Car anti theft wireless alarm - This FM radio-controlled antift alarm
can be used with any vehicle having 6to 12-volt DC supply system. The mini VHF,
FM transmitter is fitted in vehicle at night when it is parked in
car porch or car park. The receiver unit with CXA1019, a single IC-based FM
radio module, which is freely available in market at reasonable rate, is
kept inside. Receiver is.... [Radioland.nt.au] |

Circuit Detects Current Pulses - 01/06/94 EDN-Design Ideas....The
pulse detector provides a visible indication of positive and negative current
pulses. The pulses amplitudes can vary from20 to150 mA. The pulses durations can
range from10 to40 msec, and their repetition rate can span40 to180
pulses/minute.... [Design Idea by Richard McGillivray, Grey Bruce Regional
Health Centre, Owen Sound, Ontario, Canada] |

Crystal Radio - This is a generic circuit, the first true radio receiver in
history. Description: Crystal radio requires no power supply to operate because it uses
energy from the signals it receives. Performance is like one should expect poor.
Nevertheless, .…. (added 10/05) |

Crystal radio with Amplifier - An improved crystal radio with a two-stage audio
amplifier. The 2N3904 (or any other general-purpose NPN) acts as a preamplifier while the
LM386 boosts the signal high enough to drive low impedance Walkman headphones or perhaps
even a small speaker. (added 10/05) |

Dual Mode Superhet/Direct Conversion AM receiver for 181.818 kHz Lowfer ATtiny2313,
AT90S2313 - This is a description of an experimental AM receiver for VLF. It is
crystal controlled to receive 181.818 kHz (more or less) and operates as either a single
conversion superhetrodyne or a direct conversion receiver. The bandwidths are expected to
be 15 Hz to 3.5 kHz in superhet mode and 15 Hz to 10 kHz in the direct conversion mode.
Operation is from a singler.... |
