Speaker uses dancing ferrofluid to visualize music

A speaker made by artist Dakd Jung, spotted by Gizmodo, visualizes music with ferrofluid, a liquid filled with tiny magnetic particles. The ferrofluid, a viscous black blob, reacts to an electromagnetic device and dances around in sync with the sounds being played.

MOSFETs Drivers and Bootstrap

One of the main differences is their channel type. It could be N or P. The main difference between an N-Channel and a P-Channel MOSFET is that N-Channel usually goes to the ground or negative side of the load, and the P-Channel to the VCC or the positive side and that might result into problems when using them in a circuit.

The encoders - 2500 points per rotation

In a nutshell, an encoder is a sensing device that provides feedback. Encoders convert motion into an electrical signal that can be read by some type of control device in a motion control system, such as a counter or PLC. The encoder sends a feedback signal that can be used to determine position, count, speed, or direction.

CORTINA BLUETOOTH

Desde hace algún tiempo, tuve una cortina de fondo verde en mi taller. A veces lo uso cuando quiero cambiar el fondo de mis videos, porque es muy fácil usar ese efecto. Como lo tenía hasta ahora es muy feo porque está parado ahí en la esquina. Por ahora lo estaba usando en unos rodillos deslizantes y cuando no lo uso, lo pongo a un lado. Eso es feo y desordena la cortina. Por eso hoy pasaré de ese sistema a una cortina automática motorizada con rodillos que subirá y bajará y que se puede controlar con mi smartphone. Podrías comprar ese sistema en AliExpress si quieres, pero yo quería una versión casera. Y esto es muy bueno, ¿verdad? Compartiré con ustedes como siempre, de forma gratuita, las piezas impresas en 3D, el esquema y el código en esta publicación.
