Plf laser plumb bob11/24/2023 Laser levels can do everything a spirit or bubble level can do and much more by projecting a laser beam of light across an entire room or job site to provide a point of reference for projects. The best self-leveling laser level can make all the difference and be easy to use.

Check out the build video after the break. Power comes from a 500mAh battery, and all the electronics are situated inside of an attractive hat. The hardware is about as simple as it gets - an Adafruit Feather nRF52 Bluefruit controls a pair of NeoPixel rings, one for each half of the translucent 3D-printed plumb bob. made this Bluetooth-controlled plumb bob as part of their Sims Halloween costume, but we think it has real day-to-day value as this pandemic wears on, either as a mood ring or a portable free/busy indicator. It would make working from home go a lot more smoothly, for instance. While there are a lot of objects from the Sims that we wish were real, we probably wish more than anything that everyone had a mood indicator hovering above their heads at all times. Such a thing would be a great addition to the safety tips in ’s guide to designing a safe laser cutter.Ĭontinue reading “Beam Dump Makes Sure Your Laser Path Is Safely Terminated” → Posted in Laser Hacks Tagged beam dump, laser, optics, plumb bob, reflecor, safety, termination Hats off to for an instructive video and a build that’s cheap and easy enough that nobody using lasers has any excuse for not having a beam dump. His experiments are now much cleaner with all that scattered laser light contained, and the work area is much safer. tested this with lasers of various powers and wavelengths, and the beam dump did a great job of safely catching the beam. In use, laser light entering the hole in the beam dump is reflected off the surface of the plumb bob and absorbed by the aluminum walls. The inside and the outside of the tube and the plumb bob are painted with high-temperature matte black paint before everything is buttoned up. The plumb bob gets mounted to one of the end caps so that its tip points directly at a hole drilled in the center of the other end cap. His version has but a few simple parts: a section of extruded aluminum tubing, a couple of plastic end caps, and a conical metal plumb bob. To avoid that painful fate, high-power laser fan undertook building a beam dump, which is a safe place to aim a laser beam in an experimental setup. But somehow lasers don’t seem to earn the same healthy fear, which is strange considering permanent blindness can await those who make a mistake lasting mere fractions of a second. Between hot things, sharp things, and spinny things, there’s more than enough danger in the average hacker’s shop to maim and mutilate anyone who fails to respect their power.
