    I wouldn’t mind seeing this product come back too. I have several projects that are based on this fob and if it breaks, I wouldn’t be able to operate them. I wonder if there was too much technical support for it or there were quality issues with it. I know my first one had to be returned.

    This is a great little tool for programming AVR MPU (or others) after they’re wired into a circuit. It would be nice to have a 3.3v version of this or an in-between board that would convert the power and signals to 3.3v. Some circuits I’ve built do not have 5v tolerant parts.

    Even better would be one that supports 1.2V, 1.8V, 2.4V, 3.3V, and 5V. A little header with jumpers to select the resistors used for an adjustable regulator could do the trick. That might be cost prohibitive prohibitive though.

    Thanks for providing the graph.

    People have been asking what resistor to use with 3.3v. I’ve been using a 220Ohm resister to limit the current with a 3.3v supply. The voltage drop on the resistor is a little over 0.5v and the current is 2-3mA which is about right for your graph. I think this is safe for not burning the LEDs. It provides plenty of light when you need it and doesn’t drain the batteries too much.

    It would be nice to have a version of the Arduino with this included (maybe they’re working on it). I have lots of projects that would not use the feature and don’t really want to pay for it. I don’t think it should be standard.

    You can always pop and Arduino mini into the prototyping area.

    I like the ideas presented. Someone cold easily wire any of the Arduino’s outputs to a thu-hole going to pin 3 of the Hex converter for the CSN. If Sparkfun concerned about having a board that works out-of-the-box, then maybe have a surface mount jumper/resistor that can be removed to disconnect it from pin8.
    Another big advantage of having the SD pins broken out to thru-holes is that other 3.3v SPI devices could use the converted SCLK and MOSI pins. It would also be nice to have the unused lines on the hex-converter broken out to thru-holes too. We could use those for other 3.3v devices…. although, someone with a decent soldering iron could probably wire straight the pins.

    I have a Tower Hobbies Servo (made by Futaba) and the armature fit the shaft of this servo. Also, I look around on the web and it seems it’s the same as Futaba output shafts (i.e. 24 tooth spline)

No public wish lists :(
