    Can I connect this to an Arduino Ethernet? Are the pins in the correct places?

    Nevermind-I found it: whichever way the green power LED comes on. Hah!

    I am at Starbucks and don’t have a multimeter with me. Which way does the 6-pin connector go on an UNO?

    It’s great to see somebody pursuing his passion and becoming so successful. Congratulations and keep on going!

    So I can’t use this shield with an off-the-shelf POE router because the router provides 48 volts, and expects a negotiation protocol? How much trouble would it be to add this capability?

    This experience epitomizes how lawyers and scavengers are ruining this country. You can’t even give something away for free without worrying about a lawsuit. The people who create things and are productive are circled by lawyer vultures who have no regard for ethics or any greater good.

    This programmer worked flawlessly for me, using Ubuntu 11.04 and the avrdude method to burn an Arduino Uno bootloader. One little note: you have to be in super user mode, so the comands are:

    sudo avrdude -b 19200 -c usbtiny -p m328p -v -e -U efuse:w:0x05:m -U hfuse:w:0xD6:m -U lfuse:w:0xFF:m

    and

    sudo avrdude -b19200 -c usbtiny -p m328p -v -e -U flash:w:optiboot_atmega328.hex -U lock:w:0x0F:m

    I don’t know how to tell the Arduino IDE to issue an external command in super user mode, so I can’t use the IDE to burn. However, now that I got the command line method working (3 minutes after unpacking the programmer), I prefer the flexibility of specifying the hex file anyways. Great device. Previously, I spent two weeks trying to burn the bootloader with the “Arduino as ISP” method, but with this device, it worked right away.

  • News - The Slap Method for Solde… | about 2 years ago

    Good idea-I’ll have to try it some time. I’ve had good results with a desoldering iron for about $20. It has in one tool a heating iron and a vacuum bulb that you squeeze before you heat up the solder, then let go to pull the solder out of the hole. Sometimes, the hole is stubborn-just add some fresh solder to the hole and vacuum again.

No public wish lists :(
