The magnetic wire recorder, ancestor to the tape recorder, had undergone great development during World War II. By the late 1940s, wire recorders were available in consumer equipment.
Paris Hilton’s hijacked phone notes, hot pics and movies, and celebrity contact info got her unwanted and undeserved notoriety. The incident also brought broad visibility to a blossoming dilemma: like computer data, our increasingly computer-like mobile phones’ contents can be hacked.
Check inductors quickly with a PIC-based meter that also measures frequency.
I have been a fan of MIDI (Musical Instrument Digital Interface) since the 1980s. The idea of controlling musical instruments from a computer has always seemed cool to me.
USB Interface for Under $20.00
Last month, we assembled and tested our Ultimate Utility Meter (UUM). This month, I will show you how to operate the UUM.

A BS2px ADC Trick and a BSI Controller Treat
The BS2px is the latest edition to the BASIC Stamp microcontroller line. In addition to increased speed, the BS2px adds two new commands that give the programmer access to features available in the core SX microcontroller: CONFIGPIN and COMPARE.

Focus On The Flash (Atmel AT49LV1025)
Integrating large FLASH and SRAM into microcontroller designs has become a must-know technique with the advent of microcontroller-based LAN devices. Sometimes an EEPROM just isn’t enough to hold all of those web pages you want to serve from your little PIC-based or AVR-based web server. If you’re collecting data, a large FLASH part is nice in that you can store away those accumulated readings and retrieve them intact, even if the batteries go bye-bye on your microcontroller-based data collection
