  • “Note: Due to the manufacturer’s restrictions in other countries, we can only ship these to the USA and Canada.” This is why I now actively avoid Digi products. Anything Digi seems to be accompanied by a cloud of confusion. I have found their website, product structure and documentation … unhelpful. And then when you locate what you want, nobody knows about it or refuses to sell it to you. Also my local Digi supplier (BB Electronics) suddenly dropped Digi recently (suspect they were having problems also).

  • Since pretty much all modes of long distance transport burn oil (in one form or another) [1] why not use transport costs as a means of calculating your carbon foot print. Transport companies don’t operate at a loss… else they won’t exist. But let’s put an upper bound on this by assuming that they spend 100% of their fees on fuel. So assume crude oil is $100 barrel, and you spend $1000 on transport, then that’s 10 barrels of oil. I believe that’s approx 0.5 tonnes CO2 / barrel [2] .. so 5 metric tonnes of CO2.

  • For UK/Ireland you should talk to Maplin (http://www.maplin.co.uk ) a Radio Shack clone with retail outlets in most towns. They could badly use some fresh modern kit to sell. This is their idea of a PIC programmer: http://www.maplin.co.uk/pic-programmer-48074

  • I just started to use two of these boards a few weeks ago. A curious thing has happened in the past week: the power LED (next to the mini USB connector) on one started flickering a few days ago and the LED no longer illuminates now. But the XBee and communication to/from the XBee seems to be working OK. The power LED on the second board is flicking also but remains mostly fully illuminated (for now).
    Both devices are powered from a USB hub (powered from the PC). I think there is plenty of power available – I don’t have any problems with the other peripherals on the bus.
    I’m hoping this is just a dud LED or LED resistor and nothing more serious.
    The date on the PCB is 10-8-08.

  • Can you include a scan/photo of a sample print from the device?

  • Is anyone making open hardware kits for these? If someone sold an entire kit (structure, motor, battery, controllers, wireless rx/tx, camera, GPS, IMU etc) and a reference design I’d probably buy it. The Parrot AR.Done looks nice, but I am put off by the lack of Android support. And I’d prefer to make my own.

  • I saw an interesting application of those iButtons recently on TV: it was being used to measure an elephant’s core temperature. They would feed the animal one of these things (embedded in a lump of wax) and pick it up a few days later in the poop.

  • Goes to show that when you leave the lawyers out of business and engineering the world works a whole lot better.

  • The addition of a real-time clock would make this perfect for some apps I have in mind. Even if the clock’s only function is to put a timestamp on the log files.

  • Wondering can this be modified for a computer port? The A, G, C, D, V connections on the bottom of the PCB look interesting.

No public wish lists :(
