  • Yup. And even though soldering headers on usually isn't that hard, it's still tedious, something to be done only if the board didn't come with them (or came with the wrong shape of headers, whether that's male/female or straight/right-angle or whatever.) For prototyping, plugging a wire into a female header is trivial, or plugging a male header into a breadboard (though that's becoming much less convenient as products go to 2xN headers, but you can still plug a cable onto them.)

  • At $DAYJOB, the IT department supports 32-bit Win7, so it's limited to 4GB. Therefore I don't use Chrome very often (burns way too much RAM), and do most of my work on Firefox, with IE8 as the default browser so corporate apps that only work on IE can run.
    On my Android tablet, I run about 4 different browsers - each have their limitations (e.g. Chrome doesn't seem to like Twitter's t.co or some of the other URL shorteners.) Also, I'm using Tor, which wants to have a separate browser app. On Linux, I mostly use Firefox.

  • Any chance of building these or the slow-changing ones into a Lilypad sew-on LED package?

  • Of course the industry people aren't creating the panic - we're running around like chickens with our heads cut off testing everything we can to make sure it'll either work with IPv6 or work behind a firewall where it doesn't have to use a public IPv4 address, and trying to find which pieces of equipment say they'll run IPv6 but actually run a lot slower if they have to do very much of it. (For instance, that firewall over there is using ASICs or FPGAs to accelerate IPv4 pattern-matching but uses the CPU for IPv6 or fancy tunnel protocols, and the CPU is three years old so it's only dual-core instead of 8-core.)

    And we really needed all the bloggers creating that panic just to get this far.

    And thanks to Sparkfun for a nice article - I mostly think of you as dealing with equipment where we don't care about IPv6 addressing, we care about "solder the LED to pin 12" or at most "the board talks USB to the PC, and the PC uploads the software to a website." One technical correction, though - you still need services like DHCP, whether it's DHCPv6 or the Router Advertisements that work along with the EUI64/MAC-based autoconfiguration. And most servers will still get their host address manually assigned so it looks like ::1 instead of ::64-ugly-bits.

  • Most websites will have IPv4 addresses for years, and also have IPv6 addresses. Most of your home devices will support IPv4 with NAT and RFC1918 private addresses for a long time, and the computers and a few other things will also have IPv6. One of the big issues is that many home routers / cable modems / DSL modems don't support IPv6, so the broadband companies haven't been pushing really hard to retrofit IPv4 users with IPv6-only service, though the ones who can are pushing towards solutions like "IPv4 with Carrier Grade NAT and IPv6 with real addresses." There are a bunch of different flavors of IPv4/IPv6 tunnelling and NAT solutions that carriers and end users are using to glue stuff together.

  • Apparently LiPo batteries get really grouchy if you let them discharge below something like 3V (as well as needing special chargers, but you've obviously got one of those.) Is there any easy way to design a circuit to cut the things off if the battery's discharged too much, or do you just have to guess, and recharge it while it still works?

No public wish lists :(
