iPhone 6 with damaged backlight

I have an iPhone 6 with a backlight problem. The screen turns on with no light (I can barely see whats on the screen with bright light shined on it) but everything else still works on the phone. The touch screen works, apps work, it’s just the screen that’s really dim is what the problem is. Is this a filter that blew or is it the entire system? I have found a nice recorded solution: https://www.youtube.com/watch?v=R8BedLX7JAg but I would like to be sure that this is the correct issue. Anyone perform the repair which is shown on the video?

Looking to reuse old laptop built in speakers

I recently removed the speakers from my old Dell Inspiron 1400. I'm looking for tips on how to make them into a pair of DIY speakers. Do I just connect them to a minijack and it'll work? There are four colored wires coming out from the pair of speakers (red, black, blue and white) and I read about speakers right and left being red and black but I'm unsure about the white and blue. Appreciate any feedback on this =D

1 Button & 6 Neopixel Strips for an Explorers Map

Here is what I am attempting to make.... An interactive display where a user pushes a single button and 1 of the 6 strips lights in a slow sequence, showing the path an explorer took from point a to point b. There are 6 paths, each path will be its own neopixel strip. When the button is pressed a second time, the first strip goes off and the second strip sequentially lights, all the way through the 6 strips, ending at all strips off. I'd like to make the code work so I can use 6 PMW pins as wiring these as one large array is not practical, possible, just not practical. I am using the following: - 1 Arduino Mega 2560, - 1 momentary push button, and - 6 5v neopixel strips (currently with 19 pixels each, end product will be 60 each. - Windows PC and USB to power for testing I am attaching a code that works great with the button pushes for a single strip, and have a different color applied to each "case" so I'd know which one was active. Is a variable for the output pin number IE 3,4,5,6,7,8 the best way, or do I require a different type of condition? Thank you for any help here! Gary // This is a demonstration on how to use an input device to trigger changes on your neo pixels. // You should wire a momentary push button to connect from ground to a digital IO pin.  When you // press the button it will change to a new pixel animation.  Note that you need to press the // button once to start the first animation! #include #define BUTTON_PIN   3    // Digital IO pin connected to the button.  This will be                           // driven with a pull-up resistor so the switch should                           // pull the pin to ground momentarily.  On a high -> low                           // transition the button press logic will execute. #define PIXEL_PIN    6    // Digital IO pin connected to the NeoPixels. #define PIXEL_COUNT 19 // Parameter 1 = number of pixels in strip,  neopixel stick has 8 // Parameter 2 = pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: //   NEO_RGB     Pixels are wired for RGB bitstream //   NEO_GRB     Pixels are wired for GRB bitstream, correct for neopixel stick //   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels) //   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stick Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800); bool oldState = HIGH; int showType = 0; void setup() {   pinMode(BUTTON_PIN, INPUT_PULLUP);   strip.begin();   strip.show(); // Initialize all pixels to 'off' } void loop() {   // Get current button state.   bool newState = digitalRead(BUTTON_PIN);     // Check if state changed from high to low (button press).   if (newState == LOW && oldState == HIGH) {     // Short delay to debounce button.     delay(20);     // Check if button is still low after debounce.     newState = digitalRead(BUTTON_PIN);     if (newState == LOW) {       showType++;       if (showType > 6)         showType=0;       startShow(showType);     }   }   // Set the last button state to the old state.   oldState = newState; } void startShow(int i) {   switch(i){     case 0: colorWipe(strip.Color(0, 0, 0), 0);    // Black/off             break;     case 1: colorWipe(strip.Color(255, 0, 0), 100);  // Red             break;     case 2: colorWipe(strip.Color(0, 255, 0), 100);  // Green             break;     case 3: colorWipe(strip.Color(0, 0, 255), 100);  // Blue             break;     case 4: colorWipe(strip.Color(127,127,127), 100);  // White             break;     case 5: colorWipe(strip.Color(255, 0, 0), 100);  // Red             break;     case 6: colorWipe(strip.Color(0, 0, 255), 100);  // Blue             break;   } } // Fill the dots one after the other with a color void colorWipe(uint32_t c, uint8_t wait) {   for(uint16_t i=0; i       strip.setPixelColor(i, c);       strip.show();       delay(wait);   } }

Building A SHTF Computer Using This Pistol Case, Need some Advice

So some time ago, i was at an Academy store and did an impulse purchase. Spent $50 on this durable, watertight pistol case as seen in the accompanied image. For a few weeks, i have just let it sit in my room and thinking about what to do with it. Then i thought "What about a Portable PC?". So i did some measurements, the interior is roughly 12x9x5 inches in Length, Width, and Depth (if you count the lid's interior). At best i have some components, such as a 10 Inch screen from an old netbook, i already have the controller board to make it a regular monitor for a few purposes. But a few things im not clear on is what components would best fit this case? I know its too small for most motherboards, and im not intending to use a Raspberry Pi or a Linux OS. And i also want to do as little drilling or cutting into the case as possible to retain its moisture resistance. If i had to list any criteria for such a build, there would be: Information Storage Connectivity to Larger Screens (aka stationary "tower") Wifi Capability Emergency Power Source Thats just off the top of my head, tbh. In short, im wanting to make a utilitarian computer that could survive (and possibly thrive) in a disaster situation of non-biblical proportions, all crammed into a case that was meant to hold a handgun. Keep in mind i have little to some electronics experience, but i have built a pc before. So who has any advice or what-have-you to point me in the right direction? (i hope this evolves into something pretty dang good. i do believe its kind of a challenge to pull something like this off, going with a case roughly half the size of your standard PC tower)

How to make voltage rise sharply from 0v to 5V ?

Hello, So i am designing a circuit board using microhard pDDL2450. So after a few trial and contact help from them, I figured out the reason the board didnt work.  The input voltage after pass through a voltage regulator doesnt rise fast enough, hence the chip wont turn on. So the next logical step would be designing an independent add-on circuit that can make the voltage rise faster.  Any idea on how to do that ?

Converting solar LED string lights to a wall wart adaptor.

Hi all I recently picked up some bargain priced solar string lights for room decoration and to provide a low level of light at night, I suffer from Meniere's disease and one of my triggers is moving around in complete darkness, unfortunately I also have problems going from darkness to light so simply turning on a light can also trigger an attack. I've tried all manner of different lighting but most were not suitable for a variety of reasons. A friend who is also a sufferer suggested LED string lights, the kind used at Christmas or to give some decorative lighting in gardens, he has similar problems with light and darkness to me and had been using them for several years he now has LED lights set into coving in every room of his house, I borrowed a loose string set of his he uses on some plants in a small conservatory while he was away on holiday and to use the same words I did to him on his return they were "Bang on perfect" bright enough to be able to move around comfortably (imagine a couple of candles in a bedroom) but not so bright that they keep me awake. I've had solar lights in the past and knew that the bargain price was probably because they had been in storage for some time so was not in the least surprised to find the batteries no longer take a full charge, I swapped out the old batteries for new ones but to be honest I bought them more for their look than the solar capability, I was originally seeking some mains ones but not wishing to have a hundred or more all I could find were solar or battery, I really don't want the hassle or expense of constantly replacing batteries and the solar ones come on automatically at night so it seemed a good compromise, unfortunately I'm still having problems, whether it's an issue of their not getting sufficient charge from the autumn sun to fully charge (the panels are stuck to my windows so are in full sun all day) or simply that the batteries are running down too soon they are just not lasting long enough for me to rely on them. What I would like to do is change the power to a mains wall wart, each string is powered by a singe AA 1.2v 600mAh battery and I'm hoping I can swap this out for a hard wired adaptor of suitable output. I'm not really an electronics/electrics guy, I can build wiring looms for motorcycles OK, I've made some simple additions to the circuits on my electric bike to power an alarm and installed 12v LED car bulbs into its lighting but that is all very simple low voltage stuff, I don't have much experience with converting from battery to mains. My questions are pretty straightforward and I'd like layman's answers, a whole lot of technical chatter about amps living in Ohms and suchlike will get me nowhere, all I want to know is is it a viable option and if possible where I could obtain the necessary adaptors suitable for UK 240v mains electrics online. These are the only tech specs I have on them that seem appropriate to my question are they are Solar Power: 2V 100mA If it's any help these are the lights in question. https://www.amazon.com/Finether-Festival-Celebration-Decoration-Commercial/dp/B01M6CLVQX Thanks in advance for any help ideas and suggestions.

Im planning on building a motorized trailer dolly for my travel trailer, however i want to make a dead mans switch for the trailer brakes.  I was wondering if I took apart an old cordless drill if I could use the trigger as a voltage regulator to regulate the voltage to the trailer brake system.  Without getting into specifics of how it will connect to the regulator, I figure I would have like a bike brake handle that while applied the trailer brakes would be off, but if released that the trailer brakes would be applied incase the trailer started to roll away from you. Any suggestions other than "Go buy a trailer brake controller" would be appreciated! :)

My RGB led uses 3 digital pins with pwm but since i am using an arduino pro micro with 5 pwm pins, I can only use 1 led.

I thought maybe someone on this forum could guide me to install the switch to the circuit board of the garage door. i have also attached some pictures of the garage door circuit and the switch. Thank you for your help

Manipulating temperature in garment steamer

 I have a garment steamer. As a school project, I need to do an innovation where I need to add temperature regulator features. I have read that irons use thermostat to control the temperature, how do i install a thermostat in the steamer or is there other ways to regulate the temperature. By the temperature regulator, i should be able to produce the right amount of steam at the right temperature for each fabric.

Arduino + Stepper

Hi! I have an Arduino nano and a Minebea PM55L stepper motor and I have to connect these two together. I read the Arduino tutorials, and got a ULN2003 chip. The thing I am unsure of is the power supply and which wires of the motor do what or should be connected to what. There's 6 of them and I really don't want to fry anything if at all possible. Could somebody help out, please?

Arduino Mega with Sim900

Recently I bought Sim900a module and Arduino Mega 2560 to run my old code for sending sms and call, but now there is a problem as I am unable to send sms or either call, my code is attached below. #include SoftwareSerial gsm(2,3); void setup() { gsm.begin(9600); // Setting the baud rate of GSM Module Serial.begin(9600); // Setting the baud rate of Serial Monitor (Arduino) delay(100); } void loop() { if (Serial.available()>0) switch(Serial.read()) { case 's': Send(); break; case 'r': Recieve(); break; case 'S': Send(); break; case 'R': Recieve(); break; } if (gsm.available()>0) Serial.write(gsm.read()); } void Send() { Serial.print("Sending"); gsm.println("AT+CMGF=1"); delay(1000); gsm.println("AT+CMGS=\"+xxxxxxxxxxxx\"\r"); // Replace x with mobile number delay(1000); gsm.println("Hello I am GSM modem!!!");// The SMS text you want to send delay(100); gsm.println((char)26); // ASCII code of CTRL+Z delay(1000); } void Recieve() { Serial.print("Receiving"); gsm.println("AT+CNMI=2,2,0,0,0"); // AT Command to receive a live SMS delay(1000); }

LVDS board with raspberry pi

Hi there, I recenlty purchased a M.NT68676.2A LVDS board and connected up to my raspberry pi. All of this is working fine however the setup at the moment looks like frankensteins attempt at a pc, so i was wondering what is the best way to go about building a box to contain my setup, bearing in mind i have no CAd or the like expereince and no access to a 3d printer (no small ask i know) I want the box to be able to support a 15" laptop screen and have the ports accessible on the outside. Look forward to some ideas. Thanks
