Hi,

my friend would like to develop remotely operated ROV Patrol Boat or Catamaran, equipped with marine radar and sonar to supervise shellfish farms at night.

Are you aware of alike project ?

Patrol Boat or Catamaran should be 3m or up in length to handle all the equipment.

Radar imaginery should be radio, WiFi , 3G/LTE transmitted to the ground
control point.

Sonar should be remotely operated and image saved to SD card as well as wirelessly transmitted to control point.

Gas jet motor or electric powered.

Since such patrol boat operated at night should not generate noise, vibrations, I have suggested electric motor (2 electric motors for drive and to replace rudder).

This ROV boar should be operated in the lagoonas and water depth could be as low as 50cm so I have suggested airboat but it is very noisy in the Florida's Evergreen.

I would welcome your suggestions, remarks.
If you are aware of alike project please provide me with some links.

Generally speaking, what should be developed is
self-floating radar, sonar on a ROV boat and data should be accessed remotely.

ROV Patrol Boat should be operated 24h but special attention is paid to operations at night in the lagoons.

thank you

darius

After 15 years of using 2 cordless keyboards & 1 cordless mouse, finally switched back to an old fashioned corded setup. The constant battery deaths would occur in the least timely moments. The radio integrity was random. The range wasn't long enough to truly be cordless. The mouse speed would change randomly, after changing batteries. The return to corded input is like returning to 1999, an easier time. It always worked, but there was 1 problem.

The pointer speed for PS2 mice always worked in Linux. For USB mice, it never worked. xset never worked as documented. Always stuck with a 15 year old mouse with a PS2 adapter, even after its scroll wheel stopped working & it randomly jumped around on a new mouse pad.

Linux has gone now through a dozen attempts to control pointer speed for USB mice, none of which have worked. They've tried changing xset, xinput, gnome-mouse-properties, gpointing-device-settings, xorg.conf, 50-mouse-acceleration.conf. The only foolproof way to configure the mouse has been recompiling the kernel. This too migrated from a change in drivers/input/mousedev.c to drivers/input/input.c several years ago. After years of editing mousedev.c or just using a USB -> PS2 adapter to force it to use the old PS2 driver, here is the change to input.c to slow down the mouse:

inside

static void input_handle_event(struct input_dev *dev,
unsigned int type, unsigned int code, int value)
{

add

#define DOWNSAMPLE_N 100
#define DOWNSAMPLE_D 400
static int x_accum = 0, y_accum = 0;


Then after the switch statement:

case EV_REL:

add

if(code == 0)
{
x_accum += value * DOWNSAMPLE_N;
value = x_accum / DOWNSAMPLE_D;
x_accum -= value * DOWNSAMPLE_D;
}
else
if(code == 1)
{
y_accum += value * DOWNSAMPLE_N;
value = y_accum / DOWNSAMPLE_D;
y_accum -= value * DOWNSAMPLE_D;
}

At the AMA Convention I purchased a VQ Dauntless and started working on my review of it then my bud John comes along and wants me to work on his NIB 1/4 H9 Cub....so I'm at a crossroads....

I started on the Cub, mounting my DLE 20 (he purchased a 35RA which I think is too much engine for him) and after a day and half, I finally got the engine mounted. Those blind nuts are a pain to mount...

Meanwhile I will have to order ten (10) servos for the Dauntless...I guess James at JB Hobbies will be getting ALL my money

Notice the Cowl is cracked don't know if I can match the paint...

Yesterday I visited another club's WarBird Fly-In...some NICE planes there!...Continue Reading

Passage into the new year has brought some changes. Still about 16 felines hanging about, 9 or 10 regular indoor visitors but some have moved away and some have found our little niche' anew. A note by Mark Twain on felines: Of all God's creatures there is only one that cannot be made the slave of the lash. That one is the cat. If man could be crossed with the cat it would improve man, but it would deteriorate the cat.

The following is a small sample of pictures I've managed to snap. Lots of play time, day and night. Also, regular attention to two litter boxes and keeping food and water. I've arrived at more and more kindness to deal with them, all with different personalities. And, we've managed to spoil a couple along the way....

Can't leave out our taking in a 'possum or two for baths (lice and fleas). Farah was very well behaved and enjoyed it mostly. Good shampoo, not a sign of new infestation afterward.

Sadly, our dear Mumbles - the little orange/ginger molly - died early in the summer this year, peacefully under the bed. I found her in the morning, her last sleep with us. She always had a touchy bowel with more than the usual barfing for a cat and I suspect it was some trouble there that eventually went wrong.

I have modified one of the earlier Durafly P-40N prototypes I had gotten from Stuart Warne at Hobby King to accept these Landing gear units. They offer the same 100deg forward rotation with the 90 twist to stow flat in the wing like the P-40 and F4U.

It is quite a bit of work as these are far from being drop in replacements for the stock solid strut units. But if you are interested in repeating this, keep reading.

You will need:
a dremel tool and a 1/8" router bit.
a disk or belt sander
3/16" (5mm) wood dowels
#2 sheet metal screws.

Let's get started.

Though I'm not an FPV race guy but rather hovering instead of fast forward flying, I decided to build one together with a friend.
We took all parts for the basic setup from the Flyduino Shop as it offers almost everything needed.

KISS FC RCG Thread
KISS FC Manual
KISS FC Chrome APP
KISS FC Update Instructions

KISS ESC24A RCG Thread
KISS ESC24A Manual

KISS PDB for 24A Manual




We already had a few peripheral parts like the FPV cam and transmitter, lipos and RC receiver.
For a start we used an FrSky 8channel PPM receiver and a Taranis.
The X4RSB 3 receiver offers both S-Bus and S-Port (for telemetry) which we will use later.


The build consists of the following parts:

- Warthox MiniCP120 with carbon fibre arms

- KISS FC 32bit Flight Controller

Hello!

I am new to this forum. My name is John K. and this is my first post. I am completely new to the quad-copter and R/C hobby. I came on here to learn more about quads, pick up tips for improving my flying skills, making modifications to my fleet, and to share what I've done and learned.

To that end, my along with my first post is my first mod.

I received a WL Toys V666 FPV camera drone for Christmas. It's a fun flyer with a crap camera and even crapper FPV. However, It works for me now and I have future plans to progress to better machines to the end of doing 3D mapping to enhance my skill set for my job. After a few hours with it I noticed that the foam ring limits the performance of the craft, so I wanted to take it off. I found a YouTube video by Quadcopter 101 and did the mod he suggested. My only addition was to slide a wooden dowel thru it and secure it with a rubber band. I lost a rubber damper yesterday and I will be getting some extras very soon.

Thank you Quad-copter 101 for posting your helpful video. The flight of this thing without the foam ring was remarkable better.

Hey there, im making a project on composites. I have taken balsa wood and would like to illustrate a bridge out of it. Since the topic revolves around composites, i would like to reinforce it with carbon fibre to increase it strength. Hope to see u guys coming out with great ideas and helping me out

Hi Guys well the Spirit pro came still waiting on the servos but started set up , took a bit of messing to set up throttle as the Castle wants one setting and the Spirit needs another
Well all done now and I am all 3 head speeds working helped by Steve
so once the servos come the real set up will start
Dry lube stayed put when heli was started up so thats good I wanted some bearing oil for the scorpion motor well its like rocking horse poo
in the UK so I got some Heli Option bearing oil which is ment to be good
The optipower is fitted and ready to go

I can't believe that I forgot all about buying this little micro quadcopter a couple of years ago. I ran across it in the box of stuff at home when I was looking for something else to use. So I pulled it out to finish it up and get it going. I think it will make a great micro FPV platform, even with brushed motors.

Hobby King sold them at first as a semi-ARF kit. You had to mount the motors and solder the motor wires to the frame. Later they started selling it as a bind and fly kind of unit. So I don't know if they still sell the kit version or not.

Putting it together wasn't a big problem. I did need to use a jewelers file and carefully make the motor mount holes just a touch larger to fit the motors as the motors wouldn't squeeze into them.

Granted soldering the motors to the frame is a bit tricky as the wires are so small. But I used a desktop magnifier to help along with a pair of tweezers too.

The little quad uses a Multi-Wii flight controller. So if one needs to, they can go in and change settings etc. I have not done anything along that route though with mine.

They seem to have shipped a number of the little quads with un-programmed or configured flight controllers. Or the little tiny surface mount MosFet transistors driving the motors are bad. So a person may have to get into the details more and setup and program the flight controller. If one is unlucky they may have to replace one or more of the MosFet transistors too.

Mine is apparently one...Continue Reading

At the beginning of the school year some of my old students asked if we could start a (FPV) Flight Club at school. They had seen some of my videos in class and wanted to join in the fun. Thus began our quest to build. I settled in on the ZMR250 using the SimplePDB by OSO. I will document my steps so folks can help with tip or students can refer back to see how to rebuild after a crash.
Step 1: Solder Supersimple OSD to board

Yesterday was great weather for January (0-5mph winds, 50-55F) so I was able to get out and maiden the GP Extra300 that Santa brought. Power is from the recommended electric setup with Rimfire 80, Castle 100 ESC, 2x3200mAh 3S batteries (series), and APC 15x7e prop. What a blast!
