1980's Toy Robot - Guitar Amplifier Conversion

[mattoverse]

This first video is a quick demo of 9volt LM386 guitar amplifier I built into a 1980's Toy Robot.  I etched the board etc.. Both internal speaker and external speaker options are demonstrated.

This next one is a quick demo of the sound effects mechanism that was inside of this toy robot.  When I first opened it up it wasn't working, and I couldn't figure out how it had produced sound that I remembered from when I had it as a kid.  Turns out there is quite literally a little mini record player inside of this playing a little plastic record.  Pretty wild.

I had no clue how it produced sound when I opened up, actually made the discovery of a little motor spinning a record when trying to get an old Knight Rider Car Toy to work after finding a bunch of childhood toys at my parents house.  It would be amazing if anyone knew how to produce little plastic records like that with your own sounds, samples etc..  I'm sure there is an easy way to do it with a chip or whatever, but the fact that its actually created mechanically is pretty cool.

No, thought I remembered it lighting up in some way, but nothing in there besides the little record player contraption when I took it apart.

a 3d printer could knock out a few disks. how to program the disks, tho?

I wonder if there is some sort of software that translates audio to groove depth etc.. that you could use in the 3d printing cad program?
