By using light and sound to induce these brain states we are able to gain greater control and efficiency of brain usage. Furthermore, improvements in relaxation, memory, creativity, stress management, sleep disorders, and even ESP(!) can be had by utilizing a brain-wave machine. Commercial brain-wave machines cost hundreds of dollars, but you can

build your own using only a few dollars worth of components. In this document I will walk you through hardware construction and softw1are control of an easy to build brain-wave machine. Disclaimer: I am not an electronics expert or a biofeedback specialist. If you fry your hardware (or your wetw1are) don`t come whining (or drooling) to me. I assume no responsibility for what you do with this information. With simplicity being the goal, brain-wave goggles can be constructed from suitable eyewear, such as safety glasses, and an array of LED`s (Light Emitting Diodes). I`m using the PC`s parallel port to control the flashrate of the LED`s. Audio stimulation can be provided by a stereo and headphones or the PC`s soundcard. I`m using 8 LED`s, one per parallel port data out line. This provides an easy way to control each individual LED allowing for some variations in pattern and intensity. Each lense on the goggles will hold four LED`s in a diamond pattern. The LED`s are powered by the parallel port and controlled via softw1are. 8 LED`s (choose green, yellow, or red LED`s) DB25 pin male parallel port connector (or butcher a printer cable) Goggles (safety glasses or similar eyewear) Wire Glue the LED`s into the holes. Be sure there is room betw1een the LED`s and your face when you are wearing the goggles. Actually, the LED`s fit tightly in 3/16" holes and I didn`t need to use glue. Wire all of the LED`s cathode leads together and...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
