Keep the lamp on for a fixed time after S1 is pressed. Do not use with another type of lamp. The circuit can operate on both 110 V and 220 V mains with lamps up to 100 W. The circuit is half-wave, ie the lamp lights up with half the normal brightness.
An interesting paranormal theme which has a strong scientific foundation and is even used intensively in research is what involves the detection of water, minerals, and petroleum quarries through sensors capable of perceiving small changes in local gravity. The scientific basis lies in the fact that sensitive devices can actually do this detection. Paranormal research, however, involves the possibility which people may notice these variations and detect the quarries using pendulums, forks, or other less technical resources ... A discussion of the use of technology in this research is what we will do in this section.
Capture a broad spectrum of ambient electromagnetic noises for application in measurement instruments or simple evaluation by listening. The complete circuit is given in figure 1.
You've had latency problems with your electronic design, especially if it uses a microcontroller. Did you stop to think if the problem is due to a poorly drawn program, a circuit that does not work, decoupling or even latency? In this article, we will analyze one of the main causes of circuit problems involving processing: latency.
The mysteries of the human mind and even paranormal phenomena can be studied with the help of many types of electronic equipment. In fact, even relaxation and meditation can be studied with the use of simple electronic equipment. The association of brain rhythms, such as alpha, to several phenomena studied with the help of simple electronic circuits can generate very interesting works. In this article, we will talk about the alpha rhythm and some devices which allow its study in a simple way.
With the circuit of figure 1 we obtain a high logic level in the output when we touch with the fingers in sensor X1. The circuit can be powered with voltages from 3 to 15 V and its output can either excite CMOS logic or interfacing circuit with power relays, solenoids and even data acquisition interfaces.
