The simple audio plug with a silicone blob backing is more in line with what I had in mind - a simple safety mod for a simple host. A reed switch, on the other hand, will be on my wish-list for my next-next-next level futuristic 22nd Century host, lol.

ok, I think the 2.5mm audio TS plug was what I saw on a higher-end Chinese laser somewhere. I just didn't know exactly what type of plug it was using. Thank you guys!

Do some laser pointers have a 'safety pin' which acts like a 'key' so that when removed or pulled out of its hole/port, the circuit is broken, rendering the laser pointer without power? 1) What type of 'pin' can be used? What is it called when looking at the Mouser catalog? 2) Can the hole...

ok, thank you. 4.5A is plenty enough.

hello LT17, I started a private conversation with you to ask more questions (I assume this is how you send a PM) Never used this function before so don't know if I did it right or whether you got it.

Hello LT17, Your complete hosts always look great - love the pictures you post here. Is your work dedicated only to complete hosts or do you also do machine work on individual parts (heatsink, head, tailcap, battery tube, etc.) sent to you by forum members? If only complete hosts, are the...

ok, thank you. pm sent.

ok, thank you Alaskan. I will consider the pros/cons you mentioned. FT17: About your really nice heat sinks: Which host were these meant for? Thank you.

That was my first plan but now I prefer to put the heatsink inside the tube - if I can of course, to make the whole thing smaller, shorter and less bulky although I'd lose some heatsink mass with this design. I just don't know about using metal tape as an air gap filler. Or maybe if I don't...

LT17 - ok, thank you for the info.

LT17, about your custom primary heatsinks, are they one piece (front piece for diode and lens) or two piece (front piece and back piece)? Thank you.

The following questions are for using a large heatsink (e.g. host body or diode heatsink) for an SXD driver running at 4+ Amps: 1) Which component(s) of the driver needs to be heatsinked the most? What does that component look like on the board? Since many rectangular driver boards have...

A big thank you to Icecruncher and Lifetime for your advice. I noticed the 3.2V on many 32650 batteries and wondered about it but didn't know what to think. Your info will steer me in a different direction now. Great info. Thank you!

Question: How many amps will the tail switch in the S4X handle? Thank you for your help!

Hello Lifetime, Nice host for a really great price, especially with the custom head! Question: How many amps will the mag switch handle? Which brand of 32650 battery do you recommend these days.....TrustFire, FCDC, Liitokala, or.......? thanks.

Hello, tried to find answer to this question in previous threads but couldn't find a discussion on this sibject. Jayrob laser kits have used Maglites up to 3 Amps but not 4.5 Amps. Maybe his flashlights used high amps but I don't know if he modded the switch to handle the hi amps. 1) I am...

Thanks guys! Great video!

I assume a 445nm 7W using a G2 or G8 has a beam so wide at 100 ft that it cannot pop a black balloon? Has anyone tried?

Excellent Gary, thank you for your explanation and pictures! Looks like an easy mod to accomodate the larger 25mm DTR copper heatsink !

hello. great site with really good stuff! About the S4X 20mm adapter: 1) do you have a 25mm? I notice DTR has the 7W 450nm emitter mounted in 25mm copper but not 20mm. 2) is there enough meat on the inside of your 20mm adapter to lathe it out to 25mm? 3) do you provide the above lathe work? 4)...
