Bitscope stuff

tm_stump
tm_stump 21 days ago

There is some info in here about the Bitscope saga but my BS10 mini won't connect and I'd like to repair the thing.  Is there a schematic available anywhere for the Mini.  I thought I saw schematics on the original Bitscope site and I think I may have downloaded those but apparently my filing system is so secure that I can't find any downloads I may have made.  I may have found the issue but I can't identify the IC I think is causing the problem without a schematic.

Thanks,

Tony

    It may still be obtainable.

    The design is very dated now - possibly not worth a great deal of effort because there are cheap micros that can out-perform it.

    I'm not sure where to post a reply to all but here it is. Thanks for posting all the links and info.  Lot's of good info here and I'll wade through as much as I can to find some answers.  Found some schematics here and from a link that popped up to Silvertone Electronics also in Australia.  They had/have some Bitscope products still on their site and also had a good amount of documentation.  I must have one of the latest versions of the BS10 Mini as none of the pics match the version I have.  As I browse through some of the pics I can see the evolution of the product.  Two pics are attached with three components outlined in the lower left corner of pic #1.  The SOT23-5 component has an A0P or AOP marking and only the A(zero)P shows up in my old SMD Identification catalog as a 'voltage monitor/detection' chip.  This thing is roasting hot over 200 degrees F with an IR cam, plugged in with no activity and no connection.  The two associated resistors are both less that half of the marked values.  I can replace the resistors but I need to positively identify the 5 pin to get a replacement.  I'm not sure how much time I'll spend trying to get the thing to work again, but once I attack the board for component replacement that time might get shortened in a hurry.

    Thanks again.
