Bicycle Camera Mount Alternate Use


Todd Schlemmer recently suggested that I feature this excellent-looking Minoura Handlebar Camera Mount (Amazon), which I’m quite happy to do.  I haven’t used it myself, but according to Todd, he was “very impressed by its solid construction and bikey part appearance.  The cork is totally Japanese old school.”*

It does look quite solid, but naturally I was curious to see what he’s come up with using this device so far.  Todd was kind enough to point me to his Flickr photostream, where he’s documented his setup for videoing a 3D printed camera build.  According to Todd, these photos are “very noisy and representative of both my cognitive method and work space.”  I can relate to this.

Although it’s not attached directly to a bicycle, the mount is fixtured to a pole resting on a bicycle, which seems fitting to me for some reason.  Also of note is his use of clamp lights, which I’ve found to be very useful for making good better quality videos.  Here’s my DIY clamp light stand.


I’m sure the assembly footage will turn out great, and hopefully I can feature it here!

*He should know, as he was recently kicked out of a local Japanese garden for using a Tripod.  Apparently he’s considering his options for making s “stealth tripod.”

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.

GoPro Third Person View in Real Life

gopro-third-person-view-rig Many – I suppose most – video games show the player in a third person view, as if the camera was watching your life from the outside.  Have you ever wondered what would happen if this could be done in real life?  Apparently if you have two GoPro cameras and an Oculus Rift virtual reality headset you don’t have to wonder any longer.

Although I can only imagine how this would feel, I generally see about a second of lag between what happens in real life on my GoPro and what is displayed on my iPad or Android device.  This could be quite disconcerting.  Check out the video after the “read more” link to see how this works.
