Nöbetçi Eczaneler on Google Maps

Nöbetçi eczane listesini google maps üzerinde göster.

For ideas (parsing a website etc.), see a website developed using Udacity's CS 253 course, KickSaver:
The backend is written in Python using the Google App Engine webapp2 framework. It uses BeautifulSoup to parse Kickstarter projects, and Tweepy to publish endangered projects to Twitter a few times each day. The frontend uses jQuery for asynchronous updates and CSS styles from Twitter Bootstrap.
See Udacity Showcase for more projects. A project using google maps api: Caravan Park Advisor

Update 28.01.2013: alpha version is live on appspot. Doesn't do much (just picks the first pharmacy from http://eos.aeo.org.tr/PublicSayfalar/NobetAra.aspx ) but I learned the following:
* Watched all unit of udacity's Web Development Course. Highly recommended...
* Using python to generate dynamic web pages
* Google app engine
* Google static maps (got the idea from Unit 5, starting with Geolocation)

Mute TV or change channel during adverts

Does the TV signal have a special code for commercials? Can we detect it?

Two alternatives:
1. (Easy) The TV volume jumps when adverts start. You can use that jump to identify a commercial started (see comment on Israeli paper below). False positive: An explosion in a movie.

2. (Hard) Write software that has a sound fingerprint database of the first couple of seconds of common commercials which it uses to send mute signals to tv to mute it for a typical advertisement duration.
* Catch probability > 90%
* Should be able to understand that a commercial started within 3 seconds

Arduino based solution:  http://blog.makezine.com/2011/08/16/enough-already-the-arduino-solution-to-overexposed-celebs/

In Ads, the audio typically pegs the meter, ofting a clear starting point in the 'muting' process. The cadence of the track itself will doubtless offer additional 'clues,' ie.: music/voice ratio, s/n ratio.

The processor must sample your (active) program material periodically, and record a set of average levels. These are then compared to the (new) offending audio track. When the original track returns, it auto restores the signal. This process is so simple that it could easily be incorporated into every new digital TV.

Insect detector

* Detection:
** Distance sensor: Is it precise enough for insect size/motion (esp. the small silver bug)?
** Trap with infrared LED+photo transistor: When insect passes through tube, detection should happen. Is LED+transistor precise enough for insect sized objects?
** Image processing?
