Was a tedious Saturday..then i decide to play with 555 timer chip

I have made something that may be a Class D (not sure)

Not that bad the sound....has very small power...but quality is not that bad....but a lot of adjustments should be made.

I have made also another one...but it is not exactly Class D.

Here you have an update... things are now better

It is evoluting.... it is still a toy...but getting better.

The input amplifier, if you need it, them use it...showing in this schematic, only, the 555 chip and the output...now i have included a filter...waveshape is correct now.... or less wrong.:eek:

You do not know uncle charlie..but things i publish are tested, assembled and operates... they are not simulator stuff...tested...built..listened.

And you can listen..here you have the first one made....now the sound is better:
