    If the QRE1113 has a transistor output, why build the amplifier circuit following the reflectance sensor? Why not just route the output from the QRE1113 straight to the microcontroller (an ATmega in this case, right?) - The transistor should only drop about 0.7V, right? Or am I missing something really basic?

    I know. I hate it when I accidentally your whole window.

  • Product COM-10444 | about 3 years ago

    This IC plus three higher-current external transistors? Just use them as switching amps. Then you have all the current/voltage capacity you want if you design it right.

    Does anyone else recognize those exact same checks and “x’s” in the quiz as the same ones from webassign?

    Whoa there! How can I be so sure that I won’t catch anything from your chips?

    THANK YOU! Far too few people have seen airplane! We’ll be attacking from the south, a flight of four planes, low and fast. We’ll be making our run at dawn. “But when will you return!?” I can’t tell you that. Classified.

    Nate? Didn’t know about the konami code? I mean, come on man. You call yourself a hacker? I mean, I’m 16 and I have cheated on Contra. Step up your game!<br />
    Good work, guys.

  • Product DEV-09734 | about 4 years ago

    The price of this board is ludicrous. 55 dollars? even at BatchPCB’s consumer pricing, thats only about a 15 dollar board (worst case) plus 10 dollars without a volume discount for the micro, then, what, 10 bucks for the rest of the parts? You are making a 40% profit on this board worst case. I’ve never had a problem with SFE (or their pricing, anyone on the sfe staff can see my purchase record) but this seems a little insane.

  • News - Arduino Announces New Pro… | about 4 years ago

    The Uno’s ‘8U2 looks to have the ISP header broken out, just not populated. You could certainly reprogram it, just not with the Arduino IDE (Since it’s the middle man between the Arduino IDE and the ATmega328).

  • News - Arduino Announces New Pro… | about 4 years ago

    I haven’t looked at the schematic yet, but depending on the ‘2650’s breakouts, you can add up to 64KB more SRAM to the thing externally. It has external memory support. Address and Data busses are muxed together on port a, and the high order address byte is on port c. !ALE, !WR, and !RD are available on port g. Give'r a look!

No public wish lists :(
