Machining PLA from my RepRap

I've got a Taz 2.1 from Lulzbot. It's tons of fun, but I had really hoped I'd find some joy in the ability to use it for rapid prototyping. I've done some minor stuff with it, but this weekend I finally got to build a thing which I designed that was not trivial.

Wake Me Up!

Alarms are alarming. They’re super fine and useful if you really need to be up at a certain time and it’s hard for you to hit it. Otherwise, they are the harbingers of morning terrorism.

Philips Hue API Hacking

Here it is! My Python client for the Philips Hue system is done.

The Short:

It's available on Github.

Sample Usage:

from hue import Hue
h = Hue() # Initialize the class
h.station_ip = "192.168.1.222" # your base station IP
h.get_state() # Authenticate, bootstrap your lighting system
# The first time, you have a minute between calling get_state() and pushing
# the button on your base station to authenticate your machine. It should
# Log and tell you if that is going to happen or not.
l = h.lights.get('l3') # get bulb #3
l.bri(0) # Dimmest
l.bri(255) # Brightest ...

I'm Issac Kelly. I like to build things, with software and hardware. By day I do that at Nonchalance in San Francisco. I like to teach people, but mostly about the things I'm interested in. I'm currently a mentor at Hackbright Academy. I'm building open source automation, albeit slowly at Plum Garage.
