radio control - Circuitos electrónicos

While the term is used in many different ways, on this blog I would suggest that hobby broadcasting is about trying new ideas and exploring interesting concepts. Unlike community radio, which is focused on the audience, I feel that true hobby broadcasting is mostly about the broadcaster. Trying new frequency bands, using different content delivery modes and exploring little used technologies .......

En esta etiqueta antihurto de una prenda de ropa podemos ver los circuitos que acompañan al pequeño microchip. Esta etiqueta ha sido fabricada por la empresa SML. La antena se comunica por radio con el sistema de control y además proporciona la energía para activar el microchip, de forma que se pueda leer o escribir sobre él. La tecnología de identificación por radiofrecuenci.......

Elektor Electronics 5/98 The history of licence-exempt use of radio transmitters started a few decades ago with the private use of low-power transmitters for radio-con- trolled models. Much later, CB radio in the 27-MHz band was legalised and type-approved radios for this band were freely available. However, the use of type-approved radio-control transmitters as well.......

Introduction How many times you needed some remote control to handle some electric device ? many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared and RF (Radio Frequency). One of the weaks of

A Circuit: Here is a circuit that can be used to control switchable electronic devices. Add some long leads to the PhotOResistor (CdS cell) and mount it pointed at your computer monitor. Use black card or a film cannister to control ambient light falling on the sensor. If you use this circuit to launch a model rocket, you must have a manual switching system built into the circuit and follow all model rocket flying safety procedure.......

Two features of the Arduino make it much easier to prototype embedded microcontroller applications. The first is that you don't need a special programmer like the AVRISP mkII to program the chip. (Don't get me wrong: using a programmer can be really useful, and you need it for certain tasks like burning fuses. But for just getting a program to run, it adds extra hardware that is n.......

or, Bobby Tables from 1938 to 2011 by Travis Goodspeed concerning research performed in collaboration with Sergey Bratus, Ricky Melgares, Rebecca Shapiro, and Ryan Speers. The following technique is a trick that some very good neighbors and I present in Packets in Packets: Orson Welles' In-Band Signaling Attacks for Modern Radios (pdf) at Usenix WOOT 2011. As the title su.......

Published by www.ModemArea.com (Modem Unlocking Website). Aha, at last Now it is to make Usb Mp3 Player at home with Usb Mp3 Player Module. This Module can read MP3 files from a USB thumb drive and play it for you. I Found a compact sized USB Reader circuit, which has a Sleek IR remote control, Comes with small LED Based Display. (LED Based Seven Segment Display). I bought it from a local s.......

The LT3509 is a dual, current mode, step-down switching regulator, with internal power switches each capable of providing 700mA output current. This regulator provides a compact and robust solution for multi-rail systems in harsh environments. It incorporates several protection features including overvoltage lockout and cycle-by-cycle current limit. Thermal shutdown provides additional protection. The loop compensation components and the boost diodes are integrated on-chip. Switching frequency i.......

OSCAR 200SW Transmisor AM 7MHzHace diez años atrás construí un paralelo de cuatro válvulas 6146 en RF moduladas por un push pull paralelo de cuatro válvulas 6DQ6. No pude disfrutar plenamente de ese equipo construido íntegramente en casa. Creo que fue menos de un año en el que cumplió su cometido y luego por múltiples razones lo perdí. En los años posteriores mis tr.......

. Siguiendo cómo realizar páginas embebidas, las cuales interactuen con Arduino, veremos un ejemplo de cómo usar formularios. (Se debe leer primero el siguiente post)Nuestro ejemplo se trata del envio de texto a un display lcd 4x20, a través de internet/local via página web embebida en el router. Para ello, crearemos una página web que contenga un formulario, al cual se enviará la información de 4 controles de tipo INPUT a un script, que sacará dicha información por el puerto serie hac.......
