Oscilloscopes...
I have been after an oscilloscope for many years now, I even signed up on ebay years ago just to bid on one (I lost my original account, as I no longer have the email address I used back then, and cant remember the password!!).
Its taken many years, but I have finally managed to get not one, but THREE scopes. Will probably be forced by my other half to sell one or more on ebay, but hope to keep at least two of them :)
What is a scope? If you know, then you can skip this bit, and move on down to a interesting link further down, which describes a online virtual scope.
Electricity is invisible, so its very hard to see what is going on in a circuit. You cant see the flow of electricity like you can water, all you can do is measure it.
A normal meter can show you the voltage that is present at a certain point, but what if that voltage is rapidly changing? Most meters would just show an average reading.
You need to really SEE what the electricity is doing in order to really understand it, and improve your designing / fixing skills.
The scope allows just that, it draws the waveform of the electricity on screen,
and allows you to view it in a nice friendly manner.
There are many links on google and other search engines which show you more about scopes, but for newbies to electronics, and even people experienced the following link may be of interest.

Its a online scope, just like the real think, you can plug in the test leads, and see the wave form on screen. Even better, you can twiddle around with all the knobs and buttons to see what happens, all totally safe, no fear of electrocution or blowing up a real expensive scope. If you are considering a scope, or need to learn about them, I can recommend a visit to that site. Its based on a real scope, and just shows what you can do with macromedia.
Back to the scopes I purchased on ebay, the first one was an absolute bargain, a advance instruments 0s2000r for the grand sum of 2.25 uk pounds!
The next one is a meguro mo-1253 40mhz scope, both work fine, but I dont have any service or operators manuals for them, so if anyone out there has a copy they could email me I would be over the moon!
Im awaiting arrival of the third, a philips scope, when that arrives I can update this blog, and maybe put some pics of them in.
Managed to pick up some nice leads on ebay cheaply also, cheap even considering I bought them from a USA seller, and Im in the UK. Delivery was very fast too,faster than some UK sellers to other UK sellers!
