"Some smaller aspheric lenses I tried at home would work but I am not satisfied with screen size or eye relief after mod. This will need several lenses combination system in order to work not just single aspheric... "

What ? Are we the HUBBLE telescope?
Lens B to correct lens A.


Why not just do the right lens A from the get go? :crazy:

Not, the reason for this post........


For others...
The driver board the wiring, I had forgotten.
I did test that, use either black wire...cap or cut off the other.

Look at the original post, page 1 #1.
The pic of the unit.
2 wires one a vid out , another the power supply.

They just have 2 tap outs, of grnd on the driver board.
1 for power supply
1 for vid

Mr. Newbie,

I am not quite sure I got you but yes... You will not be able to find single aspheric lenses that will enlarge image enough to be usable or to have decent eye relief... Single lens will enlarge it to certain point but that will not be enough I am afraid.

You know when we put our 50mm lenses to VF-2C display? That mod extended eye relief significantly but it also lost around 15% on image size.
Our 50mm lens is 5 x lens system (combination of aspheric, concave and convex lenses).

So yes we will need to be HUBBLE telscope to resolve this issue. :thumbup:

Happy New Year!

Well, I thought you were nuts :lol: :lol: :lol:

But, Its not my area of knowledge and there is nothing more I can do with it.
Mine was taken apart so many times, I started to have cable problems.
Put it back together and put some epoxy on everything to lock it all down before I trashed it.

Hey, if it takes a couple lenses then it does. Hope you or someone gets it all working.


Happy New Year to All !!

To save confusion in the future, ive called the new display VFV3

This is the wiring colors as they differ from the norm

Red:VCC to your video signal
Black:GND
White:CVBS Positive up to 5v max
Gold:CVBS Negative


Hope this helps

When I crack this one I'll order another one from your store :thumbup:
I think this is great addition to your store and especially for EU costumers because we don't have to pay any additional customs tax.

Edit:

"Red:VCC to your video signal
Black:GND
White:CVBS Positive up to 5v max
Gold:CVBS Negative"

Splatty this does not help at all I am afraid. VCC means power on my all cameras... So "vcc to your video signal" is strange expression to my crazy head.

"CVBS positive to 5V max?" So cvbs is video wire so it is very confusing to see video wire up to 5V max?

Did I got it right? Please check it cause I am not really sure from your post so it would be good if you could check and confirm.
Red is power wire (this unit is from 3.7 to 5V max or poof will happen)
Black is power supply ground
White is just video wire?
Gold is probably exposed copper braid as video negative wire?

Sorry for bothering you but I think we need to 100% clear this for future diy generations :)

Wiring:

Red: power 3.5 - 5v DC +
