$10000?!
jesus, you could hire a chopper to floodlight the shooting area for that!

I had a look through a front mounter. TBH I never thought it looked pixelated!
CCD might be a better option if it proved to be a issue. Edd, a good point about the wide angle at the back of the unit. Adding some distance between the lens of the scope and the NV might help as well.

my lens and adaptor just turned up......
very small, small enough I am thinking for normal eye relief!
Project: "Whothefeckareyukon" continues
build and test to be done after munchkin lights out!

well that didnt work!
lens packaging with the CS mount adaptor is spot on.
lens however leaves me with a view of the internal tube of the scope rather than the sight picture
poor choice of focal length and FOV
back to the catalogue

Keep up the good work, are you going to publish a parts list when you're done ? I keep looking at my Bresser unit now I've seen this thread

yep.
have a top chap at an optics company helping me out so will direct people there
rest of the stuff is from Maplin

Lardyvision does look good but I don't see any internal details or help in building your own or any for sale.
To me that doesnt make sense.
Either build it and sell it or build it and let others make their own
finally go the replacement lens:
true x1 magnification, in focus and I can see the reticule and sight picture clearly.
need to re-house it as the boxes I have are now cut for larger longer lenses
With this lens I am even more confident I can mount this behind the scope keeping normal sight picture, eye relief and cheek weld

I am playing the same game and a 16mm CCTV lens appears to be the way to go.

Bewsher,
i'm following this thread with great interest, just wondering what sort of range you think will be possible when finished, weather it would survive the recoil from a centerfire
keep up the good work
cheers jock

The missus picked me up a Bresser NV today at some fair in Haddington, £50. So far so good, it works, so I`ll get out for a play with it shortly

mine is a 16mm lens as well but it needs to be mounted too far from the obj lens to give decent eye relief so I am going to trial a different lens
I plan on mounting it on my .222 but to be honest I can only see this being MORE resilient to recoil than the optical NV gear
it weighs next to nothing, it only has chips and boards which are nothing like as sensitive as an NV tube.
I imagine I will lose some range but on well lit (either laser or moon) nights you can see easily further than you can shoot
I am hoping for a good 200yds through the scope though

update
swapped the 16mm board lens for a 12mm board lens and got much better eye relief and FOV
ordered an 8mm lens but was sent a 6mm instead. am hoping the 8mm is on the money for sight picture and FOV.
with a 12mm lens you get 77mm of space between Occular scope lens and objective NV lens, want to get that down to 40-50mm hopefully
tried to take a picture of the reticule view which is clear and a perfect facsimile of the sight picture through the scope.
The onboard IR is a tight beam about 4m across at 50yds
Bought a fatter housing that will take the battery unit as well
looks like this until tomorrow!
(double AA power pack takes up most of the box to the left of the IR)

I've been following this thread with interest - great work. Thinking about the power supply, have you had a look at Li-Po batteries? They are very common for Radio Control planes and used in phone batteries, rechargable, light and very high capacity. A single cell is 3.7v and can be linked in parallel to give any capacity you want.

I have looked at them but they are pricey.
the best I could do was a £10 unit from RS or Maplin.
TBH for the power these things use a couple of rechargeable 1200mAh AA's in a housing is all I need.
the biggest issue for me is the variable switch and the AV out connector as they are bulky and I could do with making them remote rather than board mounted.
If I can do that I lose at least 2cm on the width and the whole unit becomes significantly smaller
If that happens then a small in situ battery with remote recharge option is of interest (but then you can't change it in the field, I carry two sets of AA;s for the spotter when I go out as I tend to leave it turned on around my neck

Ahh! I see - I've just had another look at the photo of the guts. This is what you need:
http://www.ebay.co.uk/itm/10PCS-RCA...389?pt=LH_DefaultDomain_0&hash=item23263599f5
The original unit should come off the board OK.
And there must be loads of panel mounted pots with switches available:
