    Given antenna gains are volumentric functions, truly omni antennas are impossible at high gains.

    Current capacity is a volume thing. The pins on the IC typically have much more volume (height? depth? not sure what the right geometrical term is) than a copper trace on a PCB board will. For high power routing you will typically wind up with traces wider than the pin width with solder acting to distribute the charge from the pin to the wider trace.

    In the data sheet it says it’s reads pressure ranging from 50 - 110kPa. Using the formula provided on page 14 in the datasheet for pressure to altitude conversion you can use the 50kPa to find what the maximum is.

    Just found out these fit perfectly in http://www.mouser.com/ProductDetail/Hammond/1554F2GYCL/ if you’re looking for outdoor deployment. Despite the “Robust sealing for out door applications!” assurances, the exposed grounding pin leaves me a little weary.

    Rapid prototyping vs designed to be used in finished products.

    Are you sure? Even my 1.5 watt 445nm is usually pretty visible. I’m sure it’s just bouncing off dust… but it’s still there. I’d bet that the SparkFun build labs is pretty particle heavy ;-).

    For those who don’t want to RTFM, it’s 50 Ohm (audio) not 75 Ohm (video). I only mention this because I pulled some 75ohm bastards out of a parts bin while working on a high speed, 50-ohm senior design project and spent a few hours fighting some uncalled for reflections.

No public wish lists :(
