“Whether they knew it or not, the interest that drew them here was purely psychological – the expectation of some essential disclosure as to the strength, the power, the horror, of human emotions. Naturally nothing of the kind could be disclosed. The examination of the only man able and willing to face it was beating futilely round the well-known fact, and the play of questions upon it was as instructive as the tapping with a hammer on an iron box, were the object to find out what’s inside. However, an official inquiry could not be any other thing. Its object was not the fundamental why, but the superficial how, of this affair.”
— Joseph Conrad, Lord Jim

“Nobody thinks clearly, no matter what they pretend. Thinking’s a dizzy business, a matter of catching as many of those foggy glimpses as you can and fitting them together the best you can. That’s why people hang on so tight to their beliefs and opinions: because, compared to the haphazard way in which they’re arrived at, even the goofiest opinion seems wonderfully clear, sane, and self-evident. And if you let it get away from you, then you’ve got to dive back into that foggy muddle to wrangle yourself out another to take its place.” — Dashiell Hammett, The Dain Curse

Cambot is a project based on the Teensy development board. Cambot creates an infra-red “trip beam” that triggers a pre-focused Nikon D90.

To create an IR beam and detector that work in direct sunlight, Cambot pulses the IR source every 10ms, and compares detected signal between the on and off states. If it’s greater than a threshold, it’s considered a valid signal. The sensor also has a vary small aperture which is additionally shielded with a filter to reduce the ambient IR. When powered on, Cambot goes into calibration mode, which lights up an LED when it detects a good signal. This is critical for lining up the IR sources and detector — once a good signal is sustained for 3 seconds, Cambot goes into “armed” mode. When armed, breaking the beam will turn off the IR source, half-press the camera’s shutter for 10ms so the camera can compute exposure, and then fires off a burst of pictures before re-arming itself.

While there’s nothing in Cambot that couldn’t have been implemented with, say, 555 timers, counters, and gates, having the ability to drive digital logic with C code makes things much more flexible. When trying to determine the proper threshold values for arming and triggering, the ability to output hex data over the USB connector to a host computer was invaluable.

Here’s Cambot’s first run, when the trip-beam was positioned over a tempting milkweed blossom in the back yard.

If there’s any interest, I’ll post a circuit diagram and source code.

Well, now, over the weekend was the 10,0000th download of our Royal Flutter font from dafont.com (the original distribution site). Of course, any free font distributed on dafont.com is copied and distributed through dozens of other sites such as MaxFonts, FontRiver, FFonts, Fonts2U, WebToolHub, and more.

I wonder what percentage of the downloaders actually use the font. I know there are plenty of font collectors out there. It can be addictive, looking at all the type faces, and thinking “yes! I could use that some day!”

Work progresses on a new (commercial) font which will likely be called Lunatrix. It’s a techno/space font, and will be available in five weights. Something more for the collections!

At last, a cure may be available for this terrible disease. Expect to see this ad in print magazines everywhere.
