The EspoTek Labrador is an open-source board that converts your PC, Raspberry Pi or Android Smartphone and into a full-featured electronics lab bench, complete with oscilloscope, signal generator and more.
More information available at: http://espotek.com/labrador
This repo hosts all of the software and hardware that makes Labrador possible.
If you're new to Labrador or oscilloscopes in general, I strongly recommend checking out the fantastic tutorial series produced by Lief Koepsel (start from the bottom of the page and work your way up):
https://wellys.com/tags/labrador/
It features well-written, rich articles as well as video content that explains everything more clearly than I ever could!
To download binary (executable) versions of the software, go to:
https://github.com/espotek/labrador/releases
The software is re-built automatically each time I make a change to the source code. I recommend always downloading the latest win32, osx-dmg or linux-appimage version, depending on whether you're on Windows, macOS or Linux. Raspberry Pi downloads are not currently automatically built, but an older version is provided at the link above.

I use Qt Creator to build the software interface.

Open Desktop_Interface/Labrador.pro, then Clean All -> Run qmake -> Build All.
If you're on Linux (including Raspberry Pi), then you can also build the software from source by cloning the repo, cd'ing to the Desktop_Interface directory then running:
qmake
make
sudo make install
Then, to launch, just type labrador into the terminal.
To build the AVR software, I use Atmel Studio 7. Just load up the .atsln and push F7. You can use avr-gcc if you don't want to install a full IDE.
The PCB files can be edited in KiCAD 4.0.
Most of the main bugs from the pre-launch period have now been fixed, including synchronisation issues.
Please open an issue if you're aware of any in particular.
If you want to make any suggestions, or better yet, submit some code, please do so here at GitHub.
Suggestions and feature requests belong on the "Issues" page.
For code submissions, look into Pull Requests.
If you just want to say hello and remind me that people are actually using my product (or if you just don't want to make a GitHub account), please email admin@espotek.com
Thanks to all.
