DIY power supply for digital back h5D-50wifi

[90s]

Hello, I'm new, but I have been using hasselblad for 3 years.
Some time ago I built my own wall for a 5x7 large format camera. It moves in two axes.
Unfortunately, I have to use a computer to power my back. Which is uncomfortable in my situation.
The original adapter is not worth the price.Battery Adapter (3053310)+ plate 3053312
I would like to make my own layout because in the photo it looks like a simple plug.
The power supply battery is: 7.2V "Sony™ NP-F L-type" battery

My question is this, has anyone done something like this?
what plug is needed there
and what to use as a power source.?

Thank you

I used this one for H5D60-Back:

Outer Diameter 3,5 / Inner 1,3 mm
Can use any Source, that gives 7.2 Volt DC.

Thank you DBF for a quick response.
This is how I would like to build it.

Do you have a better solution?

Thank you

[DBF]

Good - go ahead.
When ready send a Picture of it to HB and laugh for at least three Seconds....

[90s]

Hahah OK;)
This is the biggest joke.

"HB" stands for High Price - Bad Service.
Did they ever get a Camera ready with alle Features before the next came out?? R.I.P.

[90s]

This is true.
I have H5D WIFI and can't connect to PC and Phocus.
Just some weird cable or tablet ,smartphone.
The H system is losing value faster than cars.
I love my camera and I would like the H6D-100 but I don't know if it's worth buying anything else in this system.

[DBF]

I have tried the 100 - never ever will I buy it.
The Digital HB`s can make fine Pictures, but mine were / are not reliable.

[90s]

What did you not like?
On paper H6D-100c looks perfect to me.

[DBF]

The Colours!!
The Sensor is also in a Phase1 Back - little bit better, but no good for me.
The newer 150 MP Sensor is even worse.
For me, the 60 MP CCD Sensor is "End of Line"

[Conner999]

I have for sale a modified Hassy AC kit I added the ability to use L batteries with, plus some extra cords & plugs. Works like a charm - just plug into back or grip.

http://www.hasselbladdigitalforum.com/index.php?topic=6725.0

Do bear in mind, there IS circuitry inside the DC adapter grip (it's not just an empty shell), possibly to regulate power between the camera & back. I don't know if the grossly over-priced back adapter has any 'guts' or is just empty plastic.  The RC battery you show is no larger in capacity than the ones inside the 3200mAh grip.

Whereas 6600maH or larger L batteries are cheap as chips (I bought 2 batteries and 2 chargers for like US$50), last bloody forever and can be used in LED lights, etc.

The Hassy grip itself can be used with any ~7.5V DC power source that can deliver at least 6A (hence the 6600mAh batteries I use).

Good luck.

CCD has unique colors but such a difference with the new CMOS?

Thank you for your answer.
Can I see what this system looks like? I'm worried about overload protection.
Does this original battery adapter have any protection system. I don't want to fry the sensor.

[Conner999]

This is the factory unit that I essentially adapted with different plugs to run as is (AC to Hassy grip) or via L batteries (L battery to Hassy grip). the Hassy grip that comes with the unit does have some form of regulating circuitry inside.

Thank you

I'm looking power for back without a body.

[Conner999]

I realize - but may be adaptable to powering just the back as it is the nominal 7.4V source with ample amperage as needed (see below however).

The question is if the costly Hassy L battery adapter (for just the back), like the AC adapter grip have power-grooming/protection circuitry inside or is it empty or just an Eprom, etc., to check battery status?

EDIT: Just as an FYI. I got curious - when measured at the various output points, the DC voltages read as follows:

Terminals of a 3200 mAh battery: ~8.15V
Terminals of the Hassy AC adapter (before grip): 8.67v (though says output is 7.5V)
Terminals of two different manufactures & size L batteries: 9.15V
Terminal of the DC Power Grip (hooked to L batteries) where hooks to camera: 9.15V

So, it appears any voltage regulation takes place inside the camera body itself.  This somewhat makes sense as the camera can be powered by a variety of means. The grip(s) may contain over-voltage protection (to save costly internal repairs). Interesting.

Good luck w/project.
