thanks mike, it is a great feeling when you build your own and it works ha ha, now my next project is to build the torch for spotting,i,ve ordered all the parts and i,m just waiting for them to arrive,

got to be honest some of the night vision kits on here have really got me thinking,some of them are amazing and mine looks like something you would get out of a lucky bag lol,

cant believe just how interesting this homemade night vision saga really is, cant stop reading up on it and trying different things,also its nice to know there are some very helpful people on here willing to help you out,,its an awsome site bud

all the best Evo

It looks good to me mate, at the end of the day if it works and your happy with it what more could you ask for, nobody knocks a tryer and this is the best place to show off your own
Home brew kit.

It might even help someone else start their own diy setup

And yes very addictive :mrgreen: .

it is addictive mike,i am gonna put a parts list together for the lads who have pm,d me, the good thing is the whole setup will cost £100-£120 for the full build and it is superb for airrifle distances so i think a few of the lads will be putting it together,

anyway thanks again for ya encouragment,,now for my next IR project lol,

all the best Evo (Bob)

Excellent results there Bob :thumbup:

You can improve the existing 502b torch you have there as well mate. You can focus the lens to give you more distance if you wanted to.

1, Remove the head and the little ally ring that holds the lens in and seats the reflector, leave the lens in place.
2, You'll need a spacer about 2mm to 3mm deep (a suitable combination of washer/shim or rubber o-ring works well) of the same diameter as the ally ring.
3, Put this directly behind the lens and screw the ally ring back in on top of the new washer/o-ring.

Putting the bezel/head and reflector back in you will find that it will only catch on a couple of threads to the main torch body, make sure you screw it back on straight so you don't ruin those threads ! If it won't go on first time then the washer/o-ring is most likely a little too thick and you may need to back off on thickness a little. The advantage of the o-ring style is that you can squeeze it a little.

What this does is get the LED nearer to the correct back focal length of the new lens you put in there.

What it will give you is a narrower, more intense and focussed beam = more distance.

Try it, and let us know how you get on buddy.

...is this a pistol in my hand, or am I just pleased to see you ?

Edit : I have made a mistake on the 501 advice :oops: Official Plonker, me !

The lens needs to be closer to the LED not, further away. The reflector needs trimming back to bring the back focal length on the 28mm lens right.

I will leave it to the lads with more experience on this one to help you.

I'm off to kill myself with a piece of plasticine and a tomato :eh:
