Go figure...
Jul. 23rd, 2009 08:05 amI've found that it's rare for electronic device power supplies to be labeled in such a way that one can easily tell what supply goes with what device, so for some time, now, I've cranked up the label-maker every time a new power supply is unboxed, so as to be able to match supply to device after, say, a move.
A few months ago, the archaeological dig that is our garage came up with a D-Link DCS-900W wireless digital camera, with a power supply that I had labeled accordingly. Yesterday, I set the camera up, thinking to get it working and then mounting it out front to help me keep an eye on things, when I noticed that the camera had gotten uncomfortably hot.
That can't be right, I said to myself, and unplugged the power supply. I looked at the labeled supply, and noticed its output was 12 VDC, positive tip. The little visual aid on the back of the camera was for 5 VDC, positive tip.
Huh?
Then I noticed the power supply carried the Linksys name (which is about as much information as one can expect on such a device, as it is likely intended to work with an entire line of Linksys products).
My bad, but then, where is the power supply for the D-Link?
Don't tell me...
Yes, the router for the house has been running on a 5 VDC power supply since... at least the time the camera disappeared into the archaeological dig that is our basement.
Maybe that explains what appear to have been occasional dropouts in wireless connectivity to that router?
Mind you, just occasional dropouts, noticeable, but not to the point of annoyance. Otherwise, the device just works and allows me to link to it from anywhere in the house.
I've swapped power supplies on the router, and may have a go with the camera when I have a free minute (and after I find or download the instructions on how to set it up, assuming I haven't burned the poor thing's innards to a crisp). Still... it's curious how well the router has worked at less than 50% of its rated supply voltage.
Cheers...
