  • For instance if you were to use a alkaline battery you would have a higher temperature output of about 600°C (peak) with a much shorter battery life but if you use a nickel-metal hydride type you could only get about 400°C but with a much longer battery life.

    Or you could use Energizer L91 Lithium/Iron Disulfide cells and get BOTH performance and high capacity.

  • I see nothing on Mouser except “on order”.

  • Before somebody else does it for me, let me freely offer that my comment was stupid. The connector I mentioned would be way too gigantic. Would a micro USB fit on the power pads (for power only of course)? I’m afraid it would tear off too easily though.

  • This block would make a lot more sense if it included a 5.5 mm barrel socket for power from a 5v brick; even better a provision to alternatively add a LiIon for power with charging from either the USB or the 5.5 mm socket. Maybe that would be escalating the scope too much.

  • Too bad this doesn’t have an adjustable low voltage cutoff. It looks like it’s capable of way overdischarging a single NiMH cell and would be a lot safer with a cutoff set to around 1.05 volts. There ain’t much energy left in a NiMH if you discharge it below that level, but it does a lot of damage in terms of shortening the life.

  • Just wanted to report, I compiled a gcc cross compiler, and lpc2k_pgm, on linux from current source code. You have to grab appropriate C startup code and a machine header file from WinARM or somewhere, and then it’s pretty painless.

    I did run the Coridium software in VirtualBox under linux to initially check out the board and play with it.

    Really nifty entry-level board!

  • 3.7 volts is only “nominal” and is misleading. A freshly charged Lithium Ion or Lithium Ion Polymer cell is 4.2 volts, XBee spec is 3.6 V, so yeah if it was me I wouldn’t try to run them directly off the cell.

  • Why is the system calling me “madashell?” I’m not mad :-)

  • I don’t give a crap about an IDE, but would appreciate a pointer for developing on linux. Something more helpful than “use gnuarm.”

  • I dont feel the need to be civil to these monsters, and this captures my carefully considered reaction perfectly:
    SparkFun on the other hand, you’re a classy outfit and valuable resourcfe.

No public wish lists :(
