more tree printer work
Today we discovered that we can obtain two motorized axis in one ready made assembly. We cannibalized a carousel 5-disc CD player from the late 90’s and found an amazing $5 solution. Since the motors are standard DC, I’ll have to incorporate some type of position sensing – but that my be a great way to avert the impending shortage of i/o pins on the arduino board.
Also, we are going full bore on fund-finding effort. Next application to submit – blackrock foundation – deadline 3/13.
We also talked about a beach robot that makes sand castles by spitting sand and water as it rolls on one axis.
