Watch as this water seemingly freezes and then moves in reverse. A pretty swag optical illusion caused by the water passing in front of a speaker playing a 24hz (and then 23hz) sine wave and the video being recorded at a synced rate of 24fps.

Turn your iPhone into a vintage rangefinder camera with the snazzy iCA case from Gizmon. No apps required, no funny business, just point and click the shutter release to take a shot. Not a bad way to disguise your iPhone, unless you’re trying to hide it from hipsters in which case it would totally backfire, totally. The iCA is priced somewhat reasonably at $65 — now that I think about it, that doesn’t sound reasonable at all, $65 and you have to provide the camera? I hope that’s real leather(ette). Currently only marketed in Japan, but you can order direct or through a number of U.S. importers.
A large boulder stopped on its way down a sloping wall — on the freaking moon! Some suggest that this venture was triggered by an impact of some sort. I guess we’ll have to send a probe to determine once and for all whether or not a rolling moon stone gathers any moss.
After having fun with some infrared and macro photography I wanted to try some time lapse. Some cameras have built in intervalometers ( big word for interval timers ) which allow you to do time lapse with little effort. Sadly the Canon Rebel XT does not, so I searched around for solutions, most of which are quite expensive.
I found out some useful information:
- the Rebel XT has a 2.5mm stereo jack connection for remote operation
- connecting the ring and base of this jack trigger the autofocus
- connecting the tip and base of the jack triggers the shutter
With this information I hacked together a makeshift solution with a 12v relay, 12v wall adapter and an X10 appliance module. This system sucked and wasn’t portable, but it was all junk I had laying around. Anyhow, I went back to searching and found out about the TC-80N3, a Canon wired remote which does all sorts of fun timer stuff, including time lapse and goes for under $100 on eBay now and then. Unfortunately it doesn’t work with the Rebel XT, the connector is different, out of the box at least.
I found out that it has three leads on the connector, as the Rebel does, so perhaps they function the same? It seemed to be the case so I went and purchased one, hoping to just swap the connector out.
Once it arrived I went straight to hacking it up. Chopped off the old connector, found out that there are two wires and a ground wire, sweet. With the help of my multimeter I determined that the red wire is the shutter and the white wire is the focus. So, to attach the new connector:
- solder the red wire to the tip of the 2.5mm jack
- solder the white wire to the ring of the 2.5mm jack
- solder the ground to the base of the 2.5mm jack
Slip the cover back on or tape up the connector, whatever, and it’s all done. The Canon TC-80N3 modified to connect to and control a Canon Rebel XT. Doesn’t need much know how at all to pull this off.
