Android oscilloscope

Here’s a 2-channel Oscilloscope for your Android phone. It uses a base module driven by a dsPIC for signal processing. From there, an LMX9838 Bluetooth module broadcasts the data to the phone so that the waveform can be displayed. [Yus] ported some Python code he had been using over to a set of Java and XML files in order to get it working on Android. This was actually the first time he worked with the SDK… we’d say he’s a quick learner. See it in action after the break.

[Thanks Gabriel]

    That is a cool hack. Remote O-Scope is sometimes useful and not having to carry your DSO Nano around is a nice plus.

  2. Terry says:

    Any possibility of seeing the same (or similar) app available for jailbroken iphones?

  3. Samuel says:

    Face it: iPhone is a weak device. It will always be like that.

    @Terry
    i don’t think so. hackers generally like open platforms for hacking.

  5. dext3r says:

    lol “open platforms for hacking”

    i’d say hackers are generally up for any challenge, regardless of how “open” the platform is.

    Any chance of getting this on Windows 7 mobile??????

    Ok ok ok , I’m Just kidding!!!(I’ll stick to dead baby jokes)

    Yes, I vomited a little when I said that…. Although if you did port this it would double the number of useful windows 7 mobile apps.

  7. Mio says:

    Whoa.

    Was this built on a dev board? Is there a schematic? I want one. The bluetooth module he used is a leadless part, sadly.

  8. vonskippy says:

    Nice that instead of putting any type of useful voice over, he overlays his information video with some craptastic music.

    Hopefully I didn’t miss the naked pole grinding girls – I stopped watching 15 seconds in.

  9. cpmike says:

    I REALLY wish he included a schematic, because that is awesome.

  10. Wade says:

    Nice. I’d buy one in a heartbeat – talk about voltage isolation! Could have used something like this back when I was troubleshooting hybrid locomotives – trying to debug 350V DC circuits on a moving train is tricky. Would be especially useful when you don’t want to be standing right next to the circuit under test.

  11. fluidic says:

    An oscilloscope, right.

    So why’s the one on my bench so big and heavy? Maybe it’s full of rocks?

  12. rallen71366 says:

    Probably for the same reason mine is: IT’S OLD. The only thing better than this would be if they made a spectrum analyzer module (with tracking gen, of course) that would go up to 8GHz. I would have to sell one of the kids to have it though. :( The holidays just wouldn’t be the same.

  13. MS3FGX says:

    Hm, I wouldn’t mind one of those myself.

  14. Berserk87 says:

    I wish this was commercially available.
    and around $30.

  15. sonicj says:

    @spork i don’t think anything here was hacked. more like developed.

    @Mio any SPP bluetooth adapter module should work. bluesmurf, roving networks, etc.

  16. Addidis says:

    This is awesome. Ive been thinking of making a scope with pic32. This will probably be quite useful when i do.

  17. Terry says:

    I mentioned the iphone because it could be a dual iphone/ipad app which would be pretty cool.

  18. Erik J says:

    @fluidic

    You need somewhere to put all those premium nobs and buttons. :-) And I’m guessing your O-scope will still work in 10 years, this probably won’t.

    Oh man I HAD to go for the Omnia 2 because it’s WinMo’s last gasp, right?
    Gotta get in some WinMo fun while I still can right?
    WRONG
    Modern hardware combined with old OS and all the devs have jumped ship for either IOS, Android or WinPho7.

    Ouch…

    However, this is really really cool for the folks who can make use of it.
    Nice work!!!

  21. Doug says:

    while its very useful and an extremely well thought out and executed hack, does it only sample at 4ksps? and only -8 to 8 volts?

  22. lnm says:

    The schematic has been added to the author’s post.

    LOL song (Giyang). I would definitely buy something like this.

  25. oldschooler says:

    Pretty cool hack! This wouuld give a use to your phone even after it’s outdated or you’ve upgraded (’till you hack the new phone’s OS of course)

  26. elvynopolous says:

    Hah, eat this fanboi haters, iPad oscilloscope:

  27. Jeff Wilson says:

    Go to BackyardBrains.com/ios for a scope app that works with the iphone or ipad.

  28. Richard says:

    We’ve just brought this out for Android which does oscilloscope mode, as well as SPI, I2C, RS232, RS485, CAN, 8-bit data (in/out) and analogue signal generator…
