ESP8266 meets the force....
Using the code posted here https://gist.github.com/tagliati/1804108
for the Arduino, with some minor changes it ports easily over to the ESP8266 WIFI ........

Basically it poles one of the GPIO's with a frequency ....leading to overdriving my Bench Amplifier.
...now the fun begins on creating Web enabled music..... and IOT annoying Thingies...
......and in the PipeLine a 3D printed ESP2D2 droid.......
