Just Awesome Laser The speeds are stunning, need to go look for an old laser before the price goes up....
For a laugh here is a 50 sec video of my DIY design driving a sport boat in frisky conditions: http://www.youtube.com/watch?v=EWObyejTb3A
BTW, I have done two versions of an HBRIDGE that can drive 10 amps or possibly more (I am using it up to 10 amps currently). I am about to release...
PID implementation: Sample rates of a 1/10 to 1/20 of a second are more than adequate. Reduce the bandwidth as much as possible to eliminate...
rate gyro's ? Are you using rate gyro's ?
Rasberry pi & CMP 10 display Arne, I assume the display your showing is on a PC screen and not a cell phone ? The display looks good. My...
AP using iphone Great concept. You dont really need compass accuracy, you need repeatability. At least that is the case of the unit I have...
AP solution Hello Jeb, I have built an AP from the ground up and it is now on several sail boats. It sounds like your interest is in the...
Hi Dave, I would agree, the issue in the phones are the algorithms in use. I have had several phones (2 iphones and now a samsung), after...
One other comment, you might turn on your cell phone compass and pass it through roll and pitch motions. The results are much less than...
Dave911, To clarify what I stated, I have been using sensors that are used in the cell phone industry, but not the cell phone itself. I have...
Kipper: You can make one work with the same processor as used in the Arduino UNO. I have based my design (see entries above) on the same...
What CDK said, only you can still use the fluke and take about 10K ohm resistance and place across the fluke leads when making the voltage...
Thanks for photo. Two questions: 1) Do you really use the stainless shackle as a fair lead for the drive cable ? 2) Ever get your toes caught in...
current drain. another measure I have used is the ability of 200watts of solar panel to keep up with the AP. During an extended voyage I noted...
Your drive current sounds very low, even lower than commercial implementations. I wonder how you are measuring current ? In my implementation the...
See >>> for answers: >> The gyro signals predict heading, that is they modify the much slower compass and keep a running DR heading estimate....
I would possibly agree. The exception is the quality of the compass. I have been coding my AP for tilt compensation and using an iphone and...
Autopilot DIY Hi, Please see answers below: What did you do to merge your gyro signal into your compass heading in your software? >> The gyro...
Great looking design. How do the dagger boards clear the shroud attachment points ?
