Hello,
I just bought a fantastic Teensy 3.0 and I am playing along with IMUs and it works perfectly, thanks!
Besides IMUs, i am playing with Teensy and addressable RGB LED strips, as I have 10 meters of the following leds:

If my calculus is correct (0.25watt per LED, 70 leds per meter, 10 meter) i have to provide 175 Watt.
Given that is correct, i have to suppy that energy to the leds.
My questions are:
Can i just supply energy to the Teensy by the usb cable (the usual .5A), and supply energy to the led strip (175Watt)by an external (stabilized) power supplier?
Or do i really need to separate the VIN from the VUSB on the Teensy board? If i am correct, this means also that the Teensy is not powered anymore by the usb cable, but only data will pass on the usb cable.
If I reallly need to separate the VIN from the VUSB, well, my question is: how to do it? I have not seen any picture of a Teensy board where the VIN and the VUSB are cut apart. This procedure is briefly explained here: http://www.pjrc.com/teensy/td_libs_OctoWS2811.html
Thanks a lot for you support,
Luke
