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?

320x240 tft screen as computer's monitor?

So, I'm running low on cash but I was thinking about how to make a portable gaming console. I can get old computer for as low as 5$, which solve the problem with emulation. The question is: Can I use 240x320 screen as monitor? All I want is playing MAME, NES, SNES, Gameboy and GBA games on that computer. I have a few of those tft availlable with me right now. Getting an old CRT to plug in is cheap but it's heavy. And if it's not possible, is there any other cheap altenative? I'm apologize for my bad English, I don't come from an English-speaking country.

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?

My question is could the magnets cause any damage to the screen or the electronics of the e-reader? Please don't give me any over analysed answers describing magnetic field strengths I am making a book cover not a hydro electric generator, I don't wish to blinded by science I just need to know if there is a possibility that a couple of 2mm x 20mm hard drive magnets could do any damage.

Help finding a way of controlling an LCD with USB 3.1 Type C?

Hello and thank you for taking the time to check out my problem. Recently my laptop tied, sad story, and I have decided that I would like to pay an homage to its faithful service by turning the LCD display into an external display. I realise that that there are many guides on how to do this, using a controller board that sources an external power supply. However, I would like to use USB type-c to power and deliver the video signal to the display. As the idea is to make it a portable display I don't want to need an extra power supply to power my second display. USB definitely can deliver enough power to the display, but after searching for hours I was not able to find any controller board that has this capability. Either it is difficult to find due to the overwhelming amount of regular controller boards or it does not exist. Surely I cannot be the first person in the world to attempt this, or come across this problem. I hope that maybe any of you might have the knowledge of how to pull this of, or maybe tried it yourself or even better, know of a commercial hardware solution for this.Oh yeah, my panel is a B156HW01 (V3).Cheers and thank you for your time! EDIT:I woke up with the idea of maybe splitting a USB Type C cable to get the power and ground of the usb c and run this into the power port of for example: https://www.amazon.com/Controller-Board-Driver-Panel-B156HW01/dp/B079HPRGS4?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag;=duckduckgo-ffab-20&linkCode;=xm2&camp;=2025&creative;=165953&creativeASIN;=B079HPRGS4 and then plug it into a usb c to DVI adapter. However I do not have enough knowledge of the electronics to tell of this is a really stupid idea of a potential solution.

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.

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.

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 :)

How to fix a Dell 15" LCD monitor?

I have a Dell 15" TFT LCD monitor (E153FP) which appeared to stop working recently. It flickered for a while and then went black. However, when you look close it is displaying the images but not being lit up. Therefore it must be something to do with the backlights. Also, I took it apart and there seemed to be some black dust on the power circuit board. I can't afford a new monitor and can't really afford to take it to a repair shop. So, the question is does anyone know how to fix this problem? I have little to no experience in circuit board electronics but I reckon I would be able to pick it up with a good walkthrough. Thanks for reading my question and hopefully you can answer it! Harry.

Laptop Suggestions?

Recently I graduated high school, and I am now about to be a Freshman in college.  I was wondering if the Instructables Community could be nice enough to suggest a good computer to an incoming Freshman. I will be majoring in Broadcast Telecommunications and Mass Media, with a minor in Computer Science so I am going to need something that can handle video editing and storage pretty well.  Also, I am an avid PC gamer, so something that can handle games like Team Fortress 2 and Borderlands (just to name a few) would be great.   This is what I've been looking at and unless I can get any better suggestions, this is what I will probably get http://www.cdw.com/shop/products/Lenovo-ThinkPad-T420-4178-Core-i5-2520M-2.5-GHz-14in-TFT/2328427.asp    Thanks for helping me out Instructables!

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,

Led Power Supply?

 I am going mad over trying to figure out what power supply I need. I am making an arduino controlled aquarium fixture and plan on using 30x3w leds. From what I understand using resistors could cause fire and I don't want that of course. I like the look of laptop drivers like this one http://www.gapsupply.com/LED-Power-Supply-p/12v-dc-nwp-96w.htm but I cant figure out which one I need. I have seen all the instructables for this and everyone seems to tape 8 meanwell drivers together. I dont want a big bulky ugly mess like that just one power supply to do the job. The smaller and more compact the better. I will be running 2 rows of white on the outside and one row of red in the middle. 10x3w leds per row. each row individually dimmable via ir and tft. here is the led specs. Whites: http://www.ebay.com/itm/390908787444?_trksid=p2059210.m2749.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Forward Voltage: 3.2-3.8V-700MA Luminous flux: 200-230LM Output power: 3w Light Color:  White 6000-6500K View angle: 120-140 LED support:Copper Life time:50000 hours Reds: http://www.ebay.com/itm/310834616296?_trksid=p2059210.m2749.l2649&var;=610229587957&ssPageName;=STRK%3AMEBIDX%3AIT DC Forward Voltage:2.2V~2.8V Forward Current: 600-700mA Output power: 3w Light Color:  White 6000-6500K View angle: 120-140 Any help and ideas is greatly appreciated.

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.

Questions on building a lithium battery pack with pcb?

I have to build a pack to run my portable N64.  I have some experience building with NiMh and NiCad, but I havent built a li-ion yet. Ive done my research but would like some feedback before I start building. Parts 18650's - 3.7V  3600mAh ea 7.4V PCM for 18650 Li-Ion/ LiPo 7.4V Li-ion/LiPo charger at 1.2 Ah Plan Either to build a 2S2P pack or a 2S4P pack.  Currently the N64, 7" TFT LCD, Controller, and Audio amp w/ 2x 8Ohm speakers is consuming just over 1A from what i can tell.  its running off of a perfboard w/ regulator and rail, thats hooked up to a universal transformer that is set to 7.5V  1A.  Everything works but when I turn the volume up it cuts off and then powers back on.  I dont know any other way to find out the over all power consumption.  I cant just look up all the specs because the LCD is from china and i dont have any specs. Anyway, back to my plan.  obviousely I want as much run time as i can get out of it with out compromising weight and space.  all componants of the portable can run off of 7.4V or lower, to include the lcd even though its rated at 12V. it can run as loas 6.5V. I have been debating between the 2S2P which should yeild 7.4V 7.2 Ah, and give me a runtime, some where in the ball park of 4 hours. or a 2S4P which should yield 7.4V 14.4 Ah. It would only be slightly more space and provide approximately 8 Hours+ Thats if I am even calculating everything right Ok, Regardless of whether i run a 2S2P or 2S4P the connections to the Protection Circuit will be the same, Right? Pos --> B+ Neg --> B- + to - ( Between Series connection) --> B1 or BM I understand that Li-Ion are safer when it comes to balancing then LiPo, but is this right?  having 2 parallel cells or 4 parallel cells connected with the only balance connection between the series.  I just want it to be safe. Next  is the charging.  I bought a cheap smart charger for 7.4V 1.2A output.  Will it matter whether i build the 2S2P or 2S4P, or will it work for both.  I know it will obviousely take twice as much time to charge with the bigger pack, but is their a max number of individual cells that a PCB can handle, or does it only matter the overall voltage? I also Included in my diagrahm a setup for a DPDT switch to change between pack powered, wall powered and battery charging.  I want it to have an "ON" and "OFF" setting. while off, pack is disconnected and if wall charger is plugged in, it will charge the pack.  while in the "ON" position, pack will power the device, but if wall charger is plugged in, then it will run off that. Can I even use a wall charger for the Li-Ion pack to power the device, or will it not work.??
