Ah theNOP
Your last sentence is probably the best reason that stprue should not spend over 500 on a scope that is like mine.

its depend on the use you are going to do with it.
having only 256 voltage steps to display the peeks is not that bad.

the sampling rate is more important, the higher the better.
if you are not looking for possible distortions in a signal, or looking at modulated complex signals, a digital scope is a pretty good tool
the problem with them is that the distortions are likely to occure faster then the sampling rate.

Me too.

That cartoon was a delight.

(Sometimes I can eat at my kitchen table and sometimes I cannot.)
I put the fluoro tube jt into a woven basket looking like bread, but not as tasty, the tube rests on the top edge so I can move the thing around and maybe eat at the table.

I had dinner with some friends tonight and took it with me since it is so portable. Ha. The house lights even went out for 30 seconds! That was pretty funny.
I still have 1 1/2 hours left for tonight's test with the caps in the way I originally intended.

Ya-Know, 5 1/4 hours is the full evening, Even in winter when the lights are on starting at 4:30, this light would last til 9:45 if I put it on at dusk in december. (Northern Hemisphere, of course.)

Hey Jim, You could test this out now, where's your 5 hour fluoro tube?

Mine has a sampling rate of 10MHz and 2MHz analogue bandwidth.
Good thing too, I sometimes get frequencies that push the analogue limits. I only cannot share the results, but I am willing to have that limitation. sorry.

@ The Gadget
Thanks for the kind remarks    fancy my cartoon being made into a screen saver whacko.

Same here guys . I'm a pack rat and hate to throw stuff away and when i finally do i miss it and either go buy it again or dig in my local Treasure Dumpster and pile it in a a tine 10 x 12 so called "room" being sure to leave a one to two foot path . I am not ashamed anymore !
@Jim . I loved the cartoon and am using it as a desktop background.Cant wait for a final  picture . make sure you put bill and jenna in there ;)that will be a prize.

"A"  Al, Take another look at the picture, Left side window is the pirate, Right window peeking in is the IST, TheNOP is the teach.

Now it gets cryptic, who has the BLUE tori? who has the BIG "O" he he it is LJ. who has the Bedini? hmmmm,(several), who is working on the MOT? Gary.
Gadget, you R on the roof, remember the big round LED light fitting, and I included some wares you sell in your shop. 

Someone has had trouble with a breadboard, its in the rubbish bin.
I make cleavor cartoons lol.

Now, who runs a school for Joul Thiefs? the mystery deepens, an I'm not telling, mums the word. 

Now, is wally there?

Carnt find it, musta left it in the bread thingie,    seriously though, I have lit a fluro tube with my Hazens1 JT, made it gloooo, but I don't hold the record for 5 hours, the battery is on charge right now, so I will hang a fluro on it tomorrow sometime.

@ALL
OOhhhhh I just had my buttons pressed, I an thousands of Australians are being picked on, their pullin our chains hard this time, talk about squeezin/wringing the last ounce of blood outa us.

Just heard on the tellie news here, all airconditioners except the most efficient types are to be banned,       they must have 5 stars. From September next year it comes into force. we are not alowed to even turn ours on, whackos, the dumps are gonna be full with all these old aircond fulla old freon gas. ohhhhhh.

GRRRRR, so how does the Invalid Pensioner afford to replace theirs? (I got 3 of em and 1 on the front verrandah just sitting there) no one is alowed to turn them on, even if they have one.

(I bet Hans VL will have something to say about this)

STUPID GOVERNMENT hogwash.

Thats it, I'm all fired up now, I'm going to make a GIANT BEDINI to power my ineficient airconditioner, and my inefficient washingmachine, and my inefficient Lightning, my power hungry vaccuum cleaner, my power hogging hotwater system, and make enough power to charge the car, and cut the grass in summer time.

Sorry everyone, if I seem a little upset, seems all gov people in AUSTRALIA  have been born with half a brain,      and about as useful as tits on a bull,      and have a loose screw in the top paddock.
Talk about drawing the short straw, fair suck of the sav,

awww time to do serious www search on J B motor, and buy a heep of the most powerful magnets I can find.

I'm GONNA stick my thumb to my nose and wriggle my fingers, an stick my toungue out and blow a rasburry at stupid officialdom,    
Good official officialdom need not feel offended (there a dying  ;)breed).

hooroo all
