Curve tracer , kit info ?

[KD0CAC]

I was on Dave's EEVblog , http://www.eevblog.com/forum/beginne...?topicseen#new
And saw this tester , and have been looking for a kit , there seemed to have been some yrs ago , but not much now .

Depending on what you want, they are very easy to build (the one in the blog is no longer available).

A search for "curve tracer" will give you plenty of things to look at.

This is as simple as they get http://www.interalia.plus.com/q_tech3.htm

If You want a real Curve Tracer this one looks good, and connects to a computer via USB.

I think I would go for the built and tested PCB, unless you can do SMD soldering. (Not bad for $82.50)


If you have a scope and only need a Junction tester they are very simple as mentioned in the post above.

I found that site , but what your referring to is just the controller board , populated but not programed .
I do SMD work and would be interested in a kit .
I have a new digital scope , and keeping an eye out for a analog .
Leaning towards this one but they are out of stock , so more time for gathering info , http://www.actracer.com/
Thanks

That one looks good for checking junctions, capacitors and inductors.

A real Curve tracer will have 3 input connections and show the Characteristic Curve of 3 pin devices.

Let me know if you want to build one from scratch, I can send a diagram/article I published LONG ago on a tracer.

I would like to see that Tom.

I built a few back in the day from some article maybe that was your design.

I still have one, and if I remember it just has a transformer and a few resistors.

I had a real good curve tracer at work and it was good for Matching Transistor Pairs.

Tom , I would defiantly be interested .
I like to make build stuff , repair stuff and my tool-jones is getting new life with the new subject , electronics .
Coming from all aspects of construction , injured out in mid 80s ,
Then auto repair , lots of diagnostics , emissions and computer , but $60,000 in tools stolen about 15 yrs ago .
Now with ham radio , adding more electronic learning , good timing now that the body is getting too old to do heavy work of the 1st two .

John,

You just need to Shift Gears on occasion. You never really get to old.

Building is what Amateur Radio was all about in the good old days. Nice to know others want to Build today.

If you build one from scratch, I am sure Tom's Design is as good as any.

Enjoy Building your project, and new scope.
