Give the little witches and warlocks a real trick when they come clamoring for treats on Halloween with this doorbell-activated soundtrack. All that's required to build this spooky sound generator is a moderate hack of a cassette player, which involves opening the case and rewiring the motor for remote control, and rewiring of your doorbell circuit. Add a simple, roof-mounted speaker, and you'll have the little darlings scattering in every direction at the first blood-curdling scream.
R4 10 ohm resistor, rating appropriate for Cue Channel output (needed if the Cue Channel amplifier has an output transformer); Stereo tape player or tape deck and amplifier configured for electrical remote control (see instructions); Continuous-loop tape cassette (TDK EC-3M or similar). EC-3M is a 3-minute loop. One vendor informs me that TDK is the only current maker of loop cassettes and this is the shortest loop they make.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
