidays approach, think about reverse engineering those Christmas toys.

Wanted to share this kickstarter with folks, I imagine people in this group might be interested in a microcontroller built around Python.

You can write simple programs like

while True:
    pyb.led(True)
    pyb.delay(1000)
    pyb.led(False)
    pyb.delay(1000)

to blink the LED.  

Seems like a great board for getting into hardware.

Any Hack Portland folks headed up to Pycon?

More assembly programming based on the Baking PI series. Tonight implemented a drawing library and a pseudo random number generator.

It is a bit hard to see in these photos, but the pi is rapidly drawing lines of different colors in random places on the screen much like a screen saver. 

Next up, putting actual text on the screen.

The line drawing is a pretty neat algorithm, Bresenham's Algorithm, because it can be done with add, sub, and left shifts.

Anyone want an invite to the atom text editor?

Sent. Not sure if yours went through, Michael... so hopefully Sam can help you out if it didn't. Also, probably can just sign up the way I did on the home page.

Definitely a beta product, but I like it so far.

This is the kind of product I imagine could be designed and built at a Portland maker space. A small scale, niche, and well designed product would be a good fit for this town.

What do you all think?

Totally!  If you were to give everyone a class or two in DIY electronics and rapid prototyping I think you would see a lot of novel re-thinking of everyday items.  Most people don't yet know what's possible.

Another great kickstarter for hobbyist computing  -- introducing Kano: A Computer Anyone Can Make.

If you've been thinking about getting a Raspberry PI, this seems like a great way to get started.
