    I’ve used many of these, some on data lines up to 75 feet long with no problems (I use phone RJ11 cables). My favorite technique is pulling apart phone union jacks, putting a DS18B20 inside the jack, and putting it all together again. I’ve daisy-chained up to 4 this way.

    Hi Jeff, Thanks so much for this awesome bit of work, it makes the difference between a hobbled curiosity and a useable tool for me. Hey, everything seems to be working really well for me with one exception. My z-axis accel consistently reads around +1700 at rest. Seems like an odd number (not 1g) and I know the output is supposed to have gravity removed. It responds as it should to movement (other than being off by 1700). Any ideas? Thanks!

    Hmmm, the datasheet says 25K to 125K ohms, the Quickstart says 30K to 50K, the Oomlaut Project says 10K to 35K and the one I got is 18.5K to 21.5K and not very consistent. It doesn’t seem to be a very reliable component.

    Can these be cut to shorter lengths?

    In addition to the other negatives mentioned by many (really hard to see holes, etc.), these things smell terrible. They offgas some sort of awful and probably hazardous smell that’s very chemically, solventy and it actually fills the area you’re working in.

    I know it’s been a long time since you posted this Dave and it seems to have helped a lot of people. I’m at my wits end with my attempts and wonder if you’d have any ideas. I’m using the Mini Pro, your code and the I2C Master library. My connections are good, using A4 and A5. I’ve tried pullup resistors and not. The code compiles and uploads fine. When it’s run, it seems to go into the I2C library and never return. The “Hello” command that’s really the only thing that happens early on in the code never comes out the serial port. Strangely, the indicator LED on pin 13 lights and stays lit, though I don’t see any code that would cause that.

    Any ideas would be appreciated! Thanks.

    If you’re planning on using the analog sensor pins you should note that the WiFly can only handle up to 1.2 volts, not 3.3. Seems like a logic level conversion is in order. But, you can set the WiFly to supply 1.2 reference voltage to a sensor power supply pin that could be applied to the low side of the converter. I suppose you could just use the 1.2 volt supply for some sensors but I think I’ll get 3.3 from elsewhere to supply my sensors and translate the output. Reasonable?

    Just bought one of these. The installed resistor is 0 ohms, so apparently that means it’s setup for 3 volts these days.

No public wish lists :(
