The EspoTek Labrador is an open-source board that turns your PC, Raspberry Pi, or Android Smartphone into a full-featured electronics lab bench, complete with oscilloscope, signal generator, and more.
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. It features well-written, rich articles as well as video content that explains everything more clearly than I ever could!
Binary (executable) versions of the software are available for download for several platforms.
For the documentation, please visit the wiki.
If you're looking to build from source but don't know where to start, Qt Creator is the easiest way to get your toes wet!
https://www.qt.io/download-open-source/
When installing, make sure you tick the box to install Qt 5.15 or later.
Once it's installed, 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, cding to the Desktop_Interface directory, then running:
QT_SELECT=qt5 qmake
make
sudo make install
sudo ldconfig
Then, to launch, just type labrador into the terminal. Additional packages may be required, please see the full build instructions on the wiki.
On macOS, additional steps may be required. See issue #238
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 5.0 or later.
There are community contributed 3D printable cases available at Thingiverse, courtesy of SpaceBex and Bostwickenator:
Dave Messink has designed a case that can be laser cut from 3mm plywood. The binding posts and cables he used are from Amazon.
