# LED Ring Light

Designed by [Capable Robot Components](http://capablerobot.com).  Follow us on [Twitter](http://twitter.com/capablerobot) for product announcements and updates.

---

This repository contains schematics, layout, and bill of materials for an [OSHW](https://www.oshwa.org/definition/) microscope LED ring light.  It can be controlled via the Capable Robot [SAMD21 Touch HMI](https://github.com/CapableRobot/SAMD21-Touch-HMI) or any other MCU which has software libraries for the NeoPixel.

The PCB is powered and controlled via a 3.5mm TRS jack (more commonly known as a headphone jack).

The ring light is designed to fit around the end of a [Opti-Tekscope OT-M HDMI Microscope](https://www.amazon.com/Opti-Tekscope-Microscope-1920x1080p-Resolution-Brilliant/dp/B01JKHJRPM), but it may fit around other microscopes with at 35mm diameter body.  The project has a second PCB, which a matched M3 bolt hole pattern, which allows the LED Ring Light PCB to be clamped onto the aluminum structure of the microscope with long M3 bolts.
