  • Anyone have suggestions about a circuit breaker type addon to replace the 5A fuses? I'd much rather have to push to reset a circuit breaker (even if it costs a bit more) than having to replace fuses over a mis-wired component.

  • For those of you that bought this along with the FTDI Basic Programmer, be advised that per Michelle at SF, the Basic will not reset the chip for programming from the Arduino IDE. This will result in various errors basically indicating that the arduino didn't respond. In order to get the Basic to properly upload the sketches to your Arduino, you will need to jumper DTR to the RESET pin on the Arduino (pin 1) with a .1uf capacitor.

    If you don't have a .1uf cap, when you go to upload your sketch, hit the RESET button when you see the binary sketch size show in the compiler output (bottom half) of the Arduino IDE window.

  • I bought this Serial LCD display from Microcenter for my Arduino and ended up playing around with it in Windows using LCD Smartie and it works pretty nice. In order to drive the LCD display, you will need to purchase a FTDI breakout or cable that also provides +5VDC

    I'm using the following: LCD Smartie: http://lcdsmartie.sourceforge.net/ Fryar's Sparkfun SerLCD driver: http://lcdsmartie.fryar.org/serlcd.php FTDI Breakout: http://www.sparkfun.com/products/9716

    Connect the Red lead to +5v on the breakout, the black lead goes to GND, and the yellow lead goes to the TX pin of the breakout (Breakout TX to LCD's RX).

    Fire up LCD Smartie and in the right hand corner, specify Sparkfun.dll and adjust your comms. parameters as needed. Restart Smartie and it should work.

    The only down side is that the driver won't always update if you're actively making changes to the "screens" that LCD Smartie shows. To fix, just restart LCD Smartie after your changes and you're good to go. This is a pretty cheap solution to giving a headless server a LCD display for stats monitoring and it works very well. The only way it could get cheaper is with a parallel port-based HD44780 display of the same size.

    Alternatively, if you are wanting to just play around with the LCD itself and you have an Arduino but no spare FTDI chip, you can do this by putting the Arduino into shutdown (load an empty sketch) and then attach the yellow lead to TX on the Arduino (pin 1). This will allow your computer to talk to the display using the FTDI programmer as a simple serial port to try it out.

  • I have this kit and it does work however that LM317 gets hot as all heck, even under minimal load. I grabbed a cheap heatsink to place on the LM317 to help it ditch the heat without dying.
    As for the LED, save your eyes, do NOT install the red water clear LED. Grab a diffused LED from your parts drawer (you know you have some) and use it instead.
    Aside from the heat issue on the reg and the LED that I was quick enough to avoid, this PSU now hangs off the end of my breadboard and does a very good job.
