  90% of the cards I swipe come up with "No match in Database" so does anybody know where I can get more databases for stripe snoop? or am I doing something wrong alltogether? So far I've never gotten a name and that 10% that does come up is "Possibly a Visa Credit Card" with not much info.

• Magstripe Reader
  You must be logged in to reply.
  
  
  I've came across Volume 01 in my local library. Trying to get this Magstripe reader working (a very cool project!). I am confused about the wiring on the DB-15 F connector for the parallel port adapter. What is the purpose of the connection of pin 10 of this connector and pin 3 of the 74541 octal buffer which has no corresponding connection with the magstripe reader or the parallel port (ref schematic p115 and Omron V3A-4 connections to DB15-F connector p112).
  
  Looking forward to your response.
  
  DB

  DB-15 F pin 10 connects to pin 3 on the
  octal buffer, but on the connector
  DB-15 to the Omron card reader there is
  no connection to pin 10. Is this pin
  suppose to be floating?

• B.G. Micro related...
  You must be logged in to reply.
  
  
  I bought the Magtek from B.G.Micro.
  
  Can anyone help me with the wireout on it? From another post I see that
  Red -> Vcc
  Black -> GRD
  Blue -> DATA
  Green -> CLOCK
  
  However this is not coresponding to the information in issue one. What is Vcc?
  There is also a 5th wire coming out of the reader, I believe it is brown.
  Could anyone give me the exact wiring for this relating to the pins on the DB-15 or the cat 5 wiring?
  I am a little slow, lol.
  Any help would be appreciated.

  Well, you could always hook it up to a laptop...
  
  If you haven't got one handy, you may want to consider the Basic Stamp, or another microcontroller. A Basic Stamp II, programming software, manual, and some assorted parts are available as a package deal at most RadioShacks for $79.

  That Basic Stamp II kit at RadioShack does not include an actuall Basic Stamp in it, it has a board in it that has the Basic Stamp integrated called the "Homework Board". It's a lousy waste of $79 because after you get done doing all the (lame) projects that come with it you are stuck with a board that is:
  (a) not good for programming an actual basic stamp
  (b) not good for anything else

• Parallel port adapter with hex buffer
  You must be logged in to reply.
  
  
  The store I went to did not have any octal buffers (74541) so I went with the hex buffer (74367) instead. I have wired it up as follows:
  
  pin 1 = GND
  
  pin 2 = DB15 pin 14
  
  pin 3 = DB25 pin 11
  
  pin 4 = DB15 pin 10
  
  pin 5 = DB25 pin 10
  
  pin 6 = DB15 pin 7
  
  pin 7 = DB25 pin 12
  
  pin 8 = GND
  
  pin 9 = DB15 pin 2
  
  pin 10 = DB25 pin 13
  
  pins 11-14 are unused
  
  pin 15 = GND
  
  pin 16 = +5V
  
  
  
  The card reader works when plugged into the game port, but when I use the parallel port adapter, stripe snoop does not detect anything. Did I wire the buffer correctly? Is there anything I need to configure in the stripe snoop software? Thanks in advance.

• Parallel port adapter with hex buffer
  You must be logged in to reply.
  
  
  I did wire the chip incorrectly. Pins 9 and 10 should be reversed:
  
  pin 9 = DB25 pin 13
  pin 10 = DB15 pin 2
  
  Also I was using an older version of StripeSnoop. Version 1.5 does not have support for the parallel port. Version 1.6-alpha does.

  You must be logged in to reply.
  
  
  Since I don't know for certain what you have, this is a guess. If it bakes your computer, that's your hard luck.
  
  Chances are that if your reader came with a ps/2 connector, it's a "keyboard wedge" reader. That means it emulates a keyboard, so you plug it into a computer in place of the keyboard. When you swipe a card through it, it will "type" the characters into whatever application has focus at the moment. If you open notepad and then swipe the card, the characters will be typed into notepad.

  I'm working on a cheap, DIY writer. The heart of the device is a portable casette recorder modified so that I can drive the magnetic head directly.
  
  The design has a lot of shortcomings, such as the fact that I have to pull the tape out of the casette and tape it to a blank card.
  
  I'll probably be testing it this weekend (11/12-13).

• USB?
  You must be logged in to reply.
  
  
  Is there a way of getting this project to work with USB? I guess the alternative is to simply pay more in the first place to get a USB mag card reader.
  
  A USB driver for it could be an issue though. Perhaps the generic mass storage driver built-in to Mac OS X could be used? I understand the latter would be 'an exercise for the reader', but I'm happy to give it a go.

• Where do you get components?
  You must be logged in to reply.
  
  
  Hey everybody. Firstly, I have to say, "WOW!" Great job with issue 01! Secondly, I'd like to know where people go to get components for their electronic projects. I haven't been doing stuff like this for quite a while (since I was a kid), and I don't know where to get components anymore, other than at a Radio Shack. When I was a kid in the 80's there used to be this electronics store named Manfred's or something like that, in Queens, NYC. You could walk in and say "I need some NPN transistors and an IC with NAND gates" The guy would go into the back and pull out a bunch of packs and ask you what you needed it for and then recommend the right ones. You could get anything there, and they seemed to be always fully stocked. Anyhow, I was actually looking for an SCR today and I went to 3 Radio Shacks, and none had any in stock. I suppose I could mail order one, but it seems silly to pay $5 shipping for a $.69 item.
  
  
  So, I'm curious where all of you go to get parts, especially in the NYC area. I look forward to hearing any comments on this.

  Electronics Express based in NJ has an excellent selection. I've ordered from them numerous times and the people seem very knowledgeable (sic). I'm in Houston, and the most time I've ever waited for a package is 3 days, so I'll bet that NYC would take 1-2 in shipping (or 0 if you stop by)
