I saw this at amazon and see it as a 'more efficient' version of a cigarette plug as most everything runs off USB now...

http://www.amazon.com/Cycle-Sounds-U...793450&sr=1-23

However, I will not pay 150.00 for something that can be replicated with assorted walmart parts for $20.00

After Googling around I found this thread: http://www.cbrforum.com/forum/showthread.php?t=96467
Which shows how it can built into the bike for very cheap.

Here is the parts list from radio shack:

Cables To Go 13403 Motherboard Adapter with 2 x USB Port (optional... see below for the waterproof connection)
Catalog#: 55010626
$8.99

SPST Flatted Metal Lever Toggle Switch (Optional... so it can be run to the battery and left hot or not)
Catalog#: 275-634
$2.99

+5V Fixed-Voltage Regulator 7805
Catalog#: 276-1770
$1.59

minus some wire and heatshrink and an in-line fuse, it is like a $20-30 project.

I can see building this into either the spedo console or the metal wind deflector around the headlight (opposite the aux flood lights)

As an alternative to the USB motherboard ports, there are these that will provide a waterproof connection:

Specifically this one: http://www.usbfirewire.com/Parts/rr-211300-10.html
and the matching cable to connect to your device, most likely this one: http://www.usbfirewire.com/Parts/rr-211320-07-xx.html

Even with the waterproof cables, it is still cheaper than the Kury powerpod, and waterproof and look better and not be hanging off the handlebars.

Once I get my parts in I'll post pics.

The basic idea is that you run 12v and ground to the voltage regulator, which down converts it to 5v. Run the 5v and ground to the USB bulkhead. The only real engineering is mounting the bulkhead USB connection, the optional toggle switch and mounting the voltage regulator in contact with sufficient metal to act as a heatsink.













It wasn't as hard as I thought it would be to mount it all... I tapped power from the battery line that went to the center console (on/off/acc switch) and a ground line from one of the wiring harnesses in the center console.. so everything is self contained inside the housing.

I am thinking about replacing the SPST switch with a SPDT switch, so I can select On-Batt, off, On-Acc... but I'll see how inconvenient it is having to turn it on/off everytime I choose to use it.

I'm also thinking about installing a power LED on top of the console to "remind me" if I have it turned on or not... it is only a hole and a $2.00 LED with holder that would be connected in parallel to the line between the switch and the regulator chip.. a 5 minute job.
