3 Level Audio Power Indicator - Battery-operated3 LED display that
connect it to loudspeaker output (added 04/02) |
|
Audible Train Approach Warning - This is a circuit that will give
an audible warning that a train is entering a particular section of track.
The detector also has a LED that indicates when a train is entering or
leaving the block. [from Rob Paisley's Model Train web site] |

Canary Sound Effect - Reverse engineered circuit diagram of a
commercial Electronic Bird. This one was built into a plastic
christmas ornament and runs off a 9V battery. Note that L1 is actually just
an audio transformer with an unused secondary winding....[Circuit by Stepan
Novotill] |

Colour Organ - Three Lamp-Channels OutputBuilt-in Electret Microphone
(circuit added 12/2009) |
|
Cricket Chirping Generator - Funny gadget for props and jokes.5, 12V
Battery operation. (circuit added 6/07) |
|

|
Cuckoo sound Generator - This circuit generates a two-tone effect very much
alike the cuckoo sound. It can be used for door-bells or other purposes thanks to a
built-in audio Amplifier and loudspeaker. Used as a sound effect generator it
can be connected to external Amplifiers, tape recorders etc. In this case, the
built-in audio Amplifier and loudspeaker may be omitted and the output taken from C8
and ground.…. |

DMX lighting & special effects - (circuit added 04/05/06) |
|
Dog Whistle - (electronic Circuit diagram added 03/03/03) |
|
Electronic canary - (electronic circuit added 2/07) |
|
Electronic Canary Sound Effect (Stepan Novotill) - Commercial Electronic
Bird. This one was built into a plastic christmas ornament and runs off a 9V
battery. Note that L1 is actually just an audio transformer with an unused secondary
winding… [Reverse engineered schematic by Stepan Novotill] |

Electronic Chime - Scroll Down to find this circuit. This circuit
simulates a chime similar to the sound many cars make when the keys are left in the
ignition. The bottom two gates form a squarewave audio oscillator that drives the base
of the 2N4401, turning it on and off at an audio rate. The top two gates produce a
short low-going pulse about once per second that discharges the 10 uF capacitor
through the diode. The voltage then jumps up and slowly decays....(electronic design

Graphic Equalizer Pro - A shareware graphic equalizer program that operates
in real-time. Can adjust any sound source (such as the CD player) available on the
PC's soundcard mixer menu. See A Quick Guide To Headphone Accessories for tips on
using an equalizer with headphones. Requires Windows 9x/Me/NT/2000/XP. Designed
by ANWIDA Soft (Circuit design added 04/05/06) |
