    Anyone know where I can get a few thousand of these buttons? I love SFE for prototyping but ordering for small production runs doesn’t seem very practical.

    This will never work… just saying.

    SF Guys, this is important!
    You should really consider disconnecting the PS pin on the TPS61200 on the next run. The way you configured it currently power save mode is disabled. This means the switcher is operating at full frequency, even when no load is connected. This results in terrible efficiencies when no load is connected. The way this board is designed currently it WILL drain a battery within a week or so. I measured ~10mA draw from the battery when testing with no load on a circuit I implemented using these parts.
    This makes the product almost useless for data loggers and the such. Cutting the PS trace dropped idle power consumption down to a microamp or so, where it should be!

    Because we should limit the availability and spread of knowledge due to fear of it’s misuse…
    Projects like this are breading grounds for future world-class engineers and intelligent individuals in general.

    I did a short writeup on installing this under Windows 7 x64. Hopefully this will help you guys out:

    Mine smells funny when I plug it in and charge. I’m using a 9V power supply. Normal?
