Bert's Quarter Shrinking Gallery
Small tube electromagnets with very large power discharges make for a way to magnetically crush coins placed inside the tube. Bert's gallery has a selection of photos and description of the shrinker and a larger collection of photos of the effects.

Website that can convert photos and logos in jpeg form to vector images in postscript or SVG format. Very handy for making a photo into a logo.

Rockland Colloid Photographic Materials
Make your own "paper" with Liquid Light emulsion, brush it on any surface, then use that like black and white paper. Plus other photo development fun stuff.

One man's (Phil Agre's) commentary on inexpensive disposable pens. No pictures, just text. It would be nice to have reference pictures of the pens, but oh well.

Print Gocco is a Japanese silk-screening machine. It uses a safe (less toxic than usual) photo sensitive screen and a squeegeeless print method.

This started out as a post about a new toy available in Japan to make audio records (as in "gramophone") on CDs and other flat discs, and branched off to include some other related ideas. I want one of those toys.

A small webpage devoted to the failed kids toy, the Fisher-Price PXL-2000, which records video onto audio tapes. 5 minutes of grainy black and white video per 90-minute cassette. I remember when these were new, and contemplating buying one. I should have done it.

"The Mumford Time Machine is a programmable controller and intervalometer for special photographic effects. It allows you to trip the shutter of your camera or fire an electronic flash at specific intervals or in response to events. These trigger events can be sound, light, motion, or electrical signals."

A page about the Fisher-Price toy video camera, the "Pixelvision." It recorded video onto regular audio cassettes, 5 minutes of video per 90 minute audio tape. I remember seeing these for sale when new, and I still regret not buying one.

A Thrill in the Dark - Victorian Magic Lantern Shows
I found this site looking for information about magic lantern optics. Besides having a page devoted to that topic, it has a fair sized gallery of slide images, information about various types of lantern, slide restoration tips, resources and links, etc.

Very accurate sundials with easy adjustments for longitude and latitude. These are much prettier than the "World's Most Accurate" sundials, and much cheaper than the "Precision Sundials".
[2005 May 11] [/tools/time] [#]
This sundial uses specially cut masks to make shadows in the form of a digital readout. It doesn't try to show time intervals of less than ten minutes, so it isn't very accurate, but it sure is nifty.
[2004 Oct 26] [/tools/time] [#]
This site offers double sundials, to tell both solar and time zone time, and a helical sundial which uses special lenses to focus a line of light, instead of a shadow, on the current time. The second is adjustable in two ways, the angle can be set for your lattitude (no need to to custom build to location) and the time markings are on a slider to adjust for daylight savings time and the equation of time.

World's Most Accurate Sundials
Sundials and plans for sundials calibrated for the specific mounting location. This calibration is necessary to adjust the shadows for the height of the sun (lattitude adjustment), these clocks go further and adjusts for longitude so the clocks will display time-zone time instead of solar time. Standard time or daylight time zone calibration is an option. Even still the sundials will vary because of the "equation of time" due to differences in the speed of the Earth at different places along its orbit of the sun. So these come with a reference table for the adjustments needed, which you have to do after reading the sundial.
