New article etc

 Wed, 06 May 2009 11:32:02

I've again been lazy at updating the blog, but here's a small update. The second part of my articles on how to get started with Atmel's AVR microcontrollers is now online at Metku.net.

Once again, available in both English and Finnish:
» How to get started with microcontrollers - Part 2
» Kuinka pääset alkuun mikrokontrollereiden kanssa - Osa 2

Photo project "Project 365" still going strong (at the time of writing photos from about couple weeks are missing, but they are just waiting to get uploaded until I get a few things sorted out):

» Project 365 - All photos
» Month 1 / Month 2 / Month 3 / Month 4 / Month 5
» Project 365 - Photo of the Week
» Project 365 - Photo of the Month



Winter kite flying

 Sun, 22 Mar 2009 22:07:53

It was a nice sunny day today so me and my friend decided to go and fly a kite. We attached a cheap pen video camera on to the kite to get some video footage from up high. Below is a link to my friend's site where he has a photo of the setup and another video clip.

Site additions and Cactus V4 review

 Thu, 29 Jan 2009 11:16:14

I added a new section for articles as I felt it would be good to have it separate from the other sections. I already added one article there, a review of the new upcoming Cactus V4 wireless flash triggers that arrived yesterday.

Picture-a-day project

 Sun, 04 Jan 2009 20:38:25

I started a picture-a-day project few days ago when the year changed. The goal is to take and upload atleast one photo per day for the whole year, so there should be 365 photos at the end of this year. Quite a challenge and there might be some days without photos but I'll try to keep them coming as much as possible. At the moment I'm uploading the project photos to Flickr, but later I'll make an own page for them here, under Photography. As weeks go by, I'll tag one photo of the week every week and photo of the month from them at the end of each month (and at the end of the year, the photo of the year).

Happy New Year 2009!

 Thu, 01 Jan 2009 02:59:49

Yet another year has passed and here comes a new one, say hello to 2009. Year 2008 was good, there were all kinds of photography assignments, including election candidate portraits, funerals, weddings, christenings etc. They were good practice and I learned much while doing them.

Couple of photographs were also wanted abroad, other one went to China and the other to USA. Both of the requests were nice surprises. I'll reveal the first one later when it is a more appropriate time for it and the second photo was Space Invaders wall decoration that went for the Microsoft Softwear campaign, cool.

And next, some statistics gathered over the past year:

I finally got the website up and running 13 May 2008 and since then there has been (at the time of writing this), 115608 pageloads and 18473 unique visitors. The day with most unique visitors and pageloads was 30 July with 4543 pageloads, 1668 unique visitors and 1629 of them were visiting the site for the first time. The month with most activity was September with 4973 unique visitors. The top five countries giving traffic were Finland, USA and Germany. Site has got visitors from all over the world and I'm very pleased. Firefox was the most used browser with percentage of around 71% and Internet Explorer came second with 16%.

Top 5 referring sites and pages:
» StumbleUpon - Review of one project
» Hack a Day: Shell case your flash drive
» martybugs.net - Review of Cactus Wireless Flash Trigger V2
» digicamera.net - Diginews marraskuu 2008 [in Finnish]
» Electronics-Lab.com Blog - Rotating LED display

Thanks to all the visitors so far. There will be all kind of projects coming during this year, stay tuned!
Below is one of the photos from the 2009 fireworks from couple hours ago, more can be found here.

Over 10000 visitors

I looked at some visitor statistics of the site and the number of unique visitors (count by IP-addresses) as of 13 May 2008 has gone past 10000 mark today (almost 11k while writing) and number of page loads is over 60k. Thanks to all the visitors so far!


Photos back online

 Fri, 26 Sep 2008 02:38:37

All photos in the blog, projects and photography -sections are online again. My latest backup was two months old (oops, won't happen again) so I had to rebuild the whole data structure. Luckily I had a list of the uploaded files in the database and here is what I had to do:

  • File list from the SQL database.

  • Make an index file from about all the image files on my computer (I used cygwin so I could use those handy unix tools to generate the index file like this: find -iname '*.jpg' -print > image_file_index.txt)

  • PHP script that filtered all unneeded files from the image file index.

  • Another script that made a batch file with the info from previous script and that copies all the needed images to one place from around the hard drive.

  • Third script that made a huge batch file that uses ImageMagick's convert to resize and make all the needed thumbnails (two different sizes) etc according to the file information from the database and the batch then moved everything to the right places.


Maybe there would have been another way of doing all that but it worked so whatever. Also a lesson was learnt: REMEMBER THOSE BACKUPS!



Photo problems

 Mon, 22 Sep 2008 21:30:45

At the moment all photos in the blog, projects and photography are missing because for some weird reason, they all disappeared this morning. I'm working on it and trying to figure out what has happened.
