Electrodynamic fields can indicate moods and other psychological characteristics. A most interesting application of this theory was for birth control: the data showed that, through non-instrusive methods, one can determine exact moments of ovulation! The author was a medical student when his professor, an eminent scientist of the day, introduced him to the theory that all living organisms are organized by measurable electromagnetic systems. Though it’s a concept that has never been fully embraced by the scientific community, it was an idea that sparked a young man's imagination and has been the inspiration for a lifetime of intensive research. Throughout his successful career as a psychiatrist, Dr. Ravitz has continued to measure, document, and explore electromagnetic fields with respect to the function of the human brain. Electrodynamic Man presents the exciting discoveries and innovative applications that his research has yielded in a cogent, accessible overview of an avenue of inquiry that opens up provocative new perspectives in the fields of science, medicine and philosophy. 268 pages 2002. Published at $23.95.

This compact PC-driven sampler monitors voltage changes over periods ranging from milliseconds to months. It can also be used as a simple low frequency digital scope to examine audio and other signals up to about 5KHz. No batteries are required as it is powered from the computer’s parallel port. Uses an 8-bit A/D converter with a 1.235V reference voltage so the Sampler has a resolution of approximately 10mV on the 2V range and 100mV on the 20V range. Revised software (ISEE_V301.zip) is avilable here: http://www.crowcroft.net/kitsrus/isee_v301.zip Works with W9x/ME/2000/XP. Requires assembly and soldering.
Pocket Data Logger/Sampler ......................... $19.00
The O-SCOPE I is a pocket-size module which plugs into the printer port, tranforming a PC (286 or higher) into a digital storage oscilloscope. Included in the package are frequency spectrum and data logging modes of operation. Working with a desktop, laptop or notebook computer, displayed sweeps can be captured on the screen, saved to disk, and output to a printer via the DOS print screen function. In the oscilloscope mode, sweeps are displayed on a 6 x 10 division grid which is six times larger than a typical oscilloscope grid. Each Sweep is based on 500 sample points. Operating parameters such as input range, sweep rate, and trigger level are displayed and easily adjusted through the computer keyboard. Also displayed are calculated voltages, frequency and period. In the spectrum mode, sweeps of a selected frequency range are based on a 256 point FFT. The highest peak is automatically scaled to zero dB so that no peaks are cut off. Because of the logarithmic intensity scale, even low harmonic content is visable.
INPUT: 1 megOhm imp. with about 20pF cap. BNC connectors accept standard x1and x10 probes. AC or DC input selection. DISPLAY: 6 x 10 div. scope grid (or calib. freq. spectrum graph) along with alphanumeric operating parameters, voltages, freq. and period. EXTERNAL TRIGGER: 1 megOhm imp., 10pF cap., 3.5 mm phone jack. Modes: AC coupled, edge sens., or +/- edge. Sensitivity 75mV.

Need to measure DC magnetic variation from place to place down to a resolution of .01 milligauss (= 1 nanotesla, or 1 gamma), which is about 1/500 percent of the earth's field strength? Because the earth's field fluctuates by typically 3-30 nanoteslas per hour, a resolution better than 1 nanotesla will not be of much additional benefit. The Earth Magnetometer is a vector magnetometer, and it must have its sensor pointed (at least momentarily) within one-third of a degree of the correct field direction in order to measure the actual field to .01 milligauss precision. The Earth Magnetometer includes an analog meter (needle-type) to tell you if you're tipping the sensor closer to or farther from the correct position. It measures difference in field strength to accuracy of +/-0.5% of the difference, either for point-to-point or time-to-time measurements. In other words, if one location is 2.00 milligauss (200 nanotesla) stronger than another location, the Earth Magnetometer will indicate that difference to accuracy of +/- .01 milligauss or 1 nanotesla. Also includes an “offset” function that adjusts the display to a reading of zero +/- .01 milligauss at whatever time you want to. Then you can measure how many nanoteslas stronger or weaker the field is, compared to your starting point.
Earth Magnetometer ......................... $700.00

"Get That Laptop Off Your Lap!"
"Grow Your Probe!!"
This is a high quality 1-axis E + M meter made in Germany by ROM-Electronik GmbH. Digital readout, with our without sound, and frequency range selection. External probe allows precision positioning. Electric field measured in V/m, Magnetic field in µT. You also get AC/DC voltage output for datalogging or spectrum analysis.
Stretchy silver coated sheer nylon weave. Will shield low intensity radiofrequency and microwaves (with a shielding effectiveness up to 67 dB at 1 MHz and 33 dB at 1 GHz, actual results may vary depending on your shield design and other factors),
and is an excellent E-field shield when grounded. Resistivity: <5 Ohms/sq. Create your own designs. Many uses! Sandwich 
it between your bedsheets, line a vest, cover your microwave oven, computer monitor or keyboard, stereo, light cords, circuit box, vacuum cleaner, make a hat, lampshade, window drapes, etc, etc. Delicate fabric, rubbing and heavy handling can cause grayish silver to wear off.
True 3-axis sensors insure that measurements remain accurate regardless of the orientation of the instrument, making this the easiest digital gaussmeter to use, by far! Just turn on the switch and take your readings. Lightweight and self-contained, this unit is ideal for commercial and home use. Applications include detecting magnetic field emissions from a wide variety of sources, including video display terminals (VDTs), AC power lines, office equipment, household appliances, and all types of electronic equipment.
Simply add a socket to the free end of the above cords to make nice quality (and low cost) extension cords. Easy to do with a screwdriver. Simply cut wire to desired length and add a socket to the free end.
These sockets are suitable for North America. Color/style may vary.
The is 
DIN 5 female to mini-DIN 6 male. Gold plated contacts, molded PVC boots. Fully shielded. 4" wire; 7" total length. If your keyboard has the large 5 pin plug and your computer (or extension cable) has the small 6 pin plugs, this is the adapter for you.
