I came across a DSO138 DIY Digital Oscilloscope Kit (SMD Soldered Version) on the Internet recently that looked like a fun project for the kids and me to work on together. The price didn’t seem bad at $24 w/free shipping. I ordered the optional clear acrylic case to go with it for another $7.50 more.
Basic specs (from the supplier site):
Maximum real-time sampling rate: 1Msps
Accuracy: 12Bit
Sampling buffer depth: 1024 bytes
Analog bandwidth: 0 – 200KHz
Vertical Sensitivity: 10mV / Div – 5V / Div (1-2-5 progressive manner)
Adjustable vertical displacement, and with instructions
Can freeze at any time waveform display (HOLD function)
Comes with a 1Hz /3.3V square wave test signal source
It came in the mail this weekend. In the box was the case kit, bag of parts, main board, display board, test cable, assembly checklist, and a basic how to use guide:
I plan to post updates on the build experience with photos along the way. Stay tuned!

There is much being said and written these days about the importance of bringing new people, especially young people, into our Hobby. There are many obvious reasons for this. As we all get older or get busy with other aspects of our lives, some will leave the hobby. Also, we have the use of many commercially valuable portions of the RF spectrum and there is always pressure to reallocate bands or segments of bands which are not fully utilized.In my mind, the most important reason to bring new HAMs into our hobby has to do with the energy and new ideas that these folks bring to Amateur Radio. Amateur Radio has always been a learning hobby and new folks help us to keep this important part of what makes our hobby so much fun vibrant.
Anita (AB1QB) and I try to put a lot of time and energy into getting folks started in Amateur Radio and helping them to build their skills and progress. Our Amateur Radio License Classes and the youth outreach work that we’ve been doing are two good examples of this. To make these efforts as successful as they can be, it’s also very important to provide good opportunities for folks who are new to various aspects of Amateur Radio to learn and gain experience. This means becoming an “Elmer” or a HAM Radio mentor to people who are less experienced in some part of the hobby than you are….
