  • Product TOL-08967 | about 2 years ago

    When ever I want to try a new surface mount technique I use this kit: http://www.electronickitsbychaneyelectronics.com/DELUXE-SMD-LEARN-TO-SOLDER/productinfo/C6719/

    It has practice parts and a red greed led blinker using a 555.

    I used the flux pen to solder this kit. I licked it. It stayed wet long enough to do a few parts. It washed off easily. I used the dedicted toothbrush to scrub the board. Then the heat gun to dry and evaporate the water.

    I do prefer water based flux. No chemicals required to clean. And it does not become a sticky as the no-clean stuff.

    Some of you guys are looking for inductance meters.

    Here is one trusted in the ham radio community. http://www.aade.com/lcmeter.htm $100 kit or $130 assembled. But not smd specific.

    great stocking stuffer.

    Papa Smurf does bring up a good point. Why 0 ohm? Why not use a piece of wire?

  • Product PRT-08780 | about 2 years ago

    I would like to see a smaller version of this board. Just have the needed pins for the DB-9. Makes it more embeddable.

    I play with devices that put out RS-232, but DB-9 is an option. So a small rs-232/ttl converter would be great.

    What does this buy me over the $1.95 logic level converter, http://www.sparkfun.com/products/8745 ?

    This looks so nice. But I still have two comments. Please oh Please, just write a java app so can use devices like this on Mac or Linux.

    ??? Has anyone tested to see of the software runs under WINE? Not just run, but actually have the meter connected as well.

    Second. *.RAR, bad flashbacks. Most infected software I have downloaded has beed rar archive more than any other.

    Ok doodle’s command line failed for me. I finally got it programed.
    ./avrdude -c usbtiny -p m328p -U flash:w:/Users/mpechner/Downloads/Simon-v21-Firmware/Simon-v21.hex
    No need to the “-B 1” and -U needed.
    I used adafuit’s tinyUsb programmer using CrossPacl-AVR on the mac.
    Yes, the first one I built last weekend is fried. Double checked the solder joint against this second one. It looks good.

  • Product KIT-09882 | about 3 years ago

    Ok. I built a second kit. Still Fail. Even though the instructions say the 328 is preloaded, it does not seem to be.
    Looks good?

    Why the FAIL?

    avrdude done. Thank you.
    I’ll say the bad thing. Will customer support pay attention to this post?
