The Crystal a-Maze

A Beginner's Project With Possibilities

There's an amazingly cheap project available from multiple Chinese sellers that offers a good starting point for someone who has never built an electronics gismo before.  It's a tester that's good for go/nogo and frequency identification of crystals up to around 50Mh/z.  In theory it should check ceramic resonators and filters too, and maybe it has other uses, like a frequency meter or maybe - with a lille insight - can be used to indirectly measure inductance and capacitance.

I bought mine here for only £2.11 (British Pounds) and that included the shipping from China!  They vendor wants a massive £0.25 shipping now though! I've been looking at the little bag of parts for a couple of weeks now, so it's time to get the soldering iron out...
