Cave crabs create cute cacophony

Craft & Design Music

Jimmie P. Rodgers explains his Creepy Cave Crab light/noise synths –

I made these for the Willoughby and Baltic Halloween show at the Charles River Museum of Industry. They use a single Hex Schmitt trigger inverter IC to generate the sound, and two RGB color change LED to generate the lights. I then encased them in friendly plastic, and painted them with silver paint.

Jimmie is also the designer of a new kit available in our Maker Shed –
