What Can I Do with My Old Scope?

[JBrock]

What are some easy things I can do with my old 20MHz 2-channel CRT scope? I can display a swept triangle wave, but maybe you have better ideas.

I saw a circuit for making an analog clock display, THAT was cool!

Any way to interface it my PC to display cyptic symbols or messages?

Use 60 hz on one axis/input .... put a signal generator on the other....many possible combinations.

You can use it to repair circuits operating below 20 MHz.

Give it to me.

This is pretty cool use for a scope:

SparkFun Electronics - AVR Oscilloscope Clock Kit v3.1

Give it to me.

You dont know this guy. He might be weird. You should give it to me instead.

You could add a simple circuit to use it as a out of it.

Though said 20MHz, it would almost work to 30MHz , but with lesser accuracy perhaps. most Micro-controller circuit analysis and general electronic tracing except VHF /UHF etc., can be done with the same. Old is a psychological term. Until the cathode looses its capacity and the illumination and focusing become problematic, nothing may be called old(aged). Many a time Meg ohm resistors used in scopes give way and if you replace them and few electrolytic caps, the scope returns back to its near original state, I believe.

Thanks everybody for the comments.
Lefty, that Sparkfun kit is what I saw and I really like it. I am putting it on my wish-list!

Carlsbad has my favorite beach, it is by the smoke stack, smooth break low seaweed, no rocks, would you not rather be surfing?
