    XL6005 understanding the datasheet

    Hi all, a driver circuit needed for lighting a 30W LED* (one color) - I had a look at the XL6005 datasheet and wanted to make sure I understand it properly based on the following diagram**: 1. To drive the LED with 300mA I should make RS = 0.73 ohm (ILed=0.22/0.73=0.3A) 2. To limit the max...

    Electronics rookie trying to convert broken LED display into skylight

    Hi all New here! I am looking to convert my broken LED display into a skylight, something like DIY Perks youtube videos. I was able to disassemble the display and get the lens layers and broken panel off. But i am unable to figure out exactly how to bypass the signal detection stage of the...

    XML T6 LED DRIVER MODIFICATION

    Good night. I bought this flashlight for my bike: https://www.ebay.es/itm/Luces-Bicicleta-Luz-10000LM-Impermeable-3XT6-LED/292872854958?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 But the light that comes out seems very little to me. I think it has more potential. Could I modify...

    I need help with a LED Organ circuit.

    Hello guys! This is my first post here, so I'm sorry if I break any rules or anything. I'd need some help with an LED Organ circuit. This is the design I came up with: It's just a crossover circuit connected to 3 transistors that are supposed to pull the LED's low. Problem is that it is not...

    Need help powering LED

    so I took the LED strip out of my tv or to be more accurate 3 LED strips (6 bulbs each) I thought if I took a strip down to 4 I could hook it up to 12v power and it would light but I have gotten nothing, anyone willing to help me figure how to power these?

    RGB Led problems

    Hello, Iam still pretty new to electronics this is my first time using a RGB led i plan on each color to be on at one time no mixing colors, the part iam using is a common Anode RGB I planned on using a 5v power source to connect my anode to, the max led ma each color can handle is 20ma which i...

    DIY LED Lamp with mains dimming

    Hi all, I would like to put together an led lamp that can be dimmed with a normal household dimmer switch. I have seen lots of circuit diagrams to show how to add a dimmer into an LED circuit but i can't find anything out there to explain how it can be done based on the supply voltage. I'm...

    Wire Lighting system to bike using 12v

    Building a bike. I want to run the headlight, brake light to brake lever, LED turnsignals and handle bar switch to a rechargeable 12v. No, i dont want to buy a new flywheel and coil system for the motor. I would rather swap out 2 12v and leave the engine alone. So I know little to nothing...

    12V LED Flasher

    Hello everyone, my unlce asked me if I was able to check out a flashing light for construction use ( Klemmfix Horizon 21307) and see whats wrong with because it didn't light up anymore. On further investigation, the batteries seemed to be fine (runs on 12V input) but the bulb (Xenon flashing...

    IR receiver resolder?

    Hello everyone, I have recently bought an GU 5.3 socket 12V RGB LED spot with an IR remote. For my project, I would need the IR receiver to be outside of the lamps housing. Can I simply desolder the IR receiver and resolder it to the circuit board using wires and place it outside of the lamps...

    How to handle multiple LEDs on usb device

    Hi, im curious how to handle ,lets say 20-30, LEDs that could draw max 60mA each on USB device. As i know usb port could deliver about 0.5A and those used in full(white color) draw around 1.2A+ ... This question is about power not how to connect them. What is the trick to use them lets say all...

    Need Help with LED Driver design

    I'm trying to design an LED driver that takes a ground as ON, performs a logical NOT on it, and sends it into an N Channel MOSFET. The MOSFET will give ground to a color channel on an LED strip. LED Strip Driver-schematic.pdf I believe I have taken care of everything, but to be honest, this is...

    Looking for Suggestions on Driving 600+ LEDs in Asymmetric Matrix

    I'm in the process of designing an mono-color LED matrix that is basically in the shape of a horseshoe/rainbow, with the ability to control individual LEDs, preferably with an Arduino, as I'm familiar with them. As of now, due to space constraints, I'm using 0603 LEDs, but that eliminates the...
