More Sky Time Lapse Videos

Posted by on February 28, 2013 No comments

After a really cool propane drum construction time-lapse in the last post, here’s a few more. The first is a time-lapse of the daylight sky with two layers of clouds crossing each other in different directions.  It made for a really cool effect:

After the “read more” are two other time-lapse videos I’ve made.  The first is of a place called “Lake Clinch” in Frostproof, Florida, and the other is a night sky time-lapse video.  I’ve shown the second video before while reviewing the equipment I used, but the first is new to JcoPro.

CNC Light Painting: Some Refinements

Smaller LED and cutoff added here, but no taped sides or remote trigger yet.

There were some cool light painting effects in the last post, but to truly do any sort of “presentable” light painting, a few things had to change.

To begin with, with the small canvas that I was working with (approximately 2″ x 10″), the light source needed to be smaller.  This was accomplished by using a 2 color LED by itself instead of the flashlight.  As an added bonus, being two colors allowed it to switch colors mid-stroke if needed.  I don’t have this hooked up to switch yet, but it could be a neat effect.

The second thing that would need to change was Read more »

CNC Light Painting: First Attempt

backwards "J" light paintingAfter buying a Canon T2i camera a few months ago, I’ve been really excited to play around with different exposure settings and possibly some time-lapse photography.  The first trick that I’ve tried is something called “light painting.”  How this works is that your camera is held still and a light is moved around with the shutter open.  With the lens open it captures this light wherever it moves in the frame.  Alternatively, the camera can be moved around a light.

The photo to the right was made by moving the camera, but my idea was do light painting by moving the light.  As with making stencils for a bleach t-shirt, I don’t necessarily feel I have that much artistic skill, but I do own something that allows me to fake it, my CNC router.  The idea that I had was to attach a light to the X and Z axis and allow it to either be controlled manually or run a Gcode program Read more »

Capacitor Safety for Cameras

Posted by on March 21, 2011 1 comment

Capacitors are fairly common components when it comes to modifying/breaking electrical components.  However, they can be quite dangerous.  According to “repairfaq.org“,

“While accidental contact with capacitors on a 3.3 V logic board isn’t going to result in a shocking experience, this is not true of many common types of equipment including TVs, computer and other monitors, microwave ovens; the switchmode power supplies in some VCRs, laptop computers, camcorder battery chargers; electronic flash and other xenon strobes; laser power supplies, and many other consumer and industrial devices.”

Most people familiar with electronics should know to be careful around TVs, but what many people wouldn’t think about is the smaller things, especially electronic flash devices.  Quite a bit of power is required to use a flash, and as such, quite a bit is stored in a camera’s capacitor.
