WaveDrum External Trigger Modification

[Bogush]

Despite my highly questionable soldering skills I am now the proud owner of a slightly modified wavedrum with an external rim trigger input.

Do you already have glue on piezos ?
not only for extenal triggering from somwhere,
but also directly from the Wavedrum skin.
