Paper ROM and balsa wood airplane

Customer Mike Kohn recently wrote to us about two of his projects that use Pololu parts:

This paper disk is marked with black and white patterns spread across four distinct rings and can store a total of 16 bytes of data. Mike decodes the data with one of our QTR-1RC reflectance sensors. Read more about “PAPER-ROM”…

This balsa wood airplane uses an ATtiny85 to interpret signals from a Syma S107 helicopter remote controller, and it uses our 5:1 micro metal gearmotor HP to spin its propeller. Read more about this airplane project…

Mike has documented many of his other software and 小泽玛利亚av projects on his web site.
