Make a Flanagan Neurophone - Like Device with a TL494 | some electronic projects

UPDATE: Try it with NO audio input and the frequency set to 40kHz! That may be all you need to amp up your IQ. More here: http://neurophone.wordpress.com/2014/04/02/a-new-way-to-neurophone/ Also, if you can't afford the $800 Neurophone NF3, there's a $99 Neurophone in the works. . . but it will only ever see the light of day if enough . . ........

Electgpl: Prueba de funcionamiento del TL494 con Pequeña Carga

En esta nota les mostrare el funcionamiento del TL494 con una pequeña carga en modo StepUp Booster, mediante un driver fet realizado con una configuración complementaria de transistores BJT NPN y PNP, excitaremos el gate de un transistor de potencia MOSFET que controlara el switcheo de una bobina de 2A para luego rectificarse y filtrarse.Este proyecto no cuenta con Feedback, es decir, el ciclo de trabajo PWM lo controlamos con un potenciometro de forma independiente de la salida.Para que la tens.......

Electgpl: Prueba de funcionamiento del TL494

Esta sera una prueba de funcionamiento del TL494 de manera que podamos polarizar el mismo de manera simple y obtener una modulación de ancho de pulso en sus salidas desfasadas. También podemos obtener una señal diente de sierra que ya les comentare mas adelante en otros proyectos la utilidad de la misma.El TL494 es un circuito integrado destinado a la modulación de ancho de pulso para fuentes switching.Este posee en su interior todo lo necesario para lograr un control total de la fuente, la frec.......

13.8 V / 15 A from a PC Power Supply

The major disadvantages of usual linear power supplies are high power dissipation, the size and the appropriated weight. When looking for an alternative solution, I decided to use a switch mode power supply (SMPS). The efficiency of such power supplies is around 70 % to 90 % at a power density of 0.2 W / cm?. Because homebrewing was out of the question due to lack of time, I tried the modification of a PC switch mode power supply........
