Before I saw the STL files, I got cracking on my own version since I had a spare Sony A6400 cage lying around. I made a few modifications. After some 6 or 7 prototypes, this is the first version that's any good, lol. It doesn't hold a candle to Csaba Navy's beautiful and more compact version but this is my first design for a device. The Raspberry Pi is already enclosed in an aluminium case so I bored a few holes and designed around it. The case acts as a massive heatsink. I did manage to keep the temps below 50°C. Haven't been able to display on my Atomos Ninja for some reason and I don't have a usable SSD. It works fine displaying on my monitor and I am shocked at how beautiful it looks, even without processing. Great job on the software side!

EDIT: There is an Arca Swiss bracket behind. I 3D printed mounting plates and simply stuck them to whatever accessory I want to mount behind. In this case it is a Sony Power Bank capable of powering the whole system. I'd like to thank everyone for the inspiration to build this. Can't wait to go out and shoot stuff!

Great job on your design! looks very functional with all the accessories and attachments very well thought out! :)

Hope you will share your footage soon.

Thank you so much schoolpost, you're very kind. It means much coming from you!

I could not get it to work on one of my SSDs with a reader. I have to get a Samsung t5 or equivalent, soon. Can't wait to shoot.

Three questions:
1. While I am quite handy with mechanical things, i am a dilettante with software. I cannot get a feed on my Ninja V and i did see something about changing the output resolution. I don't know which line this corresponds to in the config file, could you help me out?
2. While using My Camera Controller, i cannot find my Raspberry Pi as names are seldom displayed. Just a lot of Unknown Devices.
3. How do I access the terminal/command line of the camera with a mouse/keyboard plugged in? I think that I can setup the WIFI from there.

If you are on a Mac, you can connect the CinePi via an ethernet cable. Make sure "Internet sharing" is on (System Preferences > Sharing). Open terminal and type

Code: Select all

ssh pi@192.168.2.2
Sometimes I find my CinePi at 192.168.2.3. Password is cinemapi.

I find this the most convenient way to get access to the CinePi. Also noticed that CPU temperature was raised considerably with wifi being turned on, so I guess it is better to leave it off.

You can read more here about changing HDMI modes here:
https://www.raspberrypi.org/documentati ... g_txt.html

The mode is currently set to 84 which is the 2048x1152 resolution which may be a resolution unsupported by the monitor. Either change the mode to some other resolution or comment out that line. This is done by editing the config.txt file on the micro-sd card.

Yup! Thanks again schoolpost. I used Mode 72 and it worked like a charm. I just need the SSD and I'm good to go!

BTW, How do you configure the Bluetooth and/or select it on an external Camera control app? All I see are arbitrary letters and numbers. Besides the SSD, this is the part I am missing at the moment.

Widely reported that Bluetooth functionality isn't working with this build with various different camera control apps. I'm still in the process of looking into this. I may already have fixed this on the version I've been using that is slightly different from the alpha release. I just need to image/compress my Raspbian for release which is a slightly tedious process.

Unfortunately with the current state of the project, any changes to the code base ( no matter how small ) requires the release of an entire disk image. Ideally the project and it's components would be a standalone repository that would be installed onto Raspbian, but given the modifications that need to be made to the kernel and some other low level configuration it makes it this kind of difficult ( not impossible, simply a task I've never done yet. )

Finally got around to it. Here is a new release for CinePi-2K: https://github.com/schoolpost/CinePI/re ... .0.1-alpha

The changes are listed on the GitHub releases page. But mainly, this release should resolve the Bluetooth control compatibility issue people were having.

Reminder for anyone who modified their version of CinePi-2K, to save/move/copy any new changes somewhere else as a backup before they flash this version of the release onto the same micro-sd card. Or use a different micro-sd card for this release.

I have downloaded the Release 1.0.1 version, but after flashing my sd card with the new version, it still shows as Cinepi V1.0.0 after booting up. Bluetooth connection is still not working. Or maybe I might have done something wrong?

I also took the chance to build a CinePI System.

I´ve printed the modell from Github and I´m very satisfied with the system so far :) .

The Bluetooth+ App for Blackmagic for iOS works so far flawlessly!

I´ve used a RPi4 with 4GB of ram, but my takes never go over 40sec., so I can´t say anything about how far I will be able to go. But I will test this in the next few week.

I´ve tool a video from printing some parts for the case, nothing special, just testing the system. The lens was an old Fujinon Zoom lens (12.5-75mm). Because we have a really bad day today I´ve had to take the shot with ISO 800. Sorry for all the grain.

Great stuff! Please share when you complete the building process and if you need any help with assembeling the case ( I haven't had time to finish the documentation for the physical case assembly ) just ask here.

Thanks a lot!

Today I´ve got the chance to take some material outside in the garden. I´ll post this later on.

I´ve one question at the moment. When doing some filming, the whole folder were the material was saved show the date of 01.10.2021 at different time. Is there a chance to get the correct date of the material?

Also you mentioned the experimental audio recording. Have you done some test with this? At the moment this isn´t really important at all for me, but it could be in the future.

In the long term I have to buy a field monitor because thee 5" HDMI display won´t give me informations about focus peaking etc. I´ve used it only for my testing setup at the moment.

But at the moment I´m really satisfied with this setup!

I´m looing foward for the further progress CinePI will do!

Update

Here is the second footage.
