Build this Negative Ion Detector -  Figure 1 shows a schematic diagram of the Ion Detector--a rather simple circuit consisting of three transistors (two PN2907 PNP, and a single PN2222 NPN type) , three resistors, one capacitor, an antenna, a mA meter, and an LED. . .  [by Vincent Vollono]

Controlling Stepper Motor with a Parallel Port -  Another chamber was constructed with a large cookie tin similar to the peanut can design above. The performance of this much larger chamber was excellent. A single Coleman lantern mantle nearly "pegged" the output. The background radiation. . .  [Charles Wenzel (unless otherwise noted)]

Even Cheaper & Simpler Ion Chamber -  Here is a really simple version of the above chamber that is surprisingly sensitive for its simplicity. It uses the same coffee can as above but only one transistor. Here are step-by-step instructions for constructing this really easy-to-build version. . . .  [Charles Wenzel]
Ion Chamber Bias Supply (Battery Topper) -  After discovering that one of my bias batteries was jumping around a few volts, wreaking havoc with the readings, I decided to build a floating, regulated high voltage supply. The result is a micro-power 110 volt supply that runs on an ordinary 6V lantern. . .  [Copyright 1998 Wenzel Associates, Inc.]

Negative and Positive Ion Generators -   These Ion Generators can create either Negative or Positive Ions into the air from the Air. The Pins produce the Ionization of the air at the Points of the Pins. A Fan is useful to help disperse the Ions into the room. Voltages greater than about 6, 000 volts Will create some Ozone, which can be harmful to a persons health. Even though this is a Static Voltage, It can give a BAD Shock if Touched. SO BE CAREFUL. . .  [G.L. Chemelec, designer]

Negative Ion Detector -  Figure 1 shows a schematic diagram of the Ion Detector--a rather simple circuit consisting of three transistors (two PN2907 PNP, and a single PN2222 NPN type) , three resistors, one capacitor, an antenna, a mA meter, and an LED. . .  [article by Vincent Vollono]

Negative ion generator -  Schematic only, no circuit description. . .  [Designer's name not given]

Negative Ion Generator #2 -  The design of the Negative-Ion Generator is fairly straightforward (see Fig. 1). The circuit is a high voltage generator. It contains a standard 555 timer that's used to generate square-wave pulses. The pulses are applied to the base of the TIP120 NPN Darlington transistor. The Darlington provides sufficient current to the base of the 2N3055 power transistor to turn it on. Each. . . .  [article by John Iovine]

Negative Ion/Static Electricity Detector -  A sensitive detector for static electricity based around a single Field Effect Transistor It can also be used to detect the presence of negative ions, or test a negative ion generator. . . .  [Andy Collison]

PicAXE Ionization Chamber -  This simple radiation detector uses a PicAXE-08M microprocessor to measure the voltage drift rate on an ionization chamber's sense wire, eliminating the need for a high-value resistor. An electrometer-grade JFET is used to buffer the voltage on a sense wire inside the chamber, and a PicAXE microprocessor measures the rate of change of that voltage, periodically discharging the wire through the JFET's gate-source junction. This unorthodox way of discharging the ion chamber wire eliminates the need for a special, low-leakage switch, and takes advantage of the PicAXE's ability to use the same pin as an analog input or a digital output. . . .  [Copyright 1998 Wenzel Associates, Inc.]

Radon Detector for the Student -  This ionization chamber radon detector is designed to be easy for the student or hobbyist to build and use. It can form the basis for a variety of experiments for Science Fair competitions, class projects, conversation pieces, or simply satisfying scientific curiosity. Despite the extreme simplicity, the chamber can detect surprisingly low levels of radon by detecting the radioactive "radon daughters" produced when radon gas decays. The detector could be used to investigate a variety of scientific questions and demonstrate scientific principles:. . .  [Charles Wenzel, designer]

Static Electricity Detector -  A sensitive detector for static electricity based around a single Field Effect Transistor It can also be used to detect the presence of negative ions, or test a negative ion generator. . . .  [Andy Collison]
