Modding the Asus 701 (Eee) – Bluetooth

Last week I researched how to subvert the Asus 701 (Eee)!

Last year I documented adding internal USB Bluetooth to another sub-notebook…

Now I’ve combined the two – I’ve added internal USB Bluetooth to my Eee without interfering with the built-in wireless, using the empty mini PCIe card slot, or disabling any of the available USB ports :)

First, I stripped the casing and USB connector off a small USB Bluetooth module (Bluetooth 2.0 + EDR):

After soldering 30 ga. flexible insulated wire to the USB Bluetooth module, I wrapped it in Kapton tape:

Then I connected the USB Bluetooth module to a 5V trace (off in standby) and a nearby ground trace – I used the USB signals available on the mini PCIe card slot occupied by the Atheros mini PCIe wireless card:

Finally, I decided to install the USB Bluetooth module in the area between the track pad and the status lights under the palm rest. I picked this location because there’s no shielding over the front edge of the palm rest to interfere with the PCB antenna on the USB Bluetooth module:

The end result in Xandros Linux:

The end result in Windows XP:

Here I have a Bluetooth mouse connected as well as my Sony Ericsson K850i which is being used both as an HSDPA modem over Bluetooth and as the camera taking these pictures:

641 Kbps dpwn and 264 Kbps up – pretty good for an HSDPA modem over Bluetooth, especially indoors, right next to a wireless router:

Just remember, kids… Don’t try this at home!

  1. Now… if we could only add a GPS module in there… :)
    There are new GPS chips coming out, with just a few mm… Could we fit one of those in there as well?
    Sort of these ones:

    And the new 3.5G mobile internet access USB dongles are as small as a USB flash disk… I think we could squeeze in there as well.

    With Mobile Internet connectivity and GPS, the Eee PC would be nearly perfect.

    Now… if we could only fit a 10″ 1024×600 LCD in there…

  2. Just for reference, that uBlox GPS module I was talking about:
    It’s a complete, standalone GPS receiver in just 17 x 22 mm
    (available for under 100 Eur as a sample from UBlox or for 150 Eur as a complete evaluation kit)

  3. Now the real question, if I buy all the parts and fedex it to you, will you make it for me? :D

    Im also thinking this should work on any umpc. Might try both on my q1u.

  8. Shikamjr says:

    Very impressive way to implement bluetooth !
    I’m not sure I’ll perform same thing on my “future” eeePC ;-0

  9. […] Finally, one of the first and fairly easy to do mods for the Eee has come to light.  While this does require some soldiering it isn’t hard or expensive.  All you need is a soldiering iron, a small USB bluetooth dongle and some quality time with your Eee.  I plan on trying this mod out tonight on my Eee and I will be sure to report on its success.  Hopefully this is the first of many such mods for the Eee.  Read  […]

  10. Nicely done, can you post some details about how easy it is to fit into the casing with your mod? Maybe some pictures? :)

  11. Triften says:

    Kwong, It looks like as long as you have some steady hands for the “surgery”, the only part you should practice is the soldering. You’ll still need steady hands judging from the size of the circuitry.

    And, if you open your eee and find that things aren’t like they are in the pictures, it’s okay to bail on the project.

  12. Pete says:

    There are some very small gps units available.
    Although it will need a serial to USB chip and an antenna it’s still probably possible to fit it in the case.

  13. Alex says:

    Good Find Pete I may give it a try!

    Thanks for the article. Of course I have questions.

    Are you connecting to the same USB lines as one of the external ports or is this a spare USB port?
    I’m wondering if this impacts the use of the external USB ports?
    The Mini-PCIe slot; have you tried any cards in there? Especially Flash cards and possibly a cell modem card?

    Having a Cell modem card in one of these would be just the nuts and I’ve heard that ASUS was going to offer up such a combo.

    are you getting around this somehow?

  29. Andrew R says:

    this is cool, could you theoreticlally wire in any USB device you wanted as long as it would fit? i am going to be buying an Eee pretty soon and i plan to put windows on it, but when i do i need to put the paging file somewhere besides the flash HD, if i could strip down a high speed USB flash drive and put it in there like that it could use it for the paging file, or maybe as extra memory. either way it would be sweet did anybody find out if it affects the external USB ports? great article thanks!

  49. tnkgrl, this is a very nice presentation of bluetooth tech.

    To answer some questions about the mods….

    I have a 4g EEE PC with full Linux and have so far added:
    1. three internal USB
    2. Bluetooth USB (your post helped :D)
    3. Garmin GPS navigator (fits nicely in the screen)
    4. internal SD HC card (12 Gb)
    5. digital thermometer (to measure how hot the EEE runs)
    6. internal FM transmitter (also fits in screen case)
    7. AND a dial-up modem (because my parents haven’t yet gotten high speed…)

    So, no worries abut space then right?

  50. usb says:

    Nice how to! Thanks a lot!

  51. Toothpick Bandit says:

    Tnkgrl, I thought I’d stop by and say thanks for the info. Following your pictures I was able to install my D-link Bluetooth module yesterday. I choose to mount it in the screen bezel; I figured there would be less shielding there to get in the way. The hardest part of the mod was getting the windows drivers working properly but it’s all sorted now.

    Thanks again

  56. Peter Nowak says:

    Hey tnkgrl, (hope you read this, or perhaps someone else can help?)

    I while ago (about 3 yers, sight how time flies) you did a similar mod to a Averatec 1050 when you installed a Bluetooth USB module onto the “3’d” onboard USB port. I picked up on that and did the same mod on my 1050 and it worked great, THANKS FOR THE INFO!!!

    I’m just wondering, if you perhaps still have the info on how to do it available and more specifically, where that 2’nd USB dataline goes, let me explain:

    If you remember, the +5V and 0V and one of the datalines were on the top side of the mainboard, the second dataline was on the underside of the mainboard, under the HD, it was actually a “test point” on the board that you showed to solder to. If I’m not mistaking you even mentioned that you couldn’t find a point for the second dataline on the top side of the mainboard. Anyway, this “testpoint” on the underside of my mainboard has fallen off and as the board is multilayer which meansthat I can’t find that point to the second dataline and I’m just wondering if you happen to know another point that I could find that second dataline to solder to?

    Any help would REALLY be appreciated

    BTW The Averatec forums are down and have been so for a while now, hence I can’t find your pics and comments any more.

    Thanks in advance!


  57. tnkgrl says:

    @Peter Hmmm… I you read this post again carefully you will notice that I linked to the AV1050 mod!

  58. Peter Nowak says:

    Ah yes, there it is, can’t beleive I missed it… Thanks!

    I don’t suppose you remember or perhaps can still check if there is another “test point” for the “USB Data 2” ? (The one underneath the HD)

    As mentioned, that particular testpoint, has been working for 3 year now on my AV1050 but has now fallen off (no doubt due to my bad soldering) and it’s the actual “metal solder point” that has fallen off together with the wire, so I need to find another place to solder a wire onto the “USB Data 2”

    The other 3 connection points (USB Data 1 and 5V and 0V) are just fine…

    Thanks again for the quick reply, this really was a fantastic mod!

  59. tnkgrl says:

    @Peter, I see :/ I’m afraid there’s not much you can do. You can try to follow the trace the test pad was attached to in the hopes of finding another test pad or a component to solder to, or (this is what I’d do) scrape the varnish off the trace and solder directly to it.(this is very delicate work, though).

  60. Peter Nowak says:

    Thanks again tnkgrl! After I read your article again (and refreshed my memory) the “scraping the varnish off” the trace seems like the best suggestion, so I guess I should be looking for the 3 pair of traces (near pin A20) identify the pair that is “USB3” and then scrape off the varnish of “DATA USB2” right? I haven’t had a close look at my mainboard yet, but looking at your pictures, are there really 3 pairs of traces, they look more like 3 single traces to me… Or are they so microscopical that there really are 6 traces all together but on the picture it just looks like 3?

    Thanks again! This really does help, at least there is still hope :)

  61. Peter Nowak says:

    Hi again tnkgrl,
    just wanted to say thanks (yet again) just as you suggested, I scraped the varnish of the trace for “USB DATA2” and connected to that trace. It was the very top trace that was the “USB DATA2” I found the right one and it’s all working again.

    Garmin’s nüvi 265WT improves upon its 200-series predecessors by adding free real-time traffic updates from Navteq (for the life of the device) as well as Bluetooth connectivity to your cell phone. Other significant improvements in the 2×5 series include a predictive technology that provides faster satellite lock, a redesigned screen with more information, terrain maps, and an exciting new photo navigation feature. The 265WT provides complete maps for North America and the handy Text-to-Speech feature, so you get turn-by-turn spoken directions with the real names of streets (e.g. “turn left in 50 feet at Nebraska Way”, rather than merely “turn left in 50 feet”).

    Great internal USB bluetooth mods!
    Just figuring out how to add BT to a Sony Vaio X505…
    BTW: all USB BT dongles I’ve tried so far get quite warm = they use a lot of current even when not in use. If mounted internally, there is no way to switch it off (except adding a switch to 5V). I guess most heat comes from linear voltage converter – BT & USB chips surely work on 3.3 or 2.8V, not 5V. Have you tried to connect a BT module to a voltage lower than 5V inside a computer? USB should still work fine, since it uses LVDS signalling.

  78. Frankie says:

    Tnkgrl, (that’s one of my most favoritest movies, btw)
    I think you mentioned the wireless is had via a mini-pci-e wireless card, if that is correct and i didn’t misread, could one replace that pci-e card, with a wireless+bluetooth mini pci-e card and achieve functionality? Of course, that’s not as fun, and a bit more expensive, but
    that’d be sweet and I wouldn’t have to risk shorting a circuit – I can solder, but I have the distinct peculariarity of having very steady hands – until I try to hold them steady. I can’t seem to solder anything without leaving atleast a 22mm glob of solder in my wake!
