OsciPrime Oscilloscope

★★★★★ Can't beat the price! I'm an iOS developer; I applaud the software developers for releasing this app. It's simple and effective and it breathes new life into old gear. While I'm sure some people would like more complex features & user interface gimmicks, I'm quite happy with the $5 US price and the fact that it runs on old Android hardware. That gets it 5 stars right there. I ran it on my old Samsung Galaxy Tab - I haven't found a worthwhile use for this device since I bought the darn thing, until now. While it would be nice if all the dialogs fit on the screen (there are a LOT of options on some dialogs and it pushes the DONE button off the screen at times), the fact that I can scroll and still access everything keeps it functional. I plan to use this to teach my kids sound theory along with a homemade Arduino sound synthesizer and an Access Virus TI.

★★★★★ A great little tool! I just hooked up a voltage divider like so: Gnd - 2.2KOhm - Mic In - 22KOhm - Test point Works like a charm (you need to use 2.2KOhm to make the phone detect that you are using an external mic). Functionality is basic, but for checking noise on a power rail it's just what the doctor ordered. Well done guys!

★★☆☆☆ Does not work as expected I needed to be able to use the mic jack to do ttl testing. This does not allow for it. Perhaps I misunderstood or read to much into the description. Without the usb adapter it is only good for picking up and plotting audio from the built in mic. PLEASE NOTE: This only tested this products ability to monitor TTL logic signals from a serial interface. No other functional testing was done. From: Andreas Rudolf Aug 6, 2013 Dear Mr Slaughter I am writing to you because of your review for the Android Google Play Store application "OsciPrime Oscilloscope". Not long ago, Google has made it possible for developers to publicly reply to user reviews. However, I would rather not reply to this review publicly. My suggestion is that you remove your comment. You can still keep the rating of course. However, it would be a nice thing to rethink your review. After all, it is technically not possible to measure TTL signals over an audio input line, and this is certainly not our fault, neither have we ever indicated or implied such a functionality. We are sorry if there has been any confusion with the product, the OsciPrime software and hardware are both completely open source and we try to ke
