Found 7th Mar 2014
Here is one for the electronics hacker, a digital oscilloscope at a better price than most from HK on ebay. Best of all in stock for next day delivery and no customs charges.

I appreciate this has a limited audience but hopefully if you like to tinker with electronics like I do then it might help someone.

Fantastic price

If you are ordering 4% Quidco from Rapid.

This is the lower end of bandwidth for 'scopes and is really only useful for audio or slower digital circuits, price seems okay for this.
As a rule of thumb, your scope's bandwidth should be at least five times higher than the fastest digital clock rate in your system under test
If you can use your pc or laptop, then this seems like a good buy for a dabbler looking at audio frquencies, at only £55.99 from Amazon, only slightly lower bandwidth at 20 MHz.

Additionally, the software for the Hantek is open source C++, enabling you to adapt or write your own code if you can.
If you want something faster, there is the 50MHz version at £131

And the 100 MHz one at £164

The Hantek are Chinese made and designed (much cheapness), but the review I read on the 100 MHz one was quite positive:

If your budget can strech a little more, a lot more functionality/performance can be had...

I have one of these and it's a fantastic device for anybody who enjoys playing about with Arduino, Arm Cortex-M or similar devices. It's fast enough for most board level or peripheral interconnects and it's priceless for debugging. The PC based ones are okay but nothing beats having a dedicated device that doesn't glitch or slowdown or have its window covered up. Want to know what pulse with you're *actually* sending? Want to see if your output signals are actually properly square? Don't work it out - measure it.

Fantastic price too.

At first glance, I thought it was a microwave worth 179 pounds! haha!

Heart monitor?
I did a wiki search: en.wikipedia.org/wik…ope
I still have no idea what this is for...
I used to edit a lot of video, is this ANYTHING to do with that? lol :|:|:|

Good value.:)

Can't say that I do. no.

Does it have iPod Dock?

Here is one for the electronics hacker


At 25MHz seriously?

Your having a baaaaath mate!

No. But anyone who does would want to know the width

I too don't really no what on earth i could use it for.. but it still something i want!!

The devices I mentioned, the DSP processing is done within the device. Your laptop or pc is used only for graphic/display abilities. Note the large FPGA Xilinx chip in the image:

As much chance this 'dedicated' 'scope' will glitch...Because all the number crunching is done externally, You could potentially use an old laptop or pc, maybe even a single core pentium would be okay, it's not critical.

And the added advantage is the screen size is as big as your monitor....

You could have done everything you mention with this:

You really need to understand the circuit function first.
For example take a faulty guitar amplifier. Assuming the power supply and speaker is okay..
You could check the output of the guitar pick-up, seeing if their is a signal. If okay, you would check the first stage of the pre-amp, if there is the expected signal output here, you would move up to the next stage. Eventually, you would find no output from one of the stages --- were the fault lies.
Other uses included, digital circuits, checking for clock and expected logic signals. SWMP's although, you shouldn't mess with these. Video circuits etc etc.
It's the Swiss army knife for the electronic engineer. If you have not heard of one before, then you are wasting your money buying one as you won't know how to use it. Buy a multimeter for a few quid.

Cheaper in aldi and it's in farm foods on BOGOF.

They can be used for assessing the age of over-ripened cheese...

Scope .....droool ......want it .....Now!.... droool.... oO

First thing I do when I buy cheese is to plug my scope into it,
