Lite3DP 3D Printer: Arduino-based open source MSLA / LCD-SLA resin micro 3D printer kit (schematic, PCB, source code, etc.)

Lite3DP is a micro 3D printer that uses high print quality, virtually silent MSLA technology. It is the first of its kind to be completely Arduino-based, is open source, and comes in an easy-to-assemble kit format. It is a simple machine designed for experimentation to provide an in-depth and complete understanding of its operation. It can be placed on almost any table or in any workshop. MSLA resin 3D printing technology can achieve stunning levels of detail and surface finishes that are far superior to what can be achieved with filament 3D printers – primarily by using screen-cured resins such as LCDs on Lite3DP. Although 3D printers with MSLA technology are already available at similar prices to filament printers, they are closed-source projects that eschew one of the most valuable features of modern 3D printing - accessibility.

NeuroStimDuino: an open source neurostimulator for students, researchers, and enthusiasts interested in neuroscience

Neurostimulation involves the application of short electrical pulses to the surface of the skin to stimulate underlying nerves and muscles. In recent decades, neurostimulation has been used as part of functional electrical stimulation (FES) therapy to help restore movement to muscles in paralyzed limbs in stroke patients and people with spinal cord injuries. While conducting research in areas such as pain relief and sensory feedback, scientists also use neurostimulation to study the effects of electrical current on neurons. Historically, the delivery of neurostimulation has required the purchase of expensive research-grade equipment or costly, time-consuming custom hardware constructs. NeuroStimDuino provides an open source alternative in the form of an Arduino shield.
