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!

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:
