Uploading Arduino Sketches to the Teensy 3.1 from the Terminal

First, install Arduino 1.6.1 from http://arduino.cc/en/Main/Software. I followed the Mac OS X for Java 6 link to download arduino-1.6.1-macosx.zip. Install Arduino by unzipping the Arduino file and moving it to /Applications/Arduino. Open Arduino to make sure it works and so it can finish setting up the environment for use. Next, install Teensyduino 1.21 from https://www.pjrc.com/teensy/td_download.html. I followed Macintosh OS-X Installer to download teensyduino.dmg. Open and proceed through the Teensyduino installer, and when prompted to locate Arduino, select /Applications/Arduino, then continue to the next step in the installer.

At this point, you should be ready to upload a sketch. Follow the instructions below.

To upload from the terminal, enter the following command:

/Applications/Arduino.app/Contents/MacOS/JavaApplicationStub --board teensy:avr:teensy31 --port /dev/tty.usbmodem573061 --upload /Users/mokogobo/Checkout

1. compile ffmpeg for arm https://github.com/fiorix/ffmpeg-arm
2. create youtube 'live event'. get rtmp url + session id
3. run this:

raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/<SESSION>

you can tweak -b and -fps to your liking. the settings above work well for 1080p. by not specifying width or height we get the full 1920x1080 resolution from the raspi camera

Flask + uWSGI + nginx Primer

I've been having trouble with serving a Flask app via uWSGI and nginx, so I thought I'd put together some of the basics to help out others.

How this shit works

• Flask is managed by uWSGI.
• uWSGI talks to nginx.

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.
