This makes is difficult for an average person to undertake such a project. So using what was leaned from designing a high precision, computer-controlled spin coater, we came up with an approach which will allow for the building of a high precision spin coater with much less effort than was required previously. Only familiarity with Linux operating system, and basic fabrication skills are needed.
This is accomplish by leveraging a RaspberryPi + PiTFT Touch Screen, USB Stepper Motor Controller, High Speed Stepper Motor, a pair of low-cost CD Cake Boxes, and Java Control Software to tie all the components together. The design archives speeds of 5,000 RPM with +/- 2 rpms resolution, and has a BOM cost of less than $300.
