// big time o'clock

update 25.09.2012
- the radio control module was replaced with a RTC (DS1307) because of the poor signal.
- the display driver was replaced with 6 shift registers

big time o'clock is a radio controlled clock with a large sized display designed for an office wall. Here is a source of inspiration.

Snapshots of the radio module, led-driver and the test display.

A temporary led installation made up of 5 white boxes with snowflake patterns that light up randomly.

This application is based on the concept of altering reality through the internet.

One can basically control a 4x4 led-lamp on my desk using an applet on a webpage - a grid that lights up when moused over and then fades out again. These commands are sent through a server to an arduino board that controls the led-lamp. The feedback is then visible on the same webpage through real-time streaming.

The interface (webpage) is made up of three elements:
- the input grid that lights-up when moused over
- a control panel with switches and potentiometers for ajustment purpouses
- the applet containing the real-time stream

// Image Info

Image Info creates a new layer containing the following information about the current image:
  • custom title
  • complete path & filename
  • image size
  • resolution
Helpful when you print lots of images and then you try to identify one of them.

The image is resized, so no content is lost. The height of the new layer is relative to the image height, so there is a possibility of unreadable text if the images are too small.
There is a little room for customization while all the fields are optional. On the layer the fields will be written from top to bottom (eg: if the custom title is missing, the image path will take its place). Colors are settable too (for text and background).
In GIMP (2.4.x and 2.6) the script is installed under the menu <Image> -> Add Image Info.
  • batch-mode processing (probably will lead to a python version of the script)
  • UI: a switch to choose whether the info is rendered on a new layer or directly on the image
  • embed EXIF information as fields for jpeg images taken with a digital camera


// microCounter

microCounter is a simple web-based counter written in PHP. it uses a visitor tracking system based on the visitors ip address. the counter stores the data in a mysql table.
microCounter saves the minimum information needed (session, hits/ refreshes,date, ip, filename) - decreasing the loading time of the webpage - but it offers detailed information (based on the records made) about visitors (number of refreshes/reloads, hostname, country, referrer domain, file downloaded) and traffic statistics.
a filter can be used to ignore specified ip addresses. the filter file can be edited manually for now, but in the next releases of microCounter the filters shall be defined via the frontend. a complete log of microCounter's activity is saved for later viewing.
microCounter defines a group of PHP functions which can be called from html or another PHP code to retrieve the recorded data. a web-based interface (using these functions) can be used to handle the database (create/empty/backup table), view records (last visitor, unique visitors, all visitors), view/ edit the filters, view/delete/save the log file.
