A look at a Crystal Oscillator Frequency Counter Tester

1A few weeks ago, I had a few crystal oscillators that weren’t working properly so I bought this crystal oscillator tester kit from eBay. It was sort of an impulse buy because I can test oscillators in a test circuit so I didn’t really need this. It’s been a while since I’ve purchased a kit like this so I was excited anyway. The last time I put together a circuit board kit like this was back in my first semester of college!

You can pick up your own here. (Just search the name of it on your country’s eBay if you’re not in Canada.)2The parts were packaged well. Not a single bent component lead.3I admire every circuit board I come across more these days with my work that I do on my own circuit boards. One thing I enjoyed about this board were the wide diameter pads which made it really easy to solder. The board is nice and thick (thicker than 1.6mm I think), and it measures in at 8 x 5.4cm.4After putting this together, it makes me want to start making boards larger than what I’ve been doing so far, which has been bounded by 5x5cm because it’s cheaper to get made than anything bigger. I put in a 9v battery clip instead of the included barrel jack because I never use those.

5Like I said, the soldering was enjoyable because of the size of the pads. I always try to make the pads on my boards as large as possible but it’s usually too tight for space or I’m scared it’s going to come out wrong…
6It works! I tested it with a few good 16MHz oscillators and it’s pretty close, either on the dot or 15.999 as in the image. I also tested that broken oscillator and it jumps around to weird frequencies from 0 to 16MHz.

I hope you enjoyed the look at this kit!
