LCS-1M - A Full-Featured, Low-Cost Hobby Oscilloscope

Step 3 Design

Building or buying and then using your oscilloscope is one thing. At least as much fun - if not more! - is understanding how it works. We will have a detailed look at the circuit schematic in the next few pages. If you don't find that interesting, just jump ahead to get a look at how the scope is put together in practice.

The next pages will show the following:

• The overview page gives a short introduction into to overall design. That should help getting the big picture.
• 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.

does any one have a complete parts list for LCS-1M - digital Oscilloscope i just started college for electronic engineering and i am really interested in building this scope to help me with my studies

You can get the parts list (also commonly called "bill of materials" or "BOM") from my scope website, go to Design --> Download:

Good luck with the scope if you decide to build it. I got quite a few emails from people who successfully put it together without any problems so I dare say the design is solid.
