hi Rzwill you be stocking the rus-04 rgb utrasonic module or similar in your webshop? like the one in your instagram video for Nybble. as this would be much better than the current method of diy'ing the rgb led to the sensor ports.
you have a similar rgb ultrasonic module fitted in a Nybble head in your collection.
