Project Name: Stealth Duck, AKA Super Daffy
The Stealth Duckis a custom designed and built flotational sound effects package built on a remote controllable boat platform and using a duck decoy as above water camoflage. The Stealth Duck will be able to slip into the midsts of hostile flocks of ducks undetected, deliver its auditory payload, and speed away with impunity. The Stealth Duck currently does not have information gathering capabilities, and as such, is intended primarily for delivering propoganda and for the disruption of primary functions, communications, and supply gathering of both foul and humankind. Information gathering capabilites will be incorporated in the Speed Goose, which is not scheduled to begin design and development until the completion of the Stealth Duck project.

On Sept 17, 1998: An SFX storage and playback I.C. was tested in both record and playback modes using a 600 ohm microphone for recording and an 8ohm speaker in series with an 8 ohm resistor to achieve the 16 ohm differential output impedance required by the device. The device is capable of playing at normal audible levels, however the nature of this project will necessitate the development of a higher power output amplifier, which will also allow the use of a single 8 or 4 ohm speaker.
June 16, 1999: Latest releases of sound storage devices have pushed capacity up to 16 minutes and converted from parallel addressing to SPI controller mechanism. Downloading software is 85% complete and I am currently debating whether to make the PC do everything or simply the software by using a serial-in, SPI-out microcontroller on the download board. The desire is to make one board capable of handling all of the various architectures of storage devices, however, this is not a high priority. The software is written to function in Windows 95 or 98.
May 19, 2000: Update on status - A new family of sound storage devices are available now that use SPI bus for control. Z8 micro programmer has been purchased and the micro code has been flowcharted. Main board hardware is approximately 65% designed and PC S/W for loading WAV's to the device has been written, although it will need some minor re-work due to changes in system design. Current plan is that the PC download board can see double duty as the MIST2, which will precede the Duck project. The Duck Project will be a simple evolution, exchanging the PA amplifier of the MIST2 for an FM transmitter and possibly changing the micro to a stripped down playback-only PLD to help reduce current consumption (at a premium due to battery powered environment).
