Tim Bitson Basic Stamp Lightning Activity Monitor..... HELP !!

edited 2002-07-02 01:50 in General Discussion
I have a question about the circuit mentioned above in the subject
line. Tim's project consists of the LSU board and the Stamp Display
board. The schematic for the Stamp display board shows connections
to the 9VDC supply ( the battery) and also connections to +5VDC, but
I can find no reference on Tim's page

(http://homepage.mac.com/tbitson/weather/bslam/index.html)

about where he is getting this voltage. He is using a Basic Stamp 2
carrier board, and as far as I know, this board does NOT contain a
+5VDC source !!


Anyone have any answers?????

Thank you...

    The stamp is outputing the 5 volts. Since you have 9 volts applied to Vin
    Vdd outputs a regulated 5 volts. Watch your current though, the stamp
    regulator is limited.

    jim, i looked at the schematic at that site, and as Ricky said, the stamp
    is outputting the +5V from its voltage regulator. it looks as if this guy
    has been using his setup for a while, and if he posted those schematics im
    sure the stamp can handle it, just make sure you dont short out the +5V
    from the basic stamp or you could blow the regulator, forcing you to solder
    on a new one or buy a new stamp

    Does anyone know exactly how much current the Stamp regulator can handle?

    Paul,

    After doing a LOT of searching, I located this page.

    http://www.acroname.com/robotics/info/examples/srf04-1/srf04-1.html

    It states that the onboard 5V regulator for the BS2 is limited to
    50ma.

    For what it's worth.....
