1000W LED on a Drone [video]
- Numberwang 10y agoI like the videos. Did he ever mention what drone he was using?
- baddox 10y agoYes, at the beginning. http://freeflysystems.com/alta-8 http://freeflysystems.com/alta-8
- Waterluvian 10y agoHe must work for them because this video was half an ad.
- amelius 10y agoWhat is its size and weight? How long does it fly? Edit: I watched the video without sound.
- Someone 10y agoBoth drone and lights last for about 10 minutes, according to the voice on the video (about 35 seconds in)
- mschuster91 10y agoAbout 10min of flight+light time.
- sschueller 10y ago$17k for a drone with 10min flight time? Ok, it can carry up to 20lbs which is quite impressive. [1] [1] http://store.freeflysystems.com/products/freefly-alta8 http://store.freeflysystems.com/products/freefly-alta8
- reustle 10y agoI think the flight time was lower due to the weight of the light and battery array?
- georgeecollins 10y agoBy the way, the flight time to lift ratio of LiIon battery powered drones are one of the reasons I know all those stories about Amazon using drones to deliver are absurd. The drones would have power for two or three deliveries at most. LiIon batteries don't have that long of a lifetime and they are expensive. Not gonna happen with today's technology.
- imaginenore 10y agoDJI Spreading Wings S1000 is $1900, and can carry 15 lbs. https://www.dji.com/spreading-wings-s1000/feature https://www.dji.com/spreading-wings-s1000/feature
- pimlottc 10y agoClearly there was some sort of sponsorship here, would be nice to see it explicitly mentioned though.
- Retric 10y agoIt can do 30 minutes with a 2LB payload., or 15 minutes with 17LB http://freeflysystems.com/alta-8/dependable http://freeflysystems.com/alta-8/dependable. 20LB means both fewer battery's and more work. Also, I think the cost is more from how modular the thing is, it's very much a professional product which limits sales. PS: Looking at lose curves, it should be able to do 1hour with 5lb and significantly more battery's. But you get more total flight time with fewer battery's that your hot swapping.
- raldi 10y agoEven ignoring the inevitable progress of technology, 10min is still plenty of time for a crew with two of these and a stack of spare batteries to have continuous light until the stack runs out. While one is in the air, the other is getting its battery packs swapped out.

- buro9 10y agoOne could use a bicycle lamp easily enough and I suspect it would be smaller and lighter than the DIY setup shown. http://www.lumicycle.com/mountain-bike-lights/summit-range/summit-2016.html http://www.lumicycle.com/mountain-bike-lights/summit-range/s... That lamp is 1,100 lumens on standard high power, lasts over 4 and a half hours at that brightness. And if needed, there is a boost mode that gets you 1,650 lumens but only for a couple of hours. This is for the smallest battery, a 2.6ah that weighs 220gms. And if you're wondering, yes my bicycle has insane lights. 2 of those and then a 605 lumen dynamolamp giving 3,905 lumens on a bicycle. Yes,I chose tight beam and aim at the ground about 10m ahead, unless I leave the city when I put one wide beam lamp on and raise it a little.
- peter_132 10y ago1k lumen need about 10W electricity if produced by white LEDs. This drone has about 50-100k lumen
- buro9 10y agoMy mistake, I autocorrected W to Lumen when I read the headline.
- FoeNyx 10y agoOn a side note, it might not be a good idea to directly glare at powerful LEDs. French Agency for Food, Environmental and Occupational Health & Safety noted [1] some points that might not be photo-biologicaly safe, the main points being: > spectral imbalance (significant proportion of blue light in white LEDs); > high levels of radiance (high brightness density per surface unit emitted by these very small sources) In the french version of their report, they refer to luminance [2] rather than radiance. The spectral imbalance photochemical risk seems linked with cumulative dose of blue light, so there is also a risk with low but long exposure light LED screens. It also perturbs circadian cycle (flux or redshift might help in that case). See also a previous HN discussion about a warning from the American Medical Association about the spectral imbalance in LED streetlights [3]. -- [1] https://www.anses.fr/en/content/led-%E2%80%93-light-emitting-diodes https://www.anses.fr/en/content/led-%E2%80%93-light-emitting...

- juiced 10y agoThis is great for search and rescue.
- robryk 10y agoI expect a drone with a low light and/or thermal camera to be immensely more useful for SAR.
- kevindeasis 10y agoI'm starting to get really intrigued by the idea of programming quadcopters, especially with this demo. I think I could impress the people I am teaching programming with this type of projects. I'd like to learn how to program a quadcopter and be able to fix the hardware just in case something goes wrong. However, my main problem is that I don't know where to start. I do not have a hardware background. Does anyone know some good resource? I'd prefer if it had nothing to do with the scratch language
- voltagex_ 10y agoWhat's your goal? Have a look at ArduPilot. Sidenote: I wonder what the Hello World of drones is.
- kevindeasis 10y agoGoal is to mostly be able to learn how to program the quadcopter. Be able to fix the hardware or the quadcopter if anything goes wrong. Then possibly something one day doing something like this: https://www.youtube.com/watch?v=Gl1xYyGom1g https://www.youtube.com/watch?v=Gl1xYyGom1g https://www.youtube.com/watch?v=QuXp_mnDH6w https://www.youtube.com/watch?v=QuXp_mnDH6w
- asimuvPR 10y agoAnother vote for ardupilot here. Easy hardware because its an arduino, great community and simple to use.
- Noseshine 10y agoArchived but still accessible: https://www.edx.org/course/autonomous-navigation-flying-robots-tumx-autonavx-0 https://www.edx.org/course/autonomous-navigation-flying-robo... > Autonomous Navigation for Flying Robots > You will learn how to infer the position of the quadrotor from its sensor > readings and how to navigate it along a trajectory. It was a good course, offered by the computer vision department of the Technical University of Munich, Germany. Unfortunately, unlike some American universities, TUM has done less than a handful of exploratory online courses ("trauma surgery", posted on Coursera, was really good too) and then stopped, seems like they have neither plan nor vision (pun intended) for online courses.
- gnipgnip 10y agoA Servo ? Some reason for why a relay wasn't used ?
- snovv_crash 10y agoOr even just a FET.
- Raed667 10y agoThe only time I used a servo to flip a switch was because I was too lazy to modify a completed set-up.
- anotheryou 10y agoA shot with fixed aperture turning the light on would have been nice. Preferably with some street light for comparison.
- WhitneyLand 10y agoReally nice project showing a combination of technology and artistry. I wonder if it's the same guy doing the drone customization, and also producing and directing the film.
- givinguflac 10y agoThis is so cool. I would love to see a version of this with the ability to follow you and avoid obstacles on it's own. Basically a kickass outdoor robot flashlight. Probably not possible with current tech, but bonus points if it can perch on a tree or something when you're staying in one area to act as a fixed spotlight.
- Beltiras 10y agoWith the advent of nanowire-in-gel batteries, flight time might increase tenfold.
- deleted 10y ago[deleted]
- spraak 10y agoI think someone seeing this from the ground, not understanding what it is, might think it's a UFO
- alkonaut 10y agoIf you can't identify what the flying object is, doesnt that make it a UFO by definition? ;)
- david-given 10y agoI see UFOs all the time; I should really learn more about ornithology.
- agumonkey 10y agoFox Mulder is all I could hear in my head the whole time.
- ommunist 10y agoBrilliant work, just awesome amount of skill and attitude in action. Mind the app for LED control interface.
- yq 10y agoI have seen RC helicopter powered by 2-stroke gasoline engine. I wonder why there isn't any Drone use that engine, it basically provide more fly time, more lift power and short "charge" hours.
- duskwuff 10y agoBalancing and maneuvering a multirotor requires fast, precise control of power output. It's difficult to get that from a gasoline engine.
- RealityVoid 10y agoSimple, add a variable pitch propeller. There are people that did it.
- photogrammetry 10y agoIf you think adding variable pitch propellers to a multirotor is "simple," you're sorely mistaken :-)
- baddox 10y agoThere's not much point in debating what "simple" means, but it has certainly been done. There are collective pitch multirotors that are mass produced, marketed and sold to recreational customers, and quite stable. Granted, most of these still use electric motors. The point is for 3D flying, not the potential longevity of a combustion engine. The first commercially available one I know of (no longer produced): http://www.curtisyoungblood.com/legacy-product-support-curtis-youngblood/attachment/stingray-500/ http://www.curtisyoungblood.com/legacy-product-support-curti...

- photogrammetry 10y agoHate to say it, but the narrator's sticky, overly glossal voice is painful to listen to.
- joepater 10y agowait, do you mean 1000 lumens?
