Dayton Audio HDN-8 Weatherproof Sound Exciter Transducer DriverUnlike a tactile transducer that delivers 'shake' effects to your listening experience, the HDN 8 Sound Exciter Transducer is a full range, versatile, compact transducer that can excite a surface or structure over a wide bandwidth, enabling the creation of completely hidden audio systems in walls, ceilings, and floors. Its high power handling allows it to produce useful sound levels with a small number of transducers, and its hermetically sealed
there are cut-lines every 1
this module can't do anything
Additional information: The HDN-8 is a transducer that produces sound through resonating surface area
The METRO works great with the Arduino IDE
it can tune into signals from 24MHz to 1850MHz
This programmer works really well for ATmega168 and ATmega328 and should work with all the AVR micros supported by AVRDUDE
Leaving out the extra microcontroller means the price
which works well but is noticable if the LED is moving
