kryton groove build questions

Hey guys!! So I was bored and decided I wanted to do another laser build. I started going through my boxes of parts and hosts. I found a couple kryton groove hosts I bought prolly over a year ago. I have yet to do anything with them. They are a pretty unique host. I am currently trying to figure out the contact board situation. Does anybody know the size contact board I need? I don't have an inner diameter caliper. Also if someone has one.. do you/can you get a pic of the mounted contact board? I searched the forum a bit and was unable to find any useful info. Also where would be a good place to order said contact board. I was gonna contact Jeff... FP... but he hasnt been around. We seem to be in a builder slump. It's not what it was when I started this hobby over two years ago!!

Hi Im still building

You need a 16.8 mm contact board. Although its expensive you can get one from Survival lasers. As you mentioned FP might still have some, or failing that you could try Marcuspeh.

One other option would be to try DX, Fasttech, Kaidomain, Banggood and Gearbest.
I will try to find a link to something suitable.

Last resort would be to strip the components from a cheap 16.8 - 17 mm flashlight driver or to cut one out yourself from a piece of PCB. In the case of the later you can just put a screw through the middle of the board to act as the positive contact. Heres an example of a groove contact board mod from Kenom



This is a picture of one of the contact boards I used in my builds (now sold out at Intl-outdoor unfortunately) and a picture of the inside of the host with the board installed. Interestingly Intl-outdoor ran out of these boards around the time Marcuspeh started selling them.





Solder the board (as above) with a spring and leads first and use 2 part epoxy around the edge of the underside of the board, side where the spring is, and carefully lower it into the tube until it reachs the inside lip. Push the board down firmly into place and make sure the positive wire is not touching the inside. Take a 1.25 mm drill bit and drill a hole next to the negative contact pad through the board and lip of the host. Use a 1.3 mm brass nail and hammer it through the board and lip - helps if you pre-solder the head of the nail first. Once the nail is in place and touching the negative pad, cut a small strip of solder and drop it into the hole on top of the nail and next to the negative pad. Holding the wires out of the way, take a big soldering iron head and touch it to the nail head and board. The solder will flow and make contact. Take care here not to desolder the negative wire ie hold it well in place and be quick. If you turn the laser over and look in the battery compartment you will see the nail poking through, this needs to be bent over with ie a screwdriver and hammered down against the lip - dont let it touch the spring! Doing this has two purposes; one it reinforces the board to host physical connection and secondly it will allow the battery to make contact with the spring - it cant if the nail is in the way!

If you need any further help just let me know, Ill also try to dig out some more pics of the process.:beer:

Hi Fenny ,
if you want i have 16.8 MM contact boards i can send you some if you PM me with your address no problem .. Always glad to help build..

Finally found them, here you go:

http://www.kaidomain.com/p/S024124.17mm-x-1_6mm-Partition-Boards-for-LED-Flashlight-Drivers-5-pcs :beer:

I ordered these once before. The quality is ok, but the ones I received were a little corroded. If that happens you can put them in some lemon juice and salt to remove the oxide from the contacts. Other than that they work fine.:beer:

Not to de-rail your thread 10fenney, but since the subject of battery contact boards has come up, these 16.8/17mm boards pictured below are the best I've come across.
I bought them from Mrcrouse who unfortunately isn't around anymore, and I haven't seen this layout style anywhere else. If anyone knows where to get these please share, as they are a nice high quality board.

We can always use another source for quality components; I'd probably be up for a few, and I'm sure that if the price was right, others would be in the market for some also. :yh:
