Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
Talking Fish Hack -  These items were sold nationally several years ago. The fish would sing, open its mouth, turn its head, and flap its tail. After removing the back panel, all of the existing electronics were removed leaving only the 3 servo motors, speaker and photocell.….) [Luhan Monat - Mesa Arizona]
Talking Frog Box -  This device 'listens' to a conversations and then interjects words and phrases at inappropriate times….(design added 08/08/08) [Luhan Monat - Mesa Arizona]
Talking Morse Code Practice Computer -   [Ken Staton's website]
Talking Phone Dial Monitor -  Speaks the numbers that you dial as you dial your telephone. 5 pages. Not available as a kit of parts. [free schematic from Golab.com]
Talking PIC   Based on SP0256 -  (electronic circuit added 4/05)
Talking Voltmeter -  Ever needed to measure a voltage without taking your eye off something? If so, then this is the project for you! The Orton Talking Voltmeter takes a voltage measurement in the range 0-5 Volts and then reads it out to you to two decimal places (i.e. to 10mV resolution). The design illustrates the use of the 10 bit ADC in the PIC,....(added 04/04/04)

Talking YODA project PIC16C84 -  (electronic circuit added 4/05)
Train Approach Warning Circuit -  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]

Ultrasonic Dog Whistle -  A novel supply voltage monitor which uses a LED to show the status of a power supply. [by Miroslav Adzic - Serbia & Montenegro]
Wave Multiplier for music Synthesizers -  (electronic circuit added 4/05)
WaveSong -  A shareware PC application that generates nature sounds (rain, surf, crickets, thunder, pink noise, white noise) which are relaxing to hear and help mask ambient noise when played through headphones or loudspeakers. Requires Windows 98/95/NT4.0/2000/ME.  Designed by Jim Sells (Sagebrush Systems)  (Circuit design added 03/08)
Weird Sound Generator -  (electronic circuit added 08/08/08)
