Harald Molle replied to Adam Day's discussion Dual thrusters - ESC and PWM issues in ArduBoat User Group
"Nice to hear that it works! Adam Day said:
Great. Thank you very much Harald. 

This solution worked really well and I learned a lot in the process.

Harald Molle replied to Adam Day's discussion Dual thrusters - ESC and PWM issues in ArduBoat User Group
"OK, 
First, you will need 
- two diodes (e.g. 1N4148, wired types, no SMD)
- two resistors 1K, wired 

connect the diodes on the side marked with a bar together (the cathodes).
Connect  this side of the assembly to the PWM Signal that comes from the…"

Harald Molle replied to Adam Day's discussion Dual thrusters - ESC and PWM issues in ArduBoat User Group
"Adam,

i think, the ESC with the broken Fuse will pull the PWM SIgnal somehow to ground. An easy way to isolate the two Signals is a "wired OR" built with diodes. Because the PWM Signals are not that fast, this may work.I have uploaded a pic with…"

Harald Molle replied to Richard Sterling's discussion Boat zig zaging in AUTO in ArduBoat User Group
"David;
you may be right. I used my own autopilot software based on the very first implementation on ArduPilot. 
I don not know about the NAVL1_PERIOD. I assume it has to to with the update rates.
My problems with zigzaging reduced drastically by:…"

Harald Molle replied to Richard Sterling's discussion Boat zig zaging in AUTO in ArduBoat User Group
"I agree with Chris,
first try to reduce the P-Value. 
If this does not help, the construction of the boat should be reviewed.
I already had this problems with a monohull construction and a bad "center of gravity" due to wrong placement of the lead…"

"Sorry, got your friend request today, maybe the email went into my spam filter.
Yo may use a simply ARDUINO Board instead of the Ardupilot. I am currently using the ARDUINO pro Micro from Sparkfun, which is very similar to  the LEONARDO."

Harald Molle commented on Carl Stiegler's blog post First try on a (boat) drone for depthlogging
"Welcome on board!

I nearly have tried all possible alternatives for a boat:

monohull:

- bodyboards
 - styrofoam sheets
- model boats

catamaranes made of
- PVC foam sheets
- fiberglass coated styrofoam
- PVC tubes in various sizes (75mm, 110 mm,…"

"Peter,

depending on what depth you want to measure, there are a lot of options...
A realy small one is the Garmin Intelliducer.

I already have used it, but you have to make a…"

"Great stuff!
Fantastic vizualization, without any boring power point stuff.
I like it.
Thanks a lot  "

"Hi Northstar,
to make it short: No
But: 
- I have ported the code to the ARDUINO Leonardo, which is also OK and absolutely adequate for the job.
- APM is fine, but you will not need all the features.
- My design concept was to keep the code as…"
