Hi Andrew!

". . you could probably benefit from using a counter balance weight with that long heavy lens to get the centre of mass near to the pivot point."

Yes - i´m doing that already, but it´s a heavy load to the whole construction i´m afraid . .
My concern is the manual moving - horizontal i can move the tripod´s colum or the leveler.
But to set the camera to vertical "0" it´s got to be moved manually very often - it´s slower doing it by
using the motors.

once you open up the Merlin you will not move it any longer manually
it's a rockblasting cheap construction :-)

not designed for any additional tear and wear ...

on the other hand it's cheaper to replace a complete Merlin than a gearbox in a more solid device ...

Right. Once - in a shining future being a world-known famous panographer - i will buy a more sturdy device . . . :P:cool:
Until then i have no problem to accept the Merlin´s (few) shortcomes ;).

P.S.: maybe it´s worth some tuning efforts . .

Hi Klaus,
Nikon 2,8/300=2.870g
D3= 1.240g
Together about 4K
The Merlin can have 5K
If you use an extended camera rail you can add some weight at front when you use the camera shifted backwards.
Mount the Merlin directly on the tripod and level it with the legs.
A heavy Gitzo with centre column will do.
Maybe you can show us a set-up picture with the 300mm:)

BTW:Maybe these "OT Posts" should be moved to the crown-modification part .
The TS subject is BT :)

two versions of bluetooth modules are offerd by TA:
the BLTm and the BLTc with included Canon "EOS Expositionssteuerung".

my questions:
in combination with Merlin+CanonEOSD400+PW:

what does the "EOS Expositionssteuerung" in combination with merlin?
or simply I only need the BLTm?
do both versions work with the PW 2.x branch?

many thanks in advance!
Liebe Gruesse,
Georg

Hello,

I am the developer of these Bluetooth modules.

The BLTm is the original one. This version is used by some members of this forum.
The BLTc is a totally new development: (It is finished right now)

Image

It has an output for the camera control. It interprets the ":O1n" command and doesn't route it to the Merlin.
Connect your camera to the Bluetooth module, not to the Merlin.
The BLTc has extra features: It implements all of the two contacts to the camera: shoot and focusing.
Both of these contacts are opto isolated.
There is an extra command: ":X1n" whre n can be 0,1,2 or 3.
bit 0 means shooting, bit 1 means focusing.
0: shoot off, focus off
1: shoot on, focus off
2: shoot off, focus on
3: shoot on, focus on

Other new feature is under programming now: Shooting with internal millisecond resolution timer.
This will be read in few days.

Hi Tamas,

Nice !
Will it be OK for the Merlin "Go-To" version ?
Any idea of the cost ?

Hi Claude,

Yes, it will be ok with the goto version of Merlin. It was the main goal of the development.
It also will be useful with SupaTrak mount which is heavier than Merlin (Maybe useful for bigger telephoto lenses)
It is a bigger brother of MF-1.
Unfortunatelly not aligned to NPP position, but it can be corrected with a little do-it-yourself.

Price calculation of the new Bluetooth module is not finished yet, but will be aprox. 30% higher than original.

The original Bluetooth interface remains in production and its price won't be modified. Customers can choose between the two version.

So I will have to write a special Papywizard plugin for the new features of this module ;) Mainly, I think I will add a focus flag, to allow the user to focus before shooting, and another pulse length value.

You should get one for free :-)

Hello,

I've finished the development of the new Bluetooth interface.
I've also written a small program to test its new functions. This is a freeware program and can be downloaded from my homepage:

http://www.ursaminor.hu/downloads_en.html

Just download the "merlin_test.zip", unpack it (contains only a single exe file) and run it. No need of java, .NET, Python, Ascom etc...

Image

As you can see on the right side you can choose between the three way of camera remote control modes.
- At the first case, the program sends the ":O1x" command. Merlin interprets it, or if you use the new Bluetooth interface, it will process it.
- The second case is using the RTS signal of RS232. (For USB-serial converters, like our USB combined cable.)
- In the third case the program sends the new commands for the new Bluetooth module: ":X1n", where n specifies the state of both focus and shutter contacts.
As you can see, the internally timed shooting also possible. The Bluetoot interface's microcontroller does the millisecond resolution timing.

Best regards,
Tamas

Hello Tamas,

I was wondering how to name the plugins for your interfaces. What about:

Ursa-Minor-BT-v1
Ursa-Minor-USB-RTS
Ursa-Minor-BT-v2

What other guys think about it?

Hi Tamas,

how does your Merlin Test prog connect to a specific Ursaminor-BT?
I see only a config via com-port, so do you use the device-name of the bt-unit to find out the mac-adress?
Doesn't it confuse the Merlins, if more than one is reachable (as it may be on a pano-meeting)?

Hi Paul,

It doesn't confuse when more Merlins are reachable.
Just consider, you have to pair the devece to the computer before use it.
You can do the pairing at home when no other Merlins are reachable. During the pairing method, a com port number will be assigned to this Bluetooth Module (assigned to its mac address).
This pairing method should be done only once. Later, on the pano-meeting you shouldn't do pairing again, because the computer and the Bluetooth dewice knows each other.
They wont collide with other similar devices.

Hi Frederic,

In the first case, the Ursa Minor Bt1 doesn't require a dedicated plugin, because it is totally transparent. The operation is exactly similar as wired connection through serial port.

The second case: "Ursa Minor combined USB cable" may be more suitable name. The name should'n contain the name of RTS signal. Later I'd like to improve this interface to add the second contact to auto focusing, maybe on the dtr line. The perfect way is let the user choose between all of the rs232 signals and signal polarity. It can make the plugin more universal.

Third case: "Ursa Minor Bluetooth Interface V2" is a good name. This is a dedicated plugin to the dedicated interface implementing its special commands.

Ok, but the names are too long for the GUI...

About the serial line, the plugin trigger both RTS and DTR lines. If you split for AF and trigger, I will add params...

How about Ursa Minor BT1, Ursa Minor USB and Ursa Minor BT2?

Or UM BT1, UM USB and UM BT2?

sorry,
but thats very intransparent for a "normal" user, as Windows doesn't tell anything about the COM-Port and even with systemsettings one are not able to find out to which COM a BT-Device is connected

it is a jump and run adventure to figure it out via the device manager, the more BT-devices one has connected to his pc, the more try-and-error steps one need

Hi Paul,

No need to use the device manager. The com port number can be more easily find out from Bluetooth settings menu.
You can read how it works on my homepage:

http://www.ursaminor.hu/bluetooth_interface_en.html

See the "Checking the COM port assignment" topic on that page.
