The 3-axis accelerometer measures the changes of speed. This information can be used to deduce the alteration of positions.
This is a breakout board for Freescale’s triple-axis MMA7260QT accelerometer. With a low power shut-down mode, high sensitivity output with selectable ranges (±1.5, 2, 4, and 6g), this was one of the very first sensors to market with three accelerometers built onto a single IC! Board comes fully assembled and tested with external filters installed.
The MMA7260QT is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). You will need some extra hardware to convert this analog signal to a usable digital one. Luckily, many uCs have a built in Analog to Digital converter.

You want to use a SMT component but are really bad at soldering? So here you go! Just push the component in the socket and use the easy accessible breakout pins.

This 18W mono amplifier works with 6V to 12V, so its the perfect candidate for a portable speaker.

Turn any input voltage between 7 and 36 Volts into 5V output voltage (current limit: 1,5A)
When used in higher current (>0,5A) applications, a heatsink should be applied. -

The [Physical Computing Library] is an physical library for electronical components which every student of the program can rent.
If you have questions contact Physical Computing Library.
-
Currently Physical Computing Library is responsible for the
[PCL].Each component has a button called
rentwhich creates an email you then only need to send.
-
The easiest way to operate the library is to use github.
In the web-interface you can create files and folders and change their contents.If you want to use the library offline on your own computer thats not a problem either. (have a look at the contribution section)
Lend a component to someone
Every component has a
lent-folder in its root directory. These folders are special as every file in it is interpreted as a person currently lending the physical component. Usually these file-names should be named after the person who is lending and contain some extra information in it, but this is just a convention and can be done differently.Here is an example of such a "lent-file":
// filename: component/lent/studentname.md email: ab@c.de // a way to contact that person ---- date: 20.1.2017 // a date when the component got handed outJust delete the lent-file if the component is not lent anymore.
Change the availability
Every component has a markdown-file in its root-folder that is called
component.md.
In this file everything about the component itself is stored. There is one parameter which is calledavailablewhich controls how many of a kind of a component the pcl owns. If a component is available or not is calculated likeavailable > amount(lent)
-
The [PCL] is designed to be easily contributed to.
This application is just representing the state of two git-repositories. To alter the source-code or the component-library commit your changes to the respective repositories. Your changes will automaticly updated.
Attention: Test all your code locally before you push code to the git repository. An error might brake this site.Install the [PCL] locally
-
Clone the repository to your local file-system.
> git clone --recurse-submodules git@github.com:digitalmediabremen/pcl-code.git -
Disable cache invalidation plugin in
./site/config/config.php.// File: ./site/config/config.php ... c::set('cachebuster', false); ... -
Start a php webserver (you need to have php installed)
> php -S localhost:8000 -
Navigate to localhost:8000 with you web browser
Create and edit Components
the component-repository is a submodule of the pcl-code repository you just cloned.
locally its situated under(path of your pcl installation)/content/components.There is an
000-example-componentwhich you can duplicate and alter to your likings.
There are annotations for everything. The example component itself is not shown publicly.If you finished creating a new component or edited one, commit your changes (with an expressive commit message) and push your changes to github. You should see your changes reflected immediatly.
Create and edit examples
the example folder within a component is treated a bit differently from the other folders.
every folder within it is interpreted as an code example. source code files like.inoand.pdeare displayed inline with syntax highlighting. image files are treated like schematics and are also displayed inline.If you are having technical questions send an email to hi@leonat.de
