Hey MU5ICI4N, I am glad that you got your light to work. Great job!
Got it working- it was just my batteries that were the problem! Thanks again!
i wanted to do this for a science fair project. i already have a built glider and i wanted to know how what solar panels, what motor should i use and if i need to place the panels under the monicoat because i dont want to open up my planes wing
also the power point is broken
i think he just meant the auto pilot part

jeffmazter,Thanks for responding! 1) I'm actually using three different batteries wired in series to power the driver- one 3.75 V 32650 Lithium Ion battery; one 1.5 V D Cell Alkaline Battery; and one 3 V Lithium watch battery. (Long story short- I meant to order two 32650 batteries but only ordered one, so the Alkaline battery and Watch battery are providing the needed voltage boost until the new 32650 arrives.)When I tested the battery pack with a multimeter, it read around 8.25 Volts. I believe that should be enough for the driver, as on the website it says it accepts from 5.5 - 15 Volts. 2) Thanks for that helpful link! I actually tested the current that the Driver was outputting to the LED, and it looks to be around 0.2 Amps, which seems like it would correspond to the Low-Power mode. 3) I tested all of the electrical connections with the resistance setting on my multimeter, and everything seems to check out4) I emailed kaidomain... hopefully they'll get back to me!Here is a link to a video I took of the blinking pattern: https://streamable.com/aaqrHere's a few images of my project- I'm building a Bike Light out of parts for Mag-Lite flashlights, and right now I'm just trying to make sure that all of the LED parts work before permanently installing everything. The pictures are of my battery pack made from the barrel of an old maglite, and a multimeter measure of the batteries voltage.Thanks again! :DMU5ICI4N
Jeffmazter406,So, I got the Driver and XM-L LED, but I seem to be having a problem. I can't switch out of Low Mode! Every time I wore my LED up, it remains on low mode and blinks every 5 seconds or so. I believe that this low-power-blinking is supposed to be for when the driver overheats, but obviously that can't be happening! Any idea how to fix this? Thanks.
Sorry you are having these troubles - I've had faulty drivers in the past before...but before we do that, lets troubleshoot each thing and see if we can determine what is at fault. Oftentimes, the drivers are programmed to flash when the battery is low. The Lithium batteries you are using (18650 or (R)CR123A) should be at 4.20V charged. Depending on how it is programmed, anything below 3.60 volts may cause it to start flashing. 1) Battery - What batteries are you using and are they charged? Verify with a multi-meter. 2) Measure the current the driver is putting through the emitter - use this tutorial: http://www.lygte-info.dk/info/Measurement%20UK.htm...3) Check all your solder joints...you could have a cold joint somewhere and that's what's making your driver act up. 4) Maybe it is the driver this is faulty...sometimes that happens - email the manufacturer - they may reply, they may not. Feel free to add a few images of your progress to this comment thread - I'd like to see your project. Best of luck.
thanks for your advice...i would look into it...i have another project to do could u help me in that.....? what about solar plane...? i m working on in but i am having a problem in solar panels....i am not having an idea about what type of panels should i use...n what about its balancing ...how could i make it balanced...when i simple panels on it i got a little balancing problem...i could'nt figer it out....could u help me...n thanks again for your advice
Nice project!! I'm just trying to make that ..I wanted to know how many solar panels are needed and what type of panels are needed and how about the pololu 12v stepup regulator should I use that ...r something else that helps me in this project .so that plane flys for more that the normal battery flying time.
When I replied to your question previously, my idea of the solar laser ground station was purely based on my imagination - it turns out that the technology is already available although I am unsure if you would be able to access that technology: https://en.wikipedia.org/wiki/Lockheed_Martin_Stalker
That is a great question. I am not really sure myself - my initial thoughts are that rotor powered aircraft would require a lot more power than a fixed wing aircraft because the rotors/propellers are the only source of lift and it only creates that when spinning at a certain RPM. Feel free to ask around on other forums, but the best way I can think of to provide charge through a completely solar powered system is if you either 1) Tether your quadcopter to the ground and have a thin wire transmitting the power to the aircraft - the ground station would have a large solar array capable of collecting the required amount of energy for your quadcopter or 2) have a solar ground station that converts the solar power into a infrared laser beam that is shone at the flying quadcopter which has a receiver on it. Here's where I came up with that idea from: http://www.popsci.com/technology/article/2011-06/satellites-could-gather-energy-sun-and-beam-it-down-earthWith both of my ideas, your quadcopter would be limited in terms of range and the cost to build the ground station and create all this other stuff I just mentioned would certainly be out of your budget requirements. If you want to move forward with any of this, let me know and we can throw some more ideas together. Is what I just mentioned practical? Maybe. Consider your POU (philosophy of use) and then determine what your best way is to proceed is. Let me know if you have any other questions or if you'd like to develop this concept further. Best of luck.
can u help in making a solar power quadcopter....is it possible to make it n not use other source to charge it,to provide it power for flight....n how can we get control on its wait to make it efficient?
OK, Thanks! I'm thinking of using your mod for a high-powered bike light I'm building :)
To switch modes, depress the switch and release - this particular light I built has a reverse clicky switch so I could switch modes with the light already on (light press on the switch without turning it on.) With a forward clicky switch, I would have to switch modes when the light is off (light click on the switch without turning it to constant on by fully activating the switch). This particular LED Driver switches modes based on a timer inside, so when it detects a switch cycle (on/off), it is programmed to go into the next mode.
Great instructable! Does anybody know how one would switch "modes" (low, medium, Hugh) with this LED driver?

Awsome idea!!! Totally going to do this!
