Sorry if this is such a newbie question, but on the topside connection with the homeplug and the controlling computer, is a router necessary to connect the homeplug tether too, as well as the laptop, or do people connect the homeplug directly to the laptop and have the laptop 'Internet connection share' with the Beaglebone?
Having a router seems troublesome in the field, as it needs external power.
But my wonderful little new laptop does not have an Ethernet port (Lenovo Yoga 13 with Windows 8). I could get an RJ45 to USB adapter, does anyone know if this will work, to hook the homeplug up to an RJ45 to USB and connect the Beaglebone to the laptop this way (with no intermediary router to assign ip addresses, etc.)? What methods are people using?
While pondering all of this, I thought if I had a spool that had the homeplug adapter, a 18volt battery, and a wifi to rj45 dongle, one could make a tether spool without a slip ring necessary, just contain all the electronics in the center and let them rotate with the spool as it pays in and out. The battery could send voltage down to the OpenROV, which could then not have need for onboard batteries. (the voltage drop of 18v through 300 foot tether would be to about 12v @ 1amp draw) This is what I found of interest to power from the topside http://www.amazon.com/20000mAh-External-Capacity-Netbooks-Notebooks/dp/B00B45EOYS/ref=pd_bxgy_cps_text_y , seems it has enough juice to power the rov and the wifi dongle and topside adapter and is easily recharged.
