PWM(S.Bus)+LANC+DC BMMCC Angle Expansion Box Module

PostFri Feb 10, 2017 4:26 am

Hi there! As you may know i'm a developer of Angle HDMI Clamp Kit https://forum.blackmagicdesign.com/viewtopic.php?f=14&t=55124 and co-designer of SmallRig BMMCC cage. My next attempt in this line of projects was the camera handle, but it seems things moving slowly and i decide to release Angle Expansion Box Module first.
Box uses high quality connectors made by Lumberg (Germany). It takes months to test a lot of different connectors before choose proper ones, especially DC power which should work smoothly with BMMCC power plug same as with another more simple ones. Angle shape provides compact and secure cable management, no more mess of wires around camera. Fits perfectly to size and shape of BMMCC Angle HDMI Clamp Kit. 3D printed body. Compatible with SmallRig cage. Compatible with other BMMCC controllers.
3.5mm jack can be mapped to 2 PWM channels or to S.Bus. Other connectors are 2.5 jack LANC and camera DC power in.

For more details send me a private message or contact directly to radioproektor (@) gmail . com

Currently i search a better way to manufacture a box body. At this Sunday my friends made test samples on usual FDM 3D printer and i don't like the results. It appears not too precise and material not strong enough for this kind of small things, also it takes too many time for batch manufacture. So i refuse my idea of simple 3D printed body.
Now i got few other more precise and professional manufacture options, like DLP/SLA 3D printers or CNC machined body sample for future molding. Need to test that things too...

Also i find a solution for more flexible pinout. Everything will be connected directly to D-sub pins with tiny Dupont Jumpers. Anytime you can just open the box and change pinout for example from S.bus to PWM or to anything you want.

This is final design of the cap. It inserts deeper as earlier versions into box body and improves rigidity, same time saves a lot of space and allow to use smaller length screws now.

Also want to share a little chart after testing Lumberg/EST vs OEM China connectors comparison. DC power connectors are also different. I can't find a Lumberg DC power connectors in local stores yet, but already find another brand which is better quality than OEM.

Hey Dmitry,

This is interesting! It looks tidy!

So when you say $25-$50 is that for the completed device or for the kit which would require assembly?

Sure it will be assembled and ready to use product. Currently i search the better way to print a high quality model with precision 0.05mm, and convert it to silicone shape for molding. Next, this box will be manufactured time to time in small batches (5-10pcs) from rugged material and assembled.

Oh cool!

So you have a lanc the power and then a 3.5mm jack as well? What would you plug into that? Another lanc like device?

I think the 3.5mm jack is connected to the SBus for a SBus based remote, or can be connected to a PWM pin connection to get ISO or WB remote toggle control.

I plane to develop in future a grip with simple rec/stop PWM button to this box. 3.5mm jack is freely configurable you can map it to two PWM buttons and just connect a simple button to it. Or map to more complicated S.Bus protocol and use with any S.Bus controller developed last times for this camera.

As i wrote earlier:
Also i find a solution for more flexible pinout. Everything will be connected directly to D-sub pins with tiny Dupont Jumpers. Anytime you can just open the box and change pinout for example from S.bus to PWM or to anything you want.

In the final final version i decided to add extra elements around d-sub connector for better support and stability. Still searching for best 3D printer possible for master copy. Stratasys Objet30 printers looks great but very expensive, DLP printers are another option but needs more post processing handwork to finish. Also some sketches for future molding setup. It appears that manufacture of decent silicone shape will be the most complicated thing in this adventure.

OK people, some news here:
After long research i dropped the concept of DIY silicone molding and plastic casting because it appears too complicated, requires a lot of additional gear, results are not always predictable, and experiments may take many months. Also i find that those plastic casting materials are not too heat resistant and can deform under extreme sun. It is also problematic to get a neutral deep black color with them.
So i return to concept of 3D printed box. I tested few different FDM 3D printers and find that they can produce very different results depending of used material and printer brand. Also instead of unpredictable fragile ABS plastic i find Elastan D70 - new industrial material developed by local manufacturer. It is solid but same time slightly elastic and resistant to impact loads (95 Shore Type D). Usable in temps from -40 to +120 °С. Resistant to UV light, X-ray, wet, oils, fats and many solvents, safe for food contact, low shrinkage durable material.
Internal part of the box was also redesigned. It became much stronger now.
In day or so i'll get a first test sample of printed box so we can see how it looks, how it feels and do a crash test with heavy hammer.

Printed on FlashForge Creator Pro FDM 3D printer with layer thickness 0.1mm with black PET plastic (aka coPET).
Sanded, painted with textured spray and black paint layer (RAL9005). Now i'm really happy with result and ready for batch manufacture.

All cables connected to D-SUB pins with tiny jumper plugs, so you can open the box and change configuration as you like just in few seconds.

And first boxes will be shipped in few days.

Also if someone needs slim angle cables check these links:
http://www.ebay.com/itm/142179109943?_trksid=p2055119.m1438.l2649&var=441245745900&ssPageName=STRK%3AMEBIDX%3AIT

It seems this is the only one seller who sells them. They are thinner than normal cables, very slim and flex. You can see same cables connected to expansion box compared to normal sized ones in earlier posts here.

PWM(S.Bus)+LANC+12V DC Angle Breakout Expansion Box Module developed by RADIOPROEKTOR for Blackmagic Micro Cinema Camera (BMMCC) and Blackmagic Micro Studio Camera 4K (BMMSC).
Angle shape provides compact and secure cable management without mess of wires around the camera. Box compatible with SmallRig cage and can be used without any cage as well. Perfectly fits to size and shape of BMMCC Angle HDMI Clamp Kit.
Box uses high quality TRS connectors made by Lumberg/EST (Germany/Japan). Everything is connected with tiny Dupont Jumpers, so you can open the box and easily change cables configuration for your needs just in few seconds. This makes it compatible with any PWM and S.Bus camera controllers, allow for Composite video signal output, Genlock/Reference input or any other desired option.

P.S. I don't want to overprice things but it appears that BMMCC market is really small and there is no huge profits for selling hand made stuff like this in small batches. So if you on high budget production and if you wish to support future development feel free to add additional $5-10 as donation. Just notice me about this before purchase.

Installation tip:
1. Insert Expansion Box into the camera.
2. Tight UPPER screw.
3. Slightly tight LOWER screw. (If you tight lower screw first, this can cause Expansion Box inserted unevenly because camera side has slightly curved shape)

Tech Specs:
1 x 3.5mm TRS jack socket for PWM, S.Bus or any other user selectable inputs/outputs.
1 x 2.5mm TRS jack socket for LANC input.
1 x 5.5x2.1mm (5.5x2.5mm compatible) 12V DC power input socket.
1 x DB-HD15 serial connector.
The housing is 3Dprinted from coPET material, sanded and finished with acrylic paint.
Dimensions: 34x34x29mm
Weight: 28g
Operating Temperature: -20°C to +70°C


Package includes
- Angle Breakout Expansion Box
- 2pcs #4-40UNC screws (Stainless Steel or Black Oxide Steel for your choice)
- 3/32 allen wrench hex key


Package cost total:
Angle Breakout Expansion Box = $50 + optional donation
Worldwide shipping by registered air mail with tracking number = $6
Payoneer funds transfer fee = 3%


Currently I can accept payments only with Payoneer Billing Service because PayPal don't works in my country for receiving funds.
Here are few links explains how the Payoneer Request a Payment service works:

:arrow: Currently all boxes sold out!
But i have planes to release version 2 of Angle Expansion Box Module with CNC machined aluminum enclosure! 3D printed enclosures work very well but too slow in manufacture and needs too many dumb hand work to make them look nice. The external dimensions and overall look will be exact same as in Expansion Box v.1. Changes and modifications will be only under the hood. Probably new enclosure will be slightly heaver. Also based on users feedback i move body to 0.6mm backward to make it more easy to fit to Wooden Camera cage.
Hope that next batch will be available in autumn.

Some things done during last months:

- It seems CNC Aluminum enclosure will not happen. Huge delays due summer-autumn typhoons disasters in Asia factories. Also CNC manufacture prices for this part appears way higher than i expected.
- After watching one more tutorial
i decide move to silicone mold rubber and liquid urethane plastic casting. Again.
After bad experience with DLP 3D printer in spring (too shrinked dimensions due wrong model orientation and printer tuning) i decide go for Stratasys Objet 30 dental prime 3D printer. And it was another disappointment. All surface was covered with thin rubber-like layer of un washed support material. Also finish quality appears way lower than it was from DLP printer. Stratasys Objet 30 PolyJet 3D print (XY 45 micron with 16 micron layer) looks worse and less clean than DLP 3D print (XY 50 micron with 25 microns layer). It is also overpriced compare DLP and needs even more hand work post processing than removing support pins from DLP printers.
But after 2 days of hand work master model became clear and very smooth.
- Currently i finish the design and almost get all necessary components to build complicated and precise support for futureproof silicone mold.
- I found small factory team who can do silicone casting with vacuum degassing and do liquid urethane plastic casting in high pressure camera. This helps to get rid of the bubbles when casting, but kind of technology that not so easy to setup at home.
- 3D model was redrawn in CAD programs and overall geometry became better and cleaner.
- Rear side of the Expansion Box is now reinforced with stainless steel washers inside.
- All electronic components assembled and ready long time ago.
- More additional custom made tools where created to speed up manufacture.
- For safer shipping i got small hard cardboard package boxes now.

Dmitry, you should make breakout box that will interface with Phil’s new One Little Goat Lite controller, using a TRRS (4-conductor) plug tp connect SBus and Lanc from the camera to the new OLG Lite controller, with power and Lanc ports, so it will fit with the Wooden Camera Micro cage, like your breakout box does.

I would be in for one, even at $25-40, so I can use the new remote with my Micro Cinema Camera and BM Hand Grip on the WC Micro Cage. Lots of WC. I do cages were sold, so I can not be the on,ymine here needing/wanting one. Phil seems locked into his larger breakout box, while nice, just does not fit with the WC cage, as he designed it to fit the Smallrig cage.

Yes, while this works, you loose the led Talley light on the remote, as it gets this from the Lanc signal, which is the fourth connection one the TRRS connection. Would be nice to keep the record Talley light working. But I will give this a go.

Here is my statement:
- This Expansion box designed as flexible and free adjustable device. It is not made for any specific single controller in mind. Everything is connected with tiny Dupont Jumpers, so you can open the box and easily change cables configuration
- All pinout specs and connection charts are available in this thread.
- It provides separate S.Bus (or PWM or Genlock or Analogue video out), LANC and DC power connection.
- It is made to fit to SmallRig BMMCC 1773 cage and to dimensions of my other accessories eco system. It fits to WoodenCamera cage very tight or may not fit at all.
- I don't have TRRS sockets and don't know where to find them.
- It is impossible preserve free adjustable concept if use TRRS sockets.
- I don't know what pinout connection used in S.Bus controllers manufactured by other people.
- I think it is just bad idea to mix two different interfaces (S.Bus and LANC) in one cable.
