I am very interseted in this project, but I have been unable to download or even get to their website www.bitscope.com because I am currently living in China. Does anyone have a copy of all the details, schematics and PCB to build this project. Scopes even PC scopes I feel still cost to much, this looks like a great project and something that would be very handy for guys like me. I HAVE A DREAM, THAT DREAM IS ONE DAY THE SMOKE WILL NOT COME OUT OF THE LITTLE BLACK THINGS WITH LEGS, I am sure a scope would help a lot, until then all I can do is say to my little legged friends, that smoking is bad for your health

I think I can also confirm that in the manufacturing process of IC's they use smoke, not silicon, this must be a fact, beacuse every device I have has smoke come out, but I have never seen silicon come out.

 

I took a look, but what you're asking for is:

1) A LOT of work!! Many, many pages to copy and post.
2) There are schematics, but no artwork for the boards.
3) Even if the board artwork WERE available, it would do no good, as many chips are discontinued and no longer available.
4) The boards were multilayer; would be difficult for a novice to work with.
5) Their latest products use modern SMT/SMD devices; these wouldn't work with the older designs.
6) In order to even get something working satisfactorily, it would take a considerable amount of research and re-engineering up front.

Yes, it is a pretty nice piece of hardware for what it is. But even the least expensive new BitScope module is $395 US - they have discontinued the kits, as most people would have a hard time with SMT.

Here is a much faster and VERY much less expensive solution for you. Build this buffer hardware for XOScope:
http://xoscope.sourceforge.net/hardware/hardware.html

It is VERY simple, and only requires one IC; a TL082, along with a few other components. Artwork, assembly instructions and photos are all there. If you can't get a TL082, you could use another wide-bandwidth JFET input dual op-amp, or a pair of single JFET op-amps.

For the software, you can download WinScope from this page:
http://www.mitedu.freeserve.co.uk/Downloads/download.htm

It has been released as Freeware.

Granted, this Oscope will be limited to low frequencies; around 20 KHz and only two channels - but you will be up and running with it at minimal effort and expense in very little time.

 

I don't mind if the Bitscope is SMD and no PCB. This is the great thing about China, I can pay a student to build a multilayer PCB, and get a local company to build it next to nothing. Close to my house is like two 4 story buildings, with hundreds of cube type mini retail shopes, everyone of them an agent for some electronics company, e.g. I am not sure if this is cheap but I can get a 16F84A for about .70US cents. There are so many part items, even old stuff, and its always easy to find a replacement for a discontinued part. Things are really cheap over here. But test equiptment, like good scopes are not. Also, I need more than one channel though this scope looks like a good idea for single channel. I can more than likely find those discontinued parts, or at least find replacements.

 

Take another look at that xoscope adapter - it's two channel; he only drew one channel in the schematic since both sides are identical.

Winscope is free. It IS two-channel capable, if you have a stereo sound card. Below the menu bar, the leftmost button starts the trace. the 4th button turns on dual trace.

It's author released a subsequent version, Zyscope, that has more capabilities, but it's not free.

There you have it, a practically free 20 KHz Oscope you can build or have built in a few hours if you take your time.
