BM Micro Studio Camera with Pan/Tilt & SDI

PostThu May 10, 2018 12:29 pm

Thank you Blackmagic! With the latest ATEM software update it is now possible to carry PTZ support over SDI in combination with an ATEM panel. Which is great, so I started modifying DMX moving heads with electronics and mounted a BlackMagic Micro Studio Camera inside. The camera is mounted in a light but strong surface from 3D printed carbon/fiber material. Signals and power connected with a FieldCast Hybrid fiber cable.

Wow, this looks great. ¿Can you already move the DMX with the ATEM pannel?

Yes the units are fully working with smooth 16bit movement.

Nice concept, but I hope you left enough air vents for the camera.

Yes indeed. It has an extra fan on the back side to keep the camera cool.

I’me just doing quite the same for some month. This is a good second life for a Mac101

How did you manage the pan tilt translation? I’m for now stuck on that part of the job? To me even if the panel sends ptz commands, that is not enough because there are no position memory’s at all.

At the moment I left the PanTilt job to a dmx software but that’s not to so easy to use because the zoom/focus commands are on the atem software...

@ Greg: If I have some time tomorrow, I'll shoot a short video how the setup works.
@ Mikaël: I developed a PCB that is translating protocols. I'm storing the memories in an I2C EEPROM on the PCB.

@mikeal, With stepper motors that would work also.. But you have to build your own hardware software.. ;)

Your PT head is going to NULL at startup.. It will rotate to the end position and from there the microprocessor keeps track of every step your motors make.
So preset 1 is X 1290 steps Y = 412 steps. Store.
Preset 2 is X 573 steps Y = 789 steps Store.. Etc.. And then when recalling the presets It will compare it's memory preset with the current location and will start turning to that position.. ;)

** I'm already talking to much in Programmer logic haha..

That is what Marc does inside his hardware.. So skip the whole DMX.. And just take the Visca commands from the camera and translate that into Steps for the motors.. Google a bit in Steppermotor arduino and you will find more info on how you could make something like that.. ;)

Yeah, I also thought about visca commands but I haven't found any topic or library about Visca reading... Maybe my google skills aren't so good too. :D

with the all new optical fiber converter and the BMD arduino shield that would be a good start.

But, I still can't understand haw to recall memories through the advanced panel. or do you use an external PTZ controller?

Atem and panel needs to run the latest firmware. Go to the smart menu and go to PTZ. There should be a few options there.. ;)

I dont own the advanced panel but i have the older one.. That has the option under 1 of the lcd buttons..

Here is the visca protocol. But you need some coding skills to make it work.. It doesn't come in chuck byte sized packages.. Yes it does.. But then we are talking about commercial products.. :lol:

If you would take up such a project, and have not a lot of electral / coding skills.. Be prepared to spend 6 months of learning, trying, coding, testing, recode, testing, pulling your hear out, recoding and repeat.. :D

Yes both run the latest fw. I can move the camera through visca but nothing about memories...Image

Okee.. Then the BMD FW functions dever from device to device.. It is already inside the protocol.. But for some reason they did not write it in the advanced panel... :?

I prepared the firmware for the memory commands, but I also don't see presets in the SDI menu for the moment on my ME/1 panel.
