LCS-1M - A Low-Cost Hobby Oscilloscope
Building or buying and then using your oscilloscope is one thing. At least as much fun - if not more! - is
understanding how it works.
Click on the buttons on the left to read up on the details:
- The overview page gives a short introduction into to overall design. That should help getting the big
- The next pages each explain one page of the circuit schematic - what the circuit does, some
considerations that went into the design (why us the circuit built the way it is), etc.
- The firmware page gives a high-level overview of the firmware that gets burned into the
microcontroller. This is the program (written in a version of BASIC) that controls the oscilloscope
hardware and communicates with the PC.
- The PC Software pages gives an overview over the scope program that runs on the PC, including
some screenshots. For more details please go to the "Use It" section (via the menu bar on the top
of the page).
- The Pictures pages contains several photographs of the scope - including the breadboard version I
used to develop and debug the circuit.
- Finally, on the Download page you can get all the design files (circuit schematic and printed
circuit board layout, bill of material, firmware, PC software, and the programming software.
