KIAP

Is it a kick?  Is it a clap?   Well yes it’s a kiap!

Based on the TR808 kick and clap circuits this is a version using easy to get parts.  This circuit also incorporates the White and Pink noise generators.  The pcb image is 600dpi and reveresed ready for ‘press and peel’.

As I have designed this circuit for single sided etching there are quite a few wire links to add.  So when building this module there are 11 wire links that can be made using resistor leg off cuts.  Here is where to put those wire links.

Short links      (put these in first)                                 Long links (put these in at the end of build)

Here is the populated board.

I have left pads on the board should you wish to add a switch to toggle between white and pink noise.  This can then feed a normalising socket which then feeds the clap noise input.  This will allow any signal to be patched into the claps band pass  and envelope circuits.
