This is a progress log for my build of a Wav Trigger box.

This is based on the wavtrigger component that accompanies Look Mum No Computer’s design for the Big Button Sequencer - you see it briefly at timestamp 5:40 in the how-to video on that page. I accessed the instructions for this through the Patreon which is paid access. I named it after the picture on the tin.

I have a stereo output running from the 3.5mm socket on the Wavtrigger and out the side of the tin - directly to a little mixer. this is how the jacks and LEDs looked before I attempted adding resistors and wiring.

I’ve picked up a Korg SQ-1 sequencer to tell it how to play, by plugging the CV gates from the sequencer into the CV ins on this unit. Audio then runs out from the wavtriggers on-board speaker port to a speaker.

The wiring looks like this at stage 2:

I think maybe I need to trim the bits sticking out.

The trouble is, the LED on the component is giving me no signs of life. The little button doesn't work (although, the sequencer sends a really faint little clicky pulsy sound in into the inputs, through the wavtrigger and out of the speaker, so something CAN run through it from end to end, and the exterior LED's work). There's a tiny switch that goes RUN/LOAD - that's on 'run'. I'm using a 9V, guitar pedal power supply. I wonder if I can instead use a 5V phone charger, cut the wire and connect its insides to the VIN and GND next to the little card slot. The phone charging unit would then be a very small buffer between my dubious-looking tin can thingo and scary mains electricity, so I hesitate. I've lodged this with the Sparkfun tech support.
