Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the picture below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed.

RingLight with Stand

Originally, this ring came with a dimmer, but it was built into the wall adapter so not very useful for portable projects. This guide on analog RGB LED strip control will show you how to dim a 9V LED - you'll want a microcontroller with a PWM output, and a single N-MOSFETs to control the power

This LED Ring Light is designed for use with microscopes but we kinda like the design and think it could be a really nice LED element for costuming or lighting effects or... something else? Of course you could also just use it as a great addition to your photo and video projects. It's super illuminating with cool, soft, light, perfect for photo studio lighting. We've also seen these used as microscope illuminators for intense, focused, and shadow-free detail work.

Note these are not 'NeoPixel' LED strips, you can turn the entire thing on/off or dim it with a PWM power signal but you cannot turn on individual LEDs.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.

Hook it up with 9V power, and you're one step closer to lights, camera, action! You'll need to provide 9V power, it won't work with 5V for sure. This wall adapter will do the job for when you have an outlet. If you want to power from a USB supply, try this USB-9V booster cable. For DIY connections, check out our 2.1mm male DC plugs.

Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal.

There's also three 'set screw' attachment screws that would normally be used to friction-fit these to a lens or cowl. There's no guarantee of how the screws are offset from the power connection, it seems different on each LED ring.

Feature papers are submitted upon individual invitation or recommendation by the scientific editors and must receive positive feedback from the reviewers.

If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!

Abstract: The successful 2020 launch and 2021 landing of the National Aeronautics and Space Administration’s (NASA) Perseverance Mars rover initiated the first phase of the NASA and European Space Agency (ESA) Mars Sample Return (MSR) campaign. The goal of the MSR campaign is to collect scientifically interesting samples from the Martian surface and return them to Earth for further study in terrestrial laboratories. The MSR campaign consists of three major spacecraft components to accomplish this objective: the Perseverance Mars rover, the Sample Retrieval Lander (SRL) and the Earth Return Orbiter (ERO). Onboard the ERO spacecraft is the Capture, Containment and Return System (CCRS). CCRS will capture, process and return to Earth the samples that have been collected after they are launched into Mars orbit by the Mars Ascent Vehicle (MAV), which is delivered to Mars onboard the SRL. To facilitate the processing of the orbiting sample (OS) via the CCRS, we have designed and developed a vision system to determine the OS capture orientation. The vision system is composed of two cameras sensitive to the visible portion of the electromagnetic spectrum and two illumination modules constructed from broadband light emitting diodes (LED). Vision system laboratory tests and physics-based optical simulations predict CCRS ground processing will be able to correctly identify the OS post-capture orientation using only a single vision system image that is transmitted to Earth from Mars orbit.
