An Easy to Use Lens Hood Cap

Lens hoods are an interesting accessory, meant to block light from coming into your shot at unexpected dimensions.  Unfortunately, they make putting a lens cap on very difficult if not impossible.

If you’re not satisfied with the fact that the offset does protect the lens somewhat, my extremely simple solution was to simply use a larger-sized lens cap than the lens uses on my hood.  This 58mm hood (Amazon) fit my Canon T2i DSLR’s kit lens, and a 62mm lens cap (Amazon) made a perfect lens hood cap.*  See after the “read more” link for a GIF of the process.

Seriously easy.  I’m really pleased with how this worked.

Automatic Rotation for a Plant Growth Time-Lapse

Plant Growth Time-Lapse setup

I’m a big fan of time-lapses, but they are almost always more interesting when some sort of motion is involved.  Normally the camera is rotated to make the subject (the world?) appear to move, but in this case,* the subject is a tiny grapefruit plant, photographed over several days of growth.  It’s not a lot as of now, but you can see the resulting video after the “read more” link thing.

A scroll saw was used to cut most of this beautifully finished time-lapse rig, and a Shapeoko CNC router was used to cut the circular piece.  I suppose one could also use a large hole saw if you didn’t happen to have a CNC router around.

A stepper motor drives the belt below the camera at a rate of one step per picture, which, in conjunction with the gear reduction going on, allows for a very slow rotation speed.  Cleverly, the plant’s wooden pedestal is balanced on a cooling fan, acting as a thrust bearing for this relatively light load.

Servocity Camera Slider Review

Servocity camera slider reviewRecently, Servocity was nice enough to send me one of their “Channel slider A” kits.  I had a great time putting it together and trying it out.  In my limited experience, it’s incredible to see how good video shots of something quite mundane look when steadily panned over a distance.

Servocity isn’t the only company in the “camera slider game,” but the price seems quite reasonable compared to other similar models.  Also, the design is such that it’s made to be customized and modified however one wants.  Although they sell mounts for GoPro cameras, and smartphones, I didn’t actually have one, so, as shown later, I was able to make one myself from bits that I had around my garage.  Th results were quite good as shown in the video after the “read more” link thing.

Sold separately, Continue reading
