The Hackable Clock ================== A hackable alarm clock, made for experimentation in order to build programming skills as well as the basics of circuit building. Lessons and tutorials are currently a work-in-progress, however drafts are available at http://hackclock.deckerego.net/ Building the Hardware --------------------- Step-by-step instructions for creating your clock are available at https://hackaday.io/project/3413/instructions A suggested list of hardware you might need to buy is saved as a wishlist at Adafruit: https://www.adafruit.com/wishlists/413935 Usage ----- Once the app starts, you should be able to get to the clock's web interface on port 9003. For example - http://raspberrypi:9003/ Audio files and user-created source code is saved within the `/home/pi/hack-clock` directory - so it should be easily accessible for the pi user. This can be changed in `/etc/hack-clock.conf`. Source is backed up each time the user saves - so if you accidentally screw something up it is quick to recover. Clicking the "restore" button also opens up the source code for each lesson provided at http://hackclock.deckerego.net/. If you restore a lesson, you can find some good starting points and suggestions for your clock. Installation ============ I'm assuming that you are starting with the Raspian Minimal Linux distribution available at https://www.raspberrypi.org/downloads/raspbian/ or pre-installed by several distributors. NOOBS or the like also works, but Raspian Minimal is small enough to fit on a 2GB microSD card. To install the hack-clock distribution on top of Raspian: 1. Make sure your Raspberry Pi is up to date with the latest packages & firmware with `sudo apt-get update; sudo apt-get dist-upgrade` 2. Enable I2C by executing `sudo raspi-config` as described in Adafruit's tutorial: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c 3. Add the necessary Python and GStreamer dependencies using the command: `sudo apt-get install wiringpi ntp python-bottle python-requests python-oauth2client python-httplib2 python-setuptools python-pip python-dev python-dateutil python-smbus gstreamer0.10-x gstreamer0.10-alsa gstreamer-tools gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly python-gst0.10` 4. Install hack-clock via `wget https://github.com/deckerego/hack-clock/releases/download/2.3.1/python-hackclock_2.3.1-1_all.deb; sudo dpkg -i python-hackclock_2.3.1-1_all.deb` 5. Tweak `/etc/hack-clock.conf` and `/etc/default/hack-clock` to fit your needs (GPIO pins, correct weather station, etc.). A list of observed weather stations is available at http://forecast.weather.gov/stations.php 6. Reboot your Pi to re-load modules and start the IDE web server Upgrading from 2.x ------------------ Upgrading from another 2.x release is pretty easy. Just execute `wget https://github.com/deckerego/hack-clock/releases/download/2.3.1/python-hackclock_2.3.1-1_all.deb; sudo dpkg -i python-hackclock_2.3.1-1_all.deb` and reboot your clock! Upgrading from 1.0 ------------------ Earlier versions of Hack Clock installed the entire application in the user's home directory, however starting with version 2.0 we are only installing lessons, audio, and the current running code in the home directory. If you are upgrading from an earlier version of Hack Clock, first make sure you back up your earlier installation by copying your current Hack Clock directory, as in: cp hack-clock hack-clock_old After installation, copy the `blocks_clock.xml`, `run_clock.py`, and any audio files over to the new `hack-clock` directory within your own home directory. The older version of Hack Clock also used the headphone jack instead of the I2S interface. If you would like to continue to use the headphone jack, modify `/boot/config.txt` by commenting out the I2S interfaces and un-commenting the `audio=on` parameter. For example: # Enable audio (loads snd_bcm2835) dtparam=audio=on #dtoverlay=hifiberry-dac #dtoverlay=i2s-mmap Once you have commented out the I2S settings as shown above, subsequent upgrades should just skip the I2S changes so you don't need to keep re-commenting things out. You will also need to remove the custom `/etc/asound.conf` configuration file on your Pi - it does not need to be present if you are using the headphone jack. Coding With Blocks! =================== Coding by Blocks is now the default way of programming the Hack Clock! If you would like to revert back to Python, change the following entry in `webapp/config.py`: 'default_editor': '/python/edit' If you would like to add a button that allows you to switch between Python and blocks editing, change the following in `webapp/config.py`: 'disable_editor_button': False Note that if you save a set of blocks, it will overwrite any Python coding you have performed. Likewise, if you make any Python edits it will overwrite whatever code was generated out of Blockly. You can still restore from previous Python or Blockly save points however. Known Issues ============ The Google Music API (gmusicapi) requires lxml, which often requires native compilation for ARM. Compiling lxml can take over 500M of RAM, which some smaller Raspberry Pi's don't have. To work around this, you can increase the swap file size of your Pi by editing `/etc/dphys-swapfile` and setting the swapfile value to: CONF_SWAPSIZE=512 After setting this value, you can have them take effect by restarting swap: sudo service dphys-swapfile stop sudo service dphys-swapfile start Bear in mind that swap is *slow*, so the build will likely take a while.
