A 3D printable microscope and translation stage
The idea is to build a mechanical tester which uses a welded frame, a number of 3D-printed parts, an arduino, and a few other simple components. We hope to use the tester to test the mechanical properties of 3D printer filament and 3D printed parts.
The Sangaboard is a motor controller for unipolar stepper motors such as the cheap 28BYJ-48 motors. The custom board (v0.3) can be programmed and an Arduino Leonardo in the Arduino IDE. Versions 0.1 and 0.2 were based on an Arduino Nano.
An open source spectroscopic pyrometer which is simple to build and calibrate where it is needed. (Work in Progress)
