Inexpensive DIY Digital Oscilloscope Kit

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
  • Input impedance: 1MΩ
  • Maximum input voltage: 50Vpp (1: 1 probe), 400Vpp (10: 1 probe)
  • Coupling modes: DC / AC / GND
  • The horizontal time base range: 10μs / Div – 50s / Div (1-2-5 progressive manner)
  • With automatic, regular and one-shot mode, easy to capture the moment waveform
  • Available rising or falling-edge trigger
  • Adjustable trigger level position, and with instructions
  • Observable previous trigger waveform (negative delay)
  • 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:

Tech Night – 40m QRP CW Pixie Kit

Abby at Tech Night - Building her Pixie KitConnor (KC1GGX) and myself (Abby-AB1BY) both participated in the club’s November Tech Night. Our mission for the night was to build a 40m QRP CW Pixie Kit. Going in I was nervous – I had never soldered before – and wasn’t sure if I would understand how to put it together. Connor had done some soldering and was feeling more confident.


When we walked into the room Brian (AB1ZO) had all the kits neatly set out for everyone so we could get right to work. We opened the kits and instructions and I was overwhelmed! Thankfully we had some very experienced Elmers to help us out. Bill (K1TWO) and Charlie (AB1ZN) were extremely helpful in improving our soldering techniques and figuring out what went where. At first, I was very slow and asked a lot of questions, but as the night went on I think my technique got better and things went faster.


Connor at Tech Night - Building his Pixie KitWe worked the whole time and were the last two to finish, but when it came time to test our kits out they both worked! I was very proud of myself and learned a lot. Connor also had a great time and wants to do another project with soldering!

We would like to thank Brian and everyone involved for putting this fun tech night together.

Our Club Moving Forward Into 2017

Our club has accomplished a great deal in the last year. We have grown to over 130 members. We have introduced many new people to Amateur Radio, helped them to earn their Licenses and worked with them to get on the air and develop their knowledge and operating skills. We’ve also worked hard to provide opportunities to enjoy and learn about Amateur Radio for members of our club and for the Amateur Radio community which we are a part of.

Much of the credit for our club’s success this past year belongs to you, our members. We very much appreciate all that you have done to contribute to our success and the fun that we have all had as part of what we have done together. Your enthusiasm and support provide great encouragement and inspiration to the many new members who have joined us as well as to all of us who are part of our club’s Leadership Team.

We, as your club’s Executive Committee, have been working on a set of goals and plans to continue on this path during 2017 – to provide even better opportunities for our members to learn more about and to enjoy Amateur Radio, to continue to encourage people to join the Amateur Radio Service, and to provide opportunities for STEM learning for young people.

Our goals and focus for 2017 centers around continued success in and focus on the following areas to benefit both our members and our community as a whole:

To do these things and to be successful as a growing club, we are also pursuing status as a 501(c)(3) non-profit. This will enable our club to more effectively secure support from other groups to further our work towards these goals.

Each of us has taken ownership for creating a focus on meeting different aspects of our goals for this year. We are planning to share more about our plans for 2017 at our February Club Meeting.

We are asking that each of you, as members, to consider how you can get the most from all of these and the other opportunities that our club provides. We are working hard to try to create something for everyone that can provide enjoyable opportunities to have fun, to contribute, and to expand the value that we all create and derive by being part of the Amateur Radio Service. We are also asking each of you, our members, to consider helping us with these initiatives in 2017.

Amateur Radio at MakeIt Labs

On Saturday, January 28th the Nashua Area Radio Club (Nashua ARC) will be hosting a special event for Interested kids, parents, and friends in the community about the joy of amateur radio at MakeIt Labs in Nashua from 9:00 am – 3:00 pm. You may drop in at any time and stay as long as you like to participate! Among our activities, you can:

Get-On-The-Air Station (GOTA)

Ham Radio GOTA StationThis is amateur radio at its best and what it’s known for! We invite you to get on the air and make a contact (we call them QSO’s — pronounced: cue-so) somewhere in the world! You might be able to make a new friend in Germany or even Japan! Making contacts sits at the heart of amateur radio and is an activity that brings people together. So don’t be shy, step up, and hit the push-to-talk button!

Satellite Station Display

AMSAT LogoThe Radio Amateur Satellite Corporation (AMSAT) began in 1969 to foster amateur radio participation in space research and communication. Currently, AMSAT groups help advance the state of the art in space science, space education, and space technology. Come learn about what components go into constructing a station capable of contacting a satellite and what antennas, and smart phone apps, operators use to keep a pulse on the satellite location.

Digital Amateur Television (DATV)

DATV Transceiver RackNot only are amateur radio operators granted privileges to transmit speech, but we also can send fast-scan data such as TV signals! Many operators have experimented with how to homebrew their own fast-scan TV stations, and our club president Fred (AB1OC) and our member Skip (K1NKR) have chosen to use construct a station which uses a Raspberry Pi (RPi) with an Arduino shield to sit at the heart of the transceiver. The RPi is the brains of the TV which runs Linux and among other things is responsible for sequencing, transmit/receive control, automatic VSWR monitoring, and a touch-screen controlling interface to configure and operate the system. Learn about what it takes to build and operate one of these stations. We may even be able to make a contact!

Kit Building with Nashua ARC

Oscilloscope KitThe Nashua ARC holds kit-building nights were both inexperienced and experienced members homebrew in a relaxed, learning environment. In the past, we have built Pixie QRP (low-wattage) kits transmitting Morse Code on the 40m amateur band. But, on February 18 from 1 – 5 pm, First Church in Nashua, Nauss Hall, we will build the digital oscilloscope kit DSO138 (shown to left). This kit comes with a clear acrylic case to protect it, build instructions, and among its specs has a 1 Msps sampling rate, 12-bit accuracy, 200 kHz bandwidth (good for audio signals), capable of freezing the waveform display, and comes with a 1Hz / 3.3V test source. We invite you to join us and will bring some kits with us. More info can be found on our website at https://www.n1fd.org/2016/03/27/inexpensive-diy-digital-oscilloscope-kit/.

We hope you will join us for our event! Please bring friends, family, but most importantly we want you to have fun and enjoy this hobby with us!!
