11:25 Diode across the LED should be the other way round, in reverse parallel.

A U.S.Navy technician in the late 1960's was given the credit for developing this handy device and it was called an octopus because of all the wires hanging off it. Now that I am retired maybe I'll finally build one to play with ?
-
Really useful.....many thanks, Bill.
-
I need one of these haha 😄 I should build one in the next month or so would be handy with my recording equipment repairs
-
Nice donation!
-
Thanks. I've seen people use curve tracers before but didn't realise how they worked. Quite simple but cunning.
-
These are perhaps the best diagnostic tools to see the behavior of the component

In my opinion one of the most useful gadgets. I'm using a Hameg component tester for nearly 25 years to check IGBT's and other power components. It never failed.😁

Gracias amigo

Unless I have completely misunderstood (which is quite possible), in the circuit diagram of the component tester at 10:15 the scope connections X and Y are reversed.

Hello dear colleague. I am Mauro, a technician and curator at the Electronics Museum. Greetings from Brazil for the excellent video and thanks for sharing!

Years ago I built a curve tracer out of Popular Electronics Magazine. My brother broke into my storage and sold off all of my Lab equipment years ago. I'm just starting to build up my Electronics Laboratory Bench All over again. Replacing everything makes me less angry. I will make another curve tracer. Everythings replaceable.

I made one of these back in 1985 with a 12.6 v ac Transformer. You can also change your H and V controls on your scope as well to view the complete waveform if it falls outside the screen. I would be curious of the 3 ac output voltages from the kit.

Hii This tester is very simple. You just need to make two-lead sine wave generators. x.y -0-180 degree phase angle inverse sine. Drive with popular ic8038 and even better ad9833 generator .or simple oscillator .transformer or transformerless .opamp. voltage is adjustable from 5v ac to 24v and frequency from 50hz to 1000hz. current should not exceed 1ma to 5mA. it is enough to know the logic of a resistor and a coil.

Excellent video. I face problem when using Tunnel Diode. Can you please suggest how to deal with Tunnel diode?

Thanks, Bill. Excellent as always. Could you build one of these using a signal generator?

Не хватает характеристик катушки индуктивности и куда массу цеплять у щупа. Почему не указали ?
