    Thank you! This video is the first one that straight on explains why there is a need for current limiting. Its the led itself that draws the current in amounts that could be way beyond its handling capabilities. Nothing really to do with the device powering it up. Rarely people say more that it just needs current limiting so it doesnt burn out, not the reason behind it.

    Hi. I need to make a light source for a fiber optic cable headlamp. I bought an XHP 70 (Chinese from eBay), but with it's own driver it only delivers 5.2v instead of 6v. And it hasn't enough light outsource compared to good quality lamps with the "same" LED. Where can I find a really good quality XHP 70.2 or comparable one.? Not a COB type

    Haha please dont put that on a bike there is such thing as *too* bright bike lights. Especially when you're somewhere that has 2 lane bike lanes. Can be blinding.

    Hello my friend, I hope you will accompany me as a friend who needs help. I am writing with a program because English is not very good. I hope you have given me bad advice and counsel about the plant growth lamp. Of course, I know the efficiency is somewhat windy. I know that the full spectrum plant growth lamp or purple cover has all the color spectrum that the plant needs, but I want you to help me prepare a plant growth panel for marijuana. Three hundred and fifty is good for me. I wanted you to help me decide what kind of LED to get, which is suitable, and the type of color combination that will be installed on the panel. How to place it and the number of colors it needs. And I want to make the cooling device and the panel and everything I need by hand because I do not have access and it is a crime in my country. I hope you can help me. Thank you very much for providing a growth panel for marijuana. It has a suitable and excellent use for the plant so that I can be suitable for the period that I am by the plant. I can get a little more or less the necessary color for the plant, I am really thankful and I will never forget your kindness.♥️♥️♥️♥️

    I would suggest adding a tiny drop of flux before soldering the LED to the wire.

    i got a very small 3W led and had a heatsink on to small.went bigger , bigger still then jumped to 10x10x10 but still getting to hot.judging by that led and the size i need mine to be 40z40x10 at least

    It is remarkable to see how the LED has evolved from replacements for incandescent and neon indicator lamps, to serious lighting. I never expected to see LED used as replacements of strobes and incandescent beacons on emergency vehicles.

    13:38 Those strips of leds should be in parallel if they are longer and your use case allows. The reasoning behind that is voltage drop. The longer the led strip the more voltage drop you get and the leds will become dimmer the further they are from the power source. The setup pictured by no means requires that, but it's good to know.

    I did a deep dive on diy led walls made from led tape! I was surprised to see the limited options, 1 get a decoder and use dmx or use Arduino to control one strip. Thought of your channel and that you might find it interesting! I have a feeling you would have a much more creative way to accomplish an led wall with a wide variety of functionality! Anyway thanks for the inspiration!

    a diode, a LED and a solar panel are the same thing you can make a solar panel or a diode glow you can measure a voltage across a LED or a diode when you shine some light on it you can make a LED and a solar panel act as diodes (allow electricity in just one direction)

    Well! You just gave me enough information to turn me into an infrared blasting monster! My huge backyard is pitch black at night as it will stay because of camera-shy neighbors. Now they can stay shy while I can see my whole domain without them seeing a thing. I figure I'll be needing several hundred watts. I'm gonna have fun fun fun until daddy takes the soldering iron away . . . Thanks again and again and again DIY Perks!

    If you go out and buy a LED floodlight it's really easy to see how DIY Perks makes it go from non-affordable to very affordable. I bought a small 30 watt IR light that made the 600 watts I need unaffordable, but with this DIY video that 600 watts now it's very affordable! But if I was to go out and cast my own heatsink and make my own transistors it would become more expensive than buying it completely. So there is a trade-off between buying the product you plugin and enjoy and buying the components and doing your own assembly. This video hits the tradeoff dead on making the do-it-yourself infrared 600 watts LED lights very doable and easy as shone in this video.

    Quick question or suggestion. I would love you to make an episode on turning a car remote into a Bluetooth activated remote control. I would like to invent a device that you can put your car remote into that can press certain buttons on the remote via Bluetooth. This will allow the user to leave the remote device in ones vehicle and use their phone to unlock, start, lock.. Who wouldn't want that. Many auto manufacturers are making this standard but there are millions of cars on the road without this capability. It could be huge!

    Question: I keep running into the problem of, I have a component ( such as a light bulb) that was powered by a 6v battery back of 1.2v bats. But I wish to power this bulb from say, a 12v bat or a 7.2v bat pack, or a 3.7v pack. Do you have any video's on how to conquer this problem ? .

    Hello I'll be thankful if any knowledgeable person help me regarding power supply of my led Cob led which I got is flipflop type and its of 100w and on data sheet it mentioned 3500ma current and 30-34v but problem is I am not finding exact same output driver but someone suggested me to use two 50w and one 12w driver parallely connented (1500ma+1500ma+600ma=3600ma) by doing this it's exceeding 100ma current and even when I test voltage of that driver it show 48v... Will it be safe to power up the led or it'll damage the led? On data sheet it's mentioned Forward current =3500ma Peak forward current (duty 1/10@10ms) =5250ma Anyone please help

    I was searching instructions for a project I wanted to build and lost about 3 days in time searching worthless DIY youtubers. Sir, someone mentioned you in a forum as a great instructor for DIY. The project has already ended with some more additions to the initial plan. I finished my daughters UFO treehouse Thanks to you. We even hang out with my wife when our daughter is at camp for the summer. With your instructions we created a replica of the part of the galaxy we have above our house. And its solar powered. Again Sir, you are the real deal and thank you :) Cheers. P.S. Sorry for any mistakes in syntax or grammar. English isn't my native language.
