Printed Circuit Board Photo Collage Screensaver for OS X

OS X Flickr PCB Pool Screensaver
PCB Photo Pool Screensaver

One of my favorite ways to keep tabs on the Printed Circuit Boards Group on Flickr is with OS X’s built-in ability to turn an RSS feed into a screen saver, as shown above.

To create this cool and constantly changing screen saver, open the “Desktop & Screen Saver” pane of the OS X System Preferences, as shown below.

Desktop & Screen Saver Preferences

Click the + button and select “Add RSS Feed…”  OS X will prompt you for an RSS feed URL to use for the screen saver.  Enter

http://api.flickr.com/services/feeds/groups_pool.gne?id=812901@N20&lang=en-us

and click OK.

Make sure that the Display Style is set to “Collage” mode (the center option) as shown above.  Click Test and you should see photos from the pool appear on your screen.  Now the next time your screen saver activates, you should see a collage of cool photos from the PCB photo pool.

That’s it!

PS. If anyone knows of an equivalent screen saver for Windows or Linux, please let me know in the comments.  I don’t want OS X users to have all the fun!

Flickr Printed Circuit Boards Photo Pool Hits 100 Members!

100 wonderful, amazing people have joined the Flickr Printed Circuit Boards Group since I launched it in July of last year!

The pool features over 400 pictures of printed circuit boards, many of them CC licensed.  There’s a little bit of everything, from homebrew board fab to PCB jewelry and even miniatature cityscapes.

If you have some cool PCB images of your own, add them to the pool!

One of my favorites: Car Park or Printed Circuit Board?

DIY Light Tent

Homebrew Light Tent

I have always struggled to take decent macro photos of small objects to document my hobbies.  I finally got fed up with poor lighting and blurry shots and decided to build my own light tent to solve the problem.  There are lots and lots of examples on the web showing how to build a DIY light tent.  I wanted something cheap, small, and portable, so I merged ideas from a couple existing designs and used some scrap materials I had in the garage.  In the end I managed to make a light tent for about $35.

The major components are:

  • Light. I bought two desk lamps at Target for $9.99 ea.  I bought 100W CFL lights from Home Depot to avoid the unwanted heat and energy usage of conventional light bulbs, $9 for two.  I bought the color balanced type (3500K) which cost a little more but help accurate color reproduction in the photos.
  • Frame.  I used an old shoe rack, but almost anything can be made to work.
  • Light diffuser.  I tried bedsheets, which attenuated too much of the light.  Instead I used tracing paper (vellum) that I had left over from another project.
  • Background.  I used poster board from Target.  I bought one sheet each of 6 colors, for about $5.
  • Tripod – I didn’t have one so I bought the cheapest one Best Buy had, around $30.  Since I needed this for general use anyway, it’s not included in the total.

The results are really spectacular.  Now I can take macro shots of small objects without the glare and lighting problems I have experienced in the past.  For an example check out the photo below or see the complete set on flickr.

New Flickr group for photos of printed circuits

U1405

Printed circuit boards can be interesting and beautiful, with their delicate traces and colorful components in all shapes and sizes.  I just created a new Flickr group for photos of printed circuits like the one shown above.  More details about the group can be found on Flickr:
