Stop promoting this stupid and dangerous idea!GChriss wrote:There's some truth to this one -- I was able to partially power the Model B board using a 3.5mm stereo male <-> dual RCA male cable, no other cables (i.e., microUSB, Ethernet, HDMI) attached.
'Partially' powered means the cables were sparked against a 5V USB power source resulting in partially-lit LED power lights. Some real soldered connections and we might be in business.
It isn't undervolting, not unless it managed to draw all 2A from your supply through the 3.3V regulator and the audio protection diodes. I wonder if the 3.3V regulator can signal an over-voltage shutdown.GChriss wrote: -When running via 3.5mm jack power attaching the Micro-USB cable to a free-floating power adapter (e.g., an Apple USB Power Adapter) will cause the device to reboot due to temporary undervolting.
Will the madness never end?PoE
