I have not bought any of the parts yet because I'm not sure if every usb host works with a Bluetooth dongle. Also I'm not confident in building the one he linked in the video. I found one on Amazon and I don't know if it is going to work or not, but it looks the same. I found a Bluetooth dongle compatible with the program located on his blog. All I need to know is that Bluetooth dongles are compatible with any usb host. Sorry I was not clear in the beginning.
