Prototype Lego Sound Brick
A fun BrickLink purchase :)
The external board is wired straight to the internal board. It plays the "doorbell then dog bark" sound from the brick in set 5771 - Hillside House.
Searching the number on the chip (39VF020) reveals it's a simple flash memory chip.
The board (AMA9AA) brings up pages from a Chinese company, Alpha Microelectronics, thatseems to specialize in voice/sound synthesizing hardware. There are references to software called EZSpeech and FlashWriter. There are download links for the software on their website, but they are password protected.
Oh well. I never truly thought I could program my own sound bricks. I bought this as a novelty - and I think it will remain a novelty :)
