(look at the 4.4" sized display (same resolution as our latest lcd)

quote from the nikonhacker forum, regarding leedong, one of the great nikon hacker guys (brought raw video to the nikon d800, but never finished it...), reverseengeneering the nikon lens protocol

Currently the idea is to reverse engineer the lens controls on the e mount on the Beta. There are a lot of adapters out there that not only provide a physical conversion to Nikon, Canon, etc. but also do lens control translation.

Hi everybody, I write my question in the remote page but i think, it is better to write here :

agree, but just to have the soldering option for handheld use if it is easy and cost free to make..?

Here I have to add that this could have very negative side effects if the remote is attached to the camera and the entire camera is subject to vibration during shooting.

would it be possible to add soldering for some kind of mechanical feedback (vibrating device, small hammers) which are munted to the enclosure?

i got the data sheets for the mentioned lcd

For any LCD/LED/eInk display that we want to consider, please first make sure that a datasheet is available and link it here, so that we can do some basic technical plausibility checks ...

I am also concerned about sunlight readability of the current LCD but we are building a first prototype not ordering 1000 units already so I think for the prototype its perfectly fine to just see and test it then, if we see that its completely unreadable in sunlight then its the perfect moment to reconsider the LCD and still keep the rest of the components the same.

I know it's pretty late for such an input, but i wonder if we have decided right.
Shouldnt we opt for an transreflective LCD? Something like that one
I searched arround a while for sunlight readable displays and the best which comes up are transreflective-monochrome ones. Just now i held my audio recorder with it's monochrome LCD in my Hand and i am impressed by it's readability.
We made the decision already therefore i totally understand if we stick to it!

so the battery is shown as full even if it's empty? :D

eink might not be too slow if only (small) part of the screen is refreshed. And it would be damn cool to have all the settings shown even is the camera is not powered :-)

I already ruled out e-ink already because of the slow refresh rate of the display.

if we want to go for an eInk/ePaper dispay, we need to get a sample for testing.

either lemo connectors that fell off a truck or chinese lemo clones.

interesting finds!

what about this display, e-ink, Active Area 66.0 x 88.0mm (4.3 inch), refresh time 260ms, 230dpi
or different size, Active Area 45.7x76.16mm

I ordered a wide selection of switches with different operation force from 0.6N to 24N that we should also soon be able to test.

does anyone know which switches are used for the aaton cantar-X2 ? especially the small ones
how does these small buttons feel? how much pressure do they need?

interesting switches

these could be fine batteries.. do anyone know more about that technology?

A small screen (3-4") should be around 30$. i don't know how "budget" it is for that project, but it really would help save energy. maybe you can also get cheaper ones somewhere (had a look on alibaba). there is even color e-ink on the market. everything except audio levels could be well displayed. another advantage, for assistant or others, would be a stable picture on any view angle.

Ah, sorry, for the remote less power is required of course.

If you find a panel that does 6-41V with roughly 3-5A then it should be fine.

eInk is very interesting. is it possible to change just the pixels that changed?

Okay, cool - although bear in mind I'm a cameraman not a sound recordist - they may have different opinions. Having said that one of great advantages of the Axiom is that it's open source - if people hate the noisy buttons they can go and make some silent ones...

thanks for the feedback, we will head for the long lasting clicky ones that feel good then :)

I'm impressed you're thinking about the noise of the buttons- I doubt a angle camera manifacturer has ever thought about that!

@bergspetzl
Did you find any available parts that you would recommend for e-ink displays? I would be quite interested to evaluate this.

what about an ink-display? at least power consumption would be very low an it would be readable even in brightest sunlight. on the other side it is not so reactive like an lcd or simulare display type.

Ah that reminds me, another important parameter for the selected LCD is that its readable in direct sunlight.

my preference are:

what about this one?
http://www.amazon.de/SainSmart-3-2-TFT-LCD-Display/dp/B008HWL8QS

all settled for now.

My preferences are:

• 2.5" - 4" screen diagonal
• 150+ DPI
