Answers to Questions

1) Guide - I am not going to make a step by step guide on how to make something like this. That would take way too long to do because this was a very involved and time consuming project. But I am happy to answer specific questions you have.

2) Pictures - Yes, I will take pictures of the inside so you can see how it all came together. I think that alone will answer most of the questions about how I built this.

3) USB WiFi/Bluetooth - I had to use USB WiFi and Bluetooth adapters because the native adapters are meant to be used with a keyboard. For those of you with a laptop you probably know that there is a hotkey (Fn button plus one of the F buttons) or physical button to turn WiFi/Bluetooth on and off. So when you ditch the keyboard or your case you lose the ability to turn WiFi/Bluetooth on and off. That means that if for some reason your WiFi gets turned off, like if you reinstall Windows, then it is stuck off. Using USB WiFi/Bluetooth allowed my to bypass this issue as I can now turn them on and off without a keyboard. And no, the virtual keyboard cannot be used for the hotkey.

4) Webcam - There is no webcam because I did not have a use for one. In retrospect it would have been relatively easy to put one in, I just never thought about it since I would have no use for it.

5) 15" Touch Screen - I used a 15" touch screen (even though the LCD is 13.4") because it was the only screen I could find that was truly 16:9 and was at least 13.4" in diameter. Most of the widescreen touch screens are 16:10, not 16:9. It does not hurt to have the touch screen larger than the LCD.

6) Mutli-Touch (Capacitive vs Resistive) - I searched for well over a month for a capacitive (multi-touch) screen that was 16:9 and was at least 13.4" in diameter and was not able to find one. That is the only reason that I used a resistive screen. The capacitive screens are more expensive, but I probably would have paid the extra money. That being said, resistive does have the benefit of being able to use a stylus where you usually can't do that with capacitive. Also, with Windows 7 you wouldn't have been able to tell much of a difference with multi-touch as it's uses are very limited. They still need to work on making Windows fully touch capable like a phone OS.

7) Power Button - On the back of the case there is a recessed Macbook Pro power button used to turn it on/off and put it to sleep. At the end of the YouTube video you should be able to see it.

  1. wow great info dude thank you im stating to order these parts cause i already have two 15 inch hp PCs lol one more question, i see that for the accelerometer you use a controller now did you use a program to use the motion for the screen rotation...was it xpadder, or something else thats the only thing left before i start lol

    ow i found this on ebay http://cgi.ebay.com/3M-Capacitive-15-Multi-Touc-h-Screen-USB-Controller-/130393714417?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item1e5c122ef1

    im guessing it would work but your the master lol i need your inputs

  2. Very impressive. Thanks for detailing some of the information from your build. Can you give us a bit more information on the battery pack you were working on and how you were able to extend the life of it? Thanks.

  3. Can you please give the site to shop for captive touch panel? My search for it went sour. I can only find resistive panels.

  4. When you look inside a laptop battery it is made up of lithium ion cells and a controller. I am simply replacing the original cells with much higher capacity cells.

    ReplyDelete
  5. Yes, I used xPadder to do the screen rotation. To be honest I think that screen rotation is more of a gimmick than anything else. Right now I have it turned off because I use the tablet in landscape mode 100% of the time and xPadder can be buggy sometimes.

  6. Can you explain how you built a longer lasting battery? I would like to know how to make the thing last before building it.

    Thanks!

  8. lol i new xPadder was it lol i think pinnacle make a software similar to xPadder and it suppose to be better but i never tried it, well what about this capacitive touch screen http://cgi.ebay.com/3M-Capacitive-15-Multi-Touc-h-Screen-USB-Controller-/130393714417?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item1e5c122ef1

    will it work, i see its capable of 4:3, 16:9 and 16:10. I assume it will work but i just need your inputs on it since you said you where looking for one so reply soon

    im planing on building 2 with and hp dv6000 and a compaq v6000, one with the resistive touch screen in a few weeks and another with the capacitive screen on the ebay link above later on so thats why i want you input, wish me luck

  9. jayune - You need to check the measurements to see if it fits the case you are building. The screen cannot be 4:3, 16:9 and 16:10. It can only be one of those. For my project I had to use 16:9 so that the case bezel was the same size on the sides and top/bottom...because I used a 16:9 LCD. The only way to tell if it will fit is to get out the ruler and do some measuring.

  10. Hey man,

    First off nice work!
    Secondly, I know that you don't want to make a tutorial on how to do this but, could you at least give us your technological background.
    I am just curious to how feasible this project is for something that isn't an expert at electronics. I.E. the amount of soldering you need to do or tools you need in order to fabricate this.
    Any help would be greatly appreciated before I jump in and start building my own later to find that I am in way over my head.

    ReplyDelete
  11. Very nice.

    This motivated me to take apart my 2 broken laptops. Mine is going to be a bit thicker and I'm still looking into different materials for the case. Hoping to be able to extend the cord on the keyboard and include it in the final product with a kickstand.

  12. Really looking forward to the shots of the internal layout and construction. Looks like all yours need is a badge for the back to really make everyone wonder who built it.

  13. Hi there, sorry don't have one of the accounts below.
    I was looking for a diy tablet pc and found yours, gotta say WOW.
    I have a couple of questions to ask about the screen. You wrote you used a 15 inch touch screen panel on the 13 inch screen, did you have to cut it down to fit in your design specs? if so how?
    Also, could you please tell me how accurate a stylus is on your screen? could you use it for drawing charts, graphs and lines.
    Thanks

  14. wait im a bit confused are we talking about the 16:9 so it fit the case or 16:9 in resolution

    ReplyDelete
  15. If I may be so bold.

    The bezel as it were looks large enough to accommodate the 2 inch difference and it would stand to reason that the metal lining of a resistive display is necessary, so no, you should not cut to fit.

    As I have not used this I cannot say from experience but the specs speak well. Your usual 4 wire resistive touch screen will have between 2048 x 2048 and 4096 x 4096 max resolution. The accuracy should be somewhere around 98.5%

    That basically means it should have almost no noticeable deviation from where you are touching the screen with the stylus.

    ReplyDelete
  16. DrCrunk, you are correct on both counts. First, you cannot cut the touchscreen. The wires run along the outside perimeter...so cutting it would cause it to not work. And yes, the resistive screen is very accurate. It may not be as sensitive as the iPad, but it is just as accurate in my opinion.

    ReplyDelete
  17. jayune, 16:9 is the aspect ratio. It means that the length is 1.77 (16/9) times longer than the height. If you are going to use a touchscreen that is larger than you LCD then you want the touchscreen and the LCD to have the same aspect ratio. In my case it was 16:9 because I choose a true widescreen LCD. You want them to have the same ratio because that allows the bezel to be the same size on the sides and top/bottom. If I used a 4:3 touchscreen on the 16:9 LCD it would not cover the sides of the LCD and would extend way to far on the top and bottom.

  18. Slampana, I have a few questions.

    First, when you say you used a 40gb ssd but did not include that in your parts, are you just saying the hard drive that comes with the laptop is fine to use, and the SSD is really an extra cost?

    Second, how did you construct the battery? Did you parallel several laptop batteries or what? If you could post the battery construction, that would be amazing because that seems to be one of the most difficult aspects of the whole project.

    ReplyDelete
  19. I DID include the 40GB SSD in the parts list. I would definitely NOT use the hard disk that comes standard with the X320 because the SSD is substantially faster and is lighter. When using an Atom processor you need to pick up speed anywhere you can.

    For the battery I am just replacing the standard lithium ion polymer cells with much higher capacity ones. The standard battery pack has 4 x 2150mAh cells and I am changing that to 4 x 5000mAh cells.

    ReplyDelete
  20. Can you make a mock up of the parts for the battery system you are using then?

  21. Wow ... is to order one of these for me? Tablet loved this ... Better than IPAD ... If you join a crowd that loves technology, you can earn money because you are very talented ... Congratulations!

  22. thanks for that answer on the last (now obvious stupid)question, I just have one more, the accelerometer link takes you to a wired remote, I assume you stripped that out of the remote, how did you integrate it in the netbook hardware and how did you drive it? did you just use the drivers that came with the unit or find others or windows just find it?
    I am looking at replacing my aging laptop and this is a great idea, and just what I need and a cool project to do in spare time.
    Thanks

  23. Would you consider building one for someone?

  24. Would you consider building one for me? At a fair profit/ptice?

  25. Hi,

    I am looking for partners with significant expertise in hardware and software development and design, web development / design, graphic design, electrical and mechanical engineering, marketing and supply chain management, project management, investors and funders to build the first of its kind multi touch tablet / slate pc made in the middle east and the arab world. I have good exposure on tech related subjects and can partially fund the project, but of course a project of such a magnitude and scale needs much more than this.

    I came across your blog and was wondering if you would like to join? If you are interested please reply back and we will certainly take it from there.

    If it would be too hard for you to list a detailed guide on how you build it for free, would it be fair enough if I offer a certain amount of money in return for you to develop one for me?

    Thank you

  31. Very impressive build... I wondered if you noticed any thermal problems with the processor and screen packed so closely together? Carbon fiber does not conduct heat very well and I did not see any vents in the video.

    ReplyDelete
  32. dude please update with the pictures

    ReplyDelete
  33. one more question did you use all the carbon fiber kit if not on a scale of 1-10 how much is left...cause i see the seller also have a less expensive set

    ReplyDelete
  34. I am, as are many, looking forward to see your other pictures of this wonderful project.

    Please post pictures!!!

  35. Cool tablet. I have been looking into making my own. Then I saw this and it gave me some ideas. I have two quick questions. Is it possible to make one with any laptop like a Vaio Laptop with the same concept? And also would you still need a wireless adapter if it has an on/off switch for wi-fi built in? Thanks and great job.

    ReplyDelete
  36. Hoping to still see the pictures....

  37. You stated that the touch screen was larger than the LCD panel. I'm guessing that the top cover overlaps the touch screen slightly to cover the excess touch screen? Does that interfere with the touch screen’s ability to read a user's input?

    ReplyDelete
  38. how did you make the carbon fiber case?
    did you just cover the whole thing with carbon fiber or did you build a metal case or what?
    i am planning to make one with a second hand laptop.

    ReplyDelete
  39. Never mind I read an older post saying you build it from scratch

  40. I am coming in late here, but you might want to get yourself a Resistive microcontroler from EETI. their hardware allows for Resistive Multi-touch. And their US supplier is interlogicindustries.com I will be building a tablet with a similar setup soon, and i have been toying around with this hardware. You may find it useful for your CarbonTablet.

    ReplyDelete
  41. Great job!
    Few questions though.
    Could you state the outer and inner dimension of you casings? Width, breadth and heights?
    Top cover has a edge on it, reaching down into the touch panel.
    How tall is that edge?
    What about moulds?
    Did you create one from fibre glass, or did you make the casing directly over foam/wood?
    Brgds from Europe.

    ReplyDelete
  42. Where else could I buy a touch screen display kit thats the right size? I've looked for one thats 15" widescreen and couldnt find it, I also looked for a laptop to fit a 17" touchscreen but they were all too thick. I can still make it with the 17" screen but I'd rather not have 2 inches of space at the edges of the screen.

    ReplyDelete
  43. Got the laptop, took it apart, cut off the camera on it, and now when I turn it on it just shows a white screen. Any ideas please email me: beagleboy@stny.rr.com

    ReplyDelete
  44. Still going to post up internal photos?

    I'm curious at how you did the casing and mounted everything inside without wasting space.

    Also, would you know a source for a wacom tablet screen that would work? I see this as a larger HP TC1100 and it is exactly what I need for note taking. Thanks.

  45. dude, this is getting ridiculous! Please. It has been two months since you told us that you would put pictures up!!! Please, I implore you!

  46. Hi

    I have started a projekt like yours, based on a Lenovo. I have calle it a Oepad in danish (Øpad).
    Here comes the question. how do I get the multi tough to work in Windows 7? Have you installed a different driver than the one that was delivered with the touch display? Please comment, because this problem is the last problem of my projekt.

  48. Did you consider looking for capacitive screens from digi-key. They have a huge selection.

    ReplyDelete
  49. Seems that you have dropped out of the earth! I am also in the process of creating one of these but I don't know electronics enough to finish my project and without your input I can't finish it!

    ReplyDelete
  50. Are you going to post those internal pictures please?

    ReplyDelete
  51. Just to let everyone know I'm in the process of creating one myself and will credit Slampana for the idea and will be doing a full write up for it - hopefully will be done in the next month as the case should be ready within a week or so as long as I get the time to do it.

    @Iversen you can't make it multitouch with the panel resistive one he recommended.

    ReplyDelete
  52. Thinking of buying a dell xt cheap on ebay and removing internals and screen to make tablet with the same carbon fibre construction. Wouldnt this be an easy workaround for an already capacitive touch and digitized display.

    ReplyDelete
  53. @slampana i was thinking of making a touch screen but instead of carbon fibre i want allumium do you know any way fo doing this and can you show the inside of the tablet?

  54. How the battery was made so it could be recharged, and have a power input to charge it? How did you do it?

    What is the accelerometer?
    how did you manage to cool the components?
