Hey guys wondering about a ghetto sensor bar solution

[Murchyman]

Hi guys i'm buying some stuff to get into wii emulation and was wondering if it's possible to skip out on the dolphin bar by modifying an existing sensor bar? Additionally what are the chances that this http://www.ebay.com.au/itm/Mini-USB-2-0-Bluetooth-Dongle-Wireless-Adapter-For-PC-Laptop-Notebook-Win-7-8-XP-/291731630078?hash=item43ec8f67fe:g:tqYAAOSwsN9XBlFt is legit and do you guys have any ultra cheapo Bluetooth adaptor links?

thanks, Murchyman
