In Circuit Curve Tracer, Component Tester Parts List:

To expand this post, click the large black title above.

This curve tracer/ signature tracer/ component tester, is very versatile. It's safe to test components right in their circuit board, supplying a maximum of only 1 mA. Great for testing semiconductors, all the way to relays! I'm working on the design (actually right now) I figure I will give everyone a head start, so you can gather the parts for the upcoming video. I re-designed my old tracer to make a really simple circuit, using components we have already experimented with. The signal source for this tracer is... you guessed it, the Wien Bridge Oscillator we built together in the previous video. This is just the first parts list to make the tracer work with your oscilloscope, we will add some really neat features to this as well in the next upcoming video's. (we will build this in sections together, then join them up.) This circuit will lead to a future vacuum tube curve tracer as well!

Here is the parts list, every add-on section will have it's own parts list at the time of the build. This list will make a functioning curve tracer, with the addition of the Wien Bridge Oscillator circuit we just built.

Please note this list may be updated at any time, so keep an eye on this list for "added components."

• 1-     TL072 or 1- TL074
• 3-     220K resistors. 
• 1-     150K resistor.
• 1-     100K VR "can be small" Almost any size will do.
• 2-     22K resistors.
• 1-     7.15K resistor,  This value can be experimented with 7 to 10K
• 2-    100 ohm resistors.

All resistors (fixed) can be 1/4 or 1/2 Watt... What ever you have. I suggest having more resistors than suggested above (their cheap) get at least 10 of each. As in the Wien Bridge build, this circuit will require a +15 and -15 Volt supply.

Well, I'm back to the bench now, Happy 4th to you all! Today is our Canada day (July 1st) Happy 1st to all as well!
