HDMI slot is not working?

Question by RogerL78    |  last reply

Fix PCI slots?

About 5 years ago when I built my first computer, I made a few mistakes, perhaps the one that is the most crippling is attempting to fit a D-link WiFi PCI card while the machine was plugged in. Caused the PC to shut down instantly after that characteristic pop. :O This has caused the card to die (I thought), and caused the PCI slots on the motherboard to die. Nothing is recognized on those 2 ports. I would like to know if my PCI-e slots are dead, but I do not have any PCI-e cards to test. :-( I accepted this as fact for the longest time. Out of curiosity, I decided to to investigate this further, and rebuilt a 10 year old computer that I was pretty sure has working PCI slots, so I plugged in a 56K modem and the questionable WiFi card, and ran the lspci command on linux, and saw the 56K modem, but not the D-link card. Great, so I've got dial up lol! Anyway, there was a huge low dropout 3.3V, 5A AIC1084-33PM voltage regulator that was easy to probe with a multimeter on the dead D-link card, and I suppose it takes 5V from the PCI port and regulates it to 3.297V measured. Too bad this isn't what had failed. That would have also been an easy fix if that all that was wrong. Now when I move both cards over to my Z77 rig, I notice that there is NO voltage measured across the output of the D link card and ground, indicating pontenially no power to the ports. My guess is that I killed an hair-thin internal trace on the mobo for the power rail, I think this should be an easy fix, if only I knew exactly which pin is what. I do not know the layout of a big PCI bus, or ATX power supply for that matter, and I certainly do NOT want to fry my new (but now old I guess) motherboard! I do however have a motherboard I can cross-reference for pinout. Anyway if I do figure out that the PCI-e slots do actually work, I would like to get a GPU into this rig for general performance improvements, so what <$100 graphics card is recommended?

Slot car Lapcounter/timer

Good morning wise folks, Looking for ideas for a Slot car lap timer. I have a great set up using an old PC,but we are going portable and moving all that stuff is a pain. What would be cool is a stand alone for 3 lanes that could count laps,display lap time and remember fastest lap time. Oh and it needs to cost less than $20 per lane. Have some ideas?

Cheap Slot car track

I LOVE using slot cars. I HATE the price of them. Does anyone know where I can get some cheap slot car track. When I say cheap, I mean less than $60 for a good bit of track. I plan on slowly building up my main straight away(s) to be long so I can test speed. Any site or info would be nice. But' I'm also considering build the track myself. Meaning, I use a router and and a couple pencils and string to build it out of wood. I know it takes time but I'll have 2+ hours a day with nothing to do. Help? Anyone?

add a mini pcie slot in place of expresscard?

Ok, so if we've looked at the pinouts of the expresscard 34/54 slot and the mini pcie slot, we know that: -they both use USB 2.0 -they both use PCIe -they both run on similar voltages so i tried my luck and wired up a mini pcie slot in place of the expresscard slot in my laptop. ive got all the pins wired correctly and all the grounds are grounded, but my wireless adapter card is not recognized. first off, skip all of the "why bother adding a wireless card when you've already got one?" and "this is just a stupid idea" remarks, thats not what im asking. the miniPCI wireless card ive currently got works, but the bandwidth is really limited because its an older technology than mini PCIe. but back to the question at hand. why isnt my mini PCIe card recognized? i have a feeling that it might be the "CP USB" pin on the expresscard slot, which, on the pinout sheet is labeled as "card inserted", but i have no clue what i do with that pin to tell the computer to check for a card. does anyone have any ideas? expresscard pinout: mini PCIe pinout: any help would be greatly appreciated.

Slot car racing - controlling the cars wirelessly

Guys, I and my two boys have a Tomy AFX slot car racing system that we set up and play. We have a load of track so we can set up a long, winding track. The downside though, is that as the speed controllers are connected by a wire, when one of the cars comes off, you have to go over to put it back on the track and one of two things happen; 1) you have to drop the controller, go over to the point where the car comes off, then run back (Me) or 2) run over to where the car has come off, forgetting that the controler is still connected to the track and pull the track apart (the boys) If there was a way of making the controllers wireless, it would be brilliant. It would mean you could stand where you want and not have to waste as much time when recovering your car. As i see it, I would need four independent transmitters, of one channel each. That's about the limit of my knowledge of the wireless bit! The cars get about 22 volts, although clearly the current is not massive. The current controllers are basically a rheastat with a trigger connected to the wiper that contacts the coiled resistive wire. Any of you clever guys out there know of a relativeley cheap and simple way of making this wireless?

Coin Slot to Arduino... Need Help. What to do?

Hey guys, been doing one of the project in instructables w/c is this Interfacing a Coin Slot to a Arduino. Read and done the instructions provided in the project. But there seems to be a problem bec. i can't seem to get the desired output. I have a Coin Slot w/c was already set to 3 different types of coins (P1, P5.00, P10.00)(Philippine Coins) Set it up according to the instructions of the project, "COIN" white wire connected to pin2 (interrupt pin 0) of the arduino, common ground connection of the arduino and the coin slot (12V), and for an easy way to see the output i put up 3 LEDs on pin8, pin9, and pin10. This is the code i used, (modified)(original comments still there) -- const int coinInt = 0; //Attach coinInt to Interrupt Pin 0 (Digital Pin 2). Pin 3 = Interrpt Pin 1. volatile float coinsValue = 0.00; //Set the coinsValue to a Volatile float //Volatile as this variable changes any time the Interrupt is triggered int coinsChange = 0; int OneLed = 8; int FiveLed = 9; int TenLed = 10; //A Coin has been inserted flag void setup() {   pinMode(OneLed, OUTPUT);   pinMode(FiveLed, OUTPUT);   pinMode(TenLed, OUTPUT);   Serial.begin(9600);                 //Start Serial Communication      attachInterrupt(coinInt, coinInserted, RISING);   //If coinInt goes HIGH (a Pulse), call the coinInserted function //An attachInterrupt will always trigger, even if your using delays } void coinInserted()    //The function that is called every time it recieves a pulse {   coinsValue = coinsValue + 1;  //As we set the Pulse to represent 5p or 5c we add this to the coinsValue   coinsChange = 1;                           //Flag that there has been a coin inserted } void loop() {   if(coinsChange == 1)          //Check if a coin has been Inserted   {    if (coinsValue == 1)     {        digitalWrite(OneLed, HIGH);        delay(1000);        digitalWrite(OneLed, LOW);     }     else if (coinsValue == 5)     {        digitalWrite(FiveLed, HIGH);        delay(1000);        digitalWrite(FiveLed, LOW);     }     else if (coinsValue == 10)     {        digitalWrite(TenLed, HIGH);        delay(1000);        digitalWrite(TenLed, LOW);     } //Print the Value of coins inserted   coinsChange = 0;   } } -- Rather than using microsoft express, i wanted to use simple LEDs on pin8, pin9, and pin10 to indicate if the program read the input correctly. after doing the wiring, and coding in the arduino, i tested to see if it would work. NONE of the LEDs light up after inserting coins on the coinslot. Need Help! :X

Slot Load Music CD Player, to retrofit in a 1957 Motorola Radio? Help finding a CD Drive, or get a Laptop Drive to work? Answered

Hello, my Mom has an old 1957 Motorola Radio. The radio has a lot of sentimental value. My Mom keeps it on display and occasionally turns it on to bring back old memories. Unfortunately the radio no longer works, which isn't a big deal to my Mom, as she loves it just as a statue. I had an idea to remove the innards, which can easily be done from the rear of the radio. Now the front of the radio has a slotted grill design, which a CD could easily slide through it, and it would conceal the Drive, keeping the original look of the radio. In short I need any kind of slot loading drive that will play music CDs without the need of a computer. That is the only problem holding me up on this project. I want to install the CD player and connect it to small computer amplified speakers that can all be hidden inside the radio. I can even solder lead wires to the eject, skip, and play buttons. So that I can hide them in the back of the radio, or possible figure out a way to make it remote controllable. Any help on this would be greatly appreciated. Thanks so much, HandyAndy

Can you convert the SD slot into a general purpose I/O port

SD slot general purpose I/O port Hi I posted this in "burning questions", but think this is a better place? Since user ports, inbuilt RS232 and Parallel ports have long gone from PC's, quick simple projects requiring a few lines of I/O are getting more difficult to implement requiring an extra layer of complexity of USB, BUT........ Could the SD card slot offer a solution? It would appear to have a 4 bit mode, 1bit mode and SPI bus as options. Could someone develop a driver and simple hardware to allow some I/O pins to become available again? This would be a fantastic solution to do Outp(100) and Inp(X) type commands again. I certainly do not have any experience of generating the drivers and linking them to VB, VC etc., but I'm sure someone out there could explore this?
