Really nice Daniel!

Congrats, impressive work!

Did you also design the adaptor box for connecting the head and the cam?
How far can you use the cams with CAT5? Up to 100m? I never went further than 75...

Bien à toi
Guillaume



250 Feet =
76.2 Meters
i have to test the real limit.... maybe more!
Yes the box is mine too.... hardest part is soldering the multi connector for Sony: so tinny!

For Bescor or LANC ? i do both.

I too have bescor controls and lanc on the same ethernet cable, so 75m/250 feet for both is my limit unfortunately.
The problem in my setup is I need USB to Ethernet adaptors. Cheap models allow up to 35/40m, the best I found so far goes to 75m.

Yes LANC over 2.5 jacks is much easier to weld I guess ! ;o)

I use Canon with 2.5 jacks for lanc and when I use Sony cams/dslr I switch to Wifi to control zoom

Do you extend the USB or CAT-5? Or USB over CAT-5 ?

I use Cat-5 because its convenient... out of my controler 4 wires for PWM/Bescor and 2 wires for LANC.. i got 2 free wires for future options...

Check this link http://expedition-electr.../pantilt/pantiltlanc.htm
This is what I use

my setup is:
laptop with software & gamepad > usb2eth > eth cable > eth2usb > PTZ controller > bescor & cam

And I need as many of all these adaptors for each bescor (I have 3)

This is really the cons of this solution but it's working great anyway.

I love your device with 4 integrated ETH plugs. I think you did an impressive device!

Thanks!

Now i understand your setup.... USB over CAT-5....

I may push my project as open hardware... i already have some extra PCBs if any interested...
i like to find a Arduino coder.... it's my biggest flaw, i did copy/paste a few projects i found over internet and it works, but i like to push the project and dont want to learn any more programming....

Spino who took part in this discussion seems to be an Arduino specialist. He's building an external switching control board with arduinos at the moment. You should talk together.

Keep us posted. This is very interesting.

Thanks Spino.

Yes I know about DIY projects for motorized heads with Arduino, I even tried myself with basic servo motors from a MEGA starter kit, but I thought you were talking about arduino projects specific for bescor heads which I never found yet.


DWAM

That was my starting point for Bescor control http://protechy.com/, i did the nunchuck version as described works great...
basicly Bescor original controller simply variate voltage for speed control... very bad for low speed!
The trick in protechy concept is to keep same voltage but PWM it....

For the LANC part... started with:http://controlyourcamera.blogspot.ca/2011/02/arduino-powered-lanc-remote.html

On top of it.... i2c OLED/keypad/joystick calibration

Lot of fun for a non programmer like me!


i should cleanup my code and share it.... opensource software and open hardware.... just need some serious documentation on my part!

Yes I can imagine! ;o)

Yes I had already visited this protechy website, but long before I started to play with arduinos, so I forgot about it!
Not sure I will give it a try anyway, this seems to be far beyond my skills and I'll be busy on productions soon until the end of the year (hopefully).

Again congrats to you! Awesome!

@Doggy

Guy, maybe that's why you have noise, because I never felt like Bescor heads were noisy

@DWAM

it's using PWM speedcontrollers , just on a higher base voltage (9v) level than the Bescor normally uses to achieve a higher panning speed
It's mechanical noise when at full speed , lower speed is no issue at all (typ of noticale if you know about it,or picked up by camera mic )
As mentioned before the motors are pretty weak , to fast and the constact strips bend over

Take a look here:

and here second part:


I think that it's a good point to start for wireless control of Bescor.

Not a really Arduino specialist. For my project I made some improvements of codes I found in Internet. By the way, the codes for my next controller are ready and they work. There will be two Arduinos Mega (one for buttons and potentiometers and the second one for activators to light the leds under buttons and tally lights). stay tuned :-)

My opinion about this build...:

i wont recommend using (Quote from his youtube)cheap eBENK LANC remote for zoom as he does, i would make my own LANC with arduino... you keep more control when you can play with code...

Also i am not a fan of wireless devices, often i works in very crowded places and some theaters are very strict on wireless devices usage to not interfere with their wireless microphones....
Who's gonna be blamed first if any interference problems?
Who will be forced to shut down his system?

Anyway i use SDI cables to cameras... if you can run a wire instead of wireless... go wired!

it's my humble opinion... still a very nice overall setup! just not for me....

Same for me, I try to keep out of wireless as much as possible...

@Spino, you can check for "camranger" for wireless controlling Bescor heads. Don't know if based on Arduinos, but it already exists...
