Using a 3.5 tt screen to display speed from a laser chrono set up

Timing a school project - my CO2 powered car (like this www.pitsco.com/Technology/Dragsters ) I have written a code (well..copied and edited) that will measure a drop in reading on a LDR from a laser as my dragster moves through the speed trap beam, starts a timer and then stops time when a second laser is crossed 100mm away. The code calculates the speed (average) over the 100mm. I am using 2 analog inputs for the LDRs to read from. Works well using the Print Monitor. I would like to place this onto a track and have a tft screen display out the speed but are having trouble working out how to do this. Any help would be great. I have purchased the following equipment: 2.4inch TFT and a 3.5inch TFT. A Uno, Mega and Due boards. My preference is to use a Uno board and the 3.5 screen which plugs straight into the uno. Both fit straight onto the Uno without any wiring. Only problem is there is only 1 analogue channel left when the TFT shield is on for the uno. Can I use one of the TFT pins for my 2nd LDR input? I have been looking at writing code to make a simple 2 line read out - "Dragster Speed is...   XXX KPH". Current code (which prints to a serial monitor currently) below. Would love to know how to make this print out on a 2.4 or 3.5 inch screen. I have attached pictures of my 'basic' set up. int firstsens = 4; int secondsens = 5; unsigned long time, time2; float kph, elap; int val; int val2; void setup() { Serial.begin(9600); pinMode (firstsens, INPUT); pinMode (secondsens, INPUT); } void loop() { Serial.println("Waiting for Co2 car to launch...."); val = analogRead(firstsens); val2 = analogRead(secondsens); while (val > 200) {   val = analogRead(firstsens); } while (val <= 200) { time = micros(); val = analogRead(firstsens); } while (val2 > 200) {   val2 = analogRead(secondsens); } while (val2 <= 200) { time2 = micros(); val2 = analogRead(secondsens); } elap = time2 - time; kph = (elap*1000)*60*60; Serial.print(kph ); Serial.println (" kph"); }

What can I do with a scavenged 9" TFT panel?

Over the last several years I have been through three different pairs of portable DVD players.  Since they don't work anymore, I yanked the displays from them.   What can I build with these bad boys?  Is there any way to use them without the controllers from the players?  If not, where can I get a controller?

Handheld Monitor (HDMI / VGA)

I work as a field technician for an IT company and 90% of the time, the servers on customer sites do not have monitors plugged into them. This normally results in me having to scour the site for a spare monitor, or having to bring a laptop along just to remote desktop onto the computer that is sat in front of me! I would love to make a small pocket sized monitor that accepts VGA and HDMI connections. It doesnt need to have any intelligence or OS or anything like that, which is where I am becoming confused... I am really new to the whole arduino / rPi scene and I have no idea if either of these would even be the right option for this kind of thing! I do know that the rPi has a 7" TFT and a VGA module available (along with the on board HDMI connector) so I'm thinking this is the way to go regardless. Any ideas?

arduino TFT LCD-2000-7775

I heard some persons said arduino LCD is the same as LED we usually use the same, try to use LCD this time to do a screen , it is very nice , I really like and the price is also cheaper than the LED , more surprising is that it can also add their own memory card to increase capacity.

use an old Nokia 6265 QVGA TFT screen with PC via USB

Hey guys, I have an old nokia 6265 which i don't use anymore. I was just wondering if it was possible to interface the screen of this mobile with a PC via USB and use it as a secondary display. I got the idea from mimo monitors . So if you guys could guide me in the right direction, I would be very grateful. Thanks a lot in advance to all those who reply.

Nintendo DS TFT LCD Display mod's etc...

This is my first post here, though i have been visiting instructables for quite a while now. Anyway, straight to the point. I have been searching the web for LCD controllers and drivers for the better part of a year now. My hope was to find some web source that might give me some insight on how to reuse an old, but still functional, Nintendo DS TFT LCD display. My efforts thus far have been fruitless. I was hoping that someone with greater knowledge of LCD's and or LCD controllers might post an instructable on Finding/Building/Using a LCD controller. My ultimate goal here is to use the top LCD from the DS as a Heads Up Display/Widget Display for my PC. Hopefully connected via USB. Additionally, my dream would be to have a custom built tablet of sorts that uses the bottom LCD/Touch screen to control widgets and/or (insert media player of choice) via the touch screen. I know this is a rather daunting task, but really all i am hoping for is a little more information from those in the instructables community who have more knowledge on the subject than i do. Info on the LCD TFT LCD Display Manufacturer: Sharp or Hitachi (i'm not sure) Size: 3-Inch Resolution: 256 x 192

Awesome Idea for a Hack but need LCD know how.

Hello there Everyone! I am trying to Do a project where I can use Small LCD screens (perferably a CVS disposable camera 1.4" TFT screen) The problem is I'm not quite sure how to go about hooking them up to a RCA, or S-video input. My whole project hinges upon me getting a good LCD or OLED monitor as they need to be fairly high quality. I cannot seem to find many small LCD or OLED suppliers out there so I am hoping this can be done with the disposible. I would also like to ask if anyone does have information on where to buy small, detailed LCDs that can receive RCA. I considered using a cell phone screen but it seems that you need to break down an analog RCA input and digitize it to be viewed on the screen, something that needs a beefy micro controller and programing knowhow, of which i have neither. Please lend a hand, and you may see my first instructable, of something rather awesome.

LCD tv to computer monitor?

I have a Lenox brand 7" wide TFT LCD color TV model TFT730, it's not much good to me as all of our TV signals are now digital and this unit has an analog tuner. Would it be possible to convert this to a computer monitor? I'm pretty good with a soldering iron, I just need some help with connections and if required, some sort of interface circuit? Any assistance would be appreciated

Arduino: HELP: How to perform action if two rfid tag UIDs have been detected?

I'm using an rfid-rc522 and I want to print to the serial a string of text if two rfid tags have been read in a given time period. Essentially this: 1. First tag is read (print to serial: Tag 1 has been read) 2. Wait 2 seconds 3. Second tag is read (print to serial: Tag 2 has been read) 4. Print to serial: Tag 1 and Tag 2 has been read) 5. Bonus: Keep this state - and then when a button is pressed (print to serial: Tag 1 and Tag 2 are finished) I know how to read the UID and print to the serial if one is read. Thank you so much for your help, it's greatly appreciated. Here is my code so far: #include     // Core graphics library #include // Hardware-specific library #include #include // For the breakout, you can use any 2 or 3 pins // These pins will also work for the 1.8" TFT shield #define sclk 4  // SainSmart: SCL #define mosi 5  // SainSmart: SDA #define cs   6  // SainSmart: CS #define dc   7  // SainSmart: RS/DC #define rst  8  // SainSmart: RES Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst); #define SS_PIN 10 #define RST_PIN 9 MFRC522 mfrc522(SS_PIN, RST_PIN); float p = 3.1415926; void setup(void) {   Serial.begin(9600);   SPI.begin();   Serial.print("Starting cornhole leaderboard...");   mfrc522.PCD_Init(); // Init MFRC522 card   Serial.println("Scan PICC to see UID and type...");   // Use this initializer if you're using a 1.8" TFT   tft.initR(INITR_BLACKTAB);   // initialize a ST7735S chip, black tab   // Use this initializer (uncomment) if you're using a 1.44" TFT   //tft.initR(INITR_144GREENTAB);   // initialize a ST7735S chip, black tab   Serial.println("Initialized");   uint16_t time = millis();   tft.fillScreen(ST7735_BLACK);   time = millis() - time;   Serial.println(time, DEC);   // large block of text   tft.fillScreen(ST7735_BLACK); } void loop() {   // Look for new cards     if ( ! mfrc522.PICC_IsNewCardPresent()) {         return;     }     // Select one of the cards     if ( ! mfrc522.PICC_ReadCardSerial()) {         return;     }     if (mfrc522.uid.uidByte[0] == 0xA4 &&        mfrc522.uid.uidByte[1] == 0xB8 &&        mfrc522.uid.uidByte[2] == 0xB8 &&        mfrc522.uid.uidByte[3] == 0x96) {           Serial.println("Nate has checked in to the game.");           tft.fillScreen(ST7735_BLUE);           tft.setTextSize(2);           tft.setCursor(0, 0);           tft.setTextColor(ST7735_YELLOW);           tft.print("Nate ");           tft.setTextColor(ST7735_WHITE);           tft.println("has checked in ");           tft.setTextSize(2);           tft.println("to the game.");           delay(2000);           tft.fillScreen(ST7735_BLACK);     }     if (mfrc522.uid.uidByte[0] == 0x03 &&        mfrc522.uid.uidByte[1] == 0xFD &&        mfrc522.uid.uidByte[2] == 0xBC &&        mfrc522.uid.uidByte[3] == 0x02) {           Serial.println("Ted has checked in to the game.");           tft.fillScreen(ST7735_RED);           tft.setTextSize(2);           tft.setCursor(0, 0);           tft.setTextColor(ST7735_CYAN);           tft.print("Ted ");           tft.setTextColor(ST7735_WHITE);           tft.println("has checked in ");           tft.setTextSize(2);           tft.println("to the game.");           delay(2000);           tft.fillScreen(ST7735_BLACK);     } } Thank you!

Connect laptop LCD panel to non standard output

Hey... I have an old TFT LCD (~10+ years old) on an ancient notebook. It's a color screen, 640x480 resolution. I also have an mp3 player that I don't use too often anymore. I was thinking that I want to rip open the mp3 player and send the video output to the LCD but I'm not really sure how I'd go about doing this. It just seems like an interesting project, and I'm not afraid to learn new things or whatever... I just need some initial steps in the right direction.

Reuse laptop screen

Hi I had the greates luck finding an old laptop screen in a dumpster at school (they're currently changing computers, dumping the old ones). When I got home I also found a Video to VGA converter, which made me think - can I somehow connect these two into a working screen for  let's say an old nintendo? Either that or I go back to find a compatible motherboard and videocard and rewire it somehow - but it most rather not. So, any ideas for how to make it work as a screen? :) Fact:  - IBM 12,1" TFT screen branded M360 - Konig Video to VGA converter Sorry for the bad images, Ipads camera kina sucks :)

Arduino Code Modification Help (Change of Display Type Used)

This is my first post, so I hope I'm doing this correctly. For reference, I'm new to Arduino, and with no experience with code. I want to try and do a battery tester with an Uno, as seen here (http://denishennessy.com/2012/04/08/measuring-battery-capacity-with-an-arduino/). I'm trying to follow the instructions given, and use the code (https://github.com/dhennessy/BatteryCapacityTester/blob/master/BatteryTester/BatteryTester.ino) that the author has provided. However, due to lack of availability of parts, I don't have a temperature sensor, and instead of the 16x2 LCD screen, I have an Adafruit 1.8' TFT shield. So my query is, how can I modify the code such that it works on this type of display? Again, the code is from (https://github.com/dhennessy/BatteryCapacityTester/blob/master/BatteryTester/BatteryTester.ino), and I have not directly copied it in the post so that it is easier to read. Any help on this would be greatly appreciated.

DIY projector using phone LCD screen.

Hello every body. My first post on these forums, and here goes. I have been looking into projectors and considering the cheaper route of building my own. As I want the projector to be HD and small at the same time, I figured one of the newer phone screens would be suitable (which I have located a reseller of). I do not have any particular screens in mind. To get to the point though, are there any controllers out there that would allow me to connect a screen with dvi / hdmi? As with larger tft panels where you can buy a kit, or such as the device used to bridge the LVDS to hdmi connectors (one example here). I have been unsuccessful in my search for these so far. I assume that most of the screens use different connectors rather than a common standard data connector, which could hinder this. Thanks for your time.

How can I use my old laptop monitor as a screen for my computer (in car) ???

I'm rebuilding and upgrading my old laptop into a 'carputer', I removed the screen as a whole unit, however, i'm fairly adept with car mods and I believe I could adapt the centre console to take the 14" screen as opposed to a costly new 7 or 8" alternative. Electrickery is, alas, a weakness of mine, theres a very short lead coming from the screen, how would I extend it or change to a dvi or vga or summat??? Also the enclosure (standard screen off laptop) is quite bulky, what can I damage by taking the screen housing apart, whats in there... *carries on asking questions in a similar vein, getting more garbled and confused by the second*.....Any help would be greatly appreciated, as there are squirrels holding me hostage and they have guns and...BANG...."squeak, we told you not to say anything, squeak"........."Ah, nuts. I shot the hostage. (nuts, geddit?! sorry :-l)"......

Help with JARVIS-like Smart Home

Hey guys, I am planning to do a project with Smart Home theme. I would like to create JARVIS-like application, which would be able to recognize my voice and then do appropriate action. Example: Temperature Sensor Me: "Jarvis, Show Temperature" Jarvis: -"Temperature displayed sir" I am planning to buy a very cheap Tablet, on which I would like to write an Android Application, which would create "jarvis" and other activities. For example, if I say "Show Temperature" the activity would pop up, where the temperature will be displayed. I will messure temperature with a Thermometer (DS1280 most probably). And I'd like to use a Bluetooth module to communicate Wireless with them. Temp. Sensor -------- > Arduino board ------------> Tablet All of the above are on different locations. I need help with this project, so if anyone could do an instructable on how to do this - would be really awesome! What do I need ? - Temp. Sensor - Bluetooth Module - Arduino Mega - Speech regonition software (BitVoicer probably) - anything else? Also, is the TFT display (http://www.geeetech.com/wiki/index.php/3.2TFT_LCD) good enough to replace the Tablet ?  Meaning, can I write such an Application to this display ? Thanks, David

Embedded video solutions

I'm working on a project that requires the playing of short videos based on some physical conditions. The microcontroller and more general electronic end of stuff I'm fine with. What I haven't yet figured out is the mechanics of the video player mechanism. I want to use digital video stored on removable media (preferably CF or similar memory card storage). The videos will have no sound, be black & white, and probably low resolution (640x480 being the max size). I had originally planned to use an embedded linux system (gumstix verdex or some such thing) hooked to a TFT display. With some software running on the computer, it shouldn't be hard to control with serial communication. However, I'm not sure how well (if at all) mplayer would run on the Verdex. Also, if there's a cheaper solution I'd rather take that. I guess this post is to see what my options are. I know there are mp3 decoders on a chip (like the STA013) that produce output that you feed more or less directly into a DAC. Is there such a thing as a hardware mpeg video decoder (or divx, or quicktime, or avi, or whatever?) If something like that existed, I could connect the CF reader straight through my uC to the hardware decoder and pipe it out directly. Either to LCD or CRT (depending on which signal is easier). So, does this exist? Is it feasible? Thanks,

Making a Laser Cutter, but I need some help!

If there is one thing I do enjoy about making stuff, its when im making it out of cardboard. I wanna make better stuff out of this material, but my patience and skill with an Exact-o knife tend to lack or screw up when im trying to get dead on accurate cuts with large sections of cardboard. So if i'm gonna make some really good stuff i can be more than proud of, I figure i'll need a laser cutter. Ultimately I'm  wanting to build a laser cutter that can: -cut paper, cardstock, cardboard, and fabric without setting it on fire -about a 2 foot square or 2*3 foot rectangular cutting bed -parts that won't cost me more than $100 each i know its possible to build a laser cutter with DVD/CD parts, amongst other things. And i do have one Raspberry Pi Model B board, 1 Arduino Uno and Mega boards, along with 1 Seeeduino: Motor, Relay, Ethernet, TFT Touch, and SD Card Shields. I'm still waiting for my Arduberry to come in the mail, but that's all the major components I have. I do have the necessary tools, soldering and desoldering irons, and a multimeter. Now all i need are the parts and programming skills. I am more than willing to learn Arduino and/or Raspbian languages, and i have ways of getting the parts i'll need, but I have no idea where to begin on the CNC aspect. Can anyone recommend some good resources or parts for what i'm trying to build? I'm not asking for someone to build it for me, i'm just asking for some guidance on this project.

Hi ALL! Please help me to find the bug! Yesterday I did the new instalation of the MPLAB X  last version v3.45 after deleting the old. I did the following tutorial to find bugs in the compilation and chip injection: https://www.youtube.com/watch?v=mUofSucHx_E The problem apear when I try to inject the software in the chip with the PICKIT3 when before nevar did so new problem. Today I reinstall all the software again two times and nothing pass than the same error. Script aded here of the only both files. Thank you in advance.

Arduino heating controller: solar panel, oil burner, stove. NEED HELP AND ADVICE

HI this is my first time with arduino and electronics so please be forgiving.i want to make a controller for my home heating system and if it possible be able to control (change temp. setting, see statistic, etc. by phone - Bluetooth).so, i have three source of heat: solar panels (water), oil burner, wet stove. first part of plan is to connect all electrical components correctly (to make sure nothing blowup), second step is the program. third connect controller with phone by android or have a option to send sms to turn on/off oil burner.let's startthe heating system should looks like that (photo attach)please don't focus on the plumbing (that's only sketch), electronic and programing is more important.program (second step) should do:1. if T5 >T2 pomp P2 work 2. if T3>55'C , P3 work but only if O1 is switch off (automatically P1 and M1 is off, because they will be connect directly to O1 power) 3. option to on/off O1 by click on the phone (or by modul GSM in the future e.g sim800L) 4. additionally options 2 and 3 they are conditioned by other sub-option of 5 zones (where hot waterwill flow, so what will be heat): a)olny hot water in the tank- M3 open, b)only underfoor h.- M2 open, c)only radiators- M4 open, d) all heating, no tank- M2 i M3 open, e) all M2 M3 M4 open. so, before turn on O1 start making fire T3, one of the zone have to be pre-sellect.also if T1 >60st.C (and O1 and P3 are off), P4 will turn on (dump extra hot water to underfloor h.).that's all, nothing more .... but it's to much complicate for me right now. :smiley-confuse: and third part: all should be controll by simple phone app (android) e.g. turn on/off oil burner (maybe timer), change temp. in tank, change zone, see statistics etc.thera are elements what i have already- arduino nano-logging data module-relay 8 ports-bluetooth modul At-09, ble-4.0-extension board nano v3.0- temp. sensors DS18B20 i connect everything by all info what i've found in internet. also i tried to do simulation in THINKERCAD but many of my elements are not exist in the program, stiil no win. i didnt want to connect power just in case of blow off :o this is what i already found online:http://www.reuk.co.uk/wordpress/arduino-solar-water-heating-pump-controller-design-and-code/https://thesolaruniverse.wordpress.com/2016/11/21/monitoring-temperatures-in-floor-heating-loops-with-an-arduino-with-data-display-on-a-3-5-tft-screen/http://house4u.com.ua/articles/solar-controller/en/part11.phphttps://www.instructables.com/id/2nd-Gen-Arduino-Hot-Water-Solar-Collector-Controll/https://forum.arduino.cc/index.php?topic=70048.0and about bluetoothhttps://arduino.stackexchange.com/questions/19517/hc-05-bluetooth-module-inq-command-doesnt-worki only showing the links to proof my hour's spend in google.i think first two are the best.so i put together all what i found and this is my first program:const int TANKSENSORT1 = A0;

// still system have to be sure that O1 or stove P3 not working. // if one of those is on (O1 or P3) 'heat dumping' options cant start// still missing: // bluetooth modul // or logging data modul (statistics) // before heating will be on one of the zones have to be setup.(and save) // 'life' option for changing the zones M2, M3, M4 } delay(250); }and i stuck again.i'm looking for advise about proper electronic setup and program the arduino. i believe there are many people like me looking for help, so this post will have a bigger impact.regards

Tracking down the speed problems on a laptop.

I've copied the conversation here so we could remove the information from the original instructable's comments.  I figure this would also be of some interest to other forum viewers who may have similar problems, or may be able to chip in. The long and short of it is, 92033 (Ed) has a refurbished laptop that takes literal hours to run a YouTube video on.  I suspect that it's due to a bottleneck with his internet connection.  Here's the conversation thus far: ---------------------------------------------------------------- 92033 (Ed): Thank you kindly for your prompt reply...appreciate it very much. I came across this site by accident in searching for something else and now I'm 'hooked' on it. :) So far I've read over 400 archived posts (whew)...as well as looking at the videos. The videos are somewhat of a problem because this new laptop only has 512 mg memory...LOOOOOng time to load. For example...to watch a SLOW 5-minute You Tube video takes 5-1/2 HOURS to load...keeps showing a couple words at a time...need to get two new memory chips to upgrade to 2gb. Thanks again...Take care. ---------------------------------------------------------------- eddems: I think you're basic download speed is killing ya, not the laptop. check you're speed at Internetfrog.com, if you see the link near the bottom for the old test, run it, I like it's graph of upload and download speed much better. ---------------------------------------------------------------- 92033: Thanks much. I'll check it out. I ordered a 1gb SDRAM Memory chip which just arrived yesterday. Hope this speeds things up a bit. ---------------------------------------------------------------- harley_rly: i hear u man, my computer is hopped up, but i live out in the sticks and have dialup...i only get 24kbps at most :( ---------------------------------------------------------------- 92033: Maybe there's hope for 'us' yet. :-) I phoned Tiger Direct to see cost of an upgrading memory chip to go from 512mg to 1-1/2gb. The guy I talked to suggested I get "PC TUNEUP 2.0" which bypasses the Windows Operating System (I'm using Windows XP Pro) and speeds up the system. I gave it a try and ordered the CD (cost $39.98 - $44.77 postpaid). It hasn't arrived yet but will let you know if it helps as he claims it will. He said that if I just ordered a 1gb memory chip my system wouldn't notice much improvement as it is, but this CD should do the trick. THEN...when I DO order the Memory chip(s) to get total of 2gb my system should zip through like a rocket with the CD just ordered. I'll let you know when I get the CD and about the results. Just hope I haven't thrown forty-five bucks to the wind. Thanks for the contact...appreciate hearing from you. TAKE CARE. ~ ED ---------------------------------------------------------------- Javin007: PC Tune-Up "bypasses the Windows Operating System?" This guy fed you a load of crap. (I work on computers for a living.) PC Tune-Up does nothing more than clean up registries, defragment harddrives (if your OS even needs it, some don't) and keeps drivers up to date (which you could do manually.) That guy's an idiot, or just a liar. Could be both. Unless you were buying PC Tuneup 2.0 from Tiger Direct, in which case we can add "sleazy salesman" to that. What are the specs of the laptop? Go to Start/Run and type in DXDIAG. This will give you a quick snapshot of the specs. Specifically, I'm curious as to the processor speed/type. For a 5 1/2 hour "load" you're more likely looking at network slowdown issues (although 512 megs for XP is WAYYYY too little. I HATE when they put PCs together like that). The RAM upgrade will show significant speed increases, but no improvement with YouTube videos or other downloads. I'm glad to see you are returning the CD. ---------------------------------------------------------------- 92033: Thanks much for your input...appreciate it very much. I checked the DXDIAG as you recommended. Here's the info on it: IBM ThinPad Laptop PC. Model # 23738TU. Intel Premium M 1.70GHZ. 512mb SDRAM Memory chip.Page File- 351mb used,513 mb available. Direct Version-Directx 9.00 (4.09.0000.0904). 512 mb SDRAM-Actual 212 Ram. AVAST Anti-Virus. MS Windows XP-PRO.. Dialup Speed-40kbps. PC2700 SDRAM 512mb Memory Chip installed. I ordered 1bb memory chip which arrived yesterday. Now I have to figure out HOW to remove the bottom of this laptop to install it...lotta small screws on it. :-) Oh, total memory shows 32mb. I don't know if this means much to you. I note your comment that the added RAM memory WONT (?) speed up loading YouTube videos? Is that correct? If so, why not? Thanks again. Take care. ~ ED ---------------------------------------------------------------- Javin007: :) At the risk of boring too many people, here's how memory in a PC works: You have two kinds of memory: RAM, and Hard Drive (technically there's three, as there's also onboard video RAM on video cards, but this is primarily used for 3D video game textures, so can be mostly ignored.) Your harddrive's read/write speed is determined by the type of harddrive it is (most are SATA now) and the rotation speed (most are 7200 RPM, though the specs for your system say yours is only 5400 RPM, but there are 10, 15, and even 20K rpm models out there that are exponentially more expensive.) No matter what, harddrive memory will always be degrees slower than RAM. RAM on the other hand is a small chunk of memory that is "temporary" memory, but very fast. Its speed is determined by the type of RAM (DDR2 being the current common one for notebooks, though DDR3 is available with some motherboards (you can ignore this, though, as you can only handle 2 gigs max of DDR with your system). The motherboard will determine the limits for the RAM that can be installed.) When running *ANYTHING* on your computer, and I mean ANYTHING, it must first be loaded into RAM to be accessed by the CPU. The computer doesn't directly access the harddrive. So this means when your operating system is loaded (Windows XP) the entirety of all running processes for the OS have to be loaded into RAM. Now, Microsoft claims that Windows XP only requires a minimum of 64 megs of RAM, but recommends 128 megs. I challenge you to find me a Windows XP system that only uses 128 megs out of the box. It's not atypical for an XP system to chew through all 512 megs of your RAM, leaving no RAM available for other applications. (Interestingly, the default setup for your laptop is only 256 megs of RAM, yet yours is reporting 512.) What happens when there's no RAM left? The system has to then start trading things into what is called "Virtual Memory." VM is nothing more than a file on the harddrive that will temporarily hold information that SHOULD be in RAM, so the RAM can load more info. For instance, say you have a process that's using RAM, but you want to watch your YouTube video. As the video is ready to play, the system will take the other process's data that's in RAM, write it to the harddrive, load your video into RAM in its place, play a portion of it, write the video to the harddrive, load the data for the process to RAM, let it run for a split second (so it doesn't lock up), write it back to the harddrive, load your video into RAM and play a short clip, etc. etc. etc. The result of low RAM on your system is that applications will open slowly (seconds or minutes, instead of instantly or a few seconds) and they will seem slow to respond, will stutter, etc. With enough RAM, your system can freely open as much as it needs into RAM, and ignore the virtual memory and all the slowdowns that it causes. Now, all of this being said, NO lack of RAM will cause a streaming video to take 5 1/2 hours to play. This is 100% going to be related to your downspeed. (Go to www.speedtest.net and post your results.) RAM slowdowns tend to be most noticeable when shutting down, or starting up your computer, apps will open a little more slowly, they will be slower to respond to button clicks, and video will be very choppy. Anything that is causing a YouTube video to take HOURS will be due to the system simply waiting to get the video in the first place. RAM wouldn't slow down the receiving of the video, but it would cause the video to play weird once it's downloaded. So, all this being said, here's the summary: Your system has a 1.7 Ghz processor, and your RAM is most likely 333 Mhz DDR. If you bump your memory up to a gig, you should see a pretty significant improvement in that your computer will, overall, just "feel" faster. It'll be more responsive, and working with large documents will be many, many times faster. This won't, however, affect your YouTube experience (unless you were getting jittery video often, not the same as "buffering" video.) If you see "buffering" for a long time, your internet connection is your bottleneck. A test on www.SpeedTest.net will likely confirm this. However, if you get decent numbers on SpeedTest, then we could have something more sinister going on, though I suspect you'll find your numbers well below the 1 mbps rate. This brings us to actually changing the RAM. I've been out of the PC hardware realm (professional programmer now) for a few years, and was unable to find a manual for your particular model. However, if memory serves, this image should be a fairly accurate representation of the underside of your system: http://www.javin-inc.com/temp/thinkpad.JPG Don't quote me, but I BELIEVE the red circle will indicate the only screw you will need to remove to access the RAM. There should also be a small clip holding the RAM in place that you'll want to pinch to get the RAM out, and make sure that the new RAM snaps into place. (Sometimes you'll have additional empty RAM beds, and you can just put your RAM in there and end up with 1.5 gigs, but I suspect you'll have two 256 gig chips in there.) ---------------------------------------------------------------- 92033: Phew. Thanks again for your most indepth educational lesson. I appreciate all your help more than you realize. I attempted to answer this last night, typing in more than twice the amount of text as your to me, then suddenly realized there was a glitch and I was on another page...lost it all into the ionisphere. :-( Rather than try to retype all I wrote, I shut 'r down and went to sleep. Now I'm trying to recall all I wrote last night but failed to get mailed. I'm not a traditional typist, rather a one-finger bloke so you can understand the frustration there. I do, however, type at a reasonably good speed. With that said, let's continue. I went to search for Configuration of this IBM Laptop ThinkPad 23738TU and am copy and pasting it here.

I'll ATTEMP to try again later. So please don't reply yet as you need to read my discoveries in changing the RAM chip. Meanwhile, thanks again...take care. ~ ED ******************************************************************************* TRY #3...I'm Back :-) Your diagram showing where the RAM chip is located was right on. Thanks. Here's my DISCOVERY :-( The RAM chip installed was NOT a 512mg...but only a 256mg chip. The ads ans specs say it's a 512mg...NOT SO. I was lied to by either the manufacturer or refurbishing company who removed the original 512 chip and reinstalled a 256 chip. I was lied to by the Tiger Direct guy on the phone. There are NOT two chip slots...only one. So I now have a useless removed 256mb RAM chip. Replaced with the 1gb RAM chip I just installed. So instead of having 1-1/2 gb RAM, I only have 1gb. Here's the crux. To. go to 2gb RAM I'd need to buy a full 2gb RAM CHIP and discard the 1gb for which I just paid $39.99 ($45.00 with s/h). This means another output of almost a hundred dollars plus the $45.00 just wasted because they wont accept return once the sealed chip plastic was opened...even though I had no idea there was only ONE SLOT in this PC instead of TWO like the Tiger Guy said. Now...crux #2...this new 1gb RAM does nothing more to increase speed. I just watched a 2.01 MINUTE YouTube video which took a HALF HOUR to load, so I threw the money away for nothing, eh? There is no noticeable change except the 'speed' shows it now as 41.2 kbps instead of 40 kbps. Okay...now HOW do I get to speed this thing up to normal viewing in real time? I also saw an ad for 4bg RAM Gateway laptop with 120gb hard drive for $404.99 which is all suped-up with everything. I had to upgrade a LOT since I got this only four months ago...taking over a hundred hours to load it, like Internet Explorer 5 to 6 and then to 8 and now to 9. I'm using AVAST Anti-Virus, after trying for 23 hours to get ADVAR, then find out it didn't load because of problem on the servor's end. Added Firefox and upgraded twice. Loaded MS Protection but it created more problems so I deleted it...now with AVAST which I like. Soooo...I've literally spent over 200 hours to get this thng where it's at now, plus the wasted money for the upgraded RAM chip.and I still don't have increased speed. HOW do I get it? IF the processor has to be changed does this mean I have to gut the thing and install a new motherboard? If so, what kind of money cost are we talking here? I bought this four months ago as a refurbished unit only because I was able to get it on payments of only $25.00 a month. If I had to wait to get $400.00 cash I'd never have it. :-) Okay...that's it for the moment. Thanks much again for your help offering and detailed instructions...appreciate it more than you realize. Best Wishes And God's Blessings To You And Yours In Everything Always. Most Respectfully... ~ ED  ---------------------------------------------------------------- Javin007: Well, let's start with the RAM. If you're running windows XP, you can assume all the extra processes (virus scanners, and whatnot) will be eating up about 512 megs of the RAM. First thing to do is check DXDIAG again (start/run) and verify that it's now reporting the correct amount of RAM. (Don't be surprised if it's like 9 hundred something megs or slightly more. It won't report 1024 or 1 gig.) This being said, that will leave you with the other 512 for your applications. This box won't be running the latest and greatest 3D games, but I suspect it was never intended to. If the heaviest hitter you'll have running is along the lines of photoshop, the 1 gig of RAM you have now should be plenty sufficient. I wouldn't worry about getting 2 gigs. Not for this rig, anyway. Also, Avast is a great (and free) virus protection, every bit as good as Symantec's Norton, so good choice there. If your youtube videos are choking out, we need to start by verifying that it's an actual speed throttling problem. Go to www.SpeedTest.net and run the speed test. Come back with the results.
