hi there i was wondering if any of you have removed the module from inside a standard dx green laser pen, as i would like to make my laser more compact. the last module i tried to remove (forcefully removed to use host as barrel) required much banging and i am sure if the module was previosly...

hi there i am currently woking on a project that houses as many geeky things inside a wallet, ive got a hv supply, lasers and led torch, but for the real geek vibe i need something that is microcontrolled, ive got access to an avr programmer and any chips you suggest, throw some ideas this way...

hi there. this is a sircuit designed for an led, from this site http://www.instructables.com/id/Circuits-for-using-High-Power-LED_s/?ALLSTEPS it uses a couple of transistory mosfet things and i was wondering if any of you would know how well it would work in a laser. (hopefully some one can work...

i'm sorry if i am missing something here but that leg on diodes is there for regulation, is there a easy way to use it.

well according to the forum stat thing a new record has been set for number of members online -- 121 members --- wow i didnt know this hobby was so popular

hey this is not an idea i will take on any time soon but wouldn't it be cool if..... you could get a laser burner down to the size of an aixiz module. I know that coin cell batteries cant get any way near 420Ma and are low voltage. but why not go lipo, look here...

hi there i have conflicting information on the ratio to make yellow, would 20mw green and 200mw red make a nice vibrant yellow?

hi there i am powering my dx 20 "true" with 3 volt powersuply (mains power) and the beam is super vivid even in a well lit room. it mode hops on power on but then stableises, is this normal?. it is so bright itis uncomfortable to look at the dot (i orderedthe 20mw becuase i thought it would be...

hi there latly i have been playing with my dx 20 and i have noticed that when i run the laser off of a powersuply the beadm is very visible even in a well lit room, this visibility (well to that extent) dosnt happen even with fresh batteries .. this seems beculiar to me because same voltage...

hello all, on this forum there is allot of bad words towards true dx and their divergences - but i was looking down the end of the laser, as you do (no batteries no flame please) and i saw that there is a focusing arangement inside (brass module) anyone with bad divergance i prasume pry off the...

hi there, if i use standard polarisation film roughly how much power will i lose from my beam. (ball park fgures are fine)

i know this question is old hat now but is there a cheap way of combining red and green - i have seen the gb on optics but i dont have 30$ to spend are there any ther ways - or maby places to scavange these optics

hello, at the mo i dont have the time to post pictures but there is an interesting effect of a aser on a zip tie. It works like this : my dx70 is focused to super fine dot on the shiny side of a black zip tie. the reflection of which is projected onto a screen (my door) and all sort of...

I have found a laser diod 75W pulsed only roughly 60$  uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6541866 they say they are 75W pulse lasers. ciould these be incorperated into a pionter. maybe they can be ran at .5 W constantly. any ideas
