Sorry about the delay. Unfortunately I do not have any footage, and I haven't gotten it in the water yet. It was good enough to make out what things are, but as for being good quality, well it was only 144p at I think 15 Fps. 15 Fps was fine with me, but I would try to do full screen on 144p, and wh...

rossrov: Hmmm... that ethernet switch actually sounds like the way to go. I don't know much about them, but am I correct by saying it takes multiple ethernet inputs and sends it out one (providing there's enough bandwidth)? And yeah the teletext is pretty much what I was going originally thinking of...

The video latency is reported to be low, ~.4s, but I cannot verify that because I currently do not have the camera module :roll: . The Pi does have an I2C that will work with Arduino, and there are multiple projects out there that have used them together. The Pi is harder to use IO/PWM on, because i...

So after a lot of research, I have found I can use the Raspberry Pi for 1080p 30FPS Full HD video, as well it can take in the sensor data from the Arduino. The sensor data should be an array of 13 or 14 doubles, and sent every 30th or 15th frame. Does anyone know of a way to send the video feed and ...

It seems we have access to sensors that are good enough for our purpose. However there is noise in every sensor, and we have to apply a filter to it. One of the more popular ones is a Kalman filter. I'm also looking at this IMU from PNI. They have it preloaded with their own algorithm (Wish I knew w...

I honestly haven't tried it yet because I haven't bought the board, but check out my ramblings :lol: on how to figure out navigation for an IMU viewtopic.php?f=16&t=1374 . There is more than one way to do the math for navigation, but I think I'm going to go with the calculus route because it is ...

I brought up the spec sheet for the components on that board, and the accelerometer measures about 125 LSB/G at 4G(I'm assuming that's the max we will experience) detecting inclination changes of 1°, giving me precision down to the milli-G, and the gyro measures 14.375 LSB/°/sec, giving accuracy to ...

I've been doing some research on IMU's and (now all in theory :lol:) : The accelerometer should work in any water conditions. Have it start running on the dock (not a floating one) so we have an initial velocity of 0. Integrate once to find velocity, twice for the distance traveled. If the accelerat...

Been doing more research into this, and this is how it would work: 1. Using a GPS , get the (almost) exact latitude and longitude coordinates. May have to wait a minute or so after turning on to get a lock. 2. After getting a lock, turn off the GPS, and turn on the IMU , which consists of a 3-axis G...

There are FO transceivers that do specifically ethernet, all circuitry for media conversion included. I have not completely read through the spec sheets for those, but they are basically the same as for TTL, just different pinouts. Again that's definitely something I have to check with one of the te...
