I created a Arduino controled led clock with 60 rgb led’s. This one is inspired by the Equinox Clock from Bram Knaapen.
For time keeping I am using a a RTC DS1307 that is connected via I2C to pin A4 and A5 on the Arduino. Pin 7 from the DS1307 is connected to pin D2 on the Arduino an is set to a 1Hz Square Wave. I am using this to give the Arduino every second a interrupt, this made the timing a lot easier. I build the DS1307 on a custom should with breakout pins.
There is also a LDR connected at pin A2, this wil measure the light and dim the led’s accordingly.
For the design of the casing I am going for a 12 angle shape. The edge will be layered with sanded plexiglas sheets for a nice glow effect. The LED’s will in a aluminum bracket. Here is the first design what I made in google sketchup.
The led string if all rgb leds are on will draw about 3.6 Amps at 5 volts. This of course is way to much for the Arduino regulator. But most of the time not all led’s will be on or at full brightness. Now I am using a switched 5.1 volt / 2 Amp power-supply that I had lying around. This power supply is directly connected to the + 5v on the arduino. So it’s bypassing the regulator on the Arduino.
Here is a short video overview from the first proto type, this on is fitted in a carton box, so nothing fancy yet. Now I need to get my hands on a laser cutter to build the casing.
All the files, codes and sources of this project you can find on my github.
To use it, just go to my Yahoo Pipe fill in your latitude uid and map size for your static map image and get your RSS feed. Please let me know how you implement this feed.
With the inlinefeed plugin you can display and embed RSS/ATOM feeds in your WordPress posts and pages using the following shortcode:
NOTE: From version 2.0 you can only use the shortcode [inlinefeed], the old style `<!–rss:[URL]–>` doesn’t work anymore! If you upgrade
from a 1.xx version, then you must change from `<!–rss:[URL]–>` to `[inlinefeed rss_feed_url=”http://feed.xml”]` style..
Look for some examples in the txt file thats included in the zip file.
2.01 truncate title accpets now a nummeric value. New option, displayfeedname.
2.00 Now uses the wp 2.5 shortcode.
1.62 Error handling and headers are giving descriptions and are clickable.
1.6 Added option newwindow. If you want to open in a new window.
1.5 Fixed a bug that the feed got bumped up to the top of the page.
1.4 XHTML compliant.
1.3 Truncate title.
1.2 minor fixes.
1.1 Initial release.
If you like those little buttons on your site to show off, here is one for inlinefeed:
If u want to use Inlinefeed to display rss feeds that are offered in gzip format, please take a look at the modified class-snoopy.php.
Flickramio is a Greasemonkey script that put 2 google earth map’s next to the photo if the image is geotagged, so Flickr looks a little more like Panoramio. And if you have already the Google Earth plugin installed, you even can see it in 3D.
Here some screenshots:

Some people ask me about my geotag workflow on my site, so here it is:
My hardware: Nikon D80 DSLR and a Qstarz BT-Q1200 GPS logger with spare battery. This logger uses a nokia battery. So it’s easy to get a replacement.
1. I shoot in RAW (NEF).
2. GPS logger, is always logging at 10 seconds interval when I walk around with my cam.
3. The software that’s included from Qstarz is not so good, so I use the alternative bt747 software to read the date and convert to GPX, NMEA and KML files.
4. With GeoSetter I geotag my raw NEF’s. Also this tool ads place and country and location names as exif tag.
5. Import in Lightroom. Lightroom see also the place, province, and country names as exif tag’s.
6. Process in Lightroom / Photoshop en export to jpg and put it on my flickr.
So this is basic my workflow.
