General Hardware Talk / Sensor bar questions
« on: March 22, 2008, 11:01:09 AM »
I noticed that the wii sensor bar has 10 LEDs.

5 on each side. in this configuration /|||\ almost like a fan.

Reading on the web I also found that the wii sensor bar uses 12v from the back of the wii (very much like firewire).

In our class project, we're using the wiimote to control an interface written in java. Ideally, we'd like it to work from about 10 or 12 feet on a couch.

My question is this:

when building my sensor bar, should i try to mimic the sensor bar as much as possible? (10 LEDs and 12v power supply)

I've got 4 of the 276-143 LEDs from radioshack right now and can get another 6 more without issues but i'd like to stick to the standard USB 5v.

Will 4 LEDs be enough?

Also, instead of destroying a USB cable, I was thinking about purchasing a 5pin mini usb female connector and use that on the sensor bar so that there is more flexibility on the power source. I can use my laptop for power or use a blackberry phone charger that plugs into the wall.

Any thoughts?
