I am still working on the scanning algorithm. To make sure it doesn't twist wires, Eventually you will be able to initiate a low-speed initial scan. In this mode it finds start and stop angles for each ap detected. It is possible to have multiple starts and stops depending on antenna.
Next it optionally shows you a plot of signal strength vs heading. and allows you to select access points.
I need waterproof enclosure, high torque servo, arduino with 2 axis mag board, usb hub, and 4 way slip rings for usb. So do the math on cost and let me know how much. Luckily same arduino can do much more, like aim solar panels
(next project) or electronically adjust windvane
(to steer compass
Also you need usb wifi
device, and external antenna (duh) but you needed that anyway.
Same rig can be used for webcams. I plan on programming it to scan horizon for anomalies and signalling alarm
. It is possible to detect ship lights fairly easily at night for example.
Also great way to look around outside from below. Like digital periscope.
Then triangulation, and eventually knowledge of signal strength vs time of day so it can more accurately predict (and plot) expected coverage areas. That way you might see an access point, but it is too weak, you know exactly where you can go (and possibly anchor) that it will work
and at what hours. This mode requires gps and boat
movement, and some learning
