The PSI Science Lamp (old Telephone to God (TTG)) circuit provides several fertile areas of cutting edge research for readers to dabble in; from influencing the probability of decaying radioactive particles (quantum mechanics), aka mind's influence on nature and machines to precognition and telepathy.
The circuit can be used for testing PSI; precognition, telepathy and psychokinesis (PK). In a pinch, it can even be used as home radioactive bomb/fallout detector. And when not used in any of the above applications it's a truly random mood light with a very high coolness factor.
History of the PSI Lamp
When I designed this circuit I had thought it original to me. My company has turned this circuit into a small commercial product. A series of events cause me to look to see if a RNG had ever been connect to four different color lights to test for PSI and PK. Searching through the Internet I found that connecting a "Geiger counter" RNG, to a modulo four selector to four different color lights for the expressed purpose of testing PSI and PK had been done in the 1960's by Helmut Schmidt.

Not only had my circuit been created before, but in almost the exact same manner.
Helmut Schmidt had made many RNG devices, this was only one of them.
PSI Science Lamp Disclaimer:
When used as a fortune telling device, ie, "PSI Science Lamp I make the following disclaimer. The PSI Science Lamp, is based upon the randomness of radioactivity, the user's interpretation of these random events is their own responsibility. The PSI Science Lamp is offered as an entertainment device ONLY! I do not accept any responsible for any results consequential or inconsequential from the use or misuse of this device.
Einstein is quoted as saying God does not play dice with the universe.To which Neils Bohr replied, Einstein, stop telling God what to do with his dice."
Our PSI Science Lamp relies on the randomness of radioactivity. The built in miniature Geiger counter detects background radiation. Background radiation consists of three sources: cosmic, terrestrial, and internal. Cosmic radiation comes from the sun and stars. Terrestrial radiation comes from low levels of uranium, thorium, and their decay products in the soil, air and water. Internal radiation comes from radioactive potassium-40, carbon-14, lead-210, and other isotopes found inside our bodies.
Connected to the built in Geiger counter is a PIC microcontroller that uses the random time interval between the detection of radioactive particles to trigger the selection of a random number between 1 and 4. The random numbers generated by our PSI circuit are truly random. The Random Number Generator (RNG) will produce approximately one to two random numbers every minute.
As stated, the PSI Science Lamp generates a random number one through four. Each number is assigned to a color LED that is displayed in our lamp unit attached to the phone. Number one is assigned the color (1 =) Red, two is assigned the color (2= ) Green, three is assigned the color (3 =) Blue and four is assigned the color (4 =) Yellow. Feel free to mix up and/or change the LED colors, as you desire.
Fortune Telling - To use this device as a fortune telling device, assign answer values to the LED colors; for instance red = No, green = Yes, Blue = maybe, and Yellow ask again later. Something like a color light magic 8 ball. Ask the universae a question and wait for the color light reply. Is this any better than a magic eight ball? That's for you to decide?
Other fun and useful applications:
The PSI circuit can be used in the same manner as Helmut Schmidt's RNG device to test for precognition and psychokinesis.
Precognition Test - The PSI Science Lamp, displays one of four colored LED light in a truly random sequence. Here the experimenter tries to guess the next color that will be lite. By correctly guessing the next color to be displayed, statistically greater than chance (one in four) alone would account for then experimenters show precognition.
Psychokinesis (PK) - Influence of the Mind Over Machine: Helmut Schmidt PK experiments in the 1960's followed this procedure. The subject tries to make one color come out greater than what would be allowed by chance. If that color id outputted by the device statistically greater than chance would account for that the experimenter can show PK.
PEAR is an acronym for the Princeton Engineering Anomalies Research. This interpret group of people led by Robert G. Jahn studied the mind influencing the behavior of machines, and proved a statistically correlation.
Random Number Generator (RNG) - Our PSI circuit can generate truly random numbers. You may question the need for random numbers. True random numbers are useful for data encryption (cryptography), statistical mechanics, probability, gaming, neural networks and disorder systems, to name a few.
Mood Light: The randomly changing colors from the lamp are a soothing. You may consider the randomly changing colors as an example of the Universe talking even if no one is listening.
"Radioactivity Detector" The PSI circuit may be also be used as a nuclear bomb/fallout radioactivity detector. If the Led's start flashing at a greater rate of two changes per minute for any length of time, you may be experiencing higher than normal radioactivity in the area.
How Random Numbers are Generated:
The way the random number generator operates is simple to understand. However, its fundamental function is best described using a mechanical analogy. Imagine if you will a sequence of numbers painted on a revolving wheel. A pointer is fixed on the outside of the wheel pointing to the number at the top of the wheel. The wheel is set into motion, spinning very rapidly. Then at any given random moment the wheel is instantly stopped. The number under the pointer becomes our random number. Once read, the wheel is set back into motion.
The microcontroller program follows pretty close to the mechanically analog. The microcontroller spins the sequence of numbers; one thought four internally, in a for-next loop. The random point in time when the sequence of numbers is instantly stopped is generated by the detection of a radioactive particle by the tiny built-in geiger counter. The number is read, displayed via LEDs and sent out serially on the TTL port , if one wishes to perform other random number generator (RNG) experiments.
Please note: this video shows the PSI Science Lamp with radioactive element nearby to induce faster random number generation. When used under normal conditions, the PSI circuit will generally produce about 1 to 2 random numbers (color changes) a minute.
