I built Memcards to help people learn. If you want to give it a shot, link’s here: https://www.memcards.net Today we're going to MacGyver ourselves a Roland Drum Trigger using an Ikea Cork Pan Holder, a Pizeo, some wire, a mouse pad and a jack plug.
Ironically this is about a dollar worth of hardware and it works just as awesome as the same as the $200 roland pads.
You can find the pre-wired piezo sensors i used here: http://s.click.aliexpress.com/e/ctgJeX6u
