Oscilloscope projects

[Ian Gowen]

I just got a used oscilloscope for $30 at a garage sale last
saturday and have been having fun playing around with it.
Now, I was wondering anyone knows about a site where I can
find oscilloscope projects, fun stuff to do, etc.

Thanks in advance

Ian

Hiya!

You could try playijng Star Wars on it?

There are a large number of books available on how
oscilloscopes work, and how to use them.

Check your local library, or used book store. You might
also find some books for sale on EBay.

See if it has Z input for intensity modulation and than figure how to hook
it up to a TV set to display a picture on the scope crt.

Does anyone have any idea how to do this? Some say you need special
equipment, some say you don't. Is it possible to make it work with
just a scope?

Like, why reinvent the wheel? DOH. A nice new TV is only $149 at Wal-mart.

Why not go the other way? Build an interface to turn a TV into an
oscilloscope.

Because the Y will not be fast enough for any useful purpose, and the X
timebase will be linked to the HT.

Would be a PIA, but if someone could do it, and make an XY monitor with
a fast Y deflection, then PLEASE share, as that would be Very useful.

I used to take two time bases and put them in a Tek 7000 series scope. One
time base in the vertical compartment set to sweep at 60 hz (set time base
at 5ms/ div (maybe 10ms) and use the variable to fine tune.) the other time
base in the horizontal compartment (set to 10us/div, use the variable to
fine tune). Connect the video signal to the Z axis on the rear of the
scope, feed the same signal to both time bases external trigger inputs.
Trigger both time bases, set the time bases to the correct speed with
time/div and the variable controls. You will be able to see the video on
the scope, adjust intensity for best picture. It was weird watching things
on the green phosphor and then put the blue crt filter on !!! Stretching the
picture with the time base variables was cool too. Not a good picture but it
works and fun to play with. Take Care

First, I already have a TV. Second, I only paid $30 for the scope. Third,
you obviously don't have the true spirit of geekdom. Otherwise you'd look
at a tv image displayed on an oscilloscope and say "cooooooool"

I like doing "stupid stuff" for fun. <g>

Like, why re-invent the wheel? DOH. A nice, used oscilloscope can be had for
$50 on eBay.

I didn't say anythiong about changing the TV's timebase to that of the
signal. I had thought that what the TV would be used for is exactly the
same as a 'scope in a PC: the TV CRT or the PC's monitor are just used
for displaying, all else is done in the 'box' including capturing the
signal and making it ready for display. The TV, in other words, would
have the normal raster and sweep speed as it does when used as a TV.

Would be a PIA, but if someone could do it, and make an XY monitor
with
a fast Y deflection, then PLEASE share, as that would be Very useful.

PITA? Why? I don't see it as being quite as bad as using an array of
LEDs for a scope display. :-(

Yeah, that, too. What's a good one to buy? I see some Tek 2235 scopes
going for $100 to $150. How about a HP 1740 series? Please tell us
the lemons, besides the infamous failing chip in the Tek 24xx series.
