Captured with: Nikon D7000
Footage edited with: AE, PremierPro.
Glass: Nikkor 24-70mm f/2.8G

We had a guest – Darth Vader in our city. A famous one. Well known to everybody who loves sci-fi ;)
May 14-15 is a day when the Lithuanicon’2011 will take place in Hotel “Holiday Inn”. Do not miss that! :)

This was a 2nd time when I used a tripod like a shoulder rig. I would side, it works like a charm!

Weekly Project: HudsonLifeSupport

Sunday, December 5th, 2010

In short

Arduino based box is connected through the USB with the software module which periodically checks the Hudson job status and triggers the appropriate LED on the box. Software module is based on Java and use RXTX module for communication with the Arduino board.

What is the Hudson CI server?

“<...>Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron.” More details about Hudson can be found on Hudson WIKI

Hardware Required

1. Arduino Board
2. 10-kilohm Potentiometer
3. 7 segments LED
4. Blue, Yellow, Red LED’s
5. Few meters of wire

Build story

This is a simple project to provide detailed build story steps. In short: potentiometer is connected to HudsonLifeSupport box to configure the timeout between the the status retrieval from Hudson server. While rotating the potentiometer 7 segment LED shows the number of time units to countdown. Moreover, during potentiometer rotation the HudsonBuildBox turns to the configuration mode. In case the potentiometer value stays the same for 5 seconds, countdown clock starts. When the countdown is close to zero HudsonBuildBox sends a signal to the software module to retrieve the build status for a configured target in Hudson CI server. Software module retrieves the build status thanks to Hudson XML API.

In case build is successful the BLUE light is triggered.
In case there’s failing unitests YELLOW light is triggered.
In case the build is failed due to compilation errors RED light is triggered.
In case Hudson server is not reachable for some reason (no connecion, server is down) all the LED’s turns to blinking mode until the Hudson server is up.

Code base & Arduino firmware will be posted to GoogleCode next week. Or if you can’t wait drop me an email with your question ;)

Party time & tuned UltraHD

Monday, November 15th, 2010

Mini project #2 after my grand 1st one: Last week I had a change to test my new setup of my UltraHD camcorder.
Led dim lighter, mono-pod & glued wide lens of 37mm. Worked like charm in low light conditions. Just double check the glass when you gluing a lens on it. In my case the whole surface of video glass was piled by superglue steam. It caused a natural blur filter in final footage. Also dim light was filtered by white paper do restrict direct dim light to the subject. Doing so will help you to keep your subject as close as possible to your camera without distracting it with direct light.
  
Final shot – caught in action :)

Next day (Sunday) was flying day. Rainy but flyable. Also thermal activity was also in the air, but not for me due to rainy clouds and dirty ground at that time. Some shots from the Sunday sky:

Feedflow

Saturday, October 2nd, 2010

Facebook, twitter, your home page, your online albums ant etc.. All of those are reflections of your life in many formats. Some of them are published to social media, some of them are left in a shadow.
My mission here is to accumulate all those flows to the singular point and make it self living organism.
Twitter, home page, online albums like Picasa have a rss feed. By using rss feed and online service http://twitterfeed.com you can setup an automatic rss feed re-publisher to a few services like twitter, facebook, statusnet, ping.fm, hellotxt.
http://twitterfeed.com was my choice of the simplicity & free of charge service. Alternative would be to use http://feedburner.google.com, but this one does not have a facebook connector.
The draft concept would be something similar to:
feedflow

Main feed flow from picasaweb, own pages (home page), vimeo account are published to twitter account. Twitter account feed is published to Facebook. Also Linked in account is connected to the my own home page through the Linked in wordpress connector.

Docking your Projector

Sunday, February 21st, 2010

How would you mount your projector? Driling some holes in the walls? Buying some ugly docking stations and again driling the walls or living room ceiling? I came to simple solution by playing with the regular tripod and two monopods:

1. stable.
2. portable.
3. ajustable.
4. durable & resistant even to the golden retriever tail movements :)

p.s. In my family there’s no place for TV. And we keep this status for about 3 years.
