Idea for Blerky
« on: April 28, 2017, 01:48:55 PM »
Here,s a picture of my NV set up. The upside down picatinny mounts are the thumbscrew type. It makes things easier to fit the assembly to the rail without having to use keys. The same goes for the torch mount. The advice given to me by the suppliers of the camera was to focus it , off the scope, at 10 feet. Some people solder all the connections to a piece of circuit board but I kept all the connectors as they come to facilitate easy replacement if one part fails.

It's lovely, Baggy.

VERY neat.

What sort of camera have you used? It's really neatly wired.

What does the rig look like from the dangerous end?

Were you not concerned that if the screen fails it'll mean damaging the project box to replace it?

I used a KPC-E700PUB camera from Sure24 , the night vision specialists. Expensive but worth it. I also used a 5" 800 480 TFT LCD HD reversing screen . Mine has performed faultlessly. My mate, on the other hand bought a cheap screen and it soon had a few faulty pixels. In fact, he replaced it this week and straight away it blew four pixels. Boy, is he pissed off  :'(.
Now I suppose I better take another piccy, just for you  ::)

The screen is glued on with plastic glue but I reckon it would prise off . If not, project boxes are cheap. Mine measures 150mm x 100 x 60. You,ll see I also glued some Velcro to the back. I have a small spare battery that I can use if the main one runs out whist shooting although this is unlikely . The torch mount is an offset QD item.

I went for a Sony Effio 700TVL Camera via eBay. It's another one that I have seen recommended for the job.

I also used a 5" 800 480 TFT LCD HD reversing screen

Same here, again from eBay. 16.79 so it's almost "disposable"!

Shame about your mate's experiences.

Yeah, a project box is a better idea than that climbing bag I've used. I think I'll crib your idea.

The torch mount is an offset QD item.

Why offset? Is that deliberate?

How did you attach the box to the rail? Glue?

Your camera is the right one as is the screen. I fixed the box with a couple of 4mm screws and penny washers to spread the load. The offset mount was one i just happened to have. You,ll notice the torch is mounted to a piece of picatinny fitted to the front of the main rail. What type of torch did you buy?

My torch is a UF T20 Cree jobbie. Only on/off and focus to play with.

If I mount it high away from or even forward of the scope will it reduce flare?

Well, I invested in a project box.

To make the tidiest, most stable set up I also had to get a couple of high mounts and a piece of Weaver/dovetail/picatinny (no idea what the difference is!) rail.

So now I have my battery and wires in the project box and my screen sitting in a recess in it.

It's looking good.

I re-focused the camera at 10 yards. I have yet to try it out at bigger distances and in the dark but it's looking very usable, as good (if not better) than my first attempt at setting up and zeroing etc.

But I have made mistakes along the way:

  • I positioned the battery with the switch on the top and drilled the box accordingly. This means that the switch and socket on the battery are not sheltered from the rain.
  • My screen is held in the recess using a couple of Velcro straps as I can't find my glue. This is easily sorted.
  • I've ended up buying mounts that I haven't used. But you live and learn, eh?
  • To enable my torch to be removed easily it's on a mount that offsets it from the scope/barrel and, as a result, the whole thing is not balanced evenly. This is not the end of the world, just something not to do again or to be addressed if I find a better mount.

I'm hoping to get out again on Tuesday night. I can hardly wait!
