Currently all components have been hooked up\/tested individually, and I've finally gotten them all (mostly) to work together simultaneously. The main challenge at the moment is that I'm drawing more current than I ought to, so I need to split the load up a bit. My electronics knowledge is not where it needs to be for a project like this, so I'm hacking my way through it! <\/p>\n

One very big annoyance related to all of this is that the micro-controller I'm using supposedly lets you split the servo power from the rest of the board by \"simply\" unsoldering a jumper. I hadn't been aware of such a thing as solder braid when I first attempted to clear the jumper, so I fear I have melted the contacts together.. I have since tried using braid, but it still seems to be connected, and I cannot see anything more than a single contact. So for now... I will try sharing the servo\/microcontroller power. If things don't work out, I can always fork out the $60 for a new micro-controller board and try again. <\/p>\n

Once my power issues are resolved, I can finally work on porting the navigation logic from my simulation to the actual board. The first step to that, however, will be to update my simulation to more closely match the sensor data\/configuration and use gps values rather than screen coordinates. For example, originally I had assumed I would know the wind angle, but as I may have previously mentioned, a mast mounted wind meter is not feasible on such a small boat. Problems with apparent wind are magnified when the mast is bobbing around in even modestly rough waters. Instead, I have opted for magnetic reed sensors mounted to the \"main sheet\" to tell me when the sail is powered up versus luffing. (I really only need to be able to determine if I'm in a head wind, and, if I care to, can determine wind angle by checking my compass). I will try to post more pictures and talk less as it's probably not clear from reading my explanation. \ud83d\ude09<\/p>\n
