Labrador: Easy-to-Use, Open-Source, All-in-One USB Oscilloscope, Signal Generator, Power Supply, Logic Analyzer, Multimeter for Windows, Mac, Linux, Android, Raspberry Pi

I've had it for 2 hours and it's already been put to work. Very much a "plug-and-play" device as well. While it doesn't quite have the feature set or resolution of a $400 PicoScope, it comes amazingly close for an order of magnitude less money. The 2 oscilloscope inputs and separate signal generator outputs, plus the ability to generate a custom output waveform really put it over the top for me. Already ordered a few BNC connectors and a small project box so I can take this with me whenever I travel for work... seems like we always need a 'scope when there isn't one around. It's going to be very helpful for troubleshooting assorted instrumentation.The software is also very straightforward to setup and use once you get the hang of the shortcuts. Overall great little product.

The Labrador is really cleverly engineered. I love being able to analyze waveform outputs of circuits I’m tinkering with. As a hobbyist, I wasn’t prepared to invest many hundreds of dollars (or more) in a scope. But, utilizing an existing computer for processing and display, and mass producing the chip brings the price here to $30, which is amazing. It certainly meets all my needs as a casual user. I put the chip in a simple plastic box, and connected leads for 2 scope inputs, 1 waveform generator, plus a common ground, plus the USB (which communicates with the computer and also provides power). I had a slight hangup, which turned out to be a bad micro usb cable. Some do power but not data, so watch out for that. A better quick start guide would be appreciated. It’s actually so simple to set up that it can be mildly confusing, which sounds strange, but is true — I wanted to connect more wires, but most of the pins were not needed in a simple application, and power comes over the USB, as mentioned before. Software installation was easy. I would like to see a way to save your settings between sessions in the software. Great job!

The sample rate is slow resulting in waveforms that look like they have a lot of noise. So if you just looking for a signal without concern for noise, this works great. It has a lot of nice features (function generator, on screen measuring, a very weak controllable power supply), a little funky, but do-able.While it is difficult to brick it, in my carelessness, I managed to do so :(

I had hoped that I could use an old Android phone as a display for this unit. The app downloaded just fine, but when I powered the system on, The display stated the labrador wanted to perform calibration, and even after following the screen instructions multiple times, I was never able to successfully get it fully up. There was no real support for how to troubleshoot this issue.. unsure if the board had an issue - no way to debug if I had a firmware, software, or hardware issue. Trying to install on a Win 10 PC did not want to work at all - and discovered that the labrador downloaded the app from the first device, making it captive to only the first device! My advice: be careful what platform you pick.. support for this was thin on the ground (this review submitted > 2 years after purchase and setup occurred).

The smallest O-scope I've ever heard of. Yes, it does other functions as well but to get a nicely featured scope in a size not much bigger than a postage stamp, wow. Plus it is powered only by the micro USB port. I have only just begun using it but so far I am quite impressed with it's performance. I put it in a little 99 cent storage bin and made two holes for the micro USB and BNC connector I added for connection to a O-scope probe.(pictures attached) It has an easily removable lid to change the connections for other functions. So far it appears to be an excellent investment.

This is a pretty awesome tool! It doesn't promise to replace a professional lab, but it is certainly a lot more portable and can basically do most things that most people would need in most situations at a significantly reduced cost. As a computer engineering student, I have personally used the Labrador so I could work on assignments away from campus if need be. It has served me well. I have successfully used it on both Linux and Windows. I haven't gotten the phone app to work, but I think it might just be an issue with the OTG on my phone. There's also 3d printed cases out there that work well to keep it protected. Highly recommended!

This device is absolutely perfect for when you need some basic measurement capabilities. If you want to debug a motor controller, it is perfect.It isn't a great oscilloscope, nor a great signal generator. There is a fair bit of noise, there isn't a front panel. And you supply your own leads. But it *is* a superb tool for what it is and you can't beat the price. I bought two, one for the student I am tutoring, one for me. I love it!

I wasn't really expecting that much for the price, but after using it I am almost floored at how much bang for your buck you get here.I've been using it to measure audio waves from synthesizers and it seems to work quite well for those purposes.It also has a signal generator, power supply, and multimeter-type-thing. I haven't used these tools very much, but when I did use them they seemed to work just fine within their defined limits.Overall I'd say definitely get this if you are a beginner who wants a capable set of lab tools on a budget.The fact that it's open source makes it even better.
